linux mongo 创建用户

____tz_zs

启动 mongo 的 shell

$ mongo

MongoDB shell version: 3.2.6
connecting to: test

切换到 admin 库

> use admin

switched to db admin

查看表

> show collections

system.users

system.version

查看所有的用户

> db.system.users.find()

创建管理员账号

> db.createUser(
{user:'user',
 pwd:'passwd', 
 roles:[
   {role:'userAdminAnyDatabase', db:'admin'}
]
})

.

切换到具体的库

> use tzzs

switched to db tzzs

.

创建这个数据库的用户

> db.createUser(  
...   { user: "tz",  
...     pwd: "tz123456",  
...     roles: [ { role: "readWrite", db: "tzzs" }]  
...   }  
... ) 

.

出现下面的文字说明创建成功

Successfully added user: {
"user" : "tz",
"roles" : [
{
"role" : "readWrite",
"db" : "tzzs"
}
]
}

查看用户

> show users

{
"_id" : "tzzs.tz",
"user" : "tz",
"db" : "tzzs",
"roles" : [
{
"role" : "readWrite",
"db" : "tzzs"
}
]
}
{
"_id" : "tzzs.tz2",
"user" : "tz2",
"db" : "tzzs",
"roles" : [
{
"role" : "readWrite",
"db" : "tzzs"
}
]

}

.

如果有安装可视化软件，我们可以很明显的看到这个过程

①进入 admin 库的过程，就是在查看这个结构的表

.

②创建管理员账号就是创建了以下这条记录

.

③以下是在 tzzs 库下建的两个用户
