Question

我需要一些帮助，我正在尝试在CentOS 5.9中安装yum update但我收到错误

> Loaded plugins: fastestmirror, kmod Loading mirror speeds from cached
> hostfile YumRepo Error: All mirror URLs are not using ftp, http[s] or
> file.  Eg. Invalid release/ removing mirrorlist with no valid mirrors:

请帮我解决这个问题

更新CentOS-Base.repo的内容

   [base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
exclude=redhat-logos php53*

#released updates
[updates]
name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

#contrib - packages by Centos Users
[contrib]

#mirrorlist=http://mirrorlist.centos.org/?release=5$releasever&arch=$basearch&repo=contrib

提前谢谢。

Answer 1

这是因为Centos 5已被弃用，需要手动更新Base repo文件以将所有内容指向Centos保险库。

备份你的/etc/yum.repos.d/Centos-Base.repo

替换为以下内容将让您重新开始：

$file = Get-Content .\router.txt | Out-String
$ints = $file | Select-String -Pattern "(?s)\ninterface [etfg][^!]+!" -AllMatches | foreach {$_.Matches.Value}
foreach ($line in $ints.split("!")) { 
    if ($line -match 'maximum\s*([0-9]+)') {
        $allowedMacs = $matches[1]
        if ($allowedMacs -gt ($line | Select-String "sticky [\d\w]" -AllMatches).Matches.Count) {
            write-host "Violation!"
        } else {
            write-host "No Violation!"
        }
    }
}

Answer 2

这可能是由两种可能性引起的。

<强> 1。 Repo太老了，无法找到

根据您的centos版本，我试图通过link找到操作系统。从自述文件中获取此信息。

不推荐使用此目录（及CentOS版本）。对于普通用户，       你应该在路径中使用/ 5 /而不是/5.9/。请参阅此FAQ       关于CentOS发布计划：

https://wiki.centos.org/FAQ/General

如果你知道自己在做什么，并且绝对想留在5.9       级别，转到http://vault.centos.org/获取包裹。请记住，5.9不再获得任何更新

在此链接中，建议您通过其他link查找旧版本。因此，您需要修改 CentOS-Base.repo 。

将所有http://mirror.centos.org/centos/***替换为http://vault.centos.org/***。

例如：

Original: baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
New:      baseurl=http://vault.centos.org/$releasever/os/$basearch/

<强> 2。网络问题

可以访问mirrorlist server。

$ ping mirrorlist.centos.org

如果您可能遇到以下错误消息。

ping: unknown host mirrorlist.centos.org

要解决此问题，请在resolv.conf中添加有效的名称服务器（如果您不是root用户，请使用sudo）

$ echo nameserver 8.8.8.8 > /etc/resolv.conf

错误：找不到repo：base的有效baseurl
