因為老闆說要試試看用GPU 來跑postgresql 威力
手邊剛好有一張 geforce gt 720
一開始沒想太多，看到有這張卡的驅動程式，然後CUDA也有支援
就直接從桌機拔下來，接去LAB Server ，然後就開始一連串的難關了...
<!--more-->
整個過程大致上分為四個步驟
### 安裝 nvidia driver
### 安裝 CUDA
### 安裝 postgresql
### 安裝 pgstrom
************
#### 安裝 nvidia driver
試過幾種方法，最後還是覺得用apt來安裝比較妥當
先新增repository、update、裝driver
```
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
```
然後用這個指令
```
ubuntu-drivers devices
```
看一下現在的驅動程式狀態
```
administrator@hqdc032:~/pg-strom$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001288sv0000174Bsd0000326Bbc03sc00i00
vendor : NVIDIA Corporation
model : GK208B [GeForce GT 720]
driver : nvidia-driver-410 - third-party free
driver : nvidia-driver-418 - third-party free
driver : nvidia-340 - distro non-free
driver : nvidia-driver-430 - third-party free recommended
driver : nvidia-driver-390 - third-party free
driver : nvidia-driver-415 - third-party free
driver : xserver-xorg-video-nouveau - distro free builtin
```
我這張卡，可以裝到 430 的版本，
接下來就繼續安裝驅動程式、裝完之後重開機
```
sudo apt install nvidia-driver-430
sudo reboot
```
這時候，應該可以看到一些基本資訊
```
lsmod|grep nvidia
```
大概長這樣
```
nvidia_uvm 798720 0
nvidia_drm 45056 3
nvidia_modeset 1093632 7 nvidia_drm
nvidia 18194432 258 nvidia_uvm,nvidia_modeset
drm_kms_helper 172032 1 nvidia_drm
drm 401408 6 drm_kms_helper,nvidia_drm
ipmi_msghandler 53248 2 ipmi_devintf,nvidia
```
到這邊 nvidia 驅動程式安裝完成，接下來安裝 cuda
#### 安裝 CUDA
同樣採用官網下載deb 回來安裝的方法
到這邊 https://developer.nvidia.com/cuda-downloads
依照自己的系統選擇
我選擇 Linux -- x86_64 -- Ubuntu -- 18.04 -- deb(local)
畫面上就會有安裝步驟，照著做就沒問題了
```
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget http://developer.download.nvidia.com/compute/cuda/10.1/Prod/local_installers/cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-10-1-local-10.1.243-418.87.00/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda
```
一樣，安裝完成後重新開機，然後來編譯一個 deviceQuery 的小程式來看看資訊
```
cd /usr/local/cuda-10.1/samples/1_Utilities/deviceQuery
sudo make
```
會產生一個叫 deviceQuery 的執行檔，執行後，會有相關資訊
```
administrator@hqdc032:/usr/local/cuda-10.1/samples/1_Utilities/deviceQuery$ ./deviceQuery
./deviceQuery Starting...

```
到這邊， CUDA 也安裝完成，再來是簡單的 postgresql 11
#### 安裝 postgresql 11
步驟差不多，就是新增repository，然後選擇要安裝的套件，不過套件的選擇和平常安裝postgresql 不太一樣
```
sudo apt install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo apt update
sudo apt install postgresql-client-11 postgresql-11 postgresql-server-dev-11 postgresql-common libicu-dev
```
跑完之後，就直接啟動 postgresql service 就可以了
再來是最麻煩的 pgstorm
#### pgstorm
話說，這軟體到底叫啥名字？ pgstrom , pg-strom ? 看起來就像是拼錯字啊！ =.=
https://github.com/heterodb/pg-strom
先 git clone 回來，然後make、make install
講是很簡單，但是一開始碰到很多問題，有去github 跟開發團隊回報，幸好有回覆我..
總之，目前在ubuntu 18.04 + postgresql-11 的環境下編譯是沒有問題了
```
git clone https://github.com/heterodb/pg-strom.git
cd pg-strom
make && sudo make install
```
再來設定一下 postgresql
#### postgresql 相關設定
需要修改一下postgresql.conf，來指定載入 pgstrom 的 library
官方是這麼說的
```
PG-Strom module must be loaded on startup of the postmaster process by the shared_preload_libraries. Unable to load it on demand. Therefore, you must add the configuration below.
```
修改 /etc/postgresql/11/main/postgresql.conf
加入一行
```
shared_preload_libraries = '$libdir/pg_strom'
```
然後還有其他三個要修改，不過這個不改不會影響pgstrom 的啟動
看狀況要不要修改吧
```
max_worker_processes = 100
shared_buffers = 10GB
work_mem = 1GB
```
修改完後，重新啟動 postgresql service 有沒有很感動！？我終於可以享受用GPU跑SQL Query 的快感啦！！！
咦？？等等，為什麼postgresql service 沒起來！？
看一下 /var/log/syslog
```

```
啊幹！pg-strom 不支援這張GT 720啦！
https://github.com/heterodb/pg-strom/wiki/001:-GPU-Availability-Matrix
簡單說，就是至少從 GTX 1080 起跳，其他都不用想了
幹，花了兩天的時間在弄這東西，結果明明一開始就應該要先檢查的相容列表卻沒有檢查...
好了，現在就看准不准我買一張 GTX 1080 來測試了....
只是這價格嘛...嗯咳，不是我該煩惱的問題了..

