linux 开机自启 rc.local

rc.local 是启动加载文件

例1. compose启动Harbor

• 写一个开启自动启动的脚本

  [root@harbor harbor]# vim startall.sh  
  #!/bin/bash 
  cd /root/harbor
  docker-compose stop && docker-compose start
  

• 给脚本权限

  chmod +x startall.sh
  chmod +x /etc/rc.d/rc.local		#ll 查看rc.local有没有权限，默认没有，需要添加
  

• 在rc.local文件末尾添加需要执行的脚本的绝对路径

  [root@k8s-master harbor]# vim /etc/rc.d/rc.local 
  #!/bin/bash
  # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
  #
  # It is highly advisable to create own systemd services or udev rules
  # to run scripts during boot instead of using this file.
  #
  # In contrast to previous versions due to parallel execution during boot
  # this script will NOT be run after all other services.
  #
  # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
  # that this script will be executed during boot.
  
  touch /var/lock/subsys/local
  /bin/bash /root/harbor/startall.sh
