grafana docker安装

docker run -d   --name grafana   -p 3000:3000   -v grafana_data:/var/lib/grafana   grafana/grafana:latest

配置个mysql用户监控mysql的话后续要用到

CREATE USER 'exporter'@'localhost' IDENTIFIED BY 'exporter_password';
GRANT PROCESS, REPLICATION CLIENT, SELECT ON *.* TO 'exporter'@'localhost';
FLUSH PRIVILEGES;

创建mysqld-exporter 配置文件.my.cnf

[client]
user = username
password = password
host = host_ip
port = 3306

运行mysqld-exporter docker

docker run -d -p 9104:9104 \
   -v $(pwd)/.my.cnf:/etc/mysql_exporter/.my.cnf \
  prom/mysqld-exporter --config.my-cnf /etc/mysql_exporter/.my.cnf

创建并运行node-exporter 的docker,直接运行该docker会监控宿主机的相关参数

docker run -d --name node-exporter \
  -p 9100:9100 \
  --restart=unless-stopped \
  prom/node-exporter

创建prometheus.yml配置文件

global:
  scrape_interval: 15s
  evaluation_interval: 15s

alerting:
  alertmanagers:
    - static_configs:
        - targets: ['192.160.50.31:9093']

rule_files:
  - "rules/*.rules"


scrape_configs:
  - job_name: 'prometheus'  # 定义一个监控任务，名为 Prometheus
    static_configs:
      - targets: ['localhost:9090']  # 监控 Prometheus 自身
  - job_name: 'mysql_metrics'
    static_configs:
      - targets: ['192.160.50.31:9104']
  - job_name: 'node-exporter'
    static_configs:
      - targets: ['192.160.50.31:9100']

运行prometheus docker运行

docker run -d --name prometheus \
  -p 9090:9090 \
  -v  $(pwd)/prometheus.yml:/etc/prometheus/prometheus.yml \
  -v  $(pwd)/rules:/etc/prometheus/rules \
  prom/prometheus

如果配置数据源出现界面无数据，但是prometheus正常up的情况，需要创建一个新的数据源来解决这个问题。

prometheusf告警服务配置文件alertmanager.yml

global:
  resolve_timeout: 5m
