Connecting to the Mongo Shell

The Mongo shell is a powerful command line utility which can be used to perform CRUD operations againt your database. We highly recommend this tool although you can also use GUI based IDE tools as well.

For a complete overview on the usage of the Mongo shell, reference the MongoDB docs. The basic command required to connect to connect to your database from Mongo shell is of the below format

mongo host:port/databasename -u username -p password For SSL enabled connections. mongo host:port/databasename -u username -p password --ssl --sslCAFile /home/my_nodechef_ca_file For SSL enabled connections without the sslCAFile. mongo host:port/databasename -u username -p password --ssl --sslAllowInvalidCertificates

Connecting to the Local database which contains the oplog

To connect to your local database, simply change the databasename parameter in the connection string to "local" and add the query string "?authSource=databasename"

For example, for the given connection string. mongodb://cat:meow@cat-1.noodechef.com/cat You can use the below connection string to connect to the local database. mongodb://cat:meow@cat-1.nodechef.com/local?authSource=cat
