鉴于Centos 默认yum源的php版本太低了，手动编译安装又有点一些麻烦，那么如何采用Yum安装的方案安装最新版呢。
一、检查当前安装的PHP包
yum list installed | grep php
如果有安装的PHP包，先删除他们
yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_64
二、配置yum源
- 追加CentOS 6.5的epel及remi源。
# rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
- CentOS 7.0的源。
# yum install epel-release
# rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
- 使用yum list命令查看可安装的包(Packege)。
# yum list --enablerepo=remi --enablerepo=remi-php56 | grep php
三、安装PHP5.6.x
- yum源配置好了，下一步就安装PHP5.6
# yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof
- 用PHP命令查看版本。
# php --version
PHP 5.6.0 (cli) (built: Sep 3 2014 19:51:31)

四、安装PHP-fpm
yum install --enablerepo=remi --enablerepo=remi-php56 php-fpm
