How to make a redirect in nginx?

Question

Nginx

all addresses that end in /index should be redirected to the same URL only without index, for example:
site.ru/new/items/index ->> site.ru/new/items
site.ru/new/categories/index ->> site.ru/new/categories
I only had enough for

location ~* /(index)(/?).* {
     rewrite  ^ <что то тут надо написать> permanent;
}

Answer 1

You can put it directly in the server block without adding location.

rewrite ^/index$ / permanent;
rewrite ^(.+)/index$ $1 permanent;

Can be combined into one rule.
rewrite ^/((.+)/)?index$ /$2 permanent;
