apache goes to nginx, the code side USES $_SERVER[‘PATH_INFO’], pathinfo is not turned on for nginx by default. So we have to turn it on manually

1, url rewrite

location / {  // methods 1
 if (!-e $request_filename)
 {
 rewrite ^/(.*)$ /index.php/$1 last;
 break;
 }
}
location / {  // methods 2
 try_files $uri $uri/ /index.php$uri;
}

2, pathinfo Settings

location ~ .*\.(php|php5)(.*)?$ // Notice this, configuration override 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;
}

Note here that after location the regex is determined according to the url rewrite.
