apache往nginx去转，代码端用到了$_SERVER['PATH_INFO']，对于nginx默认是不开启pathinfo的。所以我们就要手动开启
1，url重写
location / { //方法1
if (!-e $request_filename)
{
rewrite ^/(.*)$ /index.php/$1 last;
break;
}
}
location / { //方法2
try_files $uri $uri/ /index.php$uri;
}
2，pathinfo设置
location ~ .*\.(php|php5)(.*)?$ //注意这块，配置重写的url
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi.conf;
}
这块要注意，location后正则要根据重写的url来决定。
