Apache settings

CenOS 5.5 install had these areas of interest:

Apache:: DBI issue

Error creating thumbnail: Unable to save thumbnail to destination

My Fix: Install Apache::DBI via MCPAN, edit PERL script, then restart httpd.

Steps to fix

Install Apache::DBI:

  • Method 1
# perl -MCPAN -e shell
cpan> install Apache::DBI
  • Method 2 (Make sure that rpmforge repository is configured)
# yum install perl-Apache-DBI

Configure Apache::DBI in /opt/otrs/scripts directory edit apache2-perl-startup.pl script:

root@/opt/otrs/scripts# vi apache2-perl-startup.pl

Edit these lines (removed comment '#' marks and added OTRS user passcode):

use Apache::DBI ();
Apache::DBI->connect_on_init('DBI:mysql:otrs', 'otrs', 'otrs_user_passcode_goes_here');

Restart httpd:

root@/opt/otrs/scripts# service httpd restart
Stopping httpd: [  OK  ]
Starting httpd: [  OK  ]
