Connect to replication set #3

Closed gms-roll-out closed 4 years ago

gms-roll-out commented 4 years ago

Hi,

Is it possible to connect a replication set ?

kagahd commented 4 years ago

Hello, the performance test is designed to run only against a single host. This makes it easier to detect performance differences caused by different mongodb versions or different hardware. However, the open source code can be easily adapted to connect against a replSet.

Hi, I tried to run against a single instance (primary) in a replica set but am getting an error is that because I can't do it this way ?

You should be able to connect to a single instance (primary) of the replSet. I just tried it successfully. How is your command line or connection string?

Thanks for trying and quick reply

Im using :

java -jar mongodb-performance-test.jar -m insert -o 100 -t 10 20 -db testing -c meeting -u demo_db_user -p XXXX -h cluster0-shard-00-02.wjusn.mongodb.net

But actually having problems connecting using equivalent mongo command to connect to replica set primary

I guess I better go away and figure out why I can't get connected on CLI before bothering you, but open to ideas

Seeing:

ben.ritchie@Bens-MacBook-Pro  ~/Documents/dev/connect4  mongo cluster0-shard-00-02.wjusn.mongodb.net/meteor -u demo_db_user -p XXXX MongoDB shell version v4.4.3 connecting to: mongodb:// cluster0-shard-00-02.wjusn.mongodb.net:27017/meteor?compressors=disabled&gssapiServiceName=mongodb

*** You have failed to connect to a MongoDB Atlas cluster. Please ensure that your IP whitelist allows connections from your network.

Error: network error while attempting to run command 'isMaster' on host ' cluster0-shard-00-02.wjusn.mongodb.net:27017' : connect@src/mongo/shell/mongo.js:374:17 @(connect):2:6 exception: connect failed

I've got whitelist as 0.0.0.0/0 and can connect using Compass

I checked auth and it's using SCRAM so I dont think it's SSL

Using SCRAM does not say anything about using SSL or not. So if you use SSL, just add the parameter -ssl to your command.
