一、安装php7

apt-get install python-software-properties

apt-get install software-properties-common

add-apt-repository ppa:ondrej/php

apt-get update

apt-get install php7.0  --可以不安装

apt-get install php7.0-fpm

apt-get install php7.0-cli php7.0-common php7.0-curl php7.0-gd php7.0-mysql

php -v  --查看版本

php -m  --查看安装的模块

#启动php服务

service php7.0-fpm start

二、nginx支持php

修改/etc/php/7.0/fpm/pool.d/www.conf    

listen = /run/php/php7.0-fpm.sock修改为listen = 127.0.0.1:9000

nginx.conf添加如下：

location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
}
