I am a new Nginx web server user. How do I redirect to a different domain using nginx (say example.org to example.com) permanently?
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:
server {
server_name .example.org;
return 301 $scheme://example.com$request_uri;
}
server {
server_name example.com;
# rest of config, if any goes below ... #
}
Finally, restart/reload your nginx server, type:
# nginx -t && nginx -s reloadHow 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
