我有一台为 localhost:8000 提供服务的机器，我想用 apache 对其进行反向代理。
我已设置/etc/apache2/sites-enabled/000-default.conf如下：
<VirtualHost *:*>
ProxyPreserveHost On
ProxyPass / http://real_address.net/
ProxyPassReverse / http://localhost:8000/
</VirtualHost>
（注：real_address 是我的实际域名，而不是 real_address）当我尝试访问我的域名时，它不起作用。我收到 502。从远程服务器读取时出错。
我究竟做错了什么？