這篇繼續講 pgbarman 透過 rsync/ssh 來備份 postgresql 資料庫的方式
<!--more-->
其實呢，透過 ssh 的方式來做備份，雖然最後有弄出來，但是我不知道到底做了什麼事才搞定
也許要重新安裝一台來測試看看
所以就簡單說一下邏輯、記得的指令、還有最後的config
##### ssh
在db server 上，讓 barman server 可以用barman 帳號透過ssh key 登入 postgres 帳號
然後在 barman server 上，讓 db server 可以用postgres帳號透過 ssh key 登入 barman 帳號
##### barman.d
在/etc/barman.d/ 底下新增一個hqs019-ssh.conf
內容如下
```
[hqs019-ssh]
description = "hqs019 (via SSH)"
ssh_command = ssh postgres@hqs019
conninfo = host=hqs019 user=barman dbname=database_name
backup_method = rsync
reuse_backup = link
parallel_jobs = 5
archiver = on
```
##### postgresql.conf
新增跟barman有關的設定如下
```
### for barman test
wal_level = 'archive'
archive_mode = on
archive_command = 'rsync -a %p barman@192.168.11.192:/var/lib/barman/hqs019-ssh/incoming/%f'
```
理論上這樣就可以了，但是實際上碰到很多問題
主要都是這個錯誤訊息
```
WAL archive: FAILED (please make sure WAL shipping is setup)
```
碰到這狀況，google 都會告訴你，在 postgresql.conf 裡面 archive_command 的路徑，要和 barman server 上的設定一致
![](https://i.imgur.com/3dMdytn.png)
但是我的路徑就沒有問題，還是一直跳這個錯誤
接著我又在 barman server 這邊做了這些事情
```
barman check hqs019-ssh
barman check hqs019-ssh
barman check hqs019-ssh
ssh postgres@hqs019
barman check hqs019-ssh
barman show-server hqs019-ssh |grep incoming_wals_directory
barman show-server all
barman cron
barman switch-xlog hqs019-ssh
barman check hqs019-ssh
psql -c 'SELECT version()' -U postgres -h hqs019
psql -c 'SELECT version()' -U barman -h hqs019
psql -c 'SELECT version()' -U barman -h hqs019 -d database_name
barman check hqs019-ssh
barman check hqs019-ssh
barman bachup hqs019-ssh
barman backup hqs019-ssh
barman list-backup hqs019-ssh
df -h
barman backup hqs019-ssh
barman show-server hqs019
barman check hqs019
```
前面幾次 barman check 一直都不通過
然後在 barman cron / barman switch-xlog hqs019-ssh (其實這個動作我做過好多次)
想說確認一下psql 連接是不是正確(也的確正確無誤)
接著第一次 check 還是FAILED 喔，過沒多久我再跑一次 check 又正常了... WTF !!!
只要check 正常，接著跑 backup 應該就會很順利
```
barman@barman:~$ barman backup hqs019-ssh

barman@barman:~$
```
檢查一下狀態
```
barman@barman:~$ barman list-backup hqs019-ssh
hqs019-ssh 20190823T113229 - Thu Aug 22 20:38:13 2019 - Size: 132.9 GiB - WAL Size: 0 B (tablespaces: tablespace_a:/var/lib/postgresql/10/main/tablespace_A, tablespace_b:/var/lib/postgresql/10/main/tablespace_B)
```
然後為了驗證是不是跑增量備份，所以再執行一次 backup
```
barman@barman:~$ barman backup hqs019-ssh
Starting backup using rsync-exclusive method for server hqs019-ssh in /var/lib/barman/hqs019-ssh/base/20190823T132124

0000000100000264000000B9.00000028.backup
barman@barman:~$
```
可以發現第一次跑了一個多小時，第二次只跑了五秒鐘 (因為資料庫根本沒異動)
到這邊雖然功能驗證沒有問題，可是不知道怎麼弄出來的，還是讓我很阿雜..
應該會再找時間來重作一台，然後順便測試看看restore
update
剛剛又做了一次測試，config 都一樣
果然要先做 barman cron/barman switch-xlog hqs019-ssh
然後再做 barman check 就可以通過了
在文件裡面很少提到這部份，筆記一下，用ansible 去跑的時候才不會忘記

很久以前就有看到這個用來備份postgresql 的 pgbarman
https://www.pgbarman.org/
前幾天老闆在slack 上面又提到，所以這次就花了點時間來玩玩看
不過呢，雖然有弄起來，但是還真不知道有些問題是怎麼解決的...
<!--more-->
pgbarman 的備份有分兩種
streaming && rsync/SSH
原理就不說了，我一直沒搞懂 postgresql 的 streaming ..
依照官方網站上的說法，比較推薦 streaming 備份的方式
原因是，設定相對簡單，WTF !
```
On a general basis, starting from Barman 2.0, backup over streaming replication is the recommended setup for PostgreSQL 9.4 or higher
The reason why we recommend streaming backup is that, based on our experience, it is easier to setup than the traditional one
```
事實上呢，設定的確是很簡單，可是有個致命的缺點
```
Because Barman transparently makes use of pg_basebackup, features such as incremental backup, parallel backup, deduplication, and network compression are currently not available. In this case, bandwidth limitation has some restrictions - compared to the traditional method via rsync.
```
如果要做差異/增量備份， streaming backup 不能做
所以每次備份都是完整備份，也因此，barman server 需要準備很大的硬碟空間
以我測試的資料庫來說，一次備份，目前是133G ，如果一天四次，保留七天
就需要 133 x 4 x 7 = 3724G
咦，這樣看起來，其實也還好啦 XDD
______
現在開始設定的部份
#### 設定 postgresql server
IP: 192.168.11.19
hostname: hqs019
##### 在postgresql 建立相關帳號
streaming backup 需要先在postgresql Server 上建立一個具有 superuser 權限的帳號
以及一個用來做replication 的資料庫帳號
這裡就簡單帶過
```
sudo su - postgres
psql
create user barman with login superuser login password 'barmanpassword';
