問題

分類：工作

今天幫同事搭建環(huán)境時碰到y(tǒng)um更新出問題了，報如下錯誤：

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

從字面意思是看是不能正確連接到http或是ftp的真實地址上。

1.有可能是防火墻阻礙了出網(wǎng)http請求或是ftp請求，請檢查網(wǎng)關(guān)防火墻。

2.有可能是dns不對，無法正常解析，換成8.8.4.4

3.系統(tǒng)取不到Release號

我這里碰到真正的原因是就是3，系統(tǒng)讀取不到Release號。

正常一般可以看到版本號

?# 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

但是同事的環(huán)境上確是，原因就不說了，又想罵人了，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都是帶變量的

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

所以yum去嘗試讀取xml文件自然失敗了。

?# 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

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源文件中將$releasever變量全替換成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

看看這次更新緩存就成功了。
