Issue/Introduction

After install process finishes, we see a message saying "Installed with errors": 

Error: Failure to detect datasource: EVENT_MANAGERException: Server returned HTTP response code: 503 for URL: http://localhost:8181/pc/center/webservice/datasources/ 
******** 
java.lang.Throwable 

2018-06-28T17:47:40.979015Z 0 [ERROR] Can't start server: Bind on TCP/IP port: Address already in use 
2018-06-28T17:47:40.979021Z 0 [ERROR] Do you already have another mysqld server running on port: 3306 ? 
2018-06-28T17:47:40.979032Z 0 [ERROR] Aborting 
 

Environment

Component: IMINST

Resolution

We checked the system by running:
ps -ef | grep -i mysql 

There was another mysql server running on the system.

This instance needs to be removed and then an uninstall and reinstall of MySQL and NetOps Portal need to be performed.