CREATE ROLE stream_barman WITH REPLICATION PASSWORD 'password' LOGIN;
```
##### 鄉改 pg_hba.conf
然後修改 pg_hba.conf，加入底下兩行
```
# for barman test
host database_name barman 192.168.11.192/32 md5
host replication stream_barman 192.168.11.192/32 md5
```
當然，如果不考慮安全性問題， md5 直接改成用 trust ，可以省去一些麻煩。
##### 修改 postgresql.conf
接著修改postgresql.conf
```
### for barman test
max_wal_senders = 5
max_replication_slots = 3
wal_level = 'archive'
archive_mode = on
```
重起 postgresql service
#### 設定barman server
IP: 192.168.11.192
hostname: barman
##### 安裝 barman
barman 在18.04 中，已經被放到標準repository 中
所以只要直接
```
sudo apt install barman
```
就可以了
##### 設定 barman.conf
安裝完成後，在/etc/barman.d/ 底下會有兩個範例檔案
```
streaming-server.conf-template
ssh-server.conf-template
```
複製 streaming-server 檔案
```
sudo cp /etc/barman.d/streaming-server.conf-template /etc/barman.d/hqs019.conf
```
內容如下
```
[hqs019]
description = "hqs019 "
conninfo = host=192.168.11.19 user=barman dbname=database_name password=barmanpassword
streaming_conninfo = host=192.168.11.19 user=stream_barman dbname=database_name password=password
backup_method = postgres
retention_policy_mode = auto
streaming_archiver = on
slot_name = barman
```
接著修改 /etc/barman.conf
```
[barman]
barman_user = barman
configuration_files_directory = /etc/barman.d
barman_home = /var/lib/barman
log_file = /var/log/barman/barman.log
log_level = DEBUG
compression = gzip
immediate_checkpoint = true
basebackup_retry_times = 3
basebackup_retry_sleep = 30
last_backup_maximum_age = 1 DAYS
```
基本上這樣就設定完成了
##### 檢查設定
barman 有一些指令可以用來檢查目前的設定
barman show-server hqs019 可以看到所有的設定，這裡的 hqs019 跟 barman.d/hqs019.conf 裡面用"[ ]" 包起來的名稱要一致
```

restore 的部份，暫時沒有測試，我想應該是要找時間測試看看怎麼還原才對
不過呢，前面有提到，用streaming backup ，每一次備份都是完整備份，非常的佔用空間、時間、頻寬
所以還是要來試試看用rsync/SSH 備份的機制

<p>之前總部和分公司之間 是用buffalo 的小AP 灌 openwrt</p> <p>因為老闆說要試試看用GPU 來跑postgresql 威力</p>
<p>然後用strongswan 來打 IPSEC site to site VPN</p>

<p>因為工作上的需要，要修改client端的 /etc/environment 檔案</p> <p>之前總部和分公司之間 是用buffalo 的小AP 灌 openwrt</p>
<p>在有權限使用proxy 服務的user的環境中，加入proxy 的設定</p> <p>然後用strongswan 來打 IPSEC site to site VPN</p>
<p>原本的清單中，有host/user/ip 這幾個值可以拿來判斷</p> <p>config 看起來不是很難 (只是看起來)</p>
<p>proxy server 那邊是採用ip 來控制，所以這邊也跟著用 ip 來判斷要不要修改 /etc/environment</p> <p>但是實際上已經找不到當初的文件</p>
<p>所以要維護很困難(光那些RSA KEY 就不知道為何、如何產生)</p>
<p>後來採購了兩台edgerouter X 做測試</p>
<a href="/post/ansible-run-task-depends-on-ipaddr/" class="more"></a> <p>也用openvpn 成功的建立了 site to site VPN</p>
<p>本來想說 openvpn 已經夠簡單了</p>
<p>今天看到文章說用wireguard 可以更簡單</p>
<p>於是研究了一下，發現還真的很簡單！</p>

<p>之前在LAN/windows環境下，一直都是用ultravnc/winvnc/tigervnc之類的VNC軟體</p> <p>最近有個任務，需要大量安裝client</p>
<p>想用PXE來處理，只要user開機按F12(acer 桌機) 選擇PXE Boot</p>
<p>但是如果要過 internet ，就會碰到各種開port的問題</p> <p>然後選擇OS版本，就可以自動進行安裝</p>
<p>在這種環境下，就有了當時 teamviewer 的橫空出世</p> <p>安裝完成後，會自動重新開機，接著就用ansible來做user環境設定</p>
<p>解決了開PORT的問題，讓被控端(通常是資訊技術相對弱勢，需要接受幫助的一方)不需要懂太多</p> <p>PXE的部份本來是沒有什麼問題，自動安裝系統的部份都做好了</p>
<p>只要下載teamviewer被控端，開啟後報ID 給協助者就好了</p> <p>可是因為這次的量比較多，想說讓每一台在完成PXE安裝後的第一次重開機</p>
<p>就送出一封郵件來通知我，說已經完成安裝，可以執行ansible 了</p>

<p>前幾天接的一個case</p> <p>因為工作上的需要，要修改client端的 /etc/environment 檔案</p>
<p>因為費用的關係，所以沒有考慮用傳統定義上的伺服器(DELL R640)</p>
<p>改採用比較高階一點的洋垃圾，規格大概是 Intel E5-2680V2 x2 + 64G RAM + 128G SSD x2 (OS) + 960G SSD x4 (raid 10 , zfs)</p>
<p>storage 選擇QNAP NAS TS-932X + 960G SSD x 4 (raid 10 , NFS) + QNAP 10G Switch QSW-1280C-8C</p> <p>在有權限使用proxy 服務的user的環境中，加入proxy 的設定</p>
<p>既然storage這邊選用了10G的機種，伺服器上當然也要增加10G網卡</p> <p>原本的清單中，有host/user/ip 這幾個值可以拿來判斷</p>
<p>一樣，成本考量，就不用INTEL 了，買了這張 ASUS 10G 網卡</p> <p>proxy server 那邊是採用ip 來控制，所以這邊也跟著用 ip 來判斷要不要修改 /etc/environment</p>

<p>也導致原本負責處理盤點資產的同事困擾，因為跟手邊的紀錄已經對不起來了</p> <p>storage 選擇QNAP NAS TS-932X + 960G SSD x 4 (raid 10 , NFS) + QNAP 10G Switch QSW-1280C-8C</p>
<p>然後就變成要對資產的時候，需要一台一台登入，然後去下不同的指令，取得想要的硬體資訊，超級麻煩的！</p> <p>既然storage這邊選用了10G的機種，伺服器上當然也要增加10G網卡</p>
<p></p> <p>一樣，成本考量，就不用INTEL 了，買了這張 ASUS 10G 網卡</p>

<p>這是發生在一個夜黑風高的寂寥深夜&hellip;.. ( What The FXXX &hellip; )</p> <p>這幾天在玩ansible 時，碰到一個問題</p>
<p>來到這個環境之後，有一個很詭異的狀況一直困擾著我</p>
<p>在每個分公司，都會有一台伺服器作為KVM Host</p>
