Question

我想知道，有没有办法可以通过mongo-connector从一个mongo副本集复制到另一个mongo副本集？根据mongo文档，我们可以通过mongo-connector使用命令连接两个mongo实例，如下例所示，但我想传递副本集名称或使用配置文件而不是传递 server：port 命令行中的名称。

Mongo Connector可以使用Mongo DocManager从一个MongoDB副本集或分片集群复制到另一个集群。最基本的用法如下：

mongo-connector -m localhost：27017 -t localhost：37017 -d mongo_doc_manager

我也通过创建下面的config.json文件尝试了config.json选项，但它失败了。

{
    "__comment__": "Configuration options starting with '__' are disabled",
    "__comment__": "To enable them, remove the preceding '__'",

    "mainAddress": "localhost:27017",
    "oplogFile": "C:\Dev\mongodb\mongo-connector\oplog.timestamp",
    "verbosity": 2,
    "continueOnError": false,

    "logging": {
        "type": "file",
        "filename": "C:\Dev\mongodb\mongo-connector\mongo-connector.log",
        "__rotationWhen": "D",
        "__rotationInterval": 1,
        "__rotationBackups": 10,
        "__type": "syslog"        
    },

    "docManagers": [
        {
            "docManager": "mongo_doc_manager",
            "targetURL": "localhost:37010",
            "__autoCommitInterval": null
        }
    ]
}

是的，可以使用mongo连接器连接到副本集或分片服务器。

 {
mongo-connector -m <mongodb server hostname>:<replica set port> \
            -t <replication endpoint URL, e.g. http://localhost:8983/solr> \
            -d <name of doc manager, e.g., solr_doc_manager>
}

您还可以将连接字符串传递给mongo-connector，例如

{
mongo connector -m mongodb://db1.example.net,db2.example.net:2500/?replicaSet=test&connectTimeoutMS=300000

}

指定可以使用的特定配置文件

{ mongo-connector -c config.json }

其中config.json是您的配置文件。

我可以通过为我的Windows目录路径输入反斜杠'\'来解决我的问题。这是我更新的配置文件以供参考。感谢ShaneHarvey Not able to use Configuration file for connecting to mongo-connector

{
    "__comment__": "Configuration options starting with '__' are disabled",
    "__comment__": "To enable them, remove the preceding '__'",

    "mainAddress": "localhost:27017",
    "oplogFile": "C:\\Dev\\mongodb\\mongo-connector\\oplog.timestamp",
    "noDump": false,
    "batchSize": -1,
    "verbosity": 2,
    "continueOnError": false,

    "logging": {
        "type": "file",
        "filename": "C:\\Dev\\mongodb\\mongo-connector\\mongo-connector.log",
        "__format": "%(asctime)s [%(levelname)s] %(name)s:%(lineno)d - %(message)s",
        "__rotationWhen": "D",
        "__rotationInterval": 1,
        "__rotationBackups": 10,
        "__type": "syslog",
        "__host": "localhost:27017"        
    },  


    "docManagers": [
        {
            "docManager": "mongo_doc_manager",
            "targetURL": "localhost:37017",
            "__autoCommitInterval": null
        }
    ]
}

我可以使用副本集名称通过mongo-connector
