As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, especially to check compatibility with this common version, and  to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL.

Installation :

yum --enablerepo=remi install php55

emblem-important-2-24.pngTo be noticed:

  • as the SCL is independant from the system, and doesn't alter it, this SCL is available in remi repository
  • installation is under the /opt/remi tree
  • the Apache module, php55-php, is available, but of course, only one mod_php can be used (so you have to disable or uninstall any other, the one provided by the default "php" package still have priority)
  • the FPM service (php55-php-fpm) is available, it listens on default port 9000, so you have to change the configuration if you want to use various FPM services simultaneously.
  • the php55 command give a simple access to this new version, however the scl command is still the recommended way.
  • PECL extensions are also available.
  • only x86_64, no plan for other arch.
  • this collection is not compatible with RHSCL 1.1 (so you need to choose your provider and take all packages from the same place).

$ scl enable php55 'php -v'
PHP 5.5.16 (cli) (built: Sep  3 2014 08:55:14)

So Fedora 21 users are now able to simply run the 3 maintained versions of PHP simultaneously, 5.4 (SCL), 5.5 and 5.6 (system).

As always, your feedback is welcome, a SCL dedicated forum is open.
