如何在 Apache 中使用 SSL 配置多个子域？

Question

配置：

• Debian
• 阿帕奇2
• 通配符 SSL 用于：*.example.com
• 子域：a.example.com、b.example.com。
• 1个专用服务器
• 网站在 NodeJS (ProxyPass...)

现在，我可以让 a.example.com 工作。 但是我如何让 a.example.com 和 b.example.com 在同一台服务器上工作？

/etc/apache2/site-enable/a.example.com.conf
<VirtualHost  *:80>
  ServerName a.example.com
  Redirect permanent / https://a.example.com
</VirtualHost>
<VirtualHost  *:80>
  ServerName www.a.example.com
  Redirect permanent / https://a.example.com
</VirtualHost>
Listen 443

<VirtualHost *:443>
 ServerName a.example.com
 ServerAlias www.a.example.com

 ProxyRequests off
 LimitRequestLine  150000
 LimitRequestFieldSize 150000
 <Proxy *>
  Order deny,allow
  Allow from all
 </Proxy>

 <Location />
  ProxyPass http://localhost:4949/
  ProxyPassReverse http://localhost:4949/
 </Location>

 SSLEngine on
 SSLProtocol all -SSLv2 -SSLv3
 SSLCipherSuite ALL:!DH:!EXPORT:!RC4:+HIGH:+MEDIUM:!LOW:!aNULL:!eNULL

 SSLCertificateFile   /etc/ssl/2__.example.fr.crt
 SSLCertificateKeyFile  /root/XXXXXX.key
 SSLCertificateChainFile    /etc/ssl/1_root_bundle.crt 
</VirtualHost>

更新 --- 如果我尝试这个：

/etc/apache2/site-enable/b.example.com.conf
<VirtualHost  *:80>
ServerName b.example.com
Redirect permanent / https://b.example.com
</VirtualHost>
<VirtualHost  *:80>
ServerName www.b.example.com
Redirect permanent / https://b.example.com
/VirtualHost>

Listen 443

<VirtualHost *:443>
 ServerName b.example.com
 ServerAlias www.b.example.com

 ProxyRequests off
 LimitRequestLine  150000
 LimitRequestFieldSize 150000
 <Proxy *>
  Order deny,allow
  Allow from all
 </Proxy>

 <Location />
  ProxyPass http://localhost:6949/
  ProxyPassReverse http://localhost:6949/
 </Location>

 SSLEngine on
 SSLProtocol all -SSLv2 -SSLv3
 SSLCipherSuite ALL:!DH:!EXPORT:!RC4:+HIGH:+MEDIUM:!LOW:!aNULL:!eNULL

 SSLCertificateFile   /etc/ssl/2__.example.fr.crt
 SSLCertificateKeyFile  /root/XXXXXX.key
 SSLCertificateChainFile    /etc/ssl/1_root_bundle.crt 
</VirtualHost>

我得到这个

[....] Restarting web server: apache2[Thu Jul 21 14:58:01 2016] [warn] module passenger_module is already loaded, skipping

--- 更新

我在 b.exemple.com.conf 上删除了 Listen 443

但是现在，我有这个：

a.example.com ---> b.example.com
b.example.com ---> b.example.com

问题是当我尝试访问 a 时，我被重定向到 b

我在做什么错？

/etc/apache2/site-enable/b.example.com.conf
<VirtualHost  *:80>
ServerName b.example.com
Redirect permanent / https://b.example.com
</VirtualHost>
<VirtualHost  *:80>
ServerName www.b.example.com
Redirect permanent / https://b.example.com
/VirtualHost>

<VirtualHost *:443>
 ServerName b.example.com
 ServerAlias www.b.example.com

Answer 1

更改所有子域的通配符 (*.example.com) 的虚拟主机代码，要实现此功能，您的 SSL 证书应该是支持多个子域的通配符

在 apache httpd.conf或ssl.conf文件的<virtualhost>代码中更改/添加两行

 ServerName www.example.com
 ServerAlias *.example.com

例子：

a.example.com
b.example.com
WHATEVER_SUB-DOMAIN_TEXT.example.com
