Centos 5.5不能使用yum

Centos 5.5不能使用yum的问题

以下报错信息：

[[e-mail] yum.repos.d]# yum search mysqlLoaded plugins: fastestmirror, securityLoading mirror speeds from cached hostfileYumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. Invalid release/removing mirrorlist with no valid mirrors: /var/cache/yum/base/mirrorlist.txtError: Cannot find a valid baseurl for repo: base

1.修改 vi /etc/yum.repos.d/CentOS-Base.repo ，用以下内容替换

#  # 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.

yum clean all

3.重新加载缓存

yum makecache