<p>上面跑兩台VM，一台作為ansible controller (目前沒作用)</p> <p>假如我有個yaml檔作為資料來源，檔名是 abc.yml</p>
<p>另一台作為這邊所謂的 &ldquo;Build Server&rdquo;</p> <p>大概長這樣</p>
<p>用途包含了DHCP Server / Proxy Server (squid3) / APT Proxy (squid-deb-proxy)</p> <pre><code> &quot;teams&quot;: [

<p>最近在重新規劃前人留下的backup爛攤子 <p>最近在測試metabase，記得幾個月前就有測試過</p>
各個伺服器統一備份到一台backup storage
想說如果每天能夠看到backup storage的磁碟用量的話 <p>但是當時的界面和現在的樣子差很多，看樣子改版還滿勤勞的</p>
就可以抓出備份空間成長速度、推估需要多大的磁碟空間
找了一些工具，結果發現 durep 這個 ubuntu 內建的工具 <p>所以這次改用docker來建立，根本五分鐘不到就建好了(挖鼻孔)</p>
基本上可以滿足我的需求</p>
<p>不過呢，很討厭的是，一進去就發現語系採用的是簡體中文</p>

<p>最近一直在玩 wireguard ，先前把各個分公司和總部的VPN 改用 wireguard 建立</p> <p>這篇繼續講 pgbarman 透過 rsync/ssh 來備份 postgresql 資料庫的方式</p>
<p>想說再打個VPN tunnel 來當跳板連 ptt 好了</p>
<p>因為wireguard 建立很簡單，而且又可以指定想要繞出去的路由，不會影響原本的網路環境</p>
<p>本來是在vultr 的VPS上面建立這個tunnel</p>
<p>但是那台VPS連去ptt 很頓，卡卡的</p>
<p>所以改用google cloud platform 的free tier 來做</p>
<p>反正只是拿來當跳板，不會有什麼流量、運算產生，可以一直保持免費的狀態</p>

<p>因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN</p> <p>很久以前就有看到這個用來備份postgresql 的 pgbarman</p>
<p>雖然說其實沒有什麼不好，但是畢竟不是我建立的，而當初的文件也都不見了</p>
<p>完全沒辦法了解當時設計的邏輯，造成後續debug 困難</p>
<p>可以想像一下，一台VPN router ping 不到remote、ping不到internet、甚至ping不到自己 是要怎麼debug !?(翻桌</p> <p><a href="https://www.pgbarman.org/">https://www.pgbarman.org/</a></p>
<p>之前買了兩台edgerouter X 拿來玩了一下 wireguard，感覺還不錯，不過只有測試到點對點</p> <p>前幾天老闆在slack 上面又提到，所以這次就花了點時間來玩玩看</p>

<description>&lt;p&gt;因為老闆說要試試看用GPU 來跑postgresql 威力&lt;/p&gt;
&lt;p&gt;手邊剛好有一張 geforce gt 720&lt;/p&gt;
&lt;p&gt;一開始沒想太多，看到有這張卡的驅動程式，然後CUDA也有支援&lt;/p&gt;
&lt;p&gt;就直接從桌機拔下來，接去LAB Server ，然後就開始一連串的難關了&amp;hellip;&lt;/p&gt;

<p>最近要開始測試client安裝 ubuntu 18.04 的 ansible playbook</p> <p>今天發生一件有點詭異的事情，本來應該要經過某個指令才會產生的檔案</p>
<p>因為要不斷的修正，所以想到一直有在自己電腦上執行的timeshift這個軟體</p> <p>居然不知為何自己產生了，在我記憶中沒有去執行過那個指令</p>
<p>可以很簡單快速的備份、恢復系統狀態</p> <p>翻了一下 bash_history ，裡面也只有下過哪些指令，沒有紀錄時間，完全沒有參考價值(攤手)</p>
<p>可是不知道為什麼，在ubuntu 18.04 上安裝就是會發生錯誤&hellip;.</p> <p>所以翻了一下網路，至少把這兩台主要跑ansible的機器的log功能補上紀錄所有指令以及時間的部份</p>

<p>想做一個 10G 的 LAB 環境出來已經很久了。</p> <p>最近在弄一台機器，想要把ubuntu 18.04 安裝在software raid上</p>
<p>只是礙於10G RJ45的卡太貴了，然後光纖的種類又太複雜</p>
<p>如果直接在淘寶購買，很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
<p>所以一直沒有付諸行動。</p>
<p>硬體的工作很久沒碰了，剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡，以在台灣的價格來說，算很便宜的 (550)</p>
<p>聊了一下，跟他請教了關於線材、光纖模塊的問題，回答也都很快很到位</p>
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p>
<p>就是到貨有點久，等了兩個禮拜左右，一直到昨天東西才寄到</p> <p>因為新開的機器大部分都是在proxmox上，所以很少碰實體機器了</p>
<p>今天就花了點時間測試一下</p> <p>結果在安裝過程中，做raid碰到一些問題，來紀錄一下</p>

<p>最近在測試metabase，記得幾個月前就有測試過</p> <p>想做一個 10G 的 LAB 環境出來已經很久了。</p>
<p>但是當時的界面和現在的樣子差很多，看樣子改版還滿勤勞的</p> <p>只是礙於10G RJ45的卡太貴了，然後光纖的種類又太複雜</p>
<p>如果直接在淘寶購買，很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
<p>所以這次改用docker來建立，根本五分鐘不到就建好了(挖鼻孔)</p> <p>所以一直沒有付諸行動。</p>
<p>不過呢，很討厭的是，一進去就發現語系採用的是簡體中文</p> <p>硬體的工作很久沒碰了，剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡，以在台灣的價格來說，算很便宜的 (550)</p>
<p>聊了一下，跟他請教了關於線材、光纖模塊的問題，回答也都很快很到位</p>
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p>
<p>就是到貨有點久，等了兩個禮拜左右，一直到昨天東西才寄到</p>
<p>今天就花了點時間測試一下</p>

<p>之前在LAN/windows環境下，一直都是用ultravnc/winvnc/tigervnc之類的VNC軟體</p> <p>最近有個任務，需要大量安裝client</p>
<p>想用PXE來處理，只要user開機按F12(acer 桌機) 選擇PXE Boot</p>
<p>但是如果要過 internet ，就會碰到各種開port的問題</p> <p>然後選擇OS版本，就可以自動進行安裝</p>
<p>在這種環境下，就有了當時 teamviewer 的橫空出世</p> <p>安裝完成後，會自動重新開機，接著就用ansible來做user環境設定</p>
<p>解決了開PORT的問題，讓被控端(通常是資訊技術相對弱勢，需要接受幫助的一方)不需要懂太多</p> <p>PXE的部份本來是沒有什麼問題，自動安裝系統的部份都做好了</p>
<p>只要下載teamviewer被控端，開啟後報ID 給協助者就好了</p> <p>可是因為這次的量比較多，想說讓每一台在完成PXE安裝後的第一次重開機</p>
<p>就送出一封郵件來通知我，說已經完成安裝，可以執行ansible 了</p>
<p>看似很簡單的一件事情，卻搞了我兩天&hellip;.</p>

<p>前幾天接的一個case</p> <p>因為工作上的需要，要修改client端的 /etc/environment 檔案</p>
<p>因為費用的關係，所以沒有考慮用傳統定義上的伺服器(DELL R640)</p>
<p>改採用比較高階一點的洋垃圾，規格大概是 Intel E5-2680V2 x2 + 64G RAM + 128G SSD x2 (OS) + 960G SSD x4 (raid 10 , zfs)</p>
<p>storage 選擇QNAP NAS TS-932X + 960G SSD x 4 (raid 10 , NFS) + QNAP 10G Switch QSW-1280C-8C</p> <p>在有權限使用proxy 服務的user的環境中，加入proxy 的設定</p>
<p>既然storage這邊選用了10G的機種，伺服器上當然也要增加10G網卡</p> <p>原本的清單中，有host/user/ip 這幾個值可以拿來判斷</p>
