无法在 CentOS 7 上安装 Let's Encrypt 证书

我正在尝试在 CentOS 7 上使用 Let's Encrypt 保护 Apache，将 Let's Encrypt SSL 证书安装到我的网站。

我的网络服务器是（包括版本）：Apache (cPanel)

我的托管提供商是：GoDaddy

点击此链接为此，STEP-1 和 STEP-2 成功了

据了解，我的 VPS 中没有设置防火墙

sudo yum install epel-release
sudo yum install httpd mod_ssl python-certbot-apache
sudo systemctl start httpd
systemctl status httpd
curl www.example.com ((Note: works))       
sudo certbot --apache -d example.com -d www.example.com

最后一个命令会生成错误，如下所示：

sudo: certbot: command not found

我尝试通过安装 certbot

sudo yum install certbot

并安装成功

Complete!

我再次尝试为我的域请求 SSL 证书。

   sudo certbot --apache -d example.com -d www.example.com

这次它回来了

注意：我用我的实际域名替换了 example.com

更新1

我尝试过

  sudo yum install python-certbot-apache

它正在返回

  --> Finished Dependency Resolution
  Error: Package: python2-certbot-apache-0.27.1-1.el7.noarch (epel)
       Requires: mod_ssl
  You could try using --skip-broken to work around the problem
   You could try running: rpm -Va --nofiles --nodigest

答案1

这样做有什么问题？：

sudo yum install mod_ssl

sudo a2enmod ssl

（然后重新启动apache）
