NGINX rewriting rule for getting clean URL - wordpress

Question

What would be the nginx rewrite rule to redirect my wordpress permalink structure from /%category%/%postname%/ to /%postname%/?

Answer 1

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 php
upstream 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;
}
}
