Nginx wordpress rewrite
From KOP KB
First example here is for the main root directory
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
This example is for sites that are in subfolders from the web root of the domain.
location /path/to/wordpress/ {
try_files $uri $uri/ /path/to/wordpress/index.php$is_args$args;
}
