创建 MongoDB 的超级用户的方法

以下是创建MongoDB超级用户的方法。

在没有认证的情况下，创建用户。

$ mongosh
test> use admin
switched to db admin
admin> db.createUser({user: "scott",pwd: "tiger123",roles: ["userAdminAnyDatabase","readWriteAnyDatabase","dbAdminAnyDatabase"]})
{ ok: 1 }
admin> 

要启用身份验证，请更改设置并重新启动mongodb。

# 略
auth=true

sudo systemctl restart mongodb

确认能够登录

$ mongosh admin -u scott -p tiger123

   The server generated these startup warnings when booting:
   2022-03-06T09:08:46.696+09:00: Using the XFS filesystem is strongly recommended with the WiredTiger storage engine. See http://dochub.mongodb.org/core/prodnotes-filesystem

admin> 

使用脚本创建的方法

db.createUser({user: "scott",pwd: "tiger123",
	roles: ["userAdminAnyDatabase","readWriteAnyDatabase",
	"dbAdminAnyDatabase"]
	})

运行命令

mongosh admin < create_user.js

删除用户

$ mongosh
test> use admin
switched to db admin
admin> db.dropUser('scott')
{ ok: 1 }
admin>
