  • 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
# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "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:
      - targets: ['10.1.2.211:9100']
        labels:
          prod: web
