今天帮同事搭建环境时碰到yum更新出问题了，报如下错误：

YumRepo Error: All mirror URLs are not using ftp, http[s] orfile.

Eg. $releasever is not a valid release or hasntbeen released yet/

removing mirrorlist with no valid mirrors:/var/cache/yum/base/mirrorlist.txt

Error: Cannot retrieve repository metadata (repomd.xml) forrepository: base. Please verify its path and try again

从字面意思是看是不能正确连接到http或是ftp的真实地址上。

1.有可能是防火墙阻碍了出网http请求或是ftp请求，请检查网关防火墙。

2.有可能是dns不对，无法正常解析，换成8.8.4.4

3.系统取不到Release号

我这里碰到真正的原因是就是3，系统读取不到Release号。

正常一般可以看到版本号

# lsb_release -a LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.2 (Final) Release: 6.2 Codename: Final

但是同事的环境上确是，原因就不说了，又想骂人了，哎。

LSBVersion: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: n/a Description: n/a Release: n/a Codename: n/a

而/etc/yum.repos.d下的*.repo源文件中都是baseurl都是带变量的

baseurl=http://mirrors.163.com/centos/$releasever/contrib/$basearch/

所以yum去尝试读取xml文件自然失败了。

# wget http://mirrors.163.com/centos/%releasever/os/x86_64/repodata/repomd.xml --2013-01-24 10:50:10-- http://mirrors.163.com/centos/%releasever/os/x86_64/repodata/repomd.xml Resolving mirrors.163.com... 123.58.173.89, 123.58.173.106 Connecting to mirrors.163.com|123.58.173.89|:80... connected. HTTP request sent, awaiting response... 404 Not Found 2013-01-24 10:50:11 ERROR 404: Not Found.

所以需要修改*.repo源文件中将$releasever变量全替换成6即可正常yum了。

cat/etc/yum.repos.d/CentOS6-Base-163.repo # CentOS-Base.repo [base] name=CentOS-6 - Base - 163.com baseurl=http://mirrors.163.com/centos/6/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-6 - Updates - 163.com baseurl=http://mirrors.163.com/centos/6/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-6 - Extras - 163.com baseurl=http://mirrors.163.com/centos/6/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existingpackages [centosplus] name=CentOS-6 - Plus - 163.com baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #contrib - packages by Centos Users [contrib] name=CentOS-6 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

看看这次更新缓存就成功了。
