在 Apache 2.2.22 中，我尝试运行两个虚拟主机，它们具有两个 IP 地址和两个 SSL 证书。除了配置虚拟主机的文件之外，我没有在任何其他配置文件中监听端口或 NameVirtualHost。在实现此功能的过程中，我希望使用最少的代码。
在 sites-available 目录中我有 site1.com 配置文件：
NameVirtualHost 1.1.1.1:80
Listen 1.1.1.1:80
Listen 1.1.1.1:443
<VirtualHost 1.1.1.1:80>
ServerAdmin [email protected]
ServerName site1.com
ServerAlias www.site1.com
RewriteEngine On
RewriteCond %{SERVER_PORT} !443
RewriteRule (.*) https://www.site1.com/ [R]
</VirtualHost>
<VirtualHost 1.1.1.1:443>
ServerName site1.com
ServerAlias www.site1.com
DocumentRoot /home/j/site1/public
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/site1.com.crt
SSLCertificateKeyFile /etc/apache2/ssl/site1.com.key
SSLCertificateChainFile /etc/apache2/ssl/gd_bundle_site1.crt
LogLevel warn
ErrorLog /home/j/site1/log/error.log
CustomLog /home/j/site1/log/access.log combined
</VirtualHost>
如果 site1.com 是唯一启用的站点，则服务器可以正常启动。当我启用 site2.com 时，我遇到了麻烦。Sudo apachectl configtest结果为，Syntax OK但重新启动 apache 会导致(99)Cannot assign requested address: make_sock: could not bind to address 2.2.2.2:8080 no listening sockets available, shutting down Unable to open logs Action 'start' failed.以下是 site2.com 的内容：
NameVirtualHost 2.2.2.2:8080
Listen 2.2.2.2:8080
Listen 2.2.2.2:4430
<VirtualHost 2.2.2.2:8080>
ServerAdmin [email protected]
ServerName site2.com
ServerAlias www.site2.com
RewriteEngine On
RewriteCond %{SERVER_PORT} !4430
RewriteRule (.*) https://www.site2.com/ [R]
</VirtualHost>
<VirtualHost 2.2.2.2:4430>
ServerName site2.com
ServerAlias www.site2.com
DocumentRoot /home/j/site2/public
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/site2.com.crt

感谢您的帮助。

更新：
grep -r Listen /etc/apache2 除了上面提到的之外，没有对端口 8080 上的 Listen 进行任何引用。

根据下面 Jenny D 的建议，ifconfig -a 产生以下内容：

答案1
此错误可能是由于Listen针对同一 IP 地址/端口组合有两个指令而导致的。
由于您netstat没有看到端口 8080 上有任何监听，我强烈怀疑这是您的问题。
尝试grep -r Listen /etc/apache2找到它们。
答案2
难以置信。这是防火墙的问题。必须添加端口。
