Upgrading php from 5.4 to 5.5

Skyuser · Jun 18, 2014

Hello everyone!
What's the better way to upgrade php from 5.4 to 5.5 with saving all modules?
Using yum list installed | grep php and manually installing everything?

What repo are you using for upgrading? remi?

Donno why but remi shows me " nothing to upgrade".

You need to edit the remi repo to enable the PHP5.5 group.

Thanks, i noticed it few minutes ago. My old rem.repo had not lines of code with [remi-php55].
Last question - do i need to rebuild imagick from 5.4 to 5.5?

Yes, because the directory where it's expecting the .so file to be will have changed.

Ok, now update is working. But what with built in opcache in 5.5. Do i need smth to intall it or just everything "in box" with this update?

It will create a file with the settings in: /etc/php.d/opcache.ini

enable it by changing setting : opcache.enable=1

and then tweak the rest of the settings to suite your needs.

Thanks. How should i enable it in XenForo?
First - delete APC line in config.php

Code:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['backend'] = 'Apc';

And after that?

You don't need to anything to make zendopcache work with XenForo. It will automatically cache the PHP files. You need to install Memcached to be able to use the backend cache with PHP5.5 or APCu

And what about libmemcached? Is it better?

Yes, install them both.

memcached.x86_64
libmemcached.x86_64
php-pecl-memcached.x86_64

Do i need to install the memcache PECL Extension for PHP or memcached?
According to this article - http://www.ipserverone.info/control-panel/how-to-install-memcached-and-libmemcached/ i need memcache.

Memcached :

This is from when I upgraded @Brogan s server the other night:

@MattW My server running under nginx 1.4.7 pagespeed + Apache 2.2.25, MySQL 5.5.x, php 5.4 APC. I want to update nginx to 1.6.0, MySQL to MariDB 10 and php 5.5 with op + memcached. Hosting - Digitaloceab 1GB ram plan.
Will be there any speed boost? CPU usage in high load time - 15-17% and Ram - 220 mb.

Are you using a control panel on the VPS?

No. Everything was built on fresh-installed CentOS 6.4 x32 from repos/sources

Any reason why you are using Apache + nginx, and not just using nginx?

You mean nginx + php-fpm?
I know nothing about php-fpm

Yes, so I presume you are using nginx as a reverse proxy to apache from the above. php5-fpm is quite easy to set up, so you could totally do away with apache, and use nginx+php-fpm
