Configure Backup Agent for SSL¶
On this page
Overview¶
If your MongoDB deployment uses SSL, then you must configure the Backup Agent to use SSL to connect to your deployment’s mongod and mongos instances.
Configuring the agent to use SSL involves specifying which certificate to use to sign MongoDB certificates and turning on the SSL option for the MongoDB instances in Ops Manager.
Prerequisite¶
To configure the agent to use SSL, you must have a trusted CA certificate that signed the MongoDB instance’s certificate.
Procedures¶
Connections between Agents and MongoDB Instances¶
To use SSL for the Backup Agent’s connection to a MongoDB host, specify the host’s SSL settings when adding the host or by editing the host’s settings.
Note
In Ops Manager 1.8 and later, Ops Manager can manage SSL for you if you using Automation for the deployment. With Automation, Ops Manager prompts you for the certificates to use to connect to the deployment when you enable SSL and then configures the agents appropriately. See: Enable SSL for a Deployment for more information.
Specify path to trusted CA certificate.¶
Edit the Backup Agent configuration file
to set the
sslTrustedServerCertificates
field to the path of a file containing
one or more certificates in PEM format. For example:
The agent configuration file is located in either the agent install
directory or the /etc/mongodb-mms/
directory, depending on your
operating system.
By default, to connect to MongoDB instances using SSL requires a
valid trusted certificate. For testing purposes, however, you can set
the sslRequireValidServerCertificates
setting to
False
to bypass this check. This configuration is not
recommended for production use as it makes the connection insecure.
For additional information on these settings, see MongoDB SSL Settings.
Restart agent.¶
Connections between Agents and Ops Manager¶
To ensure that the Backup Agents use SSL when connecting to Ops Manager, Configure Ops Manager to use SSL for all connections. The Configure SSL Connections to Ops Manager tutorial describes how to set up Ops Manager to run over HTTPS.
Starting with Ops Manager 1.4, the Backup Agent validates the SSL certificate of the Ops Manager server by default.
If you are not using a certificate signed by a trusted 3rd party, you must configure the Backup Agent to trust the Ops Manager server.
To specify a self-signed certificate of the Ops Manager server that the Backup Agent should trust:
Copy your PEM certificate to /etc/mongodb-mms/
