NGINX 下的 ECMALL 重写

[ZDW111]

相关环境：NGINX PHP
要把根目录下的www.aaa.com/index.php?app=search&keyword=主题
重写为：www.aaa.com/主题
if ($args ~* keyword=(.) ) {
rewrite ^/(.)$ http://$host/$arg_keyword? break;
}

可捕捉到相关网页，但404报错。如果采用try_files过滤掉404，则始终显示首页，地址栏显示www.aaa.com/主题

相关配置：
location ~ .php$ {
try_files $uri = 404;
fastcgi_pass unix:/dev/shm/php.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_cache ngx_fcgi_cache;
fastcgi_cache_valid 200 302 1h;
fastcgi_cache_valid 301 1d;
fastcgi_cache_valid any 1m;
fastcgi_cache_min_uses 1;
fastcgi_cache_use_stale error timeout invalid_header http_500;
fastcgi_cache_key http://$host$request_uri;
expires 2d;
}
等大牛啦。。。
