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 nameserver 100.100.2.138 # 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
