活动主机上的codeigniter内部服务器错误

Question

我已经在public_html主文件夹中部署了一个使用CodeIgniter的网站(http://www.myexample.com)。该项目可在localhost上完美运行。为了从URL中删除index.php，它具有以下.htaccess：

RewriteEngine on
RewriteCond $1 !^(index\.php|public|\.txt) 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1

但是，当我尝试访问网站时，出现内部服务器错误：

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@its.org.pk to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

我已经应用了不同的.htaccess文件，但是得到了相同的错误。

Answer 1

迁移到现场服务器时，我最常做的是如下
第一.htaccess

<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,
#previously this would not have been possible.
#'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
#Submitted by: Fabdrol
#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>

然后是数据库的用户名和密码
application / config / database.php

$db['default'] = array(
'dsn'   => '',
'hostname' => 'localhost',
'username' => 'DATABASE_USERNAME',//database username here
'password' => 'DATABASE_PASSWORD',//database password here
'database' => 'DATABASE_NAME',//database name here
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);

然后在配置文件中 application / config / config.php

$config['base_url'] = 'http://example.com/';

如果仍然出现错误提示无法连接，请尝试验证数据库用户名，名称和密码，然后尝试更改数据库密码，以确保其正确的

UPDATE
检查文件权限，并确保它644和文件夹权限为755
Also check php，mysql版本和确保php版本为atlease 5.6或更高，并检查框架的服务器要求。
