httpd 2.4连接php-fpm

php-fpm参数修改

默认php-fpm监听在127.0.0.1接口上，修改listen = 192.168.99.150:9000，可以监听在指定网卡上。
默认php-fpm仅允许127.0.0.1连接，修改listen.allowed_clients = 192.168.99.150，可允许指定主机连接。

第一种方法(SetHandler)

追加到/etc/httpd/conf/httpd.conf最后

<FilesMatch .php$>
setHandler "proxy:fcgi://127.0.0.1:9000"
</FilesMatch>

第二种方法(ProxyPassMatch)

虚拟主机内配置

<VirtualHost *:80>
    ServerName www.a.com
    DocumentRoot /var/www/html/
    ProxyRequests Off
    ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1
</VirtualHost>

<VirtualHost *:80>
    ServerName www.a.com
    DocumentRoot /var/www/html
    <IfModule mpm_event_module>
        ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://192.168.99.150:9000/var/www/html/$1
    </IfModule>
</VirtualHost>
