获取并解压 PHP 源代码
wget http://cn2.php.net/distributions/php-5.6.37.tar.gz
tar zxf php-5.6.37.tar.gz
cd php-5.6.37为了防止编译出错安装依赖包

make && make install修改配置文件
cp /root/php-5.6.37/php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
ln -s /usr/local/php/sbin/php-fpm /usr/local/sbin/php-fpm（创建php-fpm启动命令）
[root@MySql etc]# cat php-fpm.conf
[global]
[www]
user = nginx(与nginx配置文件保持一致。我nginx中user是“nginx”)
group = nginx(同上)
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3然后启动 php-fpm 服务
php-fpm配置 Nginx 使其支持 PHP 应用
修改默认的 location 块，使其支持 .php 文件：
location / {
root html;
index index.php index.html index.htm;
}下一步配置来保证对于 .php 文件的请求将被传送到后端的 PHP-FPM 模块， 取消默认的 PHP 配置块的注释，并修改为下面的内容：
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;
} 重载nginx
\usr\local\nginx\sbin\nginx -s reload创建PHP测试文件
打开浏览器，访问 相应IP地址，将会显示 phpinfo() 
注：
nginx+php运行原理
nginx本身不能处理PHP，它只是个web服务器，当接收到请求后，如果是php请求，则发给php解释器处理，并把结果返回给客户端。
nginx一般是把请求发fastcgi（php-fpm就是其中的一种）管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx
同样php-fpm程序也如同nginx一样，需要监听端口，并且有master和worker进程。worker进程直接管理每一个php进程