<p>一樣，成本考量，就不用INTEL 了，買了這張 ASUS 10G 網卡</p> <p>proxy server 那邊是採用ip 來控制，所以這邊也跟著用 ip 來判斷要不要修改 /etc/environment</p>

<p>然後又因為一直沒有添購新的硬碟，只能用這些快過保/已過保的撐著</p> <p>因為費用的關係，所以沒有考慮用傳統定義上的伺服器(DELL R640)</p>
<p>所以最近不斷的在更換機器內的硬碟，而且還沒有熱插拔！</p> <p>改採用比較高階一點的洋垃圾，規格大概是 Intel E5-2680V2 x2 + 64G RAM + 128G SSD x2 (OS) + 960G SSD x4 (raid 10 , zfs)</p>
<p>也導致原本負責處理盤點資產的同事困擾，因為跟手邊的紀錄已經對不起來了</p> <p>storage 選擇QNAP NAS TS-932X + 960G SSD x 4 (raid 10 , NFS) + QNAP 10G Switch QSW-1280C-8C</p>
<p>然後就變成要對資產的時候，需要一台一台登入，然後去下不同的指令，取得想要的硬體資訊，超級麻煩的！</p> <p>既然storage這邊選用了10G的機種，伺服器上當然也要增加10G網卡</p>
<p></p> <p>一樣，成本考量，就不用INTEL 了，買了這張 ASUS 10G 網卡</p>

<p>最近在重新規劃前人留下的backup爛攤子 <p>最近在測試metabase，記得幾個月前就有測試過</p>
各個伺服器統一備份到一台backup storage
想說如果每天能夠看到backup storage的磁碟用量的話 <p>但是當時的界面和現在的樣子差很多，看樣子改版還滿勤勞的</p>
就可以抓出備份空間成長速度、推估需要多大的磁碟空間
找了一些工具，結果發現 durep 這個 ubuntu 內建的工具 <p>所以這次改用docker來建立，根本五分鐘不到就建好了(挖鼻孔)</p>
基本上可以滿足我的需求</p>
<p>不過呢，很討厭的是，一進去就發現語系採用的是簡體中文</p>

<p>前幾天接的一個case</p> <p>因為工作上的需要，要修改client端的 /etc/environment 檔案</p>
<p>因為費用的關係，所以沒有考慮用傳統定義上的伺服器(DELL R640)</p>
<p>改採用比較高階一點的洋垃圾，規格大概是 Intel E5-2680V2 x2 + 64G RAM + 128G SSD x2 (OS) + 960G SSD x4 (raid 10 , zfs)</p>
<p>storage 選擇QNAP NAS TS-932X + 960G SSD x 4 (raid 10 , NFS) + QNAP 10G Switch QSW-1280C-8C</p> <p>在有權限使用proxy 服務的user的環境中，加入proxy 的設定</p>
<p>既然storage這邊選用了10G的機種，伺服器上當然也要增加10G網卡</p> <p>原本的清單中，有host/user/ip 這幾個值可以拿來判斷</p>
<p>一樣，成本考量，就不用INTEL 了，買了這張 ASUS 10G 網卡</p> <p>proxy server 那邊是採用ip 來控制，所以這邊也跟著用 ip 來判斷要不要修改 /etc/environment</p>

<p>最近一直在玩一些docker，不過老是會碰到歪果扔寫的東西，時區都不一致</p> <p>在ansible中，關於如何引用自定義的變數，一直讓我很頭疼</p>
<p>尤其是有牽涉到從外部導入yaml檔案時，更是常常讓我不知道到底該怎麼抓出想要的變數</p>
<p>這次還是用selectattr 來處理，希望下次能夠記得&hellip;</p>

<p>因為老闆說要試試看用GPU 來跑postgresql 威力</p>
<p>手邊剛好有一張 geforce gt 720</p>
<p>一開始沒想太多，看到有這張卡的驅動程式，然後CUDA也有支援</p>
<p>就直接從桌機拔下來，接去LAB Server ，然後就開始一連串的難關了&hellip;</p>
<p></p>
<p>整個過程大致上分為四個步驟</p>
<h3 id="安裝-nvidia-driver">安裝 nvidia driver</h3>
<h3 id="安裝-cuda">安裝 CUDA</h3>
<h3 id="安裝-postgresql">安裝 postgresql</h3>
<h3 id="安裝-pgstrom">安裝 pgstrom</h3>
<hr />
<h4 id="安裝-nvidia-driver-1">安裝 nvidia driver</h4>
<p>試過幾種方法，最後還是覺得用apt來安裝比較妥當
先新增repository、update、裝driver</p>
<pre><code>sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
</code></pre>
<p>然後用這個指令</p>
<pre><code>ubuntu-drivers devices
</code></pre>
<p>看一下現在的驅動程式狀態</p>
<pre><code>administrator@hqdc032:~/pg-strom$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001288sv0000174Bsd0000326Bbc03sc00i00
vendor : NVIDIA Corporation
model : GK208B [GeForce GT 720]
driver : nvidia-driver-410 - third-party free
driver : nvidia-driver-418 - third-party free
driver : nvidia-340 - distro non-free
driver : nvidia-driver-430 - third-party free recommended
driver : nvidia-driver-390 - third-party free
driver : nvidia-driver-415 - third-party free
driver : xserver-xorg-video-nouveau - distro free builtin
</code></pre>
<p>我這張卡，可以裝到 430 的版本，
接下來就繼續安裝驅動程式、裝完之後重開機</p>
<pre><code>sudo apt install nvidia-driver-430
sudo reboot
</code></pre>
<p>這時候，應該可以看到一些基本資訊</p>
<pre><code>lsmod|grep nvidia
</code></pre>
<p>大概長這樣</p>
<pre><code>nvidia_uvm 798720 0
nvidia_drm 45056 3
nvidia_modeset 1093632 7 nvidia_drm
nvidia 18194432 258 nvidia_uvm,nvidia_modeset
drm_kms_helper 172032 1 nvidia_drm
drm 401408 6 drm_kms_helper,nvidia_drm
ipmi_msghandler 53248 2 ipmi_devintf,nvidia
</code></pre>
<p>到這邊 nvidia 驅動程式安裝完成，接下來安裝 cuda</p>
<h4 id="安裝-cuda-1">安裝 CUDA</h4>
<p>同樣採用官網下載deb 回來安裝的方法</p>
<p>到這邊 <a href="https://developer.nvidia.com/cuda-downloads">https://developer.nvidia.com/cuda-downloads</a></p>
<p>依照自己的系統選擇</p>
<p>我選擇 Linux &ndash; x86_64 &ndash; Ubuntu &ndash; 18.04 &ndash; deb(local)</p>
<p>畫面上就會有安裝步驟，照著做就沒問題了</p>
<pre><code>wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget http://developer.download.nvidia.com/compute/cuda/10.1/Prod/local_installers/cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-10-1-local-10.1.243-418.87.00/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda
</code></pre>
<p>一樣，安裝完成後重新開機，然後來編譯一個 deviceQuery 的小程式來看看資訊</p>
<pre><code>cd /usr/local/cuda-10.1/samples/1_Utilities/deviceQuery
sudo make
