CentOS6安裝新版本PHP

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

如下是CentOS 7.0的源
yum install epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

使用yum list命令查看可安裝的包
yum list --enablerepo=remi --enablerepo=remi-php56 | grep php

安裝PHP5.5的命令
yum install php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-ldap.x86_64 php55w-mbstring.x86_64 php55w-mcrypt.x86_64 php55w-mysql.x86_64 php55w-pdo.x86_64

yum源配置好了，下一步就安裝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

安裝PHP7的命令

安裝PHP FPM
yum install php55w-fpm
yum install php56w-fpm
yum install php70w-fpm
