Sep 28 14:44:03 SRV su[23612]: pam_unix(su:session): session closed for user cloudera-scm

Can anyone help?

Hello @Vogone,


You have encountered a safeguard which should prevent the reconfiguring of your Cloudera Manager database from its previous setting due to having the embedded database package (cloudera-manager-server-db-2)


First, check to see if your current is correct:

cat /etc/cloudera-scm-server/


If it is not correct, then check for other files in /etc/cloudera-scm-server/ directory to see if any are correct.

copy the correct one to if the current one is not correct.


If you have configured Cloudera Manager to use a non-embedded database (as it seems you have not), then remove the "cloudera-manager-server-db-2" package from your Cloudera Manager host.  When you reboot, it is configured to start.  When cloudera-manager-server-db-2 package starts (cloudera-scm-server-db) it will attempt to configure your to connect to an "embedded" postgres db.


Once you have the correct file configured and the cloudera-manager-server-db-2 package is removed, start Cloudera Manager.
