我的应用程序中出现此错误:
Call From master/192.168.X.X to localhost:11111 failed on connection exception: java.net.ConnectException: Connection refused
ssh 确实失败了:
[user@master API_test]$ ssh localhost -p 11111
ssh: connect to host localhost port 11111: Connection refused
然后我在防火墙中打开它:
[user@master test]$ sudo iptables -L
.......
ACCEPT tcp -- anywhere anywhere tcp dpt:11111 ctstate NEW
但 nmap 仍然没有显示该端口已打开:
[user@master API_test]$ nmap master
Starting Nmap 6.40 ( http://nmap.org ) at 2018-01-19 06:00 PST
Nmap scan report for master (192.168.X.X)
Host is up (0.00049s latency).
Not shown: 998 closed ports
PORT STATE SERVICE
22/tcp open ssh
111/tcp open rpcbind
Nmap done: 1 IP address (1 host up) scanned in 0.06 seconds
我怎样才能解决这个问题?
答案1
您正在尝试连接端口11111
,但是您已111111
在 iptables 中打开。
11111 != 111111
修复 iptables 以打开正确的端口。
