14.12.1. 使用mongoose访问mongodb

14.12.1.1. docker运行mongodb

在项目目录中创建docker-compose.yaml文件，内容如下：

version: '3.1'

services:

mongo:
    image: mongo
    restart: always
    ports:
    - 27017:27017
    environment:
    MONGO_INITDB_ROOT_USERNAME: root
    MONGO_INITDB_ROOT_PASSWORD: example

mongo-express:
    image: mongo-express
    restart: always
    ports:
    - 8081:8081
    environment:
    ME_CONFIG_MONGODB_ADMINUSERNAME: root
    ME_CONFIG_MONGODB_ADMINPASSWORD: example
    ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/

注意

端口别和宿主机上的端口冲突了。

启动

docker compose up

14.12.1.2. 连接mongo，并创建账号

mongo -u root -p example

>use ktv

>db.createUser({
    user: "ktv",
    pwd: "123456",
    roles: [
        { role: "readWrite", db: "ktv-select_music_system" }
    ]
})

14.12.1.3. mongoose连接

mongoose.connect('mongodb://ktv:123456@localhost:27017/ktv-select_music_system')
