So, if we want to add existing server, under the wing of MongoOps Manager, we have to do the following:
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 :)
Download & Install
[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 ~]# 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:
In my case they are:
You have to configure them in:
Configure the Agent
/etc/mongodb-mms/automation-agent.config
Once all this is done, we can start the agent as follows:
Start the agent
[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

That easily can be done from the MongoOps manager, but before you do, be sure to install the required packages:
