docker-compose搭建mongodb分片集群及安全身份认证（实战）

冷不防 2023-06-25 04:41 45阅读 0赞

最近由于项目中设计中有使用mongodb，具体mongodb的优点我就不多说。这篇文章主要是分享下我通过docker-compose搭建mongodb分片集群，并实现安全身份认证访问(mongodb安装后默认是不需要用户名和密码访问的)。

下面是我配置的docker-compose.yml文件：

version: '2'
    services:
      shard_server01:
        container_name: shard_server01
        image: mongo:3.6
        networks:
          mongo:
            ipv4_address: 192.168.1.11
        ports:
          - 27018:27018
        volumes:
          - /data/docker/mongos/data/shard_server01/data/db:/data/db
          - /data/docker/mongos/data/shard_server01/data/configdb:/data/configdb
          - /data/docker/mongos/data/shard_server01/data/backup:/data/backup
          - /data/docker/mongos/data/mongod.conf:/etc/mongod.conf
          - /data/docker/mongos/data/key.file:/etc/key.file
        command: --shardsvr --bind_ip_all
        restart: always
        depends_on:
          - rs_config_server01
          - rs_config_server02
        ulimits:
          nofile:
            soft: 300000
            hard: 300000
      shard_server02:
        container_name: shard_server02
        image: mongo:3.6
        networks:
          mongo:
            ipv4_address: 192.168.1.12
        ports:
          - 27028:27018
        volumes:
          - /data/docker/mongos/data/shard_server02/data/db:/data/db
          - /data/docker/mongos/data/shard_server02/data/configdb:/data/configdb

          - /data/docker/mongos/data/mongod.conf:/etc/mongod.conf
          - /data/docker/mongos/data/key.file:/etc/key.file
        command: --shardsvr --keyFile "/etc/key.file" --bind_ip_all --auth
        restart: always
        depends_on:
          - rs_config_server01
          - rs_config_server02
    # 配置服务器集群两个节点（mongodb3.4之后的版本需要两个config_server）
      rs_config_server01:
        container_name: rs_config_server01
        image: mongo:3.6
        networks:
          mongo:
            ipv4_address: 192.168.1.13
        ports:
          - 27019:27019
        volumes:
          - /data/docker/mongos/data/rs_config_server01/data/db:/data/db

          - /data/docker/mongos/data/mongod.conf:/etc/mongod.conf
          - /data/docker/mongos/data/key.file:/etc/key.file
        command: --configsvr --replSet "rs_config_server" --bind_ip_all
        restart: always
    
      rs_config_server02:
        container_name: rs_config_server02
        image: mongo:3.6
        networks:
          mongo:
            ipv4_address: 192.168.1.14
        ports:
          - 27029:27019
        volumes:
          - /data/docker/mongos/data/rs_config_server02/data/db:/data/db

          - /data/docker/mongos/data/key.file:/etc/key.file
        command: --configsvr --replSet "rs_config_server" --bind_ip_all
        restart: always
    
        
    
    # 路由节点mongos
      mongos:
        container_name: mongos
        networks:
          mongo:
            ipv4_address: 192.168.1.15
        image: mongo:3.6
        ports:
          - 27017:27017
        volumes:
          - /data/docker/mongos/data/data/db:/data/db
          - /data/docker/mongos/data/data/configdb:/data/configdb
          - /data/docker/mongos/data/data/backup:/data/backup
          - /data/docker/mongos/data/mongod.conf:/etc/mongod.conf
          - /data/docker/mongos/data/key.file:/etc/key.file
        entrypoint: mongos
        command: --configdb rs_config_server/192.168.1.13:27019,192.168.1.14:27019 --bind_ip_all
        depends_on:
          - shard_server01
          - shard_server02
    
    networks:
        mongo:
            driver: bridge
            ipam:
                config:
                    - subnet: 192.168.1.10/24

注意：目前是没有增加安全身份认证的。

### 使用docker-compose启动mongo集群 ###

docker-compose up -d

### 配置服务器设置（config\_server） ###

docker exec -it rs_config_server01 /bin/bash
    mongo --host localhost --port 27019

rs.initiate({
        _id: "rs_config_server",
        configsvr: true,
        members: [
            { _id : 0, host : "192.168.1.13:27019" },
            { _id : 1, host : "192.168.1.14:27019" }
        ]
    });

### 配置路由mongos服务 ###

docker exec -it mongos /bin/bash
    mongo --port 27017

将分片集群添加到mongos中

sh.addShard("192.168.1.11:27018")
    sh.addShard("192.168.1.12:27018")

到目前为止，mongodb分片集群已经搭建完毕。但是mongdb默认是无需账户即可直接访问。故，若是需要增加账号和密码，并强制需要输入正确的账户和密码才能登陆的话，看下文。

**1、创建mongdb的账户和密码**

进入mongos路由服务

docker exec -it mongos /bin/bash
    mongo --port 27017

切换到admin库，创建用户root

use admin
    
    db.createUser(
    		    {
    		        user:"root",
    		        pwd:"123456",
    		        roles:[{role:"root",db:"admin"}]
    		    }
    		)

**2、生成mongo节点之前通讯认证文件（key.file）**

openssl rand -base64 741 > key.file
    chmod 600 key.file
    chown 999 key.file

**3、将key.file挂载docker容器里面，启动命令指定key.file，并增加需要认证(--auth)**

增加安全认证之后的docker-compose .yml文件如下

version: '2'
    services:
      shard_server01:
        container_name: shard_server01
        image: mongo:3.6

        command: --shardsvr --keyFile "/etc/key.file" --bind_ip_all --auth
        restart: always

      rs_config_server02:
        container_name: rs_config_server02

          - shard_server02
    
    networks:
        mongo:
            driver: bridge
            ipam:
                config:
                    - subnet: 192.168.1.10/24

**4、重启docker-compose**

docker-compose down
    docker-compose up -d

到此，增加安全登录已经配置完毕。若不使用账号和密码访问结果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l1ZmVpX2phdmE_size_16_color_FFFFFF_t_70][]

使用账号和密码访问结果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l1ZmVpX2phdmE_size_16_color_FFFFFF_t_70 1][]

总结：搭建整个mongodb集群花费时间还是比较大的，这里总结一下，希望能对大家有帮助。有疑问欢迎留言。若是帮助到您了，别忘记点个赞哈哈~
