1. 创建一个 $ sudo vim /etc/systemd/system/myservice.service 文件

myservice.service 替换为你要创建自启动的文件名:

内容如下:

[Unit]
Description=My Service
After=network.target

[Service]
ExecStart=/path/to/your/service
Type=simple

[Install]
WantedBy=multi-user.target

eg:我要设置trojan在开机时自启动

创建 $ sudo vim /etc/systemd/system/trojan.service 文件

[Unit]
Description=My Service Start Trojan
After=network.target

[Service]
WorkingDirectory=/home/meiyi/Downloads/trojan
ExecStart=/home/meiyi/Downloads/trojan/trojan
Type=simple

[Install]
WantedBy=multi-user.target 

 然后保存文件

2. 重新加载:

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl daemon-reload

3. 启动

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl enable trojan
Created symlink /etc/systemd/system/multi-user.target.wants/trojan.service → /etc/systemd/system/trojan.service. 

这表示trojan服务已成功启用。你看到的输出信息表明/etc/systemd/system/multi-user.target.wants/目录下创建了一个符号链接,指向/etc/systemd/system/trojan.service文件。这意味着当系统启动到multi-user.target目标时,trojan服务将会自动启动。 

手动启动:

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl start trojan

手动停止:

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl stop trojan 

重启:

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl restart trojan 

查看状态:

meiyi@meiyi-Extensa-2511G:/etc/systemd/system$ sudo systemctl status trojan

 然后就可以了。
