修改文件后，情况yum源缓存：

yum clean all

此外还可以：

yum clean all

rm -f /var/lib/rpm/__db*

rpm –rebuilddb

yum update

试了试不行，干脆把fastestmirror禁掉解决了：

vi /etc/yum/pluginconf.d/fastestmirror.conf

enabled=1改成0

附上fastestmirror插件介绍：

使用yum可以简化系统软件更新的工作。为了保证更新的持续进行，通常都会提供多个mirror（镜像）地址供下载使用，但由于存在地域问题，从不同的镜 像下载速度差异很大。选择从适合的镜像下载软件包，会极大的影响更新速度。

以CentOS为例，可使用一个叫fastestmirror的插件，让yum 在更新时先根据ping值进行判断，然后从最快响应的地址下载。

yum --disableplugin=fastestmirror update

重新安装插件，正确
