阿里云ECS之Centos7下载文件出现”wget: unable to resolve host address”

wget https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
--2020-07-06 22:01:10--  https://dev.mysql.com/get/mysql80-community-release-el7-3.noarch.rpm
Resolving dev.mysql.com (dev.mysql.com)... failed: Name or service not known.
wget: unable to resolve host address ‘dev.mysql.com’

  

下载yum镜像的时候出现wget失灵的情况,
wget默认安装的
分析是DNS的问题
解决办法:

vi /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
