centos linux 提示cannot find a valid baseurl for repo:update错误
cannot find a valid baseurl for repo:update
when i want to
yum instal php
or yum install mysql-server
i get this error
cannot find a valid baseurl for repo:update
what's that meaning?
DNS is not working??
ping www.centos.org
no response then add ur DNS server to /etc/resolv.conf
出现这个错误是因为服务器的DNS没有开启，或者服务器不能连接互联网络，请检查LINUX centos服务器的网络连接配置，如果ping www.awzsr.com 有TTL返回值，在运行就可以不会出现这个centos linux 提示cannot find a valid baseurl for repo:update错误错误了
