MongoDB基础操作

进入
mongo.exe

创建用户
use admin
db.createUser(
   {
     user: "root",
     pwd: "root",
     roles:
       [
         { role: "readWrite", db: "config" },
         "clusterAdmin"
       ]
   }
)

远程访问
mongod.cfg
net:
  port: 27017
  #bindIp: 127.0.0.1
  bindIp: 0.0.0.0



MongoDB中每个数据库之间是相互独立的，都有独立的权限，正确的做法是使用root账号在【将要操作的数据库】中创建一个【子账号】，在用这个子账号连接mongo

例如：
>use admin
switched to db admin
>db.auth("root","123456")
1
>show dbs
admin
local
testDB
>use testDB
switched to db testDB
>db.createUser(
        {
            user:"usertest",
            pwd:"123456",
            roles:[{role:"dbOwner",db:"testBD"}]
        }
)

Successfully added user: {
  "user" : "usertest",
  "roles" : [
    {
      "role" : "dbOwner",
      "db" : "testDB"
    }
  ]
}
