使用Docker-Compose安装MongoDB

安装Docker-Compose

Compose 安装

Linux 上我们可以从 Github 上下载它的二进制包来使用，最新发行的版本地址：https://github.com/docker/compose/releases。

运行以下命令以下载 Docker Compose 的当前稳定版本：

$ sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

要安装其他版本的 Compose，请替换 v2.2.2。

Docker Compose 存放在 GitHub，不太稳定。

你可以也通过执行下面的命令，高速安装 Docker Compose。

curl -L https://get.daocloud.io/docker/compose/releases/download/v2.4.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

将可执行权限应用于二进制文件：

$ sudo chmod +x /usr/local/bin/docker-compose

创建软链：

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

测试是否安装成功：

$ docker-compose version
cker-compose version 1.24.1, build 4667896b

配置MongoDB的目录和文件。

新建MongoDB目录,子目录database和docker-compose.yml.

docker-compose.yml内容如下：

version: "3"
services:
  mongodb:
    image: mongo
    container_name: mongodb
    restart: always
    ports:
      - 27017:27017
    volumes:
      - ./data:/data/db
    command: --wiredTigerCacheSizeGB 4 --auth # 限制内存大小, 需要认证
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=admin
  mongo-express:
    image: mongo-express
    container_name: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin
      - ME_CONFIG_MONGODB_ADMINPASSWORD=admin
      - ME_CONFIG_MONGODB_SERVER=mongodb

networks:
  default:
    name: mongodb_network

启动docker-compose，运行MongoDB

[root@instance-1 MongoDB]# docker-compose up -d
Creating network "mongodb_network" with the default driver
Creating mongodb       ... done
Creating mongo-express ... done

进入MongoDB容器, 进入MongoDB shell

docker exec -it mongodb bash
mongo mongodb://localhost:27017 -u admin -p admin

然后查看数据库

> show dbs;
admin   0.000GB
config  0.000GB
local   0.000GB

切换到admin的数据库，新建用户

> use admin
switched to db admin
> db.createUser({user:"root",pwd:"root",roles:[{role:'root',db:'admin'}]})
Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}
>

关闭数据库

[root@instance-1 MongoDB]# docker-compose down
Stopping mongo-express ... done
Stopping mongodb       ... done
Removing mongo-express ... done
Removing mongodb       ... done
Removing network mongodb_network
