如何在具有正确角色的现有数据库上创建MongoDB用户？
要在MongoDB中创建新用户，请使用createUser()。以下是查询-
> db.createUser(
... {
... user: "John",
... pwd: "123456",
... roles: [ { role: "readWrite", db: "test" } ],
... mechanisms: [ "SCRAM-SHA-256" ]
... }
... )这将产生以下输出-
Successfully added user: {
"user" : "John",
"roles" : [
{
"role" : "readWrite",
"db" : "test"
}
],
"mechanisms" : [
"SCRAM-SHA-256"
]
}以下是显示所有用户的查询-
> db.getUsers();
这将产生以下输出-
[
{
"_id" : "test.John",
"user" : "John",
"db" : "test",
"roles" : [
{
"role" : "readWrite",
"db" : "test"
}
],
"mechanisms" : [
"SCRAM-SHA-256"
]
}
