centos7中启用rc-local服务
简介
大多时候我们可以在/etc/rc.local中写一些命令来启动自己的程序或服务，但是配置后无法启动，查看了下是rc-local.service未启动
[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
默认情况下，使用上面的命令无法启动rc-local.service服务，原因是需要两处文件都设置可执行权限，但是 /etc/rc.d/rc.local 默认没有可执行权限
解决方法
## 设置可执行权限 [root@master ~]# chmod +x /etc/rc.d/rc.local [root@master ~]# chmod +x /etc/rc.local
启动并查看状态
[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) May 21 20:23:54 master systemd[1]: Starting /etc/rc.d/rc.local Compatibility... May 21 20:23:54 master systemd[1]: Started /etc/rc.d/rc.local Compatibility.
