启动用户态代理时出错：监听 tcp 0.0.0.0:7050：绑定：地址已在使用中答案

【问题标题】：Error starting userland proxy: listen tcp 0.0.0.0:7050: bind: address already in use启动用户态代理时出错：监听 tcp 0.0.0.0:7050：绑定：地址已在使用中

【问题描述】：

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

因为我是 Ubuntu 和 docker 的新手，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

【问题讨论】：

这通常是其他容器或主机进程已经使用该端口的错误。您是否有可以共享的docker run 命令或任何其他源代码；还是您只是想运行一个预打包的应用程序？
我正在关注srcmake.com/home/fabric的教程

标签： docker ubuntu proxy hyperledger-fabric userland

【解决方案1】：

好吧，首先对于任何类型的超级账本教程，你最好关注官方链接，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，重新运行网络正常，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
