如何在PHP CGI上检查mod_rewrite [英] How to check for mod_rewrite on PHP CGI

问题描述

我在共享主机上，PHP却被当作CGI脚本安装，这就是我无法找到是否启用mod_rewrite的全部问题

Note: I don't have any root level access so i can't much do with Shell.

我尝试了以下方法:
1)在 phpinfo()中签到知道这是在PHP-CGI中寻找错误的地方.

2)我试图从apache_get_modules中获取它，而agi在PHP-CGI中不起作用:(
3)我尝试过:

if (strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false) {
    // mod_rewrite is enabled
}

它正在询问apache的路径，我没有此信息，SHELL无法回复我，$ _ SERVER没有任何信息.
4)我已经在.htaccess中使用RewriteEngine On进行了检查，此后我的网站抛出了500内部服务器错误，可能是由于RewriteEngine不存在，但我需要将此内容写给别人看.

任何机构都知道如何检查此操作.

谢谢

解决方案

使用PHP CGI，没有简单的方法来找出mod_rewrite在服务器上是否可用.

因此，您需要通过对服务器进行测试调用来找出它.您可以针对此方法使用以下步骤，

1. 在服务器上创建一个名为mod_rewrite_test的目录.

2. 使用以下代码在该目录中添加.htaccess文件

   <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /mod_rewrite_test RewriteRule .* mod_rewrite_test.txt </IfModule>

   a.第一行告诉apache仅在mod_rewrite可用时执行以下代码，
   b.第二行启用重写引擎，
   C.第三行设置重写来自DOCUMENT_ROOT
   的基本目录路径 d.第四行将mod_rewrite_test.txt文件的内容返回到发送到mod_rewrite_test目录的任何请求.

3. 在同一目录中创建一个名为mod_rewrite_test.txt的文件.在该文件中写入ok并保存.

4. 现在，在您的php脚本中使用CURL，调用类似于以下网址，

   http://www.your-domain.com/mod_rewrite_test/test.php 并检查响应.

   因此，根据我们的.htaccess代码，如果mod_rewrite处于活动状态并且可以在服务器上运行， 即使test.php文件不存在，它也会返回mod_rewrite_test.txt文件的内容，即ok.

   否则，它将返回404-找不到页面错误.

I am on shared host and PHP is inatalled as CGI script and that is all the problem i am not able to find whether mod_rewrite if enable or not

Note: I don't have any root level access so i can't much do with Shell.

I have tried the following :
1) checked in phpinfo() where i came to know about that this is the wrong place to look for in PHP-CGI.

2) I have tried getting it from apache_get_modules which agi does not work in PHP-CGI :(
3) I have tried :

if (strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false) {
    // mod_rewrite is enabled
}

which is asking for path to apache and i dont have this info SHELL cant reply to me and $_SERVER has nothing.
4) I have checked with RewriteEngine On in .htaccess and after this my site is throwing 500 Internal server error may be because of RewriteEngine is not there, but i need this is written to show someone.

Any body has any idea how to check get this DONE.

Thanks

解决方案

With PHP CGI there is no easy way to find out whether mod_rewrite is available or not on the server.

So, you need to find out it by making a test call to the server. You can use the following steps for this method,

1. Create a directory named mod_rewrite_test on the server.

2. Add .htaccess file in this directory with the following code,

   <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /mod_rewrite_test RewriteRule .* mod_rewrite_test.txt </IfModule>

   a. first line tells apache to execute the below code only if mod_rewrite is available,
   b. second line enables rewrite engine,
   c. third line sets rewrite base directory path which is from DOCUMENT_ROOT
   d. forth line returns the content of mod_rewrite_test.txt file to any request sent to mod_rewrite_test directory.

3. Create a file named mod_rewrite_test.txt in the same directory. Write ok in this file and save it.

4. Now, using CURL in your php script, call the URL similar to,

   http://www.your-domain.com/mod_rewrite_test/test.php and check the response.

   So, as per our .htaccess code, if mod_rewrite is active and working on the server, it will return the content of mod_rewrite_test.txt file i.e. ok even though the test.php file does not exists.

   Otherwise, it will return 404 - Page not found error.
