Help correcting a mistake

[jacobtennant]

After my problems yesterday I decided to do a fresh clean install of OTRS on a fresh install of CentOS 6.4. and OTRS 3.3.1-01

I got everything installed up to the point where installer.pl was running and told me Kernel.Config.pm was not writeable so I attempted to run

./opt/otrs/bin/otrs.SetPermissions.pl --otrs-user=<OTRS_USER> --web-user=<WEBSERVER_USER> --otrs-group=<OTRS_GROUP> --web-group=<WEB_GROUP> /opt/otrs

in which I created a any users or groups not already created and ended up running it as this...

./opt/otrs/bin/otrs.SetPermissions.pl --otrs-user=otrs --web-user=apache --otrs-group=apache --web-group=web /opt/otrs

Now when I try to run the installer I am told I do not have permission to access /otrs/installer.pl

SInce I am still new to linux, how can I correct this or reset the permissions I changed back to their default settings?
