我有一个私人的networking服务器，我有几个虚拟主机。 我知道，为每个单独的虚拟主机分配一个证书是不可能的，因为只有在SSL连接build立后，服务器才会发现哪个虚拟主机是被请求的。 但有可能有一个单一的SSL证书列出几个域名？ 或者至less是一个通配符域，如* .example.com。 如果是的话，我需要编写哪些Linux命令才能生成这样的自签名证书？
补充：澄清 – 我只有一个虚拟主机的IP地址。
以下内容适用于您：
cp /etc/ssl/openssl.cnf /tmp echo '[ subject_alt_name ]' >> /tmp/openssl.cnf echo 'subjectAltName = DNS:www.example.com, DNS:site1.example.com, DNS:site2.example.com' >> /tmp/openssl.cnf openssl req -x509 -nodes -newkey rsa:2048 \ -config /tmp/openssl.cnf \ -extensions subject_alt_name \ -keyout www.example.com.key \ -out www.example.com.pem \ -subj '/C=XX/ST=XXXX/L=XXXX/O=XXXX/OU=XXXX/CN=www.example.com/[email protected]' 结果：

如果你想请求而不是自签名，只需用-reqextsreplace-x509和-extensions即可。
使用domain.com作为CN创build一个证书，并在subjectAltName：dNSName names字段中创build* .domain.com 。
在openssl ，将其添加到扩展中：
subjectAltName = DNS:*.domain.com
为了扩大AlberT的答案：

您不必使用通配符域。 您可以列出所有需要的主机名作为主题名称，它应该适用于所有主stream浏览器。
首先，您可以为每个单独的虚拟主机分配一个证书，关键是为每个虚拟主机创build不同的私有IP地址（以及外部/公共IP地址，如果要使其成为全球可访问的）。
但是，如果您的虚拟主机只是* .example.com，那么您也可以分配通配符证书。
对于命令 – 谷歌有很多结果 – 我只是从这里举一个例子：
http://www.justinsamuel.com/2006/03/11/howto-create-a-self-signed-wildcard-ssl-certificate/
并确保input* .example.com作为通用名称。
