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/
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
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 CAPC need to be performed.
