Codeigniter 在尝试访问 index.php 时抛出 404

Code Igniter throwing 404 when trying to access index.php

我使用本教程安装了 Enginx,MySQL 和 PHP:https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-on-ubuntu-14-04

这是我的 /etc/nginx/sites-available/default 文件:

# You may add here your
# server {
#   ...
# }
# statements for each of your virtual hosts to this file

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.php index.html index.htm;

    # Make site accessible from http://localhost/
    server_name localhost;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }

    # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
    #location /RequestDenied {
    #   proxy_pass http://127.0.0.1:8080;

    #   # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    #
    #   # With php5-cgi alone:
    #   fastcgi_pass 127.0.0.1:9000;
    #   # With php5-fpm:
    #   fastcgi_pass unix:/var/run/php5-fpm.sock;
    #   fastcgi_index index.php;
    #   include fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root

我从这里下载了 CodeIgniter zip 文件夹:http://www.codeigniter.com/userguide3/installation/downloads.html 并将解压缩的文件夹(CodeIgniter-3.0.0 文件夹)放在 /usr/share/nginx/(请注意,对于 Nginx,已设置根目录到 root /usr/share/nginx/html;.. 不确定它是否有所作为)。

这是我的 config.php CodeIgniter:

$config['base_url'] = '127.0.0.1/';
$config['index_page'] = 'index.php';

现在,我正在尝试创建一个基本的静态页面(遵循本教程:http://www.codeigniter.com/userguide3/tutorial/static_pages.html)。

在我按照上面的步骤转到我的"Routing"部分后,它说:控制器现在正在运行!将浏览器指向 [your-site-url]index.php/pages/view 以查看您的页面。当您访问 index.php/pages/view/about 时,您会看到关于页面,同样包括页眉和页脚。

但是,当我转到 127.0.0.1/index.php 时,我得到一个 404(如果我转到 127.0.0.1/index.php/pages/view,我也会得到一个 404)。

我认为 /html/ 文件夹和 /CodeIgniter-3.0.0/ 文件夹位于同一位置可能与此有关:

/usr/share/nginx/html/
/usr/share/nginx/CodeIgniter-3.0.0/

我是 PHP 和 LEMP 的新手。我不确定还需要什么信息来解决问题。任何帮助表示赞赏。

编辑:这是我的 /usr/share/nginx/CodeIgniter-3.0.0/application/controllers/Pages.php:

<?php
class Pages extends CI_Controller {

    public function view($page = 'home') {

    if (! file_exists(APPPATH.'/views/pages/'.$page.'.php')) {
        show_404();
    }

    $data['title'] = ucfirst($page);
    $this->load->view('templates/header', $data);
    $this->load->view('pages/'.$page, $data);
    $this->load->view('templates/footer', $data);

    }

}

我有办法。共分两步:

步骤 1) 从

移动 CodeIgniter-3.0.0 文件夹
/usr/share/nginx/ 

/usr/share/nginx/html/

步骤 2) 更改

$config['base_url'] = '127.0.0.1/';

$config['base_url'] = 'http://localhost/CodeIgniter-3.0.0/';

现在,index.php出现了。
