+## systemd 服务
+用 `cargo install bore-cli` 安装后执行 `sudo ln -s ~/.cargo/bin/bore /usr/bin` 创建软连接。
+
+然后在 `/etc/systemd/system` 目录下新建 `bore.service`，添加以下内容
+```
+[Unit]
+Description=bore service
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+ExecStart=bore server
+Restart=always
+RestartSec=60s
+User=root
+
+[Install]
+WantedBy=default.target
+```
+接着执行 `sudo systemctl enable bore.service` 即可开机自启。
+用 `sudo systemctl start bore.service` 来启动服务。
+用 `sudo systemctl status bore.service` 查看状态。
+这些都是 `systemd` 的基操了，不多赘述。
+成功的话状态会输出以下信息
+```
+$ sudo systemctl status bore.service
+● bore.service - bore service
