# Docker安装MongoDB
# Docker安装MongoDB
MongoDB是一个NoSQL的非关系型数据库 ，支持海量数据存储，高性能的读写
# 安装
- 拉去镜像
docker pull mongo:4.4
1
- 创建mongo数据持久化目录
mkdir -p /docker_volume/mongodb/data
1
- 运行容器
docker run -itd --name mongo -v /docker_volume/mongodb/data:/data/db -p 27017:27017 mongo:4.4 --auth
1
-v: 将宿主机的/docker_volume/mongodb/data映射到容器的/data/db目录，将数据持久化到宿主机，以防止删除容器后，容器内的数据丢失
–auth：需要密码才能访问容器服务
# 创建用户
- 登录mongo容器，并进入到【admin】数据库
docker exec -it mongo mongo admin
1
- 创建一个用户，mongo 默认没有用户
db.createUser({ user:'root',pwd:'123456',roles:[ { role:'userAdminAnyDatabase', db: 'admin'},'readWriteAnyDatabase']});
#【user:‘root’ 】：设置用户名为root
#【pwd:‘123456’】：设置密码为123456
#【role:‘userAdminAnyDatabase’】：只在admin数据库中可用，赋予用户所有数据库的userAdmin权限
#【db: ‘admin’】：可操作的数据库
#【‘readWriteAnyDatabase’】：赋予用户读写权限

# 连接、测试
- 连接mongo数据库
db.auth('root', '123456')
1
- 测试数据库，插入一条语句

1
- 测试数据库，查询刚才插入的语句
db.user.find()

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
