So, if we want to add existing server, under the wing of MongoOps Manager, we have to do the following:

1. Download & Install the RPM on the
2. Configure the agents with the MongoOps using ApiKey and Endpoint URL

That is that. After that, we will be able to install whatever we want from the MongoOps manager. So let's get started:

In fact, when you go to MongoOps → All clusters → Agents → Download & Settings, there is a easy way how to do the steps. Just follow them :)

[root@dbpahfgcl ~]# curl -OL http://secretMongoOpsUrl:8080/download/agent/automation/mongodb-mms-automation-agent-manager-10.2.18.5978-1.x86_64.rhel7.rpm

[root@dbpahfgcl ~]#
[root@dbpahfgcl ~]# rpm -U mongodb-mms-automation-agent-manager-10.2.18.5978-1.x86_64.rhel7.rpm
[root@dbpahfgcl ~]#

You see, wasn't so hard :) Now for the tricky part.

To configure the agent we need:

• GroupId
• ApiKey
• MongoOps URL

In my case they are:

• Secret
• Secret
• and Secret

You have to configure them in:

/etc/mongodb-mms/automation-agent.config

Once all this is done, we can start the agent as follows:

[root@dbpahfgcl ~]# vi /etc/mongodb-mms/automation-agent.config
[root@dbpahfgcl ~]# chown mongod:mongod /data
[root@dbpahfgcl ~]# systemctl start mongodb-mms-automation-agent.service
[root@dbpahfgcl ~]# systemctl status mongodb-mms-automation-agent.service
