Prerequisites

Whitelist CData IPs

To establish a connection to MongoDB, you need to allow access to MongoDB via CData’s IP. When hosting MongoDB behind a firewall, you must safelist these IP addresses in your firewall.

  • Range: 52.224.0.160 to 52.224.0.175

  • CIDR notation: 52.224.0.160/28

Ensure MongoDB is Publicly Accessible

Provide a public facing IP/domain to connect to this data source. The following private IP ranges do not work:

  • 10.0.0.0 to 10.255.255.255

  • 172.16.0.0 to 172.31.255.255

  • 192.168.0.0 to 192.168.255.255

  • 127.0.0.1 (aka ‘localhost’)

Setup Guide

Follow these steps to connect MongoDB to your CData Connect Cloud account:

  1. Open the Connections page of the CData Connect Cloud dashboard.

  2. Click + Add Connection in the upper-right corner.

  3. Type MongoDB into the search field, then click the data source name.

  4. On the Basic Settings tab of the new connection, enter a connection name or keep the default name.

  5. Enter the host name or IP address of the MongoDB server in the Server field.

  6. Specify the port for connecting to the MongoDB server in the Port field. By default this is set to 27017.

  7. Enter the name of the MongoDB Database.

  8. Select the Auth Scheme you use to connect to MongoDB. Options are: MONGODB-CR, SCRAM-SHA-1, SCRAM-SHA-256, and X509.

  9. Enter the MongoDB username for authentication in the User field.

  10. In the Password field, enter the user password.

  11. (Optional) If the authentication database is different from the database to retreive data from, enter it into the Auth Database field.

  12. In MongoDB, add the CData Connect Cloud static IP addresses to your connection whitelist.

  13. At the top of the CData Connect Cloud Add MongoDB Connection page, click Save & Test.

    • If the connection test succeeds, a message indicates that your connection has been created. The Status on the Edit Connection page also changes to Authenticated.

    • If the connection test fails, ensure that you entered your login information correctly with no stray spaces or other characters. CData Connect Cloud displays error messages under the required fields with missing data. Some data sources require that you sign in directly to the source website. If you did not, an error message appears under the Sign in button. Correct the errors and try again.

Connect to Replica Sets

  1. To connect to a replica set, click on Advanced Settings.

  2. Set Replica Set to a list of comma-separated list of secondary servers, specified by address and port.

  3. Set Slave OK to True.

  4. Set Read Preference to determine how the provider reads from the secondary servers.

    • primary executes all SELECT queries against the primary server.
    • primaryprefered executes SELECT queries from a secondary server when the primary is not available.
    • secondary executes SELECT queries on secondary servers only.
    • secondary prefered executes SELECT queries on the primary server in the event no secondaries are available.
    • nearest executes SELECT queries on whichever server has the least latency.
