Installing AB on CentOS (with cPanel)

cPanel adds in an exclusion for all packages named httpd* (any files starting with httpd) to prevent accidentally overwriting apache.

SSH into your server.

Edit /etc/yum.conf and remove the entry httpd* from the Exclude line

vi /etc/yum.conf

exclude=bind-chroot courier* dovecot* exim* filesystem httpd* mod_ssl* mydns* mysql* nsd* php* proftpd* pure-ftpd* spamassassin* squirrelmail*

Once the entry has been removed, save the config file and exit.

Run the following command to install ab.

yum install httpd-tools

Make sure to go back into the /etc/yum.conf and add httpd* back to the exclude list, otherwise you risk breaking your cpanel installation.
