MongoDB: applyOps：未获得在admin上执行命令的授权

Question

你好，

我在mongodb中有一个用户，拥有超级用户权限（通过使用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来恢复oplog时，我遇到了以下错误：

失败：恢复错误：应用oplog时出错：applyOps: 未被授权在admin上执行命令 { applyOps: [ { ts: 时间戳(1552828309, 1), h: 4632811839329880092, v: 2, op: "c", ns: "admin.$cmd", o: { create: "system.keys", idIndex: { v: 2, key: { _id: 1 }, name: "id", ns: "admin.system.keys" } }, o2: {} } ], $db: "admin" }

注意：我使用bsondump获得的最后一个值指定了oploglimit(--oplogLimit=1552828432)。

这是正确的吗？还是我错过了什么？

{"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}}

任何帮助都受到欢迎。提前致谢。

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"
  ]
})

更好的做法是将权限降低到类似以下的级别。

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

完成此步骤后，您可以运行恢复命令。

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