Hyperledger farbric 安装调试大坑

今天在调试hyperledger时，执行

github.com/hyperledger/fabric/examples/e2e_cli/network_setup.sh up

报错：

!!!!!!!!!!!!!!! Channel creation failed !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

网上搜了大半天，有人说

在/etc/hosts 里改 127.0.0.1 orderer.example.com , 

再修改 base/peer-base.yaml，添加 volumes：

volumes:

-/etc/hosts:/etc/hosts

我试了一下发现没用，后来仔细看了错误：

tcp: lookup orderer.example.com on 127.0.0.11:53: read udp 127.0.0.1:50875->127.0.0.11:53

想到127.0.0.11:53 这是docker 的embedded DNS 的 nameserver，推测有可能是docker引起的；

于是果断 systemctl restart docker

systemctl restart docker
network_setup.sh restart
