linux-centos开机自动执行脚本

1.检验系统是否使用rc.local

# 看有没有 rc-local.service
systemctl cat rc-local.service
# 若返回 “No files found” 说明你的发行版干脆没提供兼容单元，需要手动建

2.创建文件

touch /etc/rc.d/rc.local

3.写内容

#!/bin/bash
/usr/local/bin/test.sh
/opt/your/script2.sh
exit 0

4.添加可执行权限

chmod +x /etc/rc.d/rc.local

5.启动兼容服务

systemctl enable rc-local.service
systemctl start rc-local.service

6.验证

systemctl status rc-local.service

7.没有rc.local文件，创建rc-local.service
