ansible 自动化批量部署Prometheus node_exporter

ansible 部署Prometheus node_exporter

1.编写site.yaml文件

• 创建工作目录

 mkdir -p /opt/node-export
cd /opt/node-export

• 配置site.yaml
  配置如下：

- hosts: all
  tasks: 
    - name: copy node_exporter
      copy:
        src: files/node_exporter
        dest: /usr/local/bin/
        owner: root
        group: root
        mode: 755
      notify:
        - call restart service
    - name: copy node-exporter
      copy:
        src: files/node-exporter
        dest: /etc/sysconfig/
      notify:
        - call restart service
    - name: copy node_exporter.service
      copy:
        src: files/node-exporter.service
        dest: /etc/systemd/system/ 
      notify:
        - call restart service
    - name: start node_exporter.service
      service:
        name: node-exporter.service
        state: started
        daemon_reload: yes
        enabled: yes
  handlers:
    - name: call restart service
      systemd:
        state: restarted
        daemon_reload: yes
        name: node-exporter.service

2.node_exporter二进制文件

• 创建目录

mkdir files

说明:files文件里面包含node_exporter二进制文件；开机自启文件node-exporter.service；node_exporter开机自启服务自定义端口配置node-exporter

• systemd开机自启配置 node-exporter.service

[Unit]
Description=Node Exporter
 
[Service]
User=root
EnvironmentFile=/etc/sysconfig/node-exporter
ExecStart=/usr/local/bin/node_exporter $OPTIONS

  
[Install]
WantedBy=default.target

• 编辑node-exporter自定义端口配置

vim node-exporter

OPTIONS = "--web.listen-address=":9100""
