====== Linux添加开机自启动服务 ======
1.创建服务文件yourService.service，ExecStart为自己的程序绝对路径
    [Unit]
    Description=Hello Service
    [Service]
    Type=simple
    ExecStart=/usr/bin/hello.sh
    SuccessExitStatus=2
    [Install]
    WantedBy=multi-user.target

2.复制yourService.service到/lib/systemd/system/目录

3.重载服务项目<code>systemctl daemon-reload</code>

4.开机自启动设置<code>systemctl enable yourService.service</code>

5.启动服务<code>service yourService start</code>
