步骤

  1. 将rc-local.service文件复制到 /etc/systemd/system/ 目录下

    cp ./rc-local.service /etc/systemd/system/

    ubuntu22.04中 /etc/目录下是没有 rc.local 文件的，需要手动创建

    1
    2
    touch /etc/rc.local
    chmod 755 /etc/rc.local

  3. 设置开机启动 rc-local

    1
    2
    3
    systemctl start rc-local
    systemctl enable rc-local
    reboot

  4. 查看服务已经正常开启

    1
    systemctl status rc-local

  5. 在 rc.local 中添加需要自动执行的脚本

    /home/application/dh/server/manage_dh.sh start
