用apache2重写网址

Question

I'm experimenting with CodeIgniter PHP framework, this framework works like:

http://localhost:7777/~dhalsim/ci/index.php/blog

So, I tried to remove index.php part from there. So far I do these:

1. make $config['index_page'] = "index.php"; to $config['index_page'] = "";

2. make $config['uri_protocol'] = "REQUEST_URI"; from $config['uri_protocol'] = "AUTO";

3. enable apache mod_rewrite by " a2enmod rewrite "

4. put a .htaccess file to /ci directory:

    RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php/$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] 

5. And of course restart apache server

Here is my apache logs with these configurations:

Here is the result in Firefox:

404 Not Found:
The requested URL /index.php was not found on this server.

So, what should I do (or where am I wrong) to get work these URLs? http://localhost:7777/~dhalsim/ci/blog/ instead of http://localhost:7777/~dhalsim/ci/index.php/blog/

Answer 1

Here is how i resolve it:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|flash|css|js|robots\.txt|downloads)

RewriteRule ^(.*)$ /index.php/$1 [L]

Then in the config.php file

/*
|--------------------------------------------------------------------------
| Base Site URL
|--------------------------------------------------------------------------
|
| URL to your CodeIgniter root. Typically this will be your base URL,
| WITH a trailing slash:
|
|   http://example.com/
|
*/
$config['base_url'] = "http://localhost:7777/~dhalsim/ci/";

/*
|--------------------------------------------------------------------------
| Index File
|--------------------------------------------------------------------------
|
| Typically this will be your index.php file, unless you've renamed it to
| something else. If you are using mod_rewrite to remove the page set this
| variable so that it is blank.
|
*/
$config['index_page'] = "";

UPDATE

In the routes.php file:

//Point to default controller
$route['default_controller']    = "site/home"; //Set to your controller

// Point to the right controller
$routing_array = array(
            'blog' => 'site/blog',
        ); // set to your blog controler

Answer 2

Use the following Rewrite Rule:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(.*)$ /index.php/$1 [NC,L]

In order for this to work you should setup your CodeIgniter app on a different port or use /etc/hosts to give it a simple Vhost ( 127.0.0.1 ci and http://ci:7777/ with Apache set to use the ci vhost.). Then you can set the base url to / and not worry about it. Otherwise you're going to have to deal with confusing directory issues and mod_rewrite.