</code></pre>
<p>會產生一個叫 deviceQuery 的執行檔，執行後，會有相關資訊</p>
<pre><code>administrator@hqdc032:/usr/local/cuda-10.1/samples/1_Utilities/deviceQuery$ ./deviceQuery
./deviceQuery Starting...

<p>到這邊， CUDA 也安裝完成，再來是簡單的 postgresql 11</p>
<h4 id="安裝-postgresql-11">安裝 postgresql 11</h4>
<p>步驟差不多，就是新增repository，然後選擇要安裝的套件，不過套件的選擇和平常安裝postgresql 不太一樣</p>
<pre><code>sudo apt install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo &quot;deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main&quot; &gt;&gt; /etc/apt/sources.list.d/pgdg.list'
sudo apt update
sudo apt install postgresql-client-11 postgresql-11 postgresql-server-dev-11 postgresql-common libicu-dev
</code></pre>
<p>跑完之後，就直接啟動 postgresql service 就可以了</p>
<p>再來是最麻煩的 pgstorm</p>
<h4 id="pgstorm">pgstorm</h4>
<p>話說，這軟體到底叫啥名字？ pgstrom , pg-strom ? 看起來就像是拼錯字啊！ =.=</p>
<p><a href="https://github.com/heterodb/pg-strom">https://github.com/heterodb/pg-strom</a></p>
<p>先 git clone 回來，然後make、make install</p>
<p>講是很簡單，但是一開始碰到很多問題，有去github 跟開發團隊回報，幸好有回覆我..</p>
<p>總之，目前在ubuntu 18.04 + postgresql-11 的環境下編譯是沒有問題了</p>
<pre><code>git clone https://github.com/heterodb/pg-strom.git
cd pg-strom
make &amp;&amp; sudo make install
</code></pre>
<p>再來設定一下 postgresql</p>
<h4 id="postgresql-相關設定">postgresql 相關設定</h4>
<p>需要修改一下postgresql.conf，來指定載入 pgstrom 的 library</p>
<p>官方是這麼說的</p>
<pre><code>PG-Strom module must be loaded on startup of the postmaster process by the shared_preload_libraries. Unable to load it on demand. Therefore, you must add the configuration below.
</code></pre>
<p>修改 /etc/postgresql/11/main/postgresql.conf
加入一行</p>
<pre><code>shared_preload_libraries = '$libdir/pg_strom'
</code></pre>
<p>然後還有其他三個要修改，不過這個不改不會影響pgstrom 的啟動</p>
<p>看狀況要不要修改吧</p>
<pre><code>max_worker_processes = 100
shared_buffers = 10GB
work_mem = 1GB
</code></pre>
<p>修改完後，重新啟動 postgresql service 有沒有很感動！？我終於可以享受用GPU跑SQL Query 的快感啦！！！</p>
<p>咦？？等等，為什麼postgresql service 沒起來！？</p>
<p>看一下 /var/log/syslog</p>
<pre><code>Aug 20 14:23:43 hqdc032 postgresql@11-main[11801]: Error: /usr/lib/postgresql/11/bin/pg_ctl /usr/lib/postgresql/11/bin/pg_ctl start -D /var/lib/postgresql/11/main -l /var/log/postgresql/postgresql-11-main.log -s -o -c config_file=&quot;/etc/postgresql/11/main/postgresql.conf&quot; exited with status 1:

<p>啊幹！pg-strom 不支援這張GT 720啦！</p>
<p><a href="https://github.com/heterodb/pg-strom/wiki/001:-GPU-Availability-Matrix">https://github.com/heterodb/pg-strom/wiki/001:-GPU-Availability-Matrix</a></p>
<p>簡單說，就是至少從 GTX 1080 起跳，其他都不用想了</p>
<p>幹，花了兩天的時間在弄這東西，結果明明一開始就應該要先檢查的相容列表卻沒有檢查&hellip;</p>
<p>好了，現在就看准不准我買一張 GTX 1080 來測試了&hellip;.</p>
<p>只是這價格嘛&hellip;嗯咳，不是我該煩惱的問題了..</p>

<p>居然不知為何自己產生了，在我記憶中沒有去執行過那個指令</p>
<p>翻了一下 bash_history ，裡面也只有下過哪些指令，沒有紀錄時間，完全沒有參考價值(攤手)</p>
<p>所以翻了一下網路，至少把這兩台主要跑ansible的機器的log功能補上紀錄所有指令以及時間的部份</p>
<p></p> <p>有的用 UTC，有的用localtime，就是沒碰到用 Asia/Taipei 的&hellip;.</p>

<p>想做一個 10G 的 LAB 環境出來已經很久了。</p> <p>最近在做一台老機器的P2V</p>
<p>只是礙於10G RJ45的卡太貴了，然後光纖的種類又太複雜</p>
<p>如果直接在淘寶購買，很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
<p>所以一直沒有付諸行動。</p>
<p>硬體的工作很久沒碰了，剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡，以在台灣的價格來說，算很便宜的 (550)</p>
<p>聊了一下，跟他請教了關於線材、光纖模塊的問題，回答也都很快很到位</p> <p>偏偏user說不能關機，所以我用dd + ssh 做線上移轉</p>
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p> <p>這部份有空再來寫</p>
<p>就是到貨有點久，等了兩個禮拜左右，一直到昨天東西才寄到</p> <p>只是因為原來的設定有用mdadm 做raid1</p>
<p>今天就花了點時間測試一下</p> <p>這部份導致移轉過去proxmox 後，會出現raid degrade 導致無法正常開機</p>

<p>這是發生在一個夜黑風高的寂寥深夜&hellip;.. ( What The FXXX &hellip; )</p>
<p>來到這個環境之後，有一個很詭異的狀況一直困擾著我</p>
<p>在每個分公司，都會有一台伺服器作為KVM Host</p>
<p>上面跑兩台VM，一台作為ansible controller (目前沒作用)</p>
<p>另一台作為這邊所謂的 &ldquo;Build Server&rdquo;</p>
<p>用途包含了DHCP Server / Proxy Server (squid3) / APT Proxy (squid-deb-proxy)</p>
<p>問題就發生在這台 Build Server 上&hellip;</p>

<p>最近在重新規劃前人留下的backup爛攤子
各個伺服器統一備份到一台backup storage
想說如果每天能夠看到backup storage的磁碟用量的話
就可以抓出備份空間成長速度、推估需要多大的磁碟空間
找了一些工具，結果發現 durep 這個 ubuntu 內建的工具
基本上可以滿足我的需求</p>

<p>這篇繼續講 pgbarman 透過 rsync/ssh 來備份 postgresql 資料庫的方式</p>
<p></p>
<p>其實呢，透過 ssh 的方式來做備份，雖然最後有弄出來，但是我不知道到底做了什麼事才搞定</p>
