Apache LetsEncrypt问题

Question

我试图在Linode服务器上建立一个带有HTTPS的网站。它在HTTP上工作，但在HTTPS上不起作用。

我尝试使用Certbot为HTTPS配置域。

root@mailer9:/etc/apache2/sites-enabled# sudo certbot --apache
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache

Which names would you like to activate HTTPS for?

1: mailer9.com
2: www.mailer9.com

Cert not yet due for renewal

You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

Your existing certificate has been successfully renewed, and the new certificate
has been installed.

The new certificate covers the following domains: https://mailer9.com and
https://www.mailer9.com

You should test your configuration at:
https://www.ssllabs.com/ssltest/analyze.html?d=mailer9.com
https://www.ssllabs.com/ssltest/analyze.html?d=www.mailer9.com

root@mailer9:/etc/apache2/sites-enabled# 

它说这个东西应该可以正常工作，但是它不能在HTTPS模式下工作。

我在启用站点的目录中看到两个VH文件。

root@mailer9:/etc/apache2/sites-enabled# cat mailer9.com.conf 
# domain: mailer9.com
# public: /var/www/html/mailer9.com/public_html/

<VirtualHost *:80>
  # Admin email, Server Name (domain name), and any aliases
  ServerAdmin xxx@yy.com
  ServerName  mailer9.com
  ServerAlias www.mailer9.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.html index.php
  DocumentRoot /var/www/html/mailer9.com/public_html
  # Log file locations
  LogLevel warn
  ErrorLog  /var/www/html/mailer9.com/log/error.log
  CustomLog /var/www/html/mailer9.com/log/access.log combined

#RewriteEngine on
#RewriteCond %{SERVER_NAME} =mailer9.com [OR]
#RewriteCond %{SERVER_NAME} =www.mailer9.com
#RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

另一个HTTPS，由Certbot自动生成。

root@mailer9:/etc/apache2/sites-enabled# cat mailer9.com-le-ssl.conf 
<IfModule mod_ssl.c>
<VirtualHost *:443>
  # Admin email, Server Name (domain name), and any aliases
  ServerAdmin xxx@yy.com
  ServerName  mailer9.com
  ServerAlias www.mailer9.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.html index.php
  DocumentRoot /var/www/html/mailer9.com/public_html
  # Log file locations
  LogLevel warn
  ErrorLog  /var/www/html/mailer9.com/log/error.log
  CustomLog /var/www/html/mailer9.com/log/access.log combined


SSLEngine on
Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/mailer9.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/mailer9.com/privkey.pem
</VirtualHost>
</IfModule>
root@mailer9:/etc/apache2/sites-enabled# 

但是，如果我访问http://mailer9.com/，它就可以正常工作。但是如果我去https://mailer9.com/，页面就不会加载。我对如何解决这个问题一无所知，在我看来一切都很好。

Apache模块命令apachectl -M显示ssl_module已加载。

这是由ufw防火墙引起的。我增加了端口443，它修复了它。

sudo ufw allow 443/tcp
