letsencrypt-auto 确实不起作用
letsencrypt-auto certonly does'nt work
无论我将哪个命令与 ./letsencrypt-auto 一起使用，结果总是与 blew 相同，我是不是遗漏了什么。
这是 ./letsencrypt-auto certonly 上的输出。
[root@tipsycore letsencrypt]# ./letsencrypt-auto certonly

您使用的 LetsEncrypt 客户端 运行ning 需要 Python 2.7 或更高版本。您已安装 Python 2.6。我有一个博客 post 描述了我解决这个问题的方法：https://thelastcicada.com/solving-the-python-2-6-issue-for-letencrypt-on-centos-6。下面我将进一步详细介绍并总结我的解决方案。
我将从这个问题和你的 letsencrypt-auto 的输出假设你正在 运行ning CentOS 6 或类似的基于 RHEL6 的操作系统。这一点很重要，因为 CentOS 6 上的系统工具都是基于 Python 2.6（尤其是 yum），因此您的系统无法安全升级到 Python 2.6。 CentOS 7 没有这个问题，并且打包了更新版本的Python。
要在 CentOS 6 上解决此问题，您可以 运行 letsencrypt-auto --debug，如错误消息中所述，但这只允许您 运行 实验性 Python 2.6 代码尚未得到很好的支持。或者，您可以使用软件集在 CentOS 6 上安装 Python 2.7，在它自己的环境中，可以 运行 与 Python 2.6 并不会弄乱您系统的默认 Python 安装。
基本步骤是：
yum install centos-release-SCL 安装软件集合包yum install python27 安装 Python 2.7scl enable python27 "/root/letsencrypt/letsencrypt-auto certonly --agree-tos --webroot --webroot-path /var/www/html/mywebsite.com -d mywebsite.com" 到 运行 LetsEncrypt 客户端通过软件集合使用 Python 2.7 版本。传递给 letsencrypt-auto 的标志是我在请求 SSL 证书以与 Nginx 一起安装时使用的典型标志——您的配置可能会有所不同。
希望这对您有所帮助，祝您好运！
