Sitemap Subfolder

Hi, I need configure sitemap with subfolder. See my configuration example:

server {
listen 80;

root /usr/share/nginx/html/example.com;
index index.php index.html;

server_name example.com www.example.com;


location ~ \.php$ {
try_files $uri =404;
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}


But the problematic site is example.com/subfolder

I make a test, configuring a new virtual host and adding the ip server and fake dns in my hosts file:

This setting works! But only at the site at the root. I tried adding the subfolder before / sitemap, but does not work!


server {
listen 80;

root /usr/share/nginx/html/example.com/subfolder;
index index.php index.html;

server_name example.com fake.example.com;

location ~ ([^/]*)sitemap(.*)\.x(m|s)l$ {
rewrite ^/sitemap\.xml$ /sitemap_index.xml permanent;
rewrite ^/([a-z]+)?-?sitemap\.xsl$ /index.php?xsl=$1 last;
rewrite ^/sitemap_index\.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?\.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
rewrite ^/news-sitemap\.xml$ /index.php?sitemap=wpseo_news last;
rewrite ^/locations\.kml$ /index.php?sitemap=wpseo_local_kml last;
rewrite ^/geo-sitemap\.xml$ /index.php?sitemap=wpseo_local last;
rewrite ^/video-sitemap\.xsl$ /index.php?xsl=video last;
}

location ~ \.php$ {
try_files $uri =404;
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}


}
