PMM 容器环境搭建

参考: 容器快速部署 PMM 添加 MongoDB 监控

启动 PMM 容器以及 MongoDB容器

1. 创建一个 docker-compose 项目，并进入

mkdir pmm-server
cd pmm-server

2. 创建 compose.yaml 文件，填入以下内容

version: "3"
 
services:
  mongodb:
    hostname: mongodb
    image: 'mongo:6'
    environment:
      - 'MONGO_INITDB_DATABASE=pmm'
      - 'MONGO_INITDB_ROOT_USERNAME=admin'
      - 'MONGO_INITDB_ROOT_PASSWORD=admin'
    ports:
      - "27017:27017"
    command: [ "mongod", "--profile", "2", "--slowms", "200"]
 
  pmm-server:
    hostname: pmm-server
    image: "percona/pmm-server:2"
    ports:
      - "443:443"
    restart: always

3. 启动容器

docker compose up

初始化容器设置

1. 设置 pmm 管理员密码

docker exec -t pmm-server-pmm-server-1 change-admin-password admin

2. 使用 mongosh 连接到 mongodb

docker exec -it pmm-server-mongodb-1 /bin/mongosh --port 27017 --host localhost

3. 在 mongodb 上创建一个用于 pmm 监控的用户

use admin
 
db.auth("admin", "admin")
 
db.getSiblingDB("admin").createRole({
    role: "explainRole",
    privileges: [
        {
            resource: {
                db: "",
                collection: ""
            },
            actions: [
                "listIndexes",
                "listCollections",
                "dbStats",
                "dbHash",
                "collStats",
                "find"
            ]
        },
        {
            resource: {
                db: "",
                collection: "system.profile"
            },
            actions: [
                "collStats",
                "dbStats",
                "indexStats"
            ]
        }
    ],
    roles: []
})
 
db.getSiblingDB("admin").createRole({
    "role": "pbmAnyAction",
    "privileges": [{
        "resource": {
            "anyResource": true
        },
        "actions": [
            "anyAction"
        ]
    }],
    "roles": []
})
 
db.getSiblingDB("admin").createUser({
    user: "pmm",
    pwd: "pmm",
    roles: [
        { role: "explainRole", db: "admin" },
        { role: "clusterMonitor", db: "admin" },
        { role: "read", db: "local" },
        { "db": "admin", "role": "readWrite", "collection": "" },
        { "db": "admin", "role": "backup" },
        { "db": "admin", "role": "clusterMonitor" },
        { "db": "admin", "role": "restore" },
        { "db": "admin", "role": "pbmAnyAction" }
    ]
})

PMM 添加 MongoDB 监控

1. 添加监控

docker exec -t pmm-server-pmm-server-1 pmm-admin --server-url=https://admin:admin@pmm-server --server-insecure-tls add mongodb --username=pmm --password=pmm --enable-all-collectors mongodb_srv_1 mongodb:27017

2. 访问 https://localhost:443 webUI，登录 pmm，username=admin,password=admin
