run php54 on a hosted website (virtual host)

Install php54 from scl repo

yum --enablerepo=scl-php54 install php54-php.x86_64  

Verify the installation,

 scl enable php54 'php -v' 

It should return this version (or higher)

PHP 5.4.16 (cli) (built: Jul 10 2014 10:06:38)

Create a template fragment that will enable apache to invoke php54 for a virtual domain

nano /etc/e-smith/templates/etc/httpd/conf/httpd.conf/VirtualHosts/70php54

paste this code fragment (including the last empty line):

{ 
  use esmith::DomainsDB;
  my $domains = esmith::DomainsDB->open_ro;
	if (($domains->get_prop($virtualHost, 'php54') || 'disabled')
         eq 'enabled')
		{
				$OUT = "    #Enable php54 through Cgi-Bin wrapper. Needs a wrapper script in /cgi-bin/php54-wrapper\n";
				$OUT .= "    AddHandler php-cgi .php\n";
				$OUT .= "    Action php-cgi /cgi-bin/php54-wrapper\n";
				$OUT .= "    <Location />\n";
				$OUT .= "       Options +ExecCGI\n";
				$OUT .= "    </Location>\n";
		}
 }

and Save with <CTRL>-X - yes.

Create the cgi-wrapper script:

nano ~<Ibayname of MyVirtualDomain>/../cgi-bin/php54-wrapper

Insert this code fragment:

#!/bin/bash
source /opt/rh/php54/enable
exec php-cgi

and Save with <CTRL>-X - yes.

Then execute these commands:

cd ~<Ibayname of MyVirtualDomain>/../cgi-bin/
restorecon -RF php54-wrapper
chown www:www php54-wrapper
chmod ugo-rwx php54-wrapper
chmod ug+rx php54-wrapper

The template fragment for httpd.conf needs a database setting to be enabled for the (virtual) domain.

Check with

db domains show <myVirtualDomain.com>

Edit with

db domains setprop <myVirtualDomain.com> php54 enabled

To enable this run:

expand-template /etc/httpd/conf/httpd.conf
/etc/init.d/httpd-e-smith restart

Notes:

• This version of php uses the /opt/rh/php54/root/etc/php.ini file which uses default settings as configured by RedHat, use at your own risk. Adjust the settings according to your (security) needs.
• Using Cgi-Bin wrapper scripts makes your system vulnerable to Shellshock server bash vulnerability, make sure your server runs the latest version of bash.
• This example and code still have to be tested (I will soon).
