Mongo-Connector，MongoDB OPLOG和ElasticSearch配置

Question

我有一个简单的问题，只有专家才能回答。这种配置是否可行？

• host1 - 运行mongo-connector
• host2 - 运行ElasicSearch
• host3 - 运行MongoDB（replicamode）

百万美元的问题是：我可以使用mongo-connector将MongoDb中发生的更改传播到ElasticSearch吗？底层问题是MongoDB opLog文件。 Mongo-Connector使用该文件来检测对ElasticSearch的crud操作。如何在这种配置下工作？

Answer 1

在做了涉及两个macbooks的简单测试后回答了我自己的问题。

I did the following to test.

1. 在macBook上运行mongo-connector。
2. 将mongo-connector配置为连接到在不同Macbook上运行的MongoDB ..并连接到在不同macBook上运行的ElasticSearch引擎。
3. 请注意，mongoDB和Elastic Search Engine在此配置中位于同一个框中。

what I observed:
Mongo-connector was able to monitor the mongodb running remotely and was able to
 update Elastic search with all changes that hit the MongoDB. I started with 
an empty ElasticSearch. Mongo-Connector was able to load all historical data 
and then proceeded to load any real-time inserts/updates and deletes on 
Mongodb into Elastic Search.

The trick is this: Use REAL IP ADDRESSES IN YOUR CONFIGURATION FILES.
