关闭 mongodb 出错： Error: shutdown failed: not authorized

开启认证功能之后，出现了不能关闭数据库的现象，报错如下：

点击(此处)折叠或打开

1. Error: assert failed : unexpected error: Error: shutdownServer failed: not authorized on admin to execute command { shutdown: 1.0 }

开启的操作是在/etc/mongo.conf,添加如下设置：

1. security:
   
2.   authorization: enabled

从报错内容上看是权限不够，但不明了为什么，因为已经使用的超级用户权限：

1. {
   
2.     "_id" : "admin.myUserAdmin",
   
3.     "user" : "myUserAdmin",
   
4.     "db" : "admin",
   
5.     "roles" : [
   
6.         {
   
7.             "role" : "userAdminAnyDatabase",
   
8.             "db" : "admin"
   
9.         },
   
10.         {
    
11.             "role" : "dbOwner",
    
12.             "db" : "admin"
    
13.         }
    
14.     ]
    
15. }

经过查询错误解决办法，了解到是集群管理权限不够，添加相应权限之后就可以解决问题，变更用户权限如下：

点击(此处)折叠或打开

1. > db.updateUser(
   
2. ... "myUserAdmin",
   
3. ... {
   
4. ... roles : [
   
5. ... {"role" : "userAdminAnyDatabase","db" : "admin"},
   
6. ... {"role" : "dbOwner","db" : "admin"},
   
7. ... {"role" : "clusterAdmin", "db": "admin"}
   
8. ... ]
   
9. ... }
   
10. ... )

成功关闭数据库系统：