<p>也許要重新安裝一台來測試看看</p>
<p>所以就簡單說一下邏輯、記得的指令、還有最後的config</p>
<h5 id="ssh">ssh</h5>
<p>在db server 上，讓 barman server 可以用barman 帳號透過ssh key 登入 postgres 帳號
然後在 barman server 上，讓 db server 可以用postgres帳號透過 ssh key 登入 barman 帳號</p>
<h5 id="barman-d">barman.d</h5>
<p>在/etc/barman.d/ 底下新增一個hqs019-ssh.conf</p>
<p>內容如下</p>
<pre><code>[hqs019-ssh]
description = &quot;hqs019 (via SSH)&quot;
ssh_command = ssh postgres@hqs019
conninfo = host=hqs019 user=barman dbname=database_name
backup_method = rsync
reuse_backup = link
parallel_jobs = 5
archiver = on
</code></pre>
<h5 id="postgresql-conf">postgresql.conf</h5>
<p>新增跟barman有關的設定如下</p>
<pre><code>### for barman test
wal_level = 'archive'
archive_mode = on
archive_command = 'rsync -a %p barman@192.168.11.192:/var/lib/barman/hqs019-ssh/incoming/%f'
</code></pre>
<p>理論上這樣就可以了，但是實際上碰到很多問題</p>
<p>主要都是這個錯誤訊息</p>
<pre><code>WAL archive: FAILED (please make sure WAL shipping is setup)
</code></pre>
<p>碰到這狀況，google 都會告訴你，在 postgresql.conf 裡面 archive_command 的路徑，要和 barman server 上的設定一致
<img src="https://i.imgur.com/3dMdytn.png" alt="" /></p>
<p>但是我的路徑就沒有問題，還是一直跳這個錯誤</p>
<p>接著我又在 barman server 這邊做了這些事情</p>
<pre><code>barman check hqs019-ssh
barman check hqs019-ssh
barman check hqs019-ssh
ssh postgres@hqs019
barman check hqs019-ssh
barman show-server hqs019-ssh |grep incoming_wals_directory
barman show-server all
barman cron
barman switch-xlog hqs019-ssh
barman check hqs019-ssh
psql -c 'SELECT version()' -U postgres -h hqs019
psql -c 'SELECT version()' -U barman -h hqs019
psql -c 'SELECT version()' -U barman -h hqs019 -d database_name
barman check hqs019-ssh
barman check hqs019-ssh
barman bachup hqs019-ssh
barman backup hqs019-ssh
barman list-backup hqs019-ssh
df -h
barman backup hqs019-ssh
barman show-server hqs019
barman check hqs019
</code></pre>
<p>前面幾次 barman check 一直都不通過</p>
<p>然後在 barman cron / barman switch-xlog hqs019-ssh (其實這個動作我做過好多次)</p>
<p>想說確認一下psql 連接是不是正確(也的確正確無誤)</p>
<p>接著第一次 check 還是FAILED 喔，過沒多久我再跑一次 check 又正常了&hellip; WTF !!!</p>
<p>只要check 正常，接著跑 backup 應該就會很順利</p>
<pre><code>barman@barman:~$ barman backup hqs019-ssh

barman@barman:~$
</code></pre>
<p>檢查一下狀態</p>
<pre><code>barman@barman:~$ barman list-backup hqs019-ssh
hqs019-ssh 20190823T113229 - Thu Aug 22 20:38:13 2019 - Size: 132.9 GiB - WAL Size: 0 B (tablespaces: tablespace_a:/var/lib/postgresql/10/main/tablespace_A, tablespace_b:/var/lib/postgresql/10/main/tablespace_B)
</code></pre>
<p>然後為了驗證是不是跑增量備份，所以再執行一次 backup</p>
<pre><code>barman@barman:~$ barman backup hqs019-ssh
Starting backup using rsync-exclusive method for server hqs019-ssh in /var/lib/barman/hqs019-ssh/base/20190823T132124

0000000100000264000000B9.00000028.backup
barman@barman:~$
</code></pre>
<p>可以發現第一次跑了一個多小時，第二次只跑了五秒鐘 (因為資料庫根本沒異動)</p>
<p>到這邊雖然功能驗證沒有問題，可是不知道怎麼弄出來的，還是讓我很阿雜..</p>
<p>應該會再找時間來重作一台，然後順便測試看看restore</p>
<p>update</p>
<p>剛剛又做了一次測試，config 都一樣</p>
<p>果然要先做 barman cron/barman switch-xlog hqs019-ssh</p>
<p>然後再做 barman check 就可以通過了</p>
<p>在文件裡面很少提到這部份，筆記一下，用ansible 去跑的時候才不會忘記</p>

<p>很久以前就有看到這個用來備份postgresql 的 pgbarman</p>
<p><a href="https://www.pgbarman.org/">https://www.pgbarman.org/</a></p>
<p>前幾天老闆在slack 上面又提到，所以這次就花了點時間來玩玩看</p>
<p>不過呢，雖然有弄起來，但是還真不知道有些問題是怎麼解決的&hellip;</p>
<p></p>
<p>pgbarman 的備份有分兩種</p>
<p>streaming &amp;&amp; rsync/SSH</p>
<p>原理就不說了，我一直沒搞懂 postgresql 的 streaming ..</p>
<p>依照官方網站上的說法，比較推薦 streaming 備份的方式</p>
<p>原因是，設定相對簡單，WTF !</p>
<pre><code>On a general basis, starting from Barman 2.0, backup over streaming replication is the recommended setup for PostgreSQL 9.4 or higher
The reason why we recommend streaming backup is that, based on our experience, it is easier to setup than the traditional one
</code></pre>
<p>事實上呢，設定的確是很簡單，可是有個致命的缺點</p>
<pre><code>Because Barman transparently makes use of pg_basebackup, features such as incremental backup, parallel backup, deduplication, and network compression are currently not available. In this case, bandwidth limitation has some restrictions - compared to the traditional method via rsync.
