从CentOS5框安装CentOS6？

我试图从我的CentOS 5主机上build立一个新的CentOS 6虚拟机，但似乎这些版本之间有一些基本的变化：

$ rpm -ivh --nodeps --nodigest --ignorearch --ignoreos --force --root=/mnt centos-release-6-0.el6.centos.5.i686.rpm warning: centos-release-6-0.el6.centos.5.i686.rpm: Header V3 RSA/SHA256 signature: NOKEY, key ID c105b9de Preparing... ########################################### [100%] 1:centos-release ########################################### [100%] error: unpacking of archive failed: cpio: Bad magic $ rpm --version RPM version 4.4.2.3

这些版本之间RPM的神奇数量是否改变？我如何解决这个问题？

编辑（澄清）：

我不想升级现有的机器。我正在尝试使用yum –installroot = / mnt groupinstall核心来创build新的安装。为了得到一个工作configuration，第一步是安装包含yum repoconfiguration的release rpm。

不能这样做，AFAIK：RPM中的坏魔法是最less的问题。

总之：没有推荐的RHEL5-> RHEL6升级path，因此没有Centos5-> 6。我尝试了一下这个方向（我自己有大量的C5服务器），但决定不这么做。

考虑到5> 6转换相当于Fedora核心6> 12转换，但在yum中没有预升级支持。所以你可以想象，popup一个FC7 DVD，开机

selinux = 0 upgradeany

漂洗，并以FC8 … FC11结束与CentOS6结束。祝你好运 – 说到我自己的机器，我会感到惊讶的是结束了比工作顺序更复杂的任何事情 – 这是在尝试这个时髦的壮举一两天后。

我估计我可能会在更短的时间内重build（工作）机器。考虑到RHEL5还有几年的支持，这也是一样的。

问题

问题如下：

RHEL6的rpm文件使用不同的幻数
RHEL5 python2.4不能识别用于CentOS 6中校验和下载的sha256
yum在RHEL6中使用不同的数据库格式，这样RHEL5 yum构build的chroot环境就不会被RHEL6中的yum所理解

解

警告：下面的问题1的解决scheme是危险的。 如果RPM升级中断，您可能最终导致系统损坏。 解决问题2可能导致安装破损的包裹！

通过从源RPM反向移植RPM 4.6，可以绕过问题1。见http://orcorc.blogspot.com/2009/03/oh-my-goodness.html 。

为soure RPM构build依赖关系：

 $ yum install redhat-rpm-config elfutils-devel elfutils-libelf-devel readline-devel zlib-devel nss-devel gettext-devel libselinux-devel ncurses-devel bzip2-devel python-devel lua-devel xz-devel xz

没有适当的lua在我的CentOS分区。从rpmsearch获取：

 $ rpm -i lua-5.1.2-1.el5.x86_64.rpm lua-devel-5.1.2-1.el5.x86_64.rpm

安装并构build源RPM。当然可能需要额外的软件包，比如gcc：

 $ rpm -i rpm-4.6.0-4.0.notting.1.el5.src.rpm $ rpmbuild -ba /usr/src/redhat/SPECS/rpm.spec

在实际安装更换RPM之前进行testing：

 $ rpm -U --test /usr/src/redhat/RPMS/i386/rpm-4.6.0-4.0.notting.1.i386.rpm /usr/src/redhat/RPMS/i386/rpm-libs-4.6.0-4.0.notting.1.i386.rpm /usr/src/redhat/RPMS/i386/rpm-python-4.6.0-4.0.notting.1.i386.rpm /usr/src/redhat/RPMS/i386/rpm-build-4.6.0-4.0.notting.1.i386.rpm

我们现在可以安装基线：

 $ rpm -i --root=/mnt centos-release-6-0.el6.centos.5.i686.rpm

问题2可以通过手动编辑/usr/lib/python2.4/site-packages/yum文件来解决（PYTHONPATH的魔法可以用来使这个稍微less一些）。差异看起来如此：

 --- yum-python/__init__.py 2011-10-05 11:03:00.000000000 +0200 +++ /usr/lib/python2.4/site-packages/yum/__init__.py 2011-10-05 11:14:24.000000000 +0200 @@ -1215,7 +1215,7 @@ if ylp.pkgtup != po.pkgtup: failed = True - + failed = False if failed: # if the file is wrong AND it is >= what we expected then it # can't be redeemed.

