错误启动Userland代理:听TCP 0.0.0.0:7050:bind:已使用的地址

Question

我在Linux上设置了一个HyperLeDger Fabric网络，并在运行时收到消息。/byfn.shup

由于我是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，我对此不知道。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HyperLeDger教程，您最好遵循官方链接，cos大多数其他来源也从该链接中获取：https：//https：//hyperledger-fabric。readthedocs.io/en/release-1.4/

其次，放下网络，停止＆amp;删除所有运行的容器，重新启动docker，正确重新运行网络，应正常工作：

$./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
