Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: Updates-ambari-2.0.0. Please verify its path and try again

解决办法：resolve.conf中添加dns服务器

[root@test yum.repos.d]# more /etc/resolv.conf

# Generated by NetworkManager

# No nameservers found; try putting DNS servers into your

# ifcfg files in /etc/sysconfig/network-scripts like so:

#

# DNS1=xxx.xxx.xxx.xxx

# DNS2=xxx.xxx.xxx.xxx

# DOMAIN=lab.foo.com bar.foo.com
