nginx + tomcat + php配置问题

入口：nginx
java：tomcat跑在8181端口，配置两个host虚拟机
php：php-cgi（php-fpm）方式，监听9000端口。解析php
nginx代理tomcat： 配置一个server，绑定对应的域名，重点是proxy_pass http://127.0.0.1:8181
nginx解析php：配置两个server，分别绑定对应的域名，重点是

        location ~ \.php$ {
            include        fastcgi.conf;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
            fastcgi_pass   127.0.0.1:9000;
        }
