您好我对服务器配置，apache和codeigniter相当新。我在我的ubuntu 16.04上安装了apache，在我的服务器的DocumentRoot中创建了一个html文件（index.html）（即var / www / html），只是为了检查它是否有效。当我进入＆＃34; localhost＆＃34;要在firefox中的url栏显示index.html文件（所以我认为它有效吗？）。但是当我尝试安装codeigniter时（通过将所有下载的codeigniter文件复制到指南中所述的我的服务器的DocumentRoot下的新目录（名为codeigniter））并转到localhost / codeigniter而不是页面上显示的welcome_message：< / p>

在玩codeigniter文件时，我注意到页面上显示的内容直接是文件var / www / html / codeigniter / index.php的内容 在第78行之后。我不认为我改变了任何文件的内容，所以我不知道为什么我会看到这个而不是welcome_message。
我还尝试创建另一个视图，通过创建必要的php文件来查看问题是否与welcome_message有关 在 controller 和 views 目录下，当我尝试去localhost / codeigniter / newview时，我发现404找不到错误。
如果你能提供帮助，我会很高兴的。提前致谢。

在Application / Config / Config.php
中你可以设置任何默认视图文件
$config['index_page'] = ''; or $config['index_page'] = 'welcome_message.php';
或者
您可以在application / config / routes.php
中设置默认控制器$route['default_controller'] = 'CONTROLLER Name/METHOD Name(optional)';
如果设置该默认控制器，它将在该方法中加载该方法和视图文件。所以你可以设置控制器和方法名称来查看你想要的页面。
