## systemctl
创建 `/etc/systemd/system/prometheus.service`文件，复制下面的内容进去。
```shell
[Unit]
Description=Prometheus Monitoring System
Documentation=https://prometheus.io/docs/introduction/overview/
After=network.target[Service]
User=prometheus
Group=prometheus
Type=simple
ExecStart=/usr/local/prometheus/prometheus
–config.file=/usr/local/prometheus/prometheus.yml
–storage.tsdb.path=/usr/local/prometheus/data
–web.enable-lifecycle
–web.listen-address=0.0.0.0:9090
Restart=always
[Install] WantedBy=multi-user.target
* `--web.enable-lifecycle` : 启用热加载，不用`restart `进程就可以重载配置。
## 启动并设置为开机自启
然后执行下述命令，启动`prometheus server`。
```shell
[root@prometheus software]# systemctl daemon-reload
[root@prometheus software]# systemctl enable prometheus
[root@prometheus software]# systemctl start prometheus
[root@prometheus software]# systemctl status prometheus
[root@prometheus prometheus]# systemctl status prometheus
