我怎样才能解决这个问题？
我正在使用另一个EC2实例的图像的Amazon EC2：

SSLCertificateFile: file '/etc/apache2/ssl/d288922d35efb1b0.crt' does not exist or is empty Action 'configtest' failed.
你错过了一个crt文件。 你应该去原始的ec2实例，find这个文件，然后SCP把它放到你最近的实例中。
从godaddy下载标准SSL证书后，我不得不更新sudo vi /etc/apache2/sites-enabled/000-default.conf的.crt和.key。
现在我得到：
~$ apache2ctl configtest Syntax OK
