Apache2环境下Shopware6站点www重定向至非www失效求助

问题原因排查 #

1. 首先确认mod_rewrite模块已启用，执行命令：
   sudo a2enmod rewrite
2. 原配置中的RewriteRule正则匹配规则错误，仅匹配单个路径字符，导致重定向路径异常、多余斜杠等问题
3. 未同时覆盖HTTP 80端口和HTTPS 443端口的www请求场景
4. 浏览器旧重定向缓存导致测试结果异常

正确配置方案 #

1. 端口80 VirtualHost配置 #

所有HTTP请求直接跳转至HTTPS非www域名，减少二次跳转：

<VirtualHost *:80>
        ServerName vanparysbakery.emakers.be
        ServerAlias www.vanparysbakery.emakers.be
        RewriteEngine On
        RewriteRule ^(.*)$ https://vanparysbakery.emakers.be/$1 [L,R=301,NE]
        ServerSignature Off
</VirtualHost>

2. 端口443 VirtualHost配置 #

单独处理HTTPS下的www域名请求跳转：

<VirtualHost *:443>
        Protocols h2 h2c http/1.1
        LoadModule ssl_module /usr/lib64/apache2-prefork/mod_ssl.so
        DocumentRoot /var/www/bakery/public
        ServerName vanparysbakery.emakers.be
        ServerAlias www.vanparysbakery.emakers.be
        <Directory /var/www/bakery/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride All
                Require all granted
        </Directory>
        SSLEngine on
        SSLProtocol all -SSLv2 -SSLv3
        SSLCipherSuite HIGH:!aNULL:!MD5:!ADH:!DH:!RC4
        SSLHonorCipherOrder on
        Include /etc/letsencrypt/options-ssl-apache.conf
        SSLCertificateFile /etc/letsencrypt/live/vanparysbakery.emakers.be/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/vanparysbakery.emakers.be/privkey.pem

        # HTTPS下www跳转非www规则
        RewriteEngine On
        RewriteCond %{HTTP_HOST} ^www\.vanparysbakery\.emakers\.be [NC]
        RewriteRule ^(.*)$ https://vanparysbakery.emakers.be/$1 [L,R=301,NE]
</VirtualHost>

生效步骤 #

1. 验证配置语法正确：sudo apache2ctl configtest
2. 重启Apache服务：sudo systemctl restart apache2
3. 测试时使用无痕浏览器模式，或清除浏览器缓存、本地DNS缓存，避免旧的重定向规则缓存影响测试结果。

建议将重定向规则统一放在VirtualHost配置中，优先级高于站点目录下的.htaccess，可避免Shopware自带的.htaccess规则覆盖自定义重定向逻辑。
