ubuntu 上的 codeigniter 问题答案

【问题描述】：

我在 Ubuntu 10 (LAMP) 上安装了 Codeigniter。我有一个 htaccess 文件：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /dort
#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 ^(.*)$ /dort/index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends
#the request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /dort/index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin
ErrorDocument 404 /index.php
</IfModule>

到目前为止，我们使用 IP 地址连接了远程服务器，我的基地位于一个名为 ‘dort’，所以我们习惯这样称呼它：http://some_ip/dort

现在我们将虚拟主机映射到 dort，所以我们称它为：http://demo.dort.com/，然后突然什么都没有了

除了登录页面 (index.php) 之外的工作。我在 config.php 中更改了 $config['base_url'] 但我

继续获取 404。

请帮忙:(

【解决方案1】：

你用过虚拟主机吗？

我有同样的问题并用这个解决

1) 在我的情况下创建虚拟主机是这样的：文件 /etc/apache2/sites-available/default

<VirtualHost *:80>
    ServerAdmin admin@email.com
    DocumentRoot /var/www/dort
    ServerName yourdomain.biz #this domain must be define tld info.
    ErrorLog /var/log/apache2/error_2.log
    <Directory /var/www/dort>
        Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Order allow,deny
                allow from all
                # Uncomment this directive is you want to see apache2's
                # default start page (in /apache2-default) when you go to /
                #RedirectMatch ^/$ /apache2-default/

    </Directory>

</VirtualHost>

2) 在文件 /etc/hosts 中设置主机

127.0.0.1   localhost
127.0.0.1   yourdomain.biz
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

3).htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    # Send admin URL's to the admin controller (then skips the rest of the redirect rules)
    RewriteCond %{REQUEST_URI} ^/admin(.*)
    RewriteRule ^(.*)$ /index.php/admin/$1 [L]    

    # Redirects any request thats not a file or directory through to the main controller
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /index.php/main/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
</IfModule>

4) 确保重启 apache 时不显示错误

 Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

5) 去浏览运行这个urlhttp://yourdomain.biz

以上解决方案对我有用。我只想强调一件事。确保您在 /etc/apache2/sites-available/default 的虚拟主机文件中具有 AllowOverride All 而不是 AllowOverride None
