Question

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

由于我是Ubuntu和docker的新手，因此我认为需要更改端口才能解决此问题，但是，我对此一无所知。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

使用netstat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

首先，对于任何一种超级账本教程，您最好遵循官方链接，因为大多数其他来源也来自该来源：https://hyperledger-fabric.readthedocs.io/en/release-1.4/

第二，关闭网络，停止并删除所有正在运行的容器，重启docker，重新正常运行网络，

$./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

启动Userland代理时出错：监听tcp 0.0.0.0:7050：绑定：地址已在使用中
