简介

大多时候我们可以在/etc/rc.d/rc.local中写一些命令来实现随着服务器的启动(重启)运行自己的程序或服务，但是配置后无法启动，查看了下rc-local.service服务状态显示未启动。

[root@master ~]# systemctl status rc-local
● rc-local.service - /etc/rc.d/rc.local CompatibilityLoaded: loaded (/usr/lib/systemd/system/rc-local.service; static; vendor preset: disabled)Active: inactive (dead)
Condition: start condition failed at 五 2024-03-15 15:40:37 CST; 2s agoConditionFileIsExecutable=/etc/rc.d/rc.local was not met

问题分析

默认情况下，使用下面的命令无法启动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。

[root@master ~]# systemctl start rc-local.service
[root@master ~]# systemctl enable rc-local.service
[root@master ~]# cd /etc/rc.d/
[root@master rc.d]# ll

解决方法

设置可执行权限

# 设置可执行权限
[root@master rc.d]# chmod +x /etc/rc.d/rc.local

启动并查看状态

[root@master etc]# systemctl start rc-local.service
[root@master etc]# systemctl status rc-local.service
