Codeigniter页面在localhost上加载，但在服务器上加载404 [英] Codeigniter page loads on localhost but 404's on server

问题描述

如果我要访问：

http：// localhost / entry

我看到了我的测试页。如果我要访问：

I see my test page. If I go to:

http://examplesite.com/

我得到一个404页面。我不是说Codeigniter 404页面，而是默认的Apache页面。代码库是相同的。

I get a 404 page. And I don't mean the Codeigniter 404 page but the default apache one. The code bases are identical.

首页可以正常运行，但任何内部页面404都可以。这是我的根.htaccess文件的内容：

The homepage works fine but any inner pages 404. This is the contents of my root .htaccess file:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    # Removes access to the system folder by users. Additionally this will allow you to create a System.php controller, 'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    # When your application folder isn't in the system folder. This snippet prevents user access to the application folder. Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    # Checks to see if the user is attempting to access a valid file, such as an image or css document, if this isn't true it sends the request to index.php.
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

在通过phpinfo（）验证的服务器上启用了模块重写。我缺少什么吗？

Mod rewrite is enabled on the server verified with phpinfo(). Am I missing something?

推荐答案

当您看到Apache的 404 状态页面时而不是CodeIgniter的 404 ，mod_rewrite不处于活动状态。

When you see Apache's 404 status page instead of CodeIgniter's 404, mod_rewrite is not active.

phpinfo 仅告诉您是否已加载模块，而不是已配置正确地。如果 mod_rewrite 是活动的，则可以通过在< IfModule mod_rewrite.c> ...< / IfModule> 。启用后，您会收到 500 服务器错误。

phpinfo only tells you, if a module is loaded, not if it's configured properly. You can check reliably, if mod_rewrite is active, by adding garbage to your .htaccess inside <IfModule mod_rewrite.c>...</IfModule>. When it is active, you will get a 500 server error.

要使用 mod_rewrite .htaccess 文件， AllowOverride 和 选项 必须为相应的目录设置，例如

To use mod_rewrite in .htaccess files, AllowOverride and Options must be set for the appropriate directory, e.g.

AllowOverride FileInfo
Options +FollowSymLinks

甚至

AllowOverride All # default if <= 2.3.8
Options All # this is the default

---

不相关，但 ％{REQUEST_URI} 开头为斜线，因此前两个规则（带有这些 RewriteCond s）将永远不匹配。

---

Unrelated, but %{REQUEST_URI} starts with a slash, so the first two rules (with these RewriteConds) will never match.
