Apache rewrite rule

问题:

I want to redirect "http://localhost/b.html" --> "http://localhost/a.html" I tried RewriteRule for that. But somehow it is not working for me.

I am using apache2 and my httpd.conf contains:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule rewrite_module modules/mod_rewrite.so

RewriteEngine On
RewriteRule ^/b.html$ http://localhost/a.html

When I tri "http://localhost/a.html" It shows me the web page. But when I triend "http://localhost/b.html" apache2/error_log says "file does not exist: b.html" Does any setting missing to enable rewrite_module?

回答1:

The problem is in your RewriteRule. this should work:

RewriteEngine On
RewriteRule ^/b.html$ /a.html [L]

1. the rule match (^b.html$) must not include the starting slash. (this works in .htaccess, but not in server config)
2. the rewrite target should be a relative URI if possible (i.e. on the same host)
3. the rule should end with a directive "what to do" - in this case [L]eave processing (no more rules will be processed)

Have you checked whether in your Apache configuration file (most likely httpd.conf) the directive for the Alias or VirtualHost section:

AllowOverride All

I had the same problem of modrewrite not working because I had it off:

AllowOverride None

Good luck.

回答3:

Do you have it inside the virtualhost section?

<VirtualHost *:80>
    RewriteEngine On
    RewriteRule ^/b.html$ /a.html
</VirtualHost>

It works now. Had to do two things:

1. Change "AllowOverride None" in /etc/apache2/sites-available/default to "AllowOverride All".

2. Put the rewrite rule in /var/www/.htaccess instead of httpd.conf

I am not sure why it does not works in httpd.conf. But it works after doing the above two things.
