Hyperledger Fabric安装问题-阿里云环境问题

如果是在阿里云机器上部署fabric ，在e2e_cli 启动网络时，遇到以下错误

用户则需要修改 /etc/resolv.conf 配置，将 options timeout:2 attempts:3 rotate single-request-reopen 这一行内容注释掉

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 100.100.2.136

# options timeout:2 attempts:3 rotate single-request-reopen

这个解决方法是从 https://yq.aliyun.com/articles/238940 看到的，作者试过，给增加 GODEBUG=netdns=go 环境变量也不好使，只会又出现以下问题

而真正能够彻底解决的方法，就是将 /etc/resolv.conf 注释掉  options timeout:2 attempts:3 rotate single-request-reopen ，就能够正常启动了
