centos7默认自带的php5.4版本,因为系统需要，需要安装php5.6版本
设置源
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm #更新源
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
安装php5.6.x
yum remove php-common -y #移除系统自带的php-common
yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring #安装依赖包
php -v #版本变为5.6
安装php-fpm
yum install php56w-fpm.x86_64
systemctl restart php-fpm
systemctl enable php-frm
查看是否安装成功
ps -ef | grep php
netstat -anp | grep 9000
