localhost/codeigniter显示index.php而不是welcome\u message.php

您好，我对服务器配置、apache和codeigniter还比较陌生。我在我的Ubuntu16.04上安装了apache，在我服务器的DocumentRoot（即var/www/html）中创建了一个html文件（index.html），只是为了检查它是否工作。当我在firefox的url栏中输入“localhost”时，它会显示index.html文件（所以我认为它可以工作？）。但是，当我尝试安装codeigniter（通过将所有下载的codeigniter文件复制到指南中所述的服务器DocumentRoot下的新目录（名为codeigniter））并转到localhost/codeigniter而不是页面上显示的欢迎消息时：

在处理codeigniter文件时，我注意到页面上直接显示的是文件var/www/html/codeigniter/index.php的内容 在78号线之后。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看到的是这个而不是欢迎信息

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欢迎消息有关 在controller和views目录下，当我尝试转到localhost/codeigniter/newview时，我得到404notfound错误

如果你能帮忙，我会很高兴的。提前谢谢

在Application/Config/Config.php中

在这种情况下，您可以设置任何默认视图文件

$config['index_page'] = ''; or  $config['index_page'] = 'welcome_message.php';

或

您可以在application/config/routes.php中设置默认控制器

$route['default_controller'] = 'CONTROLLER Name/METHOD Name(optional)';

---

如果您设置默认控制器，它将加载该方法并在该方法中查看文件。所以您可以设置控制器和方法名称以查看所需的页面。

您已经安装了apache并对其进行了测试，但您确定已经安装了php吗？可能是服务器将php解析为标记并将其吐回给您。如果你在ubuntu 16.04上，这里有一个很好的指南，可以帮助你在Ryankozak上安装一个LAMP Stack@Ryankozak。但我不确定问题是不是php没有安装，还是在/etc/apache2/mods enabled/dir.conf中更改了index.php的优先级。不管怎样，它成功了。非常感谢你！
