PHP是我们设置的组件，它将处理代码以显示动态内容。它可以运行脚本，连接到我们的MySQL数据库以获取信息，并将处理的内容传递到我们的Web服务器以显示。
PHP-FPM（PHP FastCGI Process Manager的简称，意思是 “PHP FastCGI进程管理器” ）是用于管理PHP进程池的软件，用于接收和处理来自Web服务器（例如nginx）的请求。PHP-FPM软件会创建一个主进程（通常以操作系统中根用户的身份运行），控制何时以及如何把HTTP请求转发给一个或多个子进程处理。PHP-FPM主进程还控制着什么时候创建（处理Web应用更多的流量）和销毁（子进程运行时间太久或不再需要了）PHP子进程。PHP-FPM进程池中的每个进程存在的时间都比单个HTTP请求长，可以处理10，50，100，500或更多的HTTP请求。
如果之前有安装，请先卸载，卸载请参考mysql卸载
本文安装PHP7.1版本，最新版最好办法是源码安装，请自行摸索
rpm安装php7.1相应的yum源，主要是下面两句命令
一、php7.1 yum 源
rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

四、查看安装PHP版本
[root@localhost ~]# php -v

六、启动php-fpm
[root@localhost ~]# systemctl start php-fpm
七、设置开机自启动（和前面mysql一样的）
[root@localhost ~]# systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
八、验证是否加入开机启动列表
[root@localhost ~]# systemctl list-unit-files
...
...
php-fpm.service enabled
...
九、查看安装路径
[root@localhost ~]# ps -ef | grep php
