我似乎无法让节点加入集群。

端口似乎已关闭(从节点(：
telnet 10.0.2.15 6443
Trying 10.0.2.15...
telnet: Unable to connect to remote host: Connection refused
在主服务器上：
telnet 10.0.2.15 6443
Trying 10.0.2.15...
Connected to 10.0.2.15.
Escape character is '^]'.
^CConnection closed by foreign host.
这可能是什么原因？
两台机器都是虚拟机，10.02.15 是 NAT IP - 这对两台机器都是相同的(它们是独立的(......
叹息。。。
如果对其他人有帮助：
iptables -t raw -A OUTPUT -p tcp --dport 6443 -j TRACE
iptables -t raw -A PREROUTING -p tcp --dport 6443 -j TRACE
tail -f /var/log/kern.log
如果您在 VM 上运行(例如使用流浪者和虚拟盒子(，请使用流浪者文件中使用的私有 IP 运行 init 命令。因此，如果您在节点上使用 join 命令，它能够访问它，否则不会。
语法：kubeadm init --apiserver-advertise-address=private-ip-address
示例：kubeadm init --apiserver-advertise-address=192.168.33.50
