   prometheus官网下载地址：Download | Prometheus

   #下载截止2021/9/9最新版本
   wget https://github.com/prometheus/prometheus/releases/download/v2.29.2/prometheus-2.29.2.linux-amd64.tar.gz
   
   #创建prometheus目录
   mkdir -p /opt/monitor
   
   #解压移动
   tar -xf prometheus-2.29.2.linux-amd64.tar.gz
   mv prometheus-2.29.2.linux-amd64 /opt/monitor/prometheus
   
   #添加systemctl管理
   vi /usr/lib/systemd/system/prometheus.service
   [Unit]
   Description=prometheus
   [Service]
   ExecStart=/opt/monitor/prometheus/prometheus --config.file=/opt/monitor/prometheus/prometheus.yml
   ExecReload=/bin/kill -HUP $MAINPID
   KillMode=process
   Restart=on-failure
   [Install]
   WantedBy=multi-user.target
   
   #启动prometheus
   systemctl daemon-reload 
   systemctl start prometheus.service 
   systemctl status prometheus.service
   

2. granfana搭建

   #下载截止2021/9/9最新版本
   wget https://dl.grafana.com/enterprise/release/grafana-enterprise-8.1.2.linux-amd64.tar.gz
   tar -zxvf grafana-enterprise-8.1.2.linux-amd64.tar.gz
   mkdir /opt/monitor/grafana
   mv grafana-8.1.2 /opt/monitor/grafana
   
   vi /usr/lib/systemd/system/grafana.service
   [Unit]
   Description=grafana
   [Service]
   ExecStart=/opt/monitor/grafana/bin/grafana-server -homepath=/opt/monitor/grafana
   ExecReload=/bin/kill -HUP $MAINPID
   KillMode=process
   Restart=on-failure
   [Install]
   WantedBy=multi-user.target
   
   systemctl daemon-reload 
   systemctl start grafana.service
   systemctl status grafana.service 
   

3. node_exporter：用于监控Linux系统的指标采集器

   prometheus采集器地址：Exporters and integrations | Prometheus

   #注：如果github拉取较慢，可采用迅雷下载上传
   wget https://github.com/prometheus/node_exporter/releases/download/v1.2.2/node_exporter-1.2.2.linux-amd64.tar.gz
   
   tar  -xf node_exporter-1.2.2.linux-amd64.tar.gz 
   mv node_exporter-1.2.2.linux-amd64 /usr/local/node_exporter
   
   vi /usr/lib/systemd/system/node_exporter.service
   [Unit]
   Description=node_exporter
   [Service]
   ExecStart=/usr/local/node_exporter/node_exporter
   #ExecStart=/usr/local/node_exporter/node_exporter --web.config=/usr/local/node_exporter/config.yml
   ExecReload=/bin/kill -HUP $MAINPID
   KillMode=process
   Restart=on-failure
   [Install]
   WantedBy=multi-user.target
   
   systemctl daemon-reload 
   systemctl start node_exporter.service 
   systemctl status node_exporter.service 
   

4. 配置prometheus进行发现

   #末尾添加配置，ip地址为安装node_exporter的地址
   vim /opt/monitor/prometheus/prometheus.yml
   - job_name: "node"
       static_configs:
         - targets: ["192.168.123.97:9100"]
   #prometheus支持热加载配置文件
   kill -HUP prometheus的PID
   

5. 访问prometheus的ip:9090查看

   点击Status ----> Targets 查看

   

6. 登陆granfana页面ip:3000

   默认密码admin admin 初次登陆需要修改密码

   点击左侧设置 ----> Data sources

   

   最下方测试保存

7. 添加监控模板

   

   点击import完成后，填入9276 点击load

   然后在import上边选择 之前添加的数据库后 再点击import

8. 效果如图
