yum install wget -y 提示 [Errno 256] No more mirrors to try.

ping www.baidu.com ,检查网络是否连通，如何出现Name or service not known，一般是DNS没有配置好

# ping www.baidu.com
#ping: www.baidu.com: Name or service not known

在/etc/resolv.conf配置本机的DNS

vim /etc/resolv.conf
nameserver 114.114.114.114
nameserver 8.8.8.8
systemctl restart network  #重启网络
ping www.baidu.com     #再次ping 可以ping通
yum install wget -y

Complete!

 

安装完成
