VMware虚拟机CentOS6.3出现yum安装出错

frcd

yum安装时出现


Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
or
14: PYCURL ERROR 6 - "Couldn't resolvehost 'mirrorlist.centos.org'"
or
[Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"
or
removing mirrorlist with no valid mirrors: //var/cache/yum/fedora/mirrorlist.txt
Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

可能是yum源出问题，或者网连不上。

1、先试试网络能连上不，可能ping得通wget没结果

wget www.google.com
如果连不上，先检查网络

2、改yum配置，这里改为163的源

cd /etc/yum.repos.d
[iyunv@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
[iyunv@localhost yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.bak
将CentOS6-Base-163.repo的内容复制到CentOS-Base.repo

注意将里面的$releasever 换成Centos的版本6

如下：





# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
