Most powerful CMS system - Joomla!

I tried it today and found it's really useful and the UI looks pretty good.

I'll try it more later and might integrate with some projects.

Trouble shooting Apache not allow symbol link problem, resolved

I did some modifications to my apache server. And I created a symbol link to the use a larger storage space driver. But after that, I found my apache threw an 403 error. And after check the apache error_log file, I found an error said: [error] [client] Symbolic link not allowed: /var/www/html/test. I was curious about this, because we had another server with the same configuration and same symbol link under /var/www/html/ directory. Why the behaviors are so different?

To resolve the symbol link not allow problem, I change the httpd configuration from:
Options FollowSymLinks
Options Indexes FollowSymLinks
Options +FollowSymLinks
Options Indexes +FollowSymLinks
in the DocumentRoot directory definition part.

But it dosn't work. So I did more google. And in one forum somebody said this is because the SeLinux problem, I need to disable SELinux to resolve this problem.

To disable SELinux, we can temporarily disable or permanently disable it:
a. temp

You'll need to be logged in as root, and in the sysadm_r role:
newrole -r sysadm_r
and then
echo 0 >/selinux/enforce
To switch back into enforcing mode:
echo 1 >/selinux/enforce

b. permanently
edit /etc/selinux/config and change SELINUX=enforcing to SELINUX=permissive

For more detail, please check this artical :
