查看php版本

检查当前安装的php包

yum list installed | grep php

yum clean all

删除安装的PHP包

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-mysql.x86_64 php-odbc.x86_64 php-pdo.x86_64 php-process.x86_64 php-xml.x86_64 php-xmlrpc.x86_64

升级包

Centos 5.X

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

CentOs 6.x

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

CentOs 7.X

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

然后删除

rpm -e “输入上面搜索到的包即可”
