mongo微服务搭建

(1)写了个yaml配置文件，可以再根据mongo参数增添，我的都没配置什么。

 [root@dev01 mongo]# cat mongo_cluster.yaml

    container_name: node1

  mongos1:
    container_name: mongos1
    networks:
      mongo:
        ipv4_address: 172.20.0.17
    image: mongo
    ports:
      - 27017:27017
    volumes:

      - ./mongos1/data/configdb:/data/configdb
    entrypoint: mongos
    command: --configdb config_server/172.20.0.14:27019,172.20.0.15:27019,172.20.0.16:27019 --bind_ip_all
    depends_on:
      - node1
      - node2
      - node3
  mongos2:
    container_name: mongos2
    networks:
      mongo:
        ipv4_address: 172.20.0.18
    image: mongo
    ports:

    volumes:
      - ./mongos2/data/db:/data/db
      - ./mongos2/data/configdb:/data/configdb
    entrypoint: mongos
    command: --configdb config_server/172.20.0.14:27019,172.20.0.15:27019,172.20.0.16:27019 --bind_ip_all
    depends_on:
      - node1
      - node2
      - node3
  mongos3:
    container_name: mongos3
    networks:
      mongo:
        ipv4_address: 172.20.0.19
    image: mongo
    ports:

    depends_on:
      - node1
      - node2
      - node3
networks:
  mongo:
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.10/24

(2)本地新建映射目录：

mkdir -p ./{node1,node2,node3,mongos1,mongos2,mongos3,config1,config2,config3}/data

(3)检测下洗的yaml有没有问题

 [root@dev01 mongo]# docker-compose -f mongo_cluster.yaml config 

没问题会提示。

(4)直接拉起mongo服务：

  docker-compose -f mongo_cluster.yaml up -d 

(5)config server配置：

## 登录config
mongo --port 27019 --host 172.20.0.14
​
## 创建配置（_id : "config" 等于上边的 replSetName: config）
config = {
    _id: "config_server",
    configsvr: true,
    members : [
        {_id: 0, host: "172.20.0.14:27019"},
        {_id: 1, host: "172.20.0.15:27019"},
        {_id: 2, host: "172.20.0.16:27019"}
    ]
};
​
## 初始化副本集配置
rs.initiate(config)
​
## 查看状态
rs.status()

（6）mongo配置：

## 登录mongos
mongo --port 27017 --host 172.20.0.17
## 添加分片
sh.addShard("172.20.0.11:27018")
sh.addShard("172.20.0.12:27018")
sh.addShard("172.20.0.13:27018")

然后可以通过27017,27027,27037任意一个本地端口进行连接测试,可以研究mongo rs集群了。
