为 Apache SSL 使用多个 CA 证书

Question

我有两个虚拟主机，使用两个证书。虽然以下 httpd.conf 文件未指明，但我正在使用 *.example.com 以及 *.sites.example.com，因此需要这两个证书。访问https://bla.sites.example.com/时，浏览器显示如下警告：

bla.sites.example.com uses an invalid security certificate.
The certificate is only valid for the following names: *.example.com, example.com
(Error code: ssl_error_bad_cert_domain)

如果我删除重定向到 www.example.com 的第一个 VirtualHost，我不会收到警告。

这是为什么，我应该如何为不同的 VirtualHosts 使用多个 CA 证书？

<VirtualHost *:443>
    ServerName example.com
    SSLEngine on
    SSLCipherSuite SSLv3:TLSv1:+HIGH:!SSLv2:!MD5:!MEDIUM:!LOW:!EXP:!ADH:!eNULL:!aNULL
    SSLCertificateKeyFile /etc/pki/tls/private/example_key.pem
    #Following certificate is good for example.com and *.example.com
    SSLCertificateFile /etc/pki/tls/certs/example_startssl_class2.crt
    SSLCertificateChainFile /etc/pki/tls/certs/sub.class2.server.ca.pem
    RewriteEngine on
    RewriteRule .* https://www.example.com%{REQUEST_URI} [NE,R,L]
</VirtualHost>

<VirtualHost *:443>
    ServerName example.com
    ServerAlias *.sites.example.com
    ErrorDocument 404 /error-404.html
    DocumentRoot /var/www/example/html_sites
    SSLEngine on
    SSLCipherSuite SSLv3:TLSv1:+HIGH:!SSLv2:!MD5:!MEDIUM:!LOW:!EXP:!ADH:!eNULL:!aNULL
    SSLCertificateKeyFile /etc/pki/tls/private/example_key.pem
    #Following certificate is good for example.com, sites.example.com and *.sites.example.com
    SSLCertificateFile /etc/pki/tls/certs/example_startssl_sites_class2.crt
    SSLCertificateChainFile /etc/pki/tls/certs/sub.class2.server.ca.pem
    <Directory "/var/www/example/html_sites">
        allow from all
        Options +Indexes
    </Directory>
</VirtualHost>

注意我在/etc/httpd/conf.d/ssl.conf中有如下设置：

#Following certificate is good for example.com and *.example.com
SSLCertificateFile /etc/pki/tls/certs/example_startssl_class2.crt
SSLCACertificateFile /etc/pki/tls/certs/example_startssl_class2.crt
SSLCertificateKeyFile /etc/pki/tls/private/example_key.pem
SSLCertificateChainFile /etc/pki/tls/certs/sub.class2.server.ca.pem

Answer 1

您的 VHOST 设置不正确。你们都指向 ServerName example.com

它们都应该具有不同的特定 ServerName 和不同的文档根目录。然后 apache 将知道将请求发送到正确的虚拟主机的位置，并且您不会收到该错误。

您可以在此处查看更多配置帮助。 Multiple Certs using SNI

因为它们是两个不同的证书，您的虚拟主机应该看起来像这样。

<VirtualHost *:443>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example/html_sites
    SSLEngine on
    SSLCipherSuite SSLv3:TLSv1:+HIGH:!SSLv2:!MD5:!MEDIUM:!LOW:!EXP:!ADH:!eNULL:!aNULL
    SSLCertificateKeyFile /etc/pki/tls/private/example_key.pem
    #Following certificate is good for example.com and *.example.com
    SSLCertificateFile /etc/pki/tls/certs/example_startssl_class2.crt
    SSLCertificateChainFile /etc/pki/tls/certs/sub.class2.server.ca.pem
    <Directory "/var/www/example/html_sites">
        ErrorDocument 404 /error-404.html
        allow from all
        Options +Indexes
        RewriteEngine on
        RewriteRule .* https://www.example.com%{REQUEST_URI} [NE,R,L]
    </Directory>
</VirtualHost>

<VirtualHost *:443>
    ServerName bla.sites.example.com
    ServerAlias *.sites.example.com
    DocumentRoot /var/www/example2/html_sites
    SSLEngine on
    SSLCipherSuite SSLv3:TLSv1:+HIGH:!SSLv2:!MD5:!MEDIUM:!LOW:!EXP:!ADH:!eNULL:!aNULL
    SSLCertificateKeyFile /etc/pki/tls/private/example_key.pem
    #Following certificate is good for example.com, sites.example.com and *.sites.example.com
    SSLCertificateFile /etc/pki/tls/certs/example_startssl_sites_class2.crt
    SSLCertificateChainFile /etc/pki/tls/certs/sub.class2.server.ca.pem
    <Directory "/var/www/example2/html_sites">
        allow from all
        Options +Indexes
    </Directory>
</VirtualHost>

还要记得在进行更改时重新启动 apache。
