MongoDB开启的 --auth 之后,无法使用 db.eval() 问题

     MongoDB开启auth验证后,除了创建用户和授权角色外,在执行一些特殊操作的时候,还是会“not authorized”错误,如在执行eval时会报:

     

Command failed with error 13: 'not authorized on *** to execute command { $eval: "function()...

解决方案:

     在官网  http://docs.mongodb.org/manual/reference/command/eval/#dbcmd.eval 有一段描述:

 

If authorization is enabled, you must have access to all actions on all resources in order to run eval. Providing such access is not recommended, but if your organization requires a user to run eval, create a role that grants anyAction on anyResource. Do not assign this role to any other user.

 

解决步骤:

 

1)不带--auth参数启动数据库,所以不需要帐号即可连上MongoDB。

 

2)新建一个角色,比如叫 sysadmin,需要先切换到admin库进行如下操作:

 

db.createRole({
    role: "sysAdmin",
    privileges: [{
        resource: {
            anyResource: true
        },
        actions: ['anyAction']
    }],
    roles: []
}

 

3)新建一个用户,比如叫 sysUser,授权sysAdmin角色

 

db.createUser({"user":"sysUser","pwd":"123456",roles:[]});

 

db.grantRolesToUser("sysUser",[{role:"sysAdmin",db:"admin"}]);

    特别注意,grant时db一定是指明"admin"

 

4)开启--auth,试一下吧
