Configure MongoDB Agent to Use TLS
On this page
Ops Manager uses TLS to encrypts connections between MongoDB Agent and:
MongoDB instances.
Ops Manager.
Prerequisite
To configure the MongoDB Agent to use TLS, you must:
Have the trusted Certificate Authority certificate that signed the MongoDB instance's certificate.
Ensure that all TLS certificates contain the Subject Alternative Name field.
Procedures
Configure Connections between MongoDB Agent and MongoDB Instances
To use TLS for the MongoDB Agent's connection to a MongoDB deployment, specify the deployment's TLS settings when adding the deployment or editing the deployment's settings.
Note
Ops Manager can manage TLS for you if you are using Automation for the deployment. With Automation, Ops Manager prompts you for the certificates to use to connect to the deployment when you enable TLS and then configures the agents appropriately. To learn how to configure TLS, see Enable TLS for a Deployment.
Configure Connections between MongoDB Agent and Ops Manager
To ensure that the MongoDB Agent uses TLS when connecting to Ops Manager, configure Ops Manager to use TLS for all connections. The Configure TLS Connections to Ops Manager tutorial describes how to set up Ops Manager to run over TLS.
By default, the MongoDB Agent validates the Ops Manager TLS certificate.
If a trusted third party did not sign your certificate, you must configure the MongoDB Agent to trust Ops Manager.
To specify a self-signed certificate for Ops Manager that the MongoDB Agent should trust:
Install your certificate file to your Ops Manager configuration directory.
Copy your TLS certificate to your Ops Manager configuration directory:
The location of the MongoDB Agent configuration directory is
C:\MMSData\Automation\
.
Note
The MongoDB Agent configuration directory is named
Automation
to simplify upgrades
for those using legacy agents.
The location of the MongoDB Agent configuration file is
/etc/mongodb-mms/
.
The location of the MongoDB Agent configuration file is
/etc/mongodb-mms/
.
The location of the MongoDB Agent configuration file is
/path/to/install/
.
Then, set the mongodb
system user as the owner of
the TLS certificate. Grant that user read and write
permissions on the certificate.
Example
For Linux operating systems, use the following commands to set ownership and permissions:
sudo cp -a mms-ssl-unified.pem /etc/mongodb-mms/ sudo chown mongod:mongod /etc/mongodb-mms/mms-ssl-unified.pem sudo chmod 600 /etc/mongodb-mms/mms-ssl-unified.pem
Then, set the mongod
system user as the owner of
the TLS certificate. Grant that user read and write
permissions on the certificate.
Example
For Linux operating systems, use the following commands to set ownership and permissions:
sudo cp -a mms-ssl-unified.pem /etc/mongodb-mms/ sudo chown mongod:mongod /etc/mongodb-mms/mms-ssl-unified.pem sudo chmod 600 /etc/mongodb-mms/mms-ssl-unified.pem
Then, set the system user (username of the MongoDB Agent) as the owner of the TLS certificate. Grant that user read and write permissions on the certificate.
Example
For Linux operating systems, use the following commands to set ownership and permissions:
sudo cp -a mms-ssl-unified.pem /etc/mongodb-mms/ sudo chown mongod:mongod /etc/mongodb-mms/mms-ssl-unified.pem sudo chmod 600 /etc/mongodb-mms/mms-ssl-unified.pem
Edit the following parameter in the configuration file.
The location of the MongoDB Agent configuration file is
C:\MMSData\Automation\automation-agent.config
.
Note
The MongoDB Agent configuration file is named
automation-agent.config
as a way to enable easier upgrades
for those using legacy agents.
The location of the MongoDB Agent configuration file is
/etc/mongodb-mms/automation-agent.config
.
Note
The MongoDB Agent configuration file is named

The location of the MongoDB Agent configuration file is
/etc/mongodb-mms/automation-agent.config
.
Note
The MongoDB Agent configuration file is named

The location of the MongoDB Agent configuration file is
/path/to/install/local.config
.
Example
The following setting specifies the
httpsCAFile
file as
/etc/mongodb-mms/mms-ssl-unified.pem
.
If you don't want to have Ops Manager validate the SSL certificates, set
Client Certificate Mode
to None.
