如何在 Ubuntu 上为 Apache2 配置子域？
我按照这些为 apache 配置子域的说明。我可以使用 http://localhost/test 访问子域，但无法通过 http://test.localhost 访问它。我怎样才能实现后者？
# /etc/apache2/sites-available/test.localhost
<VirtualHost *:80>
# Server name
ServerName test.localhost
# Document root
DocumentRoot /var/www/test/
# Custom log file locations
ErrorLog /var/www/test/logs/error.log
CustomLog /var/www/test/logs/access.log combined
</VirtualHost>
I followed these instructions to configure subdomains for apache. I can access the subdomain using http://localhost/test though I cannot access it via http://test.localhost. How can I realize the latter?
# /etc/apache2/sites-available/test.localhost
<VirtualHost *:80>
# Server name
ServerName test.localhost
# Document root
DocumentRoot /var/www/test/
# Custom log file locations
ErrorLog /var/www/test/logs/error.log
CustomLog /var/www/test/logs/access.log combined
</VirtualHost>

由于 Mark B 已经正确回答，问题是
/etc/hosts中的配置错误。正确的配置是：As Mark B already answered correctly the problem was a misconfiguration in
/etc/hosts. The correct configuration is:您链接到的博客文章（来自我的博客）指示设置一个 IP 为 127.0.0.2 的新 VirtualHost 元素，以便您可以轻松创建多个子域。
您使用 127.0.0.1 进行设置将非常适合一个子域，但如果您计划添加更多子域，我建议按照帖子中所述设置新的 VirtualHost 元素。
The blog post you linked to (from my blog) instructs to set up a new VirtualHost element with an ip of 127.0.0.2 so you can create multiple subdomains easily.
You're setup using 127.0.0.1 will work great for one subdomain, but if you plan on adding more, I'd suggest setting up the new VirtualHost elements as described in the post.
使用 apache tomcat 7 和 ubuntu 服务器时配置子域非常简单。

实际上子域需要时间来配置，因为我们使用 cPanel 添加它至少需要 2-3 天，并且然后配置server.xml并重新启动tomcat，我们就可以按预期运行它了。

Actually subdomain takes time to configure as we add it using cPanel at least 2-3 days and then configuring server.xml and restarting tomcat we can run it as expected.
