如何在 MongoDB v3 中创建用户？
要在MongoDBv3中创建用户，请使用createUser()方法。这允许您创建用户，并且在创建时您还需要添加用户、密码和角色。这些角色分配权限。语法如下-
use admin
db.createUser(
{
user: “yourUserName",
pwd: "yourPassword",
roles: [ { role: "yourPermission", db: "yourDatabase" } ]
}
);让我们实现上述语法以在MongoDBv3中创建用户-
> use admin
switched to db admin
> db.createUser(
... {
... user: "Robert",
... pwd: "robert",
... roles: [ { role: "readWrite", db: "sample" } ]
... }
... );上面，我们为新用户设置了以下内容-
User: Robert
Password: robert
Roles: readWrite
This will produce the following output:
Successfully added user: {
"user" : "Robert",
"roles" : [
{
"role" : "readWrite",
"db" : "sample"
}
]
}我们已经成功地在上面创建了一个新用户“Robert”。
