Error when trying to create event service - Connection Refused Error

[Luiz.Polli]

Hi experts,

I have created a new event service in a demo deployment, but it is failing to start up. I'm seeing some errors for failed to connect to in platform-admin-server.log.

Could anyone help me on that?

This is the solution that worked for me ....

Ensure entry in /etc/hosts  containing the EC hostname as I'm installing the Event Service locally.

platform-admin.sh stop-platform-admin

Edit <platform_home>/mysql/db.cnf and  made the following change:

From:

user=root

To:

user=appd

Change the ownership of all the files in the EC home directory.

chown -R appd:appd /opt/appdynamics

platform-admin.sh start-platform-admin

Remove the Events Service, and then deploy it again locally to the EC host.

Events Service started OK.
