  解决：

   yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/o/oniguruma-5.9.5-3.el7.x86_64.rpm
   yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/o/oniguruma-devel-5.9.5-3.el7.x86_64.rpm
  

编译安装：

make && make install

添加命令到sbin中便于后期访问fpm

cp /opt/php/sbin/php-fpm /sbin/

生成标准配置

进入到etc目录，执行命令：

cp php-fpm.conf.default php-fpm.conf
cp php-fpm.d/www.conf.default php-fpm.d/www.conf

启动：

php-fpm -y /opt/php/etc/php-fpm.conf -R

检测php是否安装成功

一、在Nginx服务器的访问地址下建立一个index.php文件，文件内容如下。

二、在nginx.conf文件的server块儿中添加如下代码

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;
    }

三、在浏览器中访问该文件，如果能访问到phpinfo即安装php成功。

卸载php

（1）查询已经安装了的mysql包

#rpm –qa|grep php

（2）使用yum完全卸载

# yum remove 查询出来的依赖文件

（3）手工删除所创建的目录及文件

#rm –rf /opt/php
#rm /etc/php.d

（4）手工删除所创建的软链接
