从 CentOS 5.7 更新至 CentOS 5.8

在某些 CentOS 5.7 机器上，‘yum list updates’ 不显示适用于 5.8 的 centos-release。这是怎么回事？

机器A

[dnd@one:~]$ yum list updates | grep centos-release
[dnd@one:~]$ cat /etc/redhat-release 
CentOS release 5.7 (Final)

机器B

[root@l-e0 ~]# yum list updates | grep centos-release 
centos-release.x86_64                 10:5-8.el5.centos                 base    
centos-release-notes.x86_64           5.8-0                             base  
[root@l-e0 ~]# cat /etc/redhat-release 
CentOS release 5.7 (Final)

5.8 刚刚发布。我引用 CentOS 邮件列表的内容：

I am populating the CentOS mirrors with the 5.8 release at this time.

We are very close to releasing 5.8, just doing some extended testing,
which I fully expect it to pass based on the fixes rolled in.

I expect that CentOS-5.8 will be released to the external mirrors in
less than 24 hours and released to the 24-48 hours after that.
[...]
So, look for 5.8 to be released in the next 24-72 hours.

根据您当前首选的镜像重新同步的频率和时间，新的二进制文件在整个镜像网络中传播时可能会有延迟；恰好在正确的时间重新同步的镜像将会拥有它们，而等待下一次重新同步的镜像则不会拥有它们。

如果这让您感到烦恼，我发现yum clean all通常会允许我随机选择不同的镜像，并且可能已准备好更新。

如果它真的打扰你了，你应该看看列出的镜子CentOS 镜像列表，找到一个靠近您并且具有更新的一个，然后将其硬连线到您的/etc/yum.repos.d/CentOS-Base.repo。

或者您可以再等一两天！
