参考查看链接 prometheus-basic_auth加密配置

prometheus

prometheus.yml

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: ["localhost:9090"]
    basic_auth:
      username: 1111  
      password: 1111
      
  - job_name: node

    static_configs:
        - targets: ['111:9100']
        - targets: ['111:9100']
    basic_auth:
      username: 1111   
      password: 1111

添加一个config.yml文件，用参考教程里的生成一个长密码

basic_auth_users:
  # 当前设置的用户名为admin， 可以设置多个
  adminadmin: $2y$12$9iHkTLGS$2y$12$9iHkTLGS$2y$12$9iHkTLGS$2y$12$9iHkTLGS

启动命令变成 /opt/prometheus/prometheus-2.39.1.linux-amd64/prometheus --config.file=/opt/prometheus/prometheus-2.39.1.linux-amd64/prometheus.yml --web.config.file=/opt/prometheus/prometheus-2.39.1.linux-amd64/config.yml

node-exporter

node-exporter也是一样的步骤，复制config.yml，启动的时候加上--web.config什么什么的就行了 such as
/opt/node-exporter/node_exporter --web.config=/opt/node-exporter/config.yml

记得最后改prometheus里面的 prometheus.yml 两个都要加上basic auth
