Centos中怎么Yum安装php5.5、php5.6、php7.0多个版本？

1.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

2、设置yum源

Webtatic EL7 for CentOS/RHEL 7:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

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

Webtatic EL6 for CentOS/RHEL 6:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

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

Webtatic EL5.1 for CentOS/RHEL 5:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-5.noarch.rpm

rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm

如果想删除上面安装的包，重新安装

rpm -qa | grep webstatic

rpm -e 上面搜索到的包即可

3.运行yum install安装支持包

php5.5的版本

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

php5.6的版本

yum install php56w.x86_64 php56w-cli.x86_64 php56w-common.x86_64 php56w-gd.x86_64 php56w-ldap.x86_64 php56w-mbstring.x86_64 php56w-mcrypt.x86_64 php56w-mysql.x86_64 php56w-pdo.x86_64

php7.0的版本

yum install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64

4.安装PHP FPM

php5.5的版本：yum install php55w-fpm php55w-opcache

php5.6的版本：yum install php56w-fpm

php7.0的版本：yum install php70w-fpm

Zend Opcache 已经集成在了PHP 5.5里面，编译安装PHP5.5的时候加上–enable-opcache就行了。
