Apache Ubuntu 14.04.1多个SSL证书错误

我在我的Ubuntu web服务器上设置了两个网站，在获得两个SSL证书以正常工作时遇到了一些问题。一开始我确实有一个可以自己工作，但是，现在我无法成功地重新启动Apache

尝试重新启动Apache时出错

 * Restarting web server apache2
 * The apache2 configtest failed.
Output of config test was:

/etc/apache2/ports.conf的输出

# If you just change the port or add more ports here, you will likely also

#如果您只是在此处更改端口或添加更多端口，您也可能

听80
