以上 location 的配置是针对 phalcon 框架而言，下面是针对 symfony 应用的。

symfony.conf

server {
    listen 80;
    server_name symfony.com;
    root /home/www/symfony/web;

    location / {
        index index.html index.htm index.php;
        try_files $uri /app.php$is_args$args;
    }   

    # DEV
    location ~ ^/(app_dev|config)\.php(/|$) {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

    # PROD
    location ~ ^/app\.php(/|$) {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include        fastcgi_params;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

        # symfony.com/app.php/some-path
        # Remove the internal directive to allow URIs like this.
        #internal;
        }

    access_log logs/symfony.access.log;
}

小结：

多应用基于项目拆分的场景或思想，独立开发、独立部署，可以做到互不影响，如同前后端分离一样。

这里大家会发现，反向代理不仅可以简化多应用的部署，还能做到负载均衡，只需增加 upstream机器 就能横向扩展。

其实也完全可以 以大模块的方式整合成一个强大应用，从易维护上来讲更容易一点。两种方式都各有优势。
