How to set location with extension in NGINX server

Question

I'm new with NGINX server and I was wondering how to set something like this.

location phpmyadmin \.(gif|jpg|png)$ {
    root /usr/share/phpmyadmin;
}

example above fails at server restart.

Thanks for all answers.

UPDATE:

location ~* .(gif|jpg|jpeg|png|ico|wmv|3gp|avi|mpg|mpeg|mp4|flv|mp3|mid|js|css|html|htm|wml)$ {
    root /home/safeftp/www/public_html;
}

location ~ "phpmyadmin \.(gif|jpg|png)$" {
    root /usr/share/phpmyadmin;
}

Answer 1

If you want to use regex, use ~ (for case-sensitive matching) or ~* (for case-insensitive matching). Your location block should look like this:

location ~ "phpmyadmin \.(gif|jpg|png)$" {
    root /usr/share/phpmyadmin;
}
