Question

我正在尝试在mongodb中创建一个副本。我使用以下命令制作副本。我得到了以下输出。

 cfg = { _id : "mySet", members : [ { _id : 0, host : "localhost:27017" 
 } ] }    
 rs.initiate(cfg)

输出：

{
"ok" : 0,
"errmsg" : "Attempting to initiate a replica set with name mySet, but command line reports 0; rejecting",
"code" : 93,
"codeName" : "InvalidReplicaSetConfig"
}

我得到以下输出：

017-09-22T14:22:22.093+0530 E QUERY    [thread1] ReferenceError: conf is not defined :
@(shell):1:1

当我运行show dbs和rs.config（）时，我收到以下错误：

show dbs

删除所有复制和oplog。

use local
db.dropDatabase()

重启mongo

config = {_id: "repl1", members:[
{_id: 0, host: 'localhost:15000'},
{_id: 1, host: '192.168.2.100:15000'}]
}
rs.initiate(config);
