Hi Shebina, The problem is caused because SELinux audits your system, adding what essentially is another level of permissions. You can view the SELinux permissions of a file with ls -Z; then, you'll need to relabel the Koha files and directories to the correct label for the system to run with SELinux enabled. (check /var/www/ for the right permissions) You can repabel with the 'fixfiles' tool using 'relabel'. Also, you may need to run mysql_install_db as per the Koha instructions for Fedora Core. The process of managing SELinux is complicated and if you're going to run it you should read through the Fedora Core SELinux FAQ (for FC3): http://fedora.redhat.com/docs/selinux-faq-fc3/ Hope that helps, -- Joshua Ferraro VENDOR SERVICES FOR OPEN-SOURCE SOFTWARE President, Technology migration, training, maintenance, support LibLime Koha ILS, Mambo Intranet, DiscrimiNet Filter jmf@liblime.com | Full Demos at http://liblime.com | 1(888)KohaILS