</code></pre>
<p>如果要做差異/增量備份， streaming backup 不能做</p>
<p>所以每次備份都是完整備份，也因此，barman server 需要準備很大的硬碟空間</p>
<p>以我測試的資料庫來說，一次備份，目前是133G ，如果一天四次，保留七天</p>
<p>就需要 133 x 4 x 7 = 3724G</p>
<p>咦，這樣看起來，其實也還好啦 XDD</p>
<hr />
<p>現在開始設定的部份</p>
<h4 id="設定-postgresql-server">設定 postgresql server</h4>
<p>IP: 192.168.11.19
hostname: hqs019</p>
<h5 id="在postgresql-建立相關帳號">在postgresql 建立相關帳號</h5>
<p>streaming backup 需要先在postgresql Server 上建立一個具有 superuser 權限的帳號</p>
<p>以及一個用來做replication 的資料庫帳號</p>
<p>這裡就簡單帶過</p>
<pre><code>sudo su - postgres
psql
create user barman with login superuser login password 'barmanpassword';
CREATE ROLE stream_barman WITH REPLICATION PASSWORD 'password' LOGIN;
</code></pre>
<h5 id="鄉改-pg-hba-conf">鄉改 pg_hba.conf</h5>
<p>然後修改 pg_hba.conf，加入底下兩行</p>
<pre><code># for barman test
host database_name barman 192.168.11.192/32 md5
host replication stream_barman 192.168.11.192/32 md5
</code></pre>
<p>當然，如果不考慮安全性問題， md5 直接改成用 trust ，可以省去一些麻煩。</p>
<h5 id="修改-postgresql-conf">修改 postgresql.conf</h5>
<p>接著修改postgresql.conf</p>
<pre><code>### for barman test
max_wal_senders = 5
max_replication_slots = 3
wal_level = 'archive'
archive_mode = on
</code></pre>
<p>重起 postgresql service</p>
<h4 id="設定barman-server">設定barman server</h4>
<p>IP: 192.168.11.192
hostname: barman</p>
<h5 id="安裝-barman">安裝 barman</h5>
<p>barman 在18.04 中，已經被放到標準repository 中</p>
<p>所以只要直接</p>
<pre><code>sudo apt install barman
</code></pre>
<p>就可以了</p>
<h5 id="設定-barman-conf">設定 barman.conf</h5>
<p>安裝完成後，在/etc/barman.d/ 底下會有兩個範例檔案</p>
<pre><code>streaming-server.conf-template
ssh-server.conf-template
</code></pre>
<p>複製 streaming-server 檔案</p>
<pre><code>sudo cp /etc/barman.d/streaming-server.conf-template /etc/barman.d/hqs019.conf
</code></pre>
<p>內容如下</p>
<pre><code>[hqs019]
description = &quot;hqs019 &quot;
conninfo = host=192.168.11.19 user=barman dbname=database_name password=barmanpassword
streaming_conninfo = host=192.168.11.19 user=stream_barman dbname=database_name password=password
backup_method = postgres
retention_policy_mode = auto
streaming_archiver = on
slot_name = barman
</code></pre>
<p>接著修改 /etc/barman.conf</p>
<pre><code>[barman]
barman_user = barman
configuration_files_directory = /etc/barman.d
barman_home = /var/lib/barman
log_file = /var/log/barman/barman.log
log_level = DEBUG
compression = gzip
immediate_checkpoint = true
basebackup_retry_times = 3
basebackup_retry_sleep = 30
last_backup_maximum_age = 1 DAYS
</code></pre>
<p>基本上這樣就設定完成了</p>
<h5 id="檢查設定">檢查設定</h5>
<p>barman 有一些指令可以用來檢查目前的設定</p>
<p>barman show-server hqs019 可以看到所有的設定，這裡的 hqs019 跟 barman.d/hqs019.conf 裡面用&rdquo;[ ]&rdquo; 包起來的名稱要一致</p>
<pre><code>barman@barman:~$ barman show-server hqs019

</code></pre>
<p>那個backup maximum age FAILED 不用管他，因為都還沒跑過備份，這邊錯誤是正常的</p>
<p>其他都OK 的話，就可以開始備份了</p>
<p>barman backup hqs019</p>

<p>要刪除的話，要加入 backupID</p>
<pre><code>barman@ubuntu:~$ barman delete hqs019 20190822T171355

</code></pre>
<p>restore 的部份，暫時沒有測試，我想應該是要找時間測試看看怎麼還原才對</p>
<p>不過呢，前面有提到，用streaming backup ，每一次備份都是完整備份，非常的佔用空間、時間、頻寬</p>
<p>所以還是要來試試看用rsync/SSH 備份的機制</p>
