# centos7 prometheus添加node\_exporter节点 #

在iZbp13nwyvib50dibue9opZ这台上安装node\_exporter

NODE_PATH='/data/prometheus/node_exporter/'
    cd /usr/local/src/
    mkdir -p ${NODE_PATH}
    # wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz 
    cp -r /opt/node_exporter-0.18.1.linux-amd64.tar.gz ./
    tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz
    cp node_exporter-0.18.1.linux-amd64/node_exporter ${NODE_PATH}
    useradd -s /sbin/nologin -M prometheus
    chown -R prometheus.prometheus ${NODE_PATH}

安装系统服务

cat > /lib/systemd/system/node_exporter.service <<EOF [Unit] Description=node_exporter Documentation=https://prometheus.io/ After=network.target [Service] Type=simple User=prometheus ExecStart=/data/prometheus/node_exporter/node_exporter Restart=on-failure [Install] WantedBy=multi-user.target EOF
    
    systemctl daemon-reload
    systemctl enable node_exporter.service
    systemctl start node_exporter.service
    systemctl status node_exporter.service
    
    netstat -plntu |grep 9100

修改prometheus.yml 如下

global:
    alerting:
      alertmanagers:
      - static_configs:
        - targets:
    rule_files:
    scrape_configs:
      - job_name: 'prometheus'
        static_configs:
        - targets: ['localhost:9090']
      - job_name: 'node_exporter'
        static_configs:
          - targets: ['localhost:9100']
      - job_name: linux1
        static_configs:
          - targets: ['192.168.0.33:9100']
            labels:
              instance: sys1
      - job_name: linux2
        static_configs:
          - targets: ['localhost:9100']
            labels:
              instance: sys2

重启一下prometheus

systemctl restart prometheus

job\_name对应JOB

加入成功之后 如下
