CentOS6.8升级PHP到7.0

参考：https://webtatic.com/packages/php70/

1、停止nginx、mysqld、php-fpm

#service nginx stop
#service mysqld stop
#service php-fpm stop

2、卸载现有php php-fpm
#rpm -qa|grep php

删除之前安装的php版本 (yum install 安装)
#rpm -e php56w-cli-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-xml-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-odbc-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-fpm-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-pecl-igbinary-2.0.1-1.w6.x86_64 --nodeps
#rpm -e php56w-common-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-pdo-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-process-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-gd-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-pear-1.10.4-1.w6.noarch --nodeps
#rpm -e php56w-opcache-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-ldap-5.6.32-1.w6.x86_64 --nodeps
#rpm -e php56w-pecl-redis-3.1.4-1.w6.x86_64 --nodeps
#rpm -e php56w-mysql-5.6.32-1.w6.x86_64 --nodeps

3、更新源

#rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
#rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
4、查看及安装PHP7.0

查看php版本列表
#yum list php*

安装php及相关软件

#yum install php70w.x86_64 php70w-opcache.x86_64 php70w-pdo.x86_64 php70w-fpm.x86_64 php70w-mysql.x86_64 \
php70w-gd.x86_64 libjpeg* php70w-ldap.x86_64 php70w-odbc.x86_64 php70w-pear.noarch php70w-xml.x86_64 \
php70w-xmlrpc.x86_64 php70w-mbstring.x86_64 php70w-bcmath.x86_64 php-mhash php70w-pecl-redis.x86_64

启动php-fpm

#service php-fpm start

查看php版本

#php -v
PHP 7.0.25 (cli) (built: Oct 29 2017 18:22:34) ( NTS )

PHP7.0直观感觉快好多，建议大家都升级到PHP7
