  • 配置为系统服务管理

    • 编写系统配置服务

      [root@iZj6cbgktk3zjpge312vq1Z node_exporter]# vim  /usr/lib/systemd/system/node_exporter.service
      [root@iZj6cbgktk3zjpge312vq1Z node_exporter]# cat  /usr/lib/systemd/system/node_exporter.service
      [Unit]
      Description=node_exporter
      [Service]
      # 添加认证密码文件/opt/node_exporter/config.yml ,默认可以不需要
      ExecStart=/opt/node_exporter/node_exporter --web.config=/opt/node_exporter/config.yml   
      ExecReload=/bin/kill -HUP $MAINPID
      KillMode=process
      Restart=on-failure
      [Install]
      WantedBy=multi-user.target
      
    • 添加config配置文件

      [root@VM-0-17-centos node_exporter]# yum install httpd-tools –y
      [root@VM-0-17-centos node_exporter]# htpasswd -nBC 12 '' | tr -d ':n'
      New password:       #这里输入的123456
      Re-type new password:    #这里输入的123456
      $2y$12$.YGKNPkYfSOsm.JataWRUe4vWdTS8nW6YtPQI0Jr14eTv6E5Fpdga          # 这段是生成的key
      
    • 编写启动配置文件

      [root@iZj6cbgktk3zjpge312vq1Z node_exporter]# vim config.yml
      [root@iZj6cbgktk3zjpge312vq1Z node_exporter]# cat config.yml
      basic_auth_users:
        prometheus: $2y$12$.YGKNPkYfSOsm.JataWRUe4vWdTS8nW6YtPQI0Jr14eTv6E5Fpdga
      
    • 启动服务

      systemctl daemon-reload
      systemctl start node_exporter
      systemctl enable node_exporter
      
  • 在prometheus添加主机

    • 添加配置文件

      [root@iZj6cbgktk3zjpge312vq2Z prometheus]# vim prometheus.yml
      [root@iZj6cbgktk3zjpge312vq2Z prometheus]# cat prometheus.yml

        evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
        # scrape_timeout is set to the global default (10s).

        # - "second_rules.yml"
      
      # A scrape configuration containing exactly one endpoint to scrape:
      # Here it's Prometheus itself.
      scrape_configs:
        # The job name is added as a label job=<job_name> to any timeseries scraped from this config.
        - job_name: 'prometheus'
      
          # metrics_path defaults to '/metrics'
          # scheme defaults to 'http'.
      
          static_configs:
          - targets: ['127.0.0.1:9090']
        - job_name: linux
          # 添加监控主机的用户和密码
          basic_auth:
            username: prometheus
            password: 123456
          static_configs:

              labels:
                prod: web
      
      
    • 重启服务

      [root@iZj6cbgktk3zjpge312vq2Z prometheus]# /bin/systemctl restart prometheus
