CentOS 7 上的 MongoDB 複製集配置問題

我的 mongodb 實例不會獨立執行，我無法找到原因。它可能很簡單。請指出我正確的方向。

Linux myserver 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

mongo -version
MongoDB shell version v4.0.6

執行命令：

> > mongo –host 10.0.0.7/admin –port 27017 -u user -p mypassword > > >

返回：

MongoDB shell version v3.4.13
connecting to: mongodb://admin:27017/?replicaSet=10.0.0.7
2019-03-06T00:54:32.412-0500 I NETWORK  [thread1] Starting new replica set monitor for 10.0.0.7/admin:27017

2019-03-06T00:54:32.914-0500 I NETWORK  [thread1] getaddrinfo("admin") failed: Name or service not known

所以我登錄到主機上的 mongo shell 並執行：

use admin show users

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

和

rs.status()

{
       "ok" : 0,
       "errmsg" : "not running with --replSet",
       "code" : 76,
       "codeName" : "NoReplicationEnabled"
}

mongo –host 10.0.0.7/admin –port 27017 -u user -p mypassword

上面的命令10.0.0.7以replica setnameadmin和hostname. 這就是您收到錯誤的原因。

使用以下任何命令連接到 MongoDB 數據庫

mongo 10.0.0.7/admin --port 27017 -u user -p mypassword

mongo admin --host 10.0.0.7 --port 27017 -u user -p mypassword
