prometheus服务端-部署prometheus

 [root@prometheus-srv ~]# mkdir /apps && cd /apps/
 [root@prometheus-srv apps]# wget https://github.com/prometheus/prometheus/releases/download/v2.28.1/prometheus-2.37.9.linux-amd64.tar.gz
 [root@prometheus-srv apps]# tar xf prometheus-2.37.9.linux-amd64.tar.gz 
 [root@prometheus-srv apps]# ln -sv prometheus-2.37.9.linux-amd64 prometheus

 ​
 [Service]
 Restart=on-failure
 WorkingDirectory=/apps/prometheus/
 ExecStart=/apps/prometheus/prometheus  --config.file=/apps/prometheus/prometheus.yml
 ​
 [Install]
 WantedBy=multi-user.target
 [root@prometheus-srv apps]# systemctl enable --now prometheus.service

prometheus联邦机-部署

我演示一个机器
