Hey guys: I have successfully installed Ganglia 3.0.1 on Fedora Core 3 (this probably applies to Red Hat Enterprise Linux 4 as well) and thought I'd share with you some issues I've encountered and solutions. Basically there are 2 issues. SELinux and php-gd. Ganglia 2.5.6 worked fine under Fedora Core 3 with SELinux in permissive mode, however it no longer works with 3.0.1 and therefore SELinux needs to be turned off completely (or you can configured SELinux properly - see this post: http://sourceforge.net/mailarchive/message.php?msg_id=10659480). Since Fedora Core 3, the default php installation does not come with gd, therefore you need to install the separate RPM 'php-gd' such that ganglia can generate and display the pie chart. Ganglia seems to be working fine, and the graphs are generated properly - however, I still have one unresolved issue. In the apache error logs (/var/log/httpd/error_log) I get a lot of following messages. Does anybody have any idea what is causing them?
