Software fails to install due to SELinux

I don't know why but you can find a lot of software that fails to install with SELinux (Security Enhanced Linux) turn it on.

How can we turn it off?

Temporarily:
Just enter the following command as root user:

setenforce 0

Permanently:
Edit, as root, the file:

/etc/selinux/config

You can set the SELINUX line to one of :

SELINUX=enforcing
SELINUX=permissive
SELINUX=disabled

Permissive could be the best choice, but if you want if off completely and set it to disabled, you will also have to update the grub.conf file or the machine will not boot!

Add enforcing=0 as follows to the boot line:

kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/ rhgb quiet enforcing=0
