Linux实现开机后，自动执行某条命令/重启某个服务【测试成功】

一、需求背景

    存在某台服务器，设置某服务开机自启后无法生效，故需要在开机后手动执行命令启动，操作比较繁琐，采用自动化脚本方式实现。

二、编写系统启动单元

vim /etc/systemd/system/restart-yl.service

    [Unit]Description=YLAfter=network.target
    [Service]ExecStart=/bin/systemctl restart YL.serviceType=oneshotRemainAfterExit=yes
    [Install]WantedBy=multi-user.target

    保存文件并退出文本编辑器。

    三、重载并使其生效

    重新加载systemd配置以使其了解新服务：

        systemctl daemon-reload

    启用该服务以在启动时运行：

        systemctl enable restart-yl.service

      [root@localhost ~]# systemctl enable restart-ylmonitor.serviceCreated symlink /etc/systemd/system/multi-user.target.wants/restart-ylmonitor.service → /etc/systemd/system/restart-ylmonitor.service.
        [root@localhost ~]# systemctl status restart-ylmonitor.service● restart-ylmonitor.service - YLMonitor Loaded: loaded (/etc/systemd/system/restart-ylmonitor.service; enabled; vendor preset: disable> Active: inactive (dead)[root@localhost ~]# systemctl start restart-ylmonitor.service[root@localhost ~]# systemctl status restart-ylmonitor.service● restart-ylmonitor.service - YLMonitor Loaded: loaded (/etc/systemd/system/restart-ylmonitor.service; enabled; vendor preset: disable> Active: active (exited) since Mon 2023-09-11 10:43:31 CST; 2s ago Process: 3276910 ExecStart=/bin/systemctl restart YLMonitor.service (code=exited, status=0/SUCC> Main PID: 3276910 (code=exited, status=0/SUCCESS)
