  • [Unit] 段: 启动顺序与依赖关系

  • [Service] 段: 启动行为,如何启动，启动类型

  • Install] 段: 定义如何安装这个配置文件，即怎样做到开机启动

    sudo touch /etc/rc.local
    #加上权限
    sudo chmod +x /etc/rc.local
    #建立连接
    ln -s /lib/systemd/system/rc.local.service /etc/systemd/system/

    #里面放测试脚本，运行/home/script  目录下的start.sh脚本
    #!/bin/bash

    # test.sh

    cd /home/script/

    sh start.sh

    exit 0

    1. 在/home/script/的start.sh脚本中编写sh脚本即可

    2. 自启动jar包（加上环境）

      image

ubuntu20.0.4

跟上面一样，修改的是/lib/systemd/system的rc-local.service文件
