我正在 Linux 上设置 Hyperledger Fabric 专用网络，并在运行 ./byfn.sh 时收到消息

因为我是 Ubuntu 和 docker 的新手，所以我认为需要更改端口才能解决问题，但是，我不知道这样做。任何帮助，将不胜感激。

alaa@ubuntu:~/fabric-samples/first-network$ sudo netstat -pna | grep 7050
tcp6       0      0 :::7050                   :::*                    LISTEN      3682/docker-proxy

做了一个 netstat 来检查端口及其 docker-proxy

alaa@ubuntu:~/fabric-samples/first-network$ sudo ./byfn.sh up
Starting with channel 'mychannel' and CLI timeout of '10' seconds and CLI     delay of '3' seconds

好吧，首先对于任何类型的超级账本教程，你最好按照官方链接，因为大多数其他来源也来自那个：https ://hyperledger-fabric.readthedocs.io/en/release-1.4/

其次，关闭网络，停止并删除所有正在运行的和以前的容器，重新启动 docker，重新运行网络，应该可以正常工作：

$./byfn.sh down
$docker ps -qa|xargs docker rm
$sudo systemctl daemon-reload
$sudo systemctl restart docker
$cd....fabric-samples/first-network
$./byfn.sh -m generate
$./byfn.sh -m up
