Docker化CodeIgniter应用跳转页面出现Apache 404错误求助

CodeIgniter Docker化后非首页404问题排查与解决

问题情况

  • 已完成基于PHP(CodeIgniter框架)和MySQL的应用Docker化部署
  • 首页http://172.18.0.4/welcome可正常访问
  • 访问其他页面(如http://172.18.0.4/welcome/contact)时触发404错误:

Not Found The requested URL was not found on this server. Apache/2.4.38 (Debian) Server at localhost Port 80

  • 该应用在XAMPP环境下所有页面运行正常,尝试修改.htaccess和routes.php后问题未解决

已修改的配置文件

.htaccess文件

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

修改后的routes.php

$route['default_controller'] = 'welcome';
$route['tentang'] = 'welcome/tentang';
$route['pelajaran'] = 'welcome/pelajaran';
$route['kontak'] = 'welcome/kontak';
$route['guru'] = 'welcome/guru';
$route['admin'] = 'welcome/admin';
$route['404_override'] = '';
$route['translate_uri_dashes'] = false;

原routes.php

$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = false;

解决步骤

1. 启用Apache Rewrite模块

Docker的Apache镜像默认未开启rewrite模块,需在Dockerfile中添加以下命令开启:

RUN a2enmod rewrite

执行后重新构建镜像并启动容器。

2. 配置Apache虚拟主机允许.htaccess生效

修改Apache虚拟主机配置(如000-default.conf),在站点目录的<Directory>块中设置允许覆盖:

<Directory /var/www/html>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Require all granted
</Directory>

如果使用Docker,可通过Dockerfile将自定义配置文件复制到容器:

COPY ./000-default.conf /etc/apache2/sites-available/000-default.conf

3. 调整.htaccess的Rewrite规则格式

部分Apache版本不兼容index.php/$1的写法,改为以下格式:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [QSA,L]

4. 修正CodeIgniter的base_url配置

检查application/config/config.php中的$config['base_url'],设置为容器的访问地址:

$config['base_url'] = 'http://172.18.0.4/';

也可以用动态方式避免硬编码:

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

5. 检查容器内文件权限

确保Apache用户(www-data)拥有应用目录的读取权限,在Dockerfile中添加:

RUN chown -R www-data:www-data /var/www/html
RUN chmod -R 755 /var/www/html
