创建channel时sudo ./network.sh up createChannel
出现错误
Error: Post "https://localhost:7053/participation/v1/channels": read tcp 127.0.0.1:44780->127.0.0.1:7053: read: connection reset by peer
Channel creation failed
解决方法
1.切换到：/go/src/github.com/hyperledger/fabric/scripts$目录下
sudo chmod +x fabric-samples
2.然后切换到：/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-network$
输入：sudo ./network.sh down
3.最后重新进行一下之前的过程
sudo ./network.sh up
sudo ./network.sh up createChannel
注意：一定要有sudo,否者容易出现Failed to generate certificates... 的错误
