Question

美好的一天，

我在mongodb中有一个如下所示的用户，该用户具有超级用户特权（我使用show users命令确认了角色设置）

{
    "_id" : "admin.mongoadmin",
    "user" : "mongoadmin",
    "db" : "admin",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "admin"
        },
        {
            "role" : "root",
            "db" : "admin"
        }
    ],
    "mechanisms" : [
        "SCRAM-SHA-1",
        "SCRAM-SHA-256"
    ]
}

当我尝试使用mongorestore还原操作日志时，出现错误：

失败：还原错误：应用操作日志时出错：applyOps：未经管理员授权执行命令 {applyOps：[{ts：时间戳（1552828309，1），h：4632811839329880092，v：2， op：“ c”，ns：“ admin。$ cmd”，o：{创建：“ system.keys”，idIndex：{v：2，key：{_id：1}，name：“ id “，ns：” admin.system.keys“}}，o2：{}}]，$ db：” admin“}

注意：我将oploglimit（--oplogLimit = 1552828432）指定为从bsondump获得的最后一个值它是否正确？还是我错过了什么？

（即）

{"ts":{"$timestamp":{"t":1552828432,"i":79}},"t":{"$numberLong":"1"},"h":{"$numberLong":"-2072015676601300967"},"v":2,"op":"i","ns":"inventory.hari","ui":{"$binary":"avdlGH8AS1eBPXRytlO1Yg==","$type":"04"},"wall":{"$date":"2019-03-17T13:13:52.139Z"},"o":{"_id":"79","name":"Hari","role":"Developer","isEmployee":true}}

感谢任何帮助。提前致谢。

Answer 1

use admin

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

db.createUser({
  user: "root",
  pwd: "password",
  roles: [
    {role: "root", db: "admin"},"__system","interalUseOnlyOplogRestore","backup"
  ]
})

最好将特权减少到如下所示。

db.createUser({
  user: "root2",
  pwd: "password",
  roles: [
    "interalUseOnlyOplogRestore"
  ]
})

此后，您可以运行restore命令

mongorestore --port 27017 --oplogReplay oplogRestore --authenticationDatabase admin -u root2 -p password

MongoDB：applyOps：未经管理员授权执行命令
