我正在尝试在我的 Ubuntu 14 服务器上安装 SSL 证书（使用 apache 2）。由于某种原因，端口 443 似乎已关闭
我安装并启用了 ssl
/etc/apache2/ports.conf如下：
Listen 80
#<IfModule ssl_module>
# Listen 443
#</IfModule>
<IfModule mod_ssl.c>
Listen 443
NameVirtualHost 92.243.16.14:443
</IfModule>
<IfModule mod_gnutls.c>
Listen 443
</IfModule>

答案1
我不太了解ufw，但在这种情况下，我认为它对交通完全无效INPUT，因为实施它的规则来自后一条规则DROP（链中的第五条规则INPUT）。从链中后面规则的数据包计数可以看出，INPUT没有数据包能够到达任何一条应该将流量发送到链的规则ufw-（我推测这些规则旨在实施ufw策略）。
如果你
iptables -I INPUT 5 -p tcp --dport 443 -j ACCEPT
这应该会打开您的 HTTPS 端口。我将让它在重启后保持不变留给您，因为它依赖于实现。
