Mongo attempts to connect on port 27017 even if you specify a different port

[ghub2015]

OS: Ubuntu Server 14.04

If you modify /opt/sandia/webapps/scot3/scot.conf to utilize an alternative port for Mongo (let's say port 27021 for this example), even though SCOT acknowledges the alternative port, SCOT still tries to connect to the MongoDB using port 27017.

Edit: Here is the config snippet from scot.conf:

                    'database' => {
                                    'write_safety' => 1,
                                    'port' => 27021,
                                    'db_name' => 'scotng-prod',
                                    'host' => 'mongodb://<YourMongoDBHostname>',
                                    'user' => 'scot',
                                    'pass' => 'password'
                                  }

Here is the output from /var/log/scot.prod.log (I added ** for emphasis, since I can't add bolding inside code tags)

The MongoDB::Client has changed and the port field in the config isn't really used anymore. You can change your config to the following:

host => 'mongodb://<yourHost>:<yourPort>'

and everything should work for you.

See http://search.cpan.org/~friedo/MongoDB-0.502.0/lib/MongoDB/MongoClient.pm#host
for more connection option information.

Sorry about the confusion....

Hi Todd, thanks for the followup.

Accordingly, the value of the Port field is therefore irrelevant, correct?
(i.e., we could set it to 0 if we wanted to, for readability/reduce confusion?)

[toddbruner]

Yes, you are correct.
