How to make a 301 redirect for the entire site from http and www to https without www?

Question

Nginx

Friends, we need help. How to make a 301 redirect for the entire site and its folders in .htaccess:
Redirect example below:
http://www.site.ru --> https://site.ru
Thanks in advance to everyone who helps with this problem! :)

Answer 1

if ($http_host != "site.ru") { rewrite ^ $scheme://site.ru$request_uri? permanent; }
if ($scheme != "https") { rewrite ^ https://$http_host$request_uri? permanent;}

You can also make a separate virtual host for http and redirect from it according to this rule
And similarly make a separate virtual host for www and redirect there like this
I will explain the difference in approaches, if there are separate virtual hosts it will be more optimal. After all, if is checked every time it is opened, wasting resources, and if redirects are stuffed into virtual hosts, resources are not wasted)

Answer 2

Add the following code in the .htaccess file:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^www.site.ru$ [NC]
RewriteRule ^(.*)$ http://site.ru/$1 [R=301,L]

Answer 3

Versatile and suitable for any project. Edit as there is a redirect to https://www., if the server is not a test one and not a local one.

# -- FORCE HTTPS
<IfModule mod_rewrite.c>
  RewriteEngine On

  RewriteCond %{HTTP_HOST} ^test. [NC]
  RewriteCond %{HTTP_HOST} \.loc$ [NC]
  RewriteCond %{HTTPS} =on [OR]
  RewriteCond %{HTTP:X-Forwarded-Proto} https
  RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,QSA]

  RewriteCond %{HTTP_HOST} ^test. [NC]
  RewriteCond %{HTTP_HOST} \.loc$ [NC]
  RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
  RewriteRule .* http://%1/%{REQUEST_URI} [R=301,L,QSA]

  RewriteCond %{HTTP_HOST} !^test. [NC]
  RewriteCond %{HTTP_HOST} !\.loc$ [NC]
  RewriteCond %{HTTP_HOST} !^www\. [NC]
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP:X-Forwarded-Proto} !https
  RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L,QSA]

  RewriteCond %{HTTP_HOST} !^test. [NC]
  RewriteCond %{HTTP_HOST} !\.loc$ [NC]
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP:X-Forwarded-Proto} !https
  RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,QSA]
</IfModule>
