升级到php7（详解）

一下方法经本人实践，真实有效

1、更换yum源

cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.bak
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS6-Base-163.repo CentOS-Base.repo
yum clean all 
yum makecache
yum update

2、检查当前的安装的php包

yum list installed | grep php
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm

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

3、运行yum install

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 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

注：如果想升级到5.6吧上面的55w换成56w就可以了。

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-mysql.x86_64 php70w-pdo.x86_64

4.安装PHP FPM

yum install php55w-fpm 
yum install php56w-fpm 
yum install php70w-fpm
注：如果想升级到5.6把上面的55w换成56w就可以了。
