1、问题描述
今天在执行db.serverStatus()命令时给出了“ "errmsg" : "not authorized on admin to execute command { serverStatus: 1.0 }",”的错误提示。
通过查询admin的权限已经是dbOwner的权限了,然后又陆续赋予了dbadmin等权限,问题仍旧存在。
最后找到了Mongodb的权限列表,赋予了root权限终于可以把问题给解决了,然后又测试了其他几个权限都不可以,这说明db.serverStatus是服务器级别的命令,需要mongodb的最高权限才能执行。
下面是问题处理的简单流程,分享给大家,以供参考。
2、错误内容
[root@ggnode2 ~]# mongo 10.130.170.112:27017/admin -u admin -p MongoDB shell version: 3.2.8 Enter password: connecting to: 10.130.170.112:27017/admin MongoDB Enterprise > MongoDB Enterprise > db.serverStatus() { "ok" : 0, "errmsg" : "not authorized on admin to execute command { serverStatus: 1.0 }", "code" : 13 }
3、错误分析
从得到的错误内容可知,是由于admin没有执行db.serverStatus()命令的权限。
MongoDB Enterprise > use admin switched to db admin MongoDB Enterprise > show collections system.users system.version MongoDB Enterprise > db.system.users.find() { "_id" : "admin.admin", "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "BEN7SONYkewFMx3f67FNQw==", "storedKey" : "HjlvcjSpXpSKetcUbJyj350Xgjk=", "serverKey" : "k2WEf2cHGgg9n3tyEMJyuKaRt3U=" } }, "roles" : [{ "role" : "dbOwner", "db" : "admin" } ] }
根据查询结果可知,admin拥有dbOwner角色权限,而执行db.serverStatus()命令需要root角色权限。
4、问题处理:
经过查询表system.users表可知,需要为admin用户赋予root角色才能执行db.serverStatus()命令。
赋予角色权限的操作命令如下:
授予角色权限
MongoDB Enterprise > db.grantRolesToUser( "admin" , [ { role: "root", db: "admin" } ]) MongoDB Enterprise >
取消角色权限
MongoDB Enterprise > db.revokeRolesFromUser( "admin" , [ { role: "root", db: "admin" } ] MongoDB Enterprise >
5、问题解决
赋予root角色权限之后,再执行db.serverStatus()命令就OK了,执行结果如下:
MongoDB Enterprise > db.serverStatus()
MongoDB shell version: 3.2.8
