今天幫同事搭建環(huán)境時(shí)碰到y(tǒng)um更新出問題了，報(bào)如下錯(cuò)誤：
YumRepo Error: All mirror URLs are not using ftp, http[s] orfile.
?Eg. $releasever is not a valid release or hasntbeen released yet/
removing mirrorlist with no valid mirrors:/var/cache/yum/base/mirrorlist.txt
Error: Cannot retrieve repository metadata (repomd.xml) forrepository: base. Please verify its path and try again
從字面意思是看是不能正確連接到http或是ftp的真實(shí)地址上。
1.有可能是防火墻阻礙了出網(wǎng)http請(qǐng)求或是ftp請(qǐng)求，請(qǐng)檢查網(wǎng)關(guān)防火墻。
2.有可能是dns不對(duì)，無法正常解析，換成8.8.4.4
3.系統(tǒng)取不到Release號(hào)
我這里碰到真正的原因是就是3，系統(tǒng)讀取不到Release號(hào)。
正常一般可以看到版本號(hào)
| ?# lsb_release -a LSB Version:???:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description:???CentOS release 6.2 (Final) Release:???????6.2 Codename:??????Final |
但是同事的環(huán)境上確是，原因就不說了，又想罵人了，哎。
| ?LSBVersion:???:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: n/a Description:???n/a Release:???????n/a Codename:??????n/a |
而/etc/yum.repos.d下的*.repo源文件中都是baseurl都是帶變量的
baseurl=http://mirrors.163.com/centos/$releasever/contrib/$basearch/
所以yum去嘗試讀取xml文件自然失敗了。
| ?# wget http://mirrors.163.com/centos/%releasever/os/x86_64/repodata/repomd.xml --2013-01-24 10:50:10--? http://mirrors.163.com/centos/%releasever/os/x86_64/repodata/repomd.xml Resolving mirrors.163.com... 123.58.173.89, 123.58.173.106 Connecting to mirrors.163.com|123.58.173.89|:80... connected. HTTP request sent, awaiting response... 404 Not Found 2013-01-24 10:50:11 ERROR 404: Not Found. |
所以需要修改*.repo源文件中將$releasever變量全替換成6即可正常yum了。
| ? cat/etc/yum.repos.d/CentOS6-Base-163.repo #released updates #additional packages that may be useful #additional packages that extend functionality of existingpackages #contrib - packages by Centos Users |
看看這次更新緩存就成功了。
