install postfixadmin in a subfolder of a domain in nginx - nginx

Question

I need to install postfixadmin as a subfolder of a domain hosted in nginx.
In other words, I'm trying to access postfixadmin using http://example.com/postfixadmin
Physically, the contents of the sites are stored this way:
example.com site in /var/www/example
Postfixadmin files in /var/www/postfixadmin
I've tried adding this within the server section of example.com:
location ~ /posfixadmin/ {
root /var/www;
index index.php;
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
The above works partially, php scripts are executed correctly, but css and image files found under /var/www/postfixadmin/css and /var/www/postfixadmin/images are not loaded.
I've checked at the generated html code and the links to css and image files in postfixadmin are called using relative paths, like this:
href="css/default.css"
I think nginx tries to get the css files from http://example.com/css instead of http://example.com/postfixadmin/css, that's why it's failing, I've tried something like this:
location /postfixadmin/css/ {
root /var/www/postfixadmin;
}
but the above doesn't work.
Any idea about how to fix this? Thanks in advance!

I know it's an old topic, but still: do not use "root" in a "location" block. Source: https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
This works for me at the moment with the current PostfixAdmin 3.2 (which moved all the public facing stuff into the "public" subdirectory). Mind that I have defined the fastcgi_pass elsewhere, so this bit is not directly applicable.
location /postfixadmin {
alias /usr/local/www/postfixadmin/public;
location ~ ^(.+\.php)(.*)$ {
fastcgi_pass php;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_read_timeout 180;
fastcgi_buffers 4 256k;
fastcgi_buffer_size 128k;
}
location ~ \.php {
include /usr/local/etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass php;
fastcgi_index index.php;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
