centos7中啟用rc-local服務

centos7中啟用rc-local服務

 

簡介

大多時候我們可以在/etc/rc.local中寫一些命令來啟動自己的程序或服務，但是配置后無法啟動，查看了下是rc-local.service未啟動

[root@master ~]# systemctl enable rc-local.service
[root@master ~]# systemctl start rc-local.service
[root@master ~]# systemctl status rc-local.service 
● rc-local.service - /etc/rc.d/rc.local Compatibility
   Loaded: loaded (/usr/lib/systemd/system/rc-local.service; static; vendor preset: disabled)
   Active: inactive (dead)
Condition: start condition failed at Tue 2019-05-21 20:22:46 CST; 1s ago
           ConditionFileIsExecutable=/etc/rc.d/rc.local was not met

默認情況下，使用上面的命令無法啟動rc-local.service服務，原因是需要兩處文件都設置可執行權限，但是 /etc/rc.d/rc.local 默認沒有可執行權限

解決方法

## 設置可執行權限
[root@master ~]# chmod +x /etc/rc.d/rc.local
[root@master ~]# chmod +x /etc/rc.local

啟動並查看狀態

[root@master ~]# systemctl start rc-local.service 
[root@master ~]# systemctl status rc-local.service 
● rc-local.service - /etc/rc.d/rc.local Compatibility
   Loaded: loaded (/usr/lib/systemd/system/rc-local.service; static; vendor preset: disabled)
   Active: active (exited) since Tue 2019-05-21 20:23:54 CST; 1s ago
  Process: 5141 ExecStart=/etc/rc.d/rc.local start (code=exited, status=0/SUCCESS)
