如何使用 mongo-connector 连接到远程 MongoDB？

Question

如何使用 mongo-connector 连接到 Mongo Atlas 上的 MongoDB 集群？

我尝试使用以下命令连接到我的集群：

第一次尝试

sudo mongo-connector -m "mongodb://g******:*********@rest-api-data-shard-00-00-xemv3.mongodb.net:27017,rest-api-data-shard-00-01-xemv3.mongodb.net:27017,rest-api-data-shard-00-02-xemv3.mongodb.net:27017/admin?ssl =true&replicaSet=rest-api-data-shard-0&authSource=admin" -a g****** -p "***********" -t http://localhost:9200 -d elastic2_doc_manager

回应：

Logging to mongo-connector.log.

You must logout first.

第二次尝试：

sudo mongo-connector -m "mongodb://rest-api-data-shard-00-00-xemv3.mongodb.net:27017,rest-api-data-shard-00-01-xemv3.mongodb.net:27017,rest-api-data-shard-00-02-xemv3.mongodb.net:27017/admin?replicaSet=rest-api-data-shard-0" -a g********* -p "********" -t http://localhost:9200 -d elastic2_doc_manager

在github issue 上回答。解决方案：

在您的第一次尝试中，问题是您为 MongoDB 指定了用户名和密码两次。删除 -a g****** -p "***********" 它应该可以正常工作。如果您需要对 Elasticsearch 进行身份验证，则需要使用 mongo-connector 配置文件并为 Python Elasticsearch 客户端设置正确的身份验证选项，例如：

{ "mainAddress": "mongodb://user:pass@mongodb:27017,mongodb:27018,mongodb:27019/admin?ssl=true&replicaSet=name&authSource=admin", "verbosity": 1, "docManagers": [ { "docManager": "elastic2_doc_manager", "targetURL": "http://localhost:9200", "args": { "clientOptions": { "http_auth": ["user", "secret"], "use_ssl": true } } } ] }

在您的第二次尝试中，问题似乎是您忘记将 ssl=true 添加到 MongoDB 连接字符串。这就是您因对等错误而重置连接的原因。
