ubuntu 18.04 預設移掉了 /etc/rc.local 的功能
|
|
|
|
|
|
變成要用 systemd 的方式來運作，可是有點難用…
|
|
|
|
|
|
紀錄一下步驟，再來研究怎麼整合到 preseed 裡面
|
|
|
|

|
|
|
|
### 1. 建立 rc-local.service
|
|
|
|
|
|
#### sudo vi /etc/systemd/system/rc-local.service
|
|
|
```
|
|
|
[Unit]
|
|
|
Description=/etc/rc.local Compatibility
|
|
|
ConditionPathExists=/etc/rc.local
|
|
|
|
|
|
[Service]
|
|
|
Type=forking
|
|
|
ExecStart=/etc/rc.local start
|
|
|
TimeoutSec=0
|
|
|
StandardOutput=tty
|
|
|
RemainAfterExit=yes
|
|
|
SysVStartPriority=99
|
|
|
|
|
|
[Install]
|
|
|
WantedBy=multi-user.target
|
|
|
```
|
|
|
|
|
|
### 2. 建立 rc.local.bak
|
|
|
|
|
|
這個檔案的作用是，我只需要client在PXE 裝完系統後的第一次開機會發通知信件
|
|
|
|
|
|
所以如果一直保留著 /etc/rc.local 的變動，就變成每次開機都會送出信件
|
|
|
|
|
|
因此，需要先保留原本的 rc.local
|
|
|
|
|
|
在送出通知信件之後，就用原來的 rc.local 蓋掉修改過的 rc.local
|
|
|
|
|
|
#### sudo vi /etc/rc.local.bak
|
|
|
|
|
|
```
|
|
|
#!/bin/sh -e
|
|
|
#
|
|
|
# rc.local
|
|
|
#
|
|
|
# This script is executed at the end of each multiuser runlevel.
|
|
|
# Make sure that the script will "exit 0" on success or any other
|
|
|
# value on error.
|
|
|
#
|
|
|
# In order to enable or disable this script just change the execution
|
|
|
# bits.
|
|
|
#
|
|
|
# By default this script does nothing.
|
|
|
|
|
|
|
|
|
exit 0
|
|
|
```
|
|
|
|
|
|
### 3. 建立 rc.local
|
|
|
|
|
|
#### sudo vi /etc/rc.local
|
|
|
|
|
|
|
|
|
```
|
|
|
#!/bin/sh -e
|
|
|
#
|
|
|
# rc.local
|
|
|
#
|
|
|
# This script is executed at the end of each multiuser runlevel.
|
|
|
# Make sure that the script will "exit 0" on success or any other
|
|
|
# value on error.
|
|
|
#
|
|
|
# In order to enable or disable this script just change the execution
|
|
|
# bits.
|
|
|
#
|
|
|
# By default this script does nothing.
|
|
|
|
|
|
hostname|mail -s pxe_install_complete changch@abc.com
|
|
|
cp /etc/rc.local.bak /etc/rc.local
|
|
|
|
|
|
exit 0
|
|
|
```
|
|
|
|
|
|
### 4. 修改 rc.local permission
|
|
|
|
|
|
```
|
|
|
sudo chmod +x /etc/rc.local
|
|
|
```
|
|
|
|
|
|
### 5. 啟用 rc-local service
|
|
|
|
|
|
```
|
|
|
sudo systemctl enable rc-local
|
|
|
```
