letsencrypt是免费的新证书颁发机构
现在问题已经解决，我正在编辑这个问题，因为如果有人也遇到同样的问题，请检查cPanel 官方插件在：
参考：https://documentation.cpanel.net/display/CKB/The+Let%27s+Encrypt+Plugin
我想要安装在 cPanel 的服务器域上。
我已经关注了怎么运行的
$ git clone https://github.com/letsencrypt/letsencrypt
$ cd letsencrypt
$ ./letsencrypt-auto --help
但它不起作用

如果有人了解如何使用 apache 安装 SSL，那么您的建议对我以及全世界所有其他网站所有者都会非常有帮助。
答案1
从日志中可以看出：
- 你使用的是 python 2.6，他们认为这个版本不够可靠，所以给它贴上标签
very experimental - 您缺少该
python-virtualenv软件包，可能是因为它不适用于您的发行版
我猜你使用的是 RHEL6/centos6，所以你的 python 2.7 包被命名了python27*，并且lets-encrypt脚本还不够智能，无法解决这个问题。
