<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>之前在LAN/windows環境下一直都是用ultravnc/winvnc/tigervnc之類的VNC軟體</p>
<p>但是如果要過 internet 就會碰到各種開port的問題</p>
<p>在這種環境下,就有了當時 teamviewer 的橫空出世</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>只要下載teamviewer被控端開啟後報ID 給協助者就好了</p>

<p>前幾天接的一個case</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>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>一樣成本考量就不用INTEL 了,買了這張 ASUS 10G 網卡</p>

<p>最近因為一直碰到硬碟故障的問題算起來那一批同時購買的5X顆 seagate 2T硬碟已經有一半以上故障返修了&hellip;.</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>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>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>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>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>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>
