nginx 根据网址进行不同反向代理方法

应用场景，win下面根据不同的网址代理到不同的php.exe

虚拟配置文件

# vhost/baidu.com.confserver {    listen 80;    listen 443 ssl;    server_name local.baidu.com www.baidu.com test.baidu.com;    root d:/website/baidu.com/src/public;    #root d:/website/baidu.com/src;    index index.html index.htm index.php;    ssl on;    ssl_certificate     d:/website/ssl/www.crt;     ssl_certificate_key d:/website/ssl/www.com.key;     ssl_session_cache    shared:SSL:10m;    ssl_session_timeout  10m;    ssl_protocols  SSLv2 SSLv3 TLSv1;    ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;    ssl_prefer_server_ciphers   on;    set $pass_to php_pool_pc ;    set $log_upstream 0;    if (!-e $request_filename) {        rewrite  ^/(.*)$  /index.php?_route_=$1  last;        break;    }    if ( $request_uri ~ ^$ ) {        set $pass_to php_pool ;    }    if ( $query_string ~ route=journal2 ) {        set $pass_to php_pool_pc2 ;    }    if ( $query_string ~ route=catalog) {        set $pass_to php_pool_pc3 ;    }    if ( $query_string ~ "route=catalog/product" ) {        set $pass_to php_pool_pc_admin ;    }    if ( $request_uri ~ ^/admin ) {        set $pass_to php_pool_pc_admin ;    }    location ~ \.php$ {        set $log_upstream 1;        add_header X-PASS-TO "$pass_to" ;        fastcgi_pass   $pass_to;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;        include        fastcgi_params;    }       access_log logs/pc-upstream.log upstream_log if=$log_upstream;    access_log logs/pc.log main;}

这算是一个特别蛋疼的解决方案，因为 win下面没有php-fpm，自动按需进行启动新进程。如果php特别稀烂的时候，就无法形容了。

• 新增了 add_header X-PASS-TO 为了方便调试
• 注意 set $pass_to php_pool_pc; 必须在 rewrite 之前，否则会报错 $pass_to 为空 500。
