使用Systemd实现开机运行命令

编写脚本

编写一个脚本mount-sda6.service，放在/etc/systemd/system/下

[Unit]
Description=mount sda6 for backup

[Service]
ExecStart=/bin/bash -c "mount -o compress=zstd /dev/sda6 /media/backup"

[Install]
WantedBy=multi-user.target

如果ExecStart中运行了某个脚本，记得要赋于脚本运行权限(chmod +x)。

查看当前的状态

使用systemctl list-unit-files --type=service命令。

sudo systemctl list-unit-files --type=service|grep mount-sda6

出现如下内容即为正常。

mount-sda6.service                         disabled

enable服务后使之start

加入开机自启动

sudo systemctl enable mount-sda6

马上运行该服务

sudo systemctl start mount-sda6

查看运行状态

sudo systemctl status mount-sda6

显示如下：

   Loaded: loaded (/etc/systemd/system/mount-sda6.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Fri 2019-12-13 22:11:32 CST; 12h ago
 Main PID: 939 (code=exited, status=0/SUCCESS)

12月 13 22:11:32 ki-PC systemd[1]: Started mount sda6 for backup.

重启，查看服务是否正常自动启动

sudo reboot
