Multiple PHP versions on i686

Hi
Below is my Server installation info:
Operating system CentOS Linux 6.9
Webmin version 1.831
Virtualmin version 5.07.gpl
Kernel and CPU Linux 2.6.32-573.el6.i686 on i686

I was trying to install multiple PHP versions on my server as per Docs provided here ( https://www.virtualmin.com/documentation/web/multiplephp )

But on very first step I get

[root@server ~]# yum install centos-release-scl
Loaded plugins: fastestmirror, security
Setting up Install Process
Loading mirror speeds from cached hostfile

Any Suggestion
Regards

Rizwan