我们现在准备执行yum groupinstall：

 $ yum groupinstall --nogpgcheck --installroot=/mnt core

请注意，由于我们禁用了大部分包validation，所以在这一步可能会导致安装失败。密切关注输出：

 Failed: python.i686 0:2.6.5-3.el6_0.2 redhat-logos.noarch 0:60.0.14-10.el6 $ yum install --nogpgcheck --installroot=/mnt python redhat-logos

冲洗并重复。

由于核心不会做任何系统设置，您可能需要在下一步之前做任何事情。我需要提供/mnt/etc/resolv.conf。

现在我们有了一个可以解决问题3的环境：

 $ SHELL=/bin/bash chroot /mnt $ yum install zsh error: cannot open Packages index using db3 - No such file or directory (2) error: cannot open Packages database in /var/lib/rpm

幸运的是，这很容易解决：只需重build/ var / lib / rpm：

 $ mv /var/lib/rpm/ /var/lib/old.rpm $ rpm --initdb

在这一点上，我遇到了经典的$ releasever问题，所以我不得不编辑/etc/yum.repos.d/*来将$ releaseverreplace为6.例如：

 sed -re 's/\$releasever/6/g' -i /etc/yum.repos.d/CentOS-Base.repo

可能有更好的方法来做到这一点，但我还没有find。

 $ yum install zsh Loaded plugins: fastestmirror Determining fastest mirrors YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. $releasever is not a valid release or hasnt been released yet/ removing mirrorlist with no valid mirrors: /var/cache/yum/i386/$releasever/base/mirrorlist.txt Error: Cannot find a valid baseurl for repo: base

编辑完成后，yum按预期工作，而且我有一个从CentOS 5构build的CentOS 6。任何CentOS 6的chroot环境/ guest虚拟机guest安装指令应该能够让你成为一个全面的系统。

大，

在这种情况下，我的系统崩溃，需要做一些更多的系统方面的creazy。

许多事情是如此依赖于系统的实际状态，所以除了不同之外， 最重要的是要解决“RPM：坏魔法”

开始之前检查其他方式！如

Sometihing是错误的？ 那么你可以使用rpm2cpio或mc来提取cpio，然后cpio提取rpm文件并手动复制到文件夹不要忘记运行ldconfig之后

可能你必须获取新版本的cpio来提取cpio内容

所以我即将去el6版本来解决这个问题。

意思是，必须让RPM再次工作，然后我可以重新安装其他软件包。

由于系统被破坏，没有更多的el6库可供安装，必须编译所有依赖于源代码的东西。

1）尽可能多地从el5版本库中安装yum与devel软件包，其中头文件是nss3 + devel lzma + devel nspr4 + devel ncurses + devel readline db-4.5.20 + devel rpm-libs + devel

在其他情况下不得不下载源代码并进行编译

2）继续前进cpio，lzma获取SRPM和补丁的内容下载cpio 2.10+更好=从主页编译并安装 下载rpm 4.6.0+更好=从主页编译并安装 下载rpm-libs 4.6.0+更好=从主页编译并安装 下载db-4.5.20更好=从主页编译安装

rpm * el6有4.8。*但兼容性好4.6+

如果rpmbuild –rebuild将会在midle行中变得完整，那么意味着GOD祝福你，并且你已经安装了适当版本的头文件和库文件

或者对于其他的依赖下载src.rpm文件解压缩rpm，cpio，主压缩包将补丁应用到一个文件夹

http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/

总是应用修补程序，必须指定正确的文件名或在同一文件夹中创build符号链接

 ls *.patch.bz2|while read a;do bzcat $a > $a.patch;done ls *.patch.gz|while read a;do zcat $a > $a.patch;done ls cpio*.patch|while read p;do patch -p0 < "$p";done

毕竟build立像lzma和其他你必须做的库

 ldconfig

用于configurationRPM

 CFLAGS="-lncurses -lnss3 -I/usr/include/nss3 -I/usr/include/nspr4 -lnspr4" ./configure --prefix=/usr --with-lua --with-lzma --with-nss3 --with-nspr4 --with-external-db make

其他configuration如cpio

 CFLAGS="-lncurses -lnss3 -I/usr/include/nss3 -I/usr/include/nspr4 -lnspr4" # or specify bin folder ./configure --prefix=/ make # test, !!! make backup of rpm binaries and libs in case rollback /usr/lib/rpm /usr/bin /bin and rpm-db make install # then move man and other to /usr/share from / where are now

在回滚的情况下，你必须重新安装rpm manualy或用备份版本replace文件并运行ldconfig

命令

一切正确吗？

％make install

并继续“我们现在可以安装baseline：”，或者如果您只是更新从/etc/yum.repos.d中删除其他存储库只保留el6包

小心，如果你不确定是否有一些删除，你必须用rpm来安装manualy

 yum clean all yum update --skip-broken package-clean --problems package-clean --dups yum update

从安装DVD创build本地存储库只是安装isos到mnt并在mnt中调用

 yum install yum-utils cd /mnt createrepo .
