NGINX rewriting rule for getting clean URL

In summary, you need to let NGINX know that if that file doesn't exist, to not throw a 404 error, but rather call index.php. Wordpress is smart enough to parse the URL as parameters, and serve the correct page.

Add this snippet in your server configuration block:

location / {    try_files   $uri $uri/ /index.php?$args;}

Here is a complete example from nginx.org:

# Upstream to abstract backend connection(s) for phpupstream php {        server unix:/tmp/php-cgi.socket;        server 127.0.0.1:9000;}server {        ## Your website name goes here.        server_name domain.tld;        ## Your only path reference.        root /var/www/wordpress;        ## This should be in your http block and if it is, it's not needed here.        index index.php;        location = /favicon.ico {                log_not_found off;                access_log off;        }        location = /robots.txt {                allow all;                log_not_found off;                access_log off;        }        location / {                # This is cool because no php is touched for static content.                # include the "?$args" part so non-default permalinks doesn't break when using query string                try_files $uri $uri/ /index.php?$args;        }        location ~ \.php$ {                #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini                include fastcgi.conf;                fastcgi_intercept_errors on;                fastcgi_pass php;        }        location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {                expires max;                log_not_found off;        }}
