修改配置文件，mongodb配置文档

配置绑定 任何ip都可连接mongodb，把 bindIp: 127.0.0.1 改为 0.0.0.0

[root@localhost lz]# cd /etc/
[root@localhost etc]# vi mongod.conf 

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

复制代码

启动mongoDB

1. 启动

   sudo systemctl start mongod
   复制代码

2. 验证MongoDB是否已成功启动

   sudo systemctl status mongod
   复制代码

   确保MongoDB将在系统重新启动后启动

   sudo systemctl enable mongod
   复制代码

3. 停止MongoDB

   sudo systemctl stop mongod
   复制代码

4. 停止MongoDB

   sudo systemctl restart mongod
   复制代码

5. 开始使用MongoDB

   mongo
   复制代码

使用 mongodb-shell 创建用户, shell 文档

1. 连接mongo

   [root@localhost /]# mongo
   MongoDB shell version v4.4.5
   connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
   Implicit session: session { "id" : UUID("b85be611-cc9a-421e-b5a1-ba7fa307b5ec") }
   MongoDB server version: 4.4.5
   ---
   The server generated these startup warnings when booting: 
           2021-04-22T11:56:40.921+08:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted
   ---
   ---
           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()

2. 创建超级管理员账号

   > use admin
   switched to db admin
   > db.createUser({user:'root',pwd:'123456', roles:[{role:'root', db:'admin'}]})
   Successfully added user: {
           "user" : "root",
           "roles" : [
                   {
                           "role" : "root",
                           "db" : "admin"
                   }
           ]
   }
   > 
   复制代码

   命令详解

   {
       user: 'root', // 用户名
       pwd: '123456', // 密码
       roles: [        // 角色配置
           {
               role: 'root', // root 超级管理员, mongodb 内置角色
               db: 'admin'     // 数据库
           }
       ]
   }
   复制代码

3. 使用用户管理账户登录认证

   > db.auth('root','123456')
   1
   > 
   复制代码
