[转载]PHP 5.6 on CentOS/RHEL 7.0 and 6.6 via Yum

https://webtatic.com/packages/php56/

PHP 5.6.5 has been released on PHP.net on 22nd January 2014, and is also available for CentOS/RHEL 6.5 at Webtatic via Yum.

PHP 5.6 adds new features such as:

constant scalar expressions
variadic functions
argument unpacking
exponentiation operator
support for large(>2GiB) file uploads
SSL/TLS improvements including peer verification by default
a new command line debugger called phpdbg

To see what else has been added, check out the What has changed in PHP 5.6.x.

To install, first you must add the Webtatic EL yum repository information corresponding to your CentOS/RHEL version to yum:

CentOS/RHEL 7.x:

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

CentOS/RHEL 6.x:

rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

Now you can install PHP 5.6 (along with an opcode cache) by doing:

yum install php56w php56w-opcache

If you would like to upgrade php to this version it is recommended that you first check that your system will support the upgrade, e.g. making sure any CPanel-like software can run after the upgrade.

Unless you know what you are doing, it is risky upgrading an existing system. It’s much safer to do this by provisioning a separate server to perform the upgrade as a fresh install instead.

If you know what you are doing, you can upgrade PHP by:

yum install yum-plugin-replace

 

yum replace --enablerepo=webtatic-testing php-common --replace-with=php56w-common

It will likely give you a message “WARNING: Unable to resolve all providers …”. This is normal, and you can continue by tying “y“. You will be given a chance to see what packages will be installed and removed before again being given a chance to confirm.

SAPIs – different runtime environments of PHP

mod_php NTS: (non-thread safety) Contained in the php56w package, this SAPI integrates into Apache Httpd 2.2.*. It is the standard SAPI for use with httpd prefork mpm (the default mode httpd is ran under. It is not thread-safe, but doesn’t need to be due to prefork not using threads. It’s located at /usr/lib[64]/httpd/modules/libphp5.so
cli: Contained in the php56w-cli package, this SAPI allows running scripts from the command-line, and also has a built-in web server for development-use. Located at /usr/bin/php
fpm: Contained in the php56w-fpm package, fpm (FastCGI Process Manager) is a scalable FastCGI process, which acts similar to how Httpd prefork mpm works managing it’s forks. Located at /usr/sbin/php-fpm, it is controlled using the /etc/init.d/php-fpm service script
phpdbg: Contained in the php56w-phpdbg package, phpdbg has the ability to debug scripts using breakpoints from the command-line, and also supports remote-debugging using an external Java client for remote communication.
embedded: Contained in the php56w-embedded package, this SAPI allows embedding PHP in other applications. It’s library is located at /usr/lib[64]/libphp5.so
cgi, fastcgi: Contained in the php56w-cli package, these SAPIs are not recommended for use, but are available where needed. They both exist in the binary at /usr/bin/php-cgi.
mod_php TS: (thread safety) Contained in the php56w package, this SAPI integrates into Apache Httpd 2.2.*. It is the standard SAPI for use with httpd worker mpm. It’s supposed to be thread-safe, but can’t guarantee to be, and certainly not under additional PHP extensions. It’s better to use FastCGI SAPIs than this one. It’s located at /usr/lib[64]/httpd/modules/libphp5-zts.so

Opcode Caches

The PHP distribution now comes with an opcode cache. This is the Zend Optimizer+ opcode cache, now known as the Zend OPcache extension. This extension is optional, so does not preclude you from using an alternate one.

Due to it being included in the PHP source distribution, it will be well maintained and more suitable for use while other Opcode cache’s are being updated over the coming months.

yum install php56w-opcache

error_reporting E_ALL now includes E_STRICT

As mentioned in the PHP 5.4 guide:

You may get a lot more errors coming out of your error logs if by default your error_reporting is set to E_ALL now without explicitly turning off E_STRICT. The default php.ini that comes with the PHP package turns this off by default, but if you are upgrading from an existing installation, your php.ini may not be updated, meaning this will likely be turned on.
