prometheus之node_exporter部署

1. 下载压缩包并解压

   mkdir /opt/node_exporter/
   cd /opt/node_exporter/
   wget https://github.com/prometheus/node_exporter/releases/download/v1.5.0/node_exporter-1.5.0.linux-amd64.tar.gz
   tar -zxvf node_exporter-1.5.0.linux-amd64.tar.gz
   ln -s /opt/node_exporter/node_exporter-1.5.0.linux-amd64/node_exporter /usr/bin/
   
   

2. 编写service文件

   vim /etc/systemd/system/node_exporter.service
   

   [Service]
   ExecStart=/usr/bin/node_exporter --web.listen-address=:9101 #指定监听端口
   [Install]
   WantedBy=multi-user.target
   [Unit]
   Description=node_exporter
   After=network.target
   

3. 设置开机自启并启动服务

   systemctl  daemon-reload
   systemctl enable node_exporter
   systemctl start node_exporter
   

4. 防火墙放行端口

   firewall-cmd --permanent --add-port=9101/tcp --zone=public
   firewall-cmd --reload
   

5. 访问url检测是否获取数据

   http://主机ip:9101/metrics
