这里空间服务商使用的是cPanel,不知道和这个有没有关系,我发现问如何开通https,对方说:每月2刀从他们那里买个专用(delicated)IP,然后再弄个证书(certificate)。
另开了一篇: 免费HTTPS(SSL)证书
cPanel提供的SSL/TLS Manager:
The SSL/TLS Manager will allow you to generate ssl certificates, signing requests, and keys. These are all parts of using SSL to secure your website. SSL allows you to secure pages on your site so that information such as logins, credit card numbers, etc are sent encrypted instead of plain text. It is important to secure your site's login areas, shopping areas, and other pages where sensitive information could be sent over the web.
1,Private Keys (KEY)
2,Certificate Signing Requests (CSR)
3,Certificates (CRT)
应该是可以自行产生SSL证书。
