You need to use HttpRewriteModule module to change URI using regular expressions (PCRE), and to redirect and select configuration depending on variables.
rewrite directive
This directive changes URI in accordance with the regular expression and the replacement string. Directives are carried out in order of appearance in the configuration file. You can use this directive in the following context:
- server
- if
- location
Nginx 301 rewrite syntax
The syntax is:
rewrite regex replacement [ flag ]
Flags can be any of the following:
- last – completes processing of current rewrite directives and restarts the process (including rewriting) with a search for a match on the URI from all available locations.
- break – completes processing of current rewrite directives and non-rewrite processing continues within the current location block only.
- redirect – returns temporary redirect with code 302; it is used if the substituting line begins with http://
- permanent – returns permanent redirect with code 301
Example: Redirect to a different domain with nginx
In this example, redirect all traffic as follows:
From: | To: |
example.org | example.com |
example.org/foo.html | example.com/foo.html |
example.org/show.php?arg=value | example.com/show.php?arg=value |
example.org/dir1/dir2/bar.cgi | example.com//dir1/dir2/bar.cgi |
Edit nginx.conf or your virtual host config and update server context as follows:
server { server_name .example.org; rewrite ^ http://example.com$request_uri? permanent; # rest of config, if any goes below ... # }
Finally, restart/reload your nginx server, type:
# nginx -t && nginx -s reload
How do I test and verify HTTP 301 redirect?
You need to use curl command:
$ curl -I http://example.org/
$ curl -I http://example.org/foo/bar.html
Sample outputs:
HTTP/1.1 301 Moved Permanently Server: nginx Date: Mon, 18 Nov 2013 12:29:08 GMT Connection: keep-alive Keep-Alive: timeout=60 Location: http://example.com/foo/bar.html Vary: Accept-Encoding X-Galaxy: Andromeda-2
Normally, you should use separate server block with ‘return’ directive, instead of ‘rewrite’ directive inside of main server block, for redirects

Good point. I appreciate your post.
Good!

Excellent was looking for this tutorial.
hi how can i forward any domain comming in (+subdomain) on http to https ?
so i don’t have to redirect for every singel domain
i will catch the https later in to different configs but i would only need one port 80 config since they all do the same
Sir how can i achieve 301 redirect using htaccess and also enable gzip compression
