从已安装的rpm重新包装rpm [英] repackage an rpm from an installed rpm

问题描述

在Linux上，我们可以重新打包已安装的rpm.我记得可以从已安装的二进制文件生成rpm.

On linux can we repackage a installed rpm if so how.I remember that the a rpm can be generated from the installed binaries

  rpm -??? > my.rpm

同样，更新的rpm应该在另一台机器上运行

Also the later i.e, the newer rpm should work on a different machine

推荐答案

这是可能的，但不能使用 rpm 命令.我写了一个perl脚本来做到这一点.它根据 rpm -q 的输出来制作规格文件，并执行构建"，仅从系统中复制已安装的文件.

This is possible, but not with the rpm command. I wrote a perl script that does this; it crafts a spec file based on the outputs of rpm -q and does a "build" which just copies the installed files from the system.

用法示例，重新包装 mailx rpm:

Usage example, re-packaging the mailx rpm:

查询:

$ rpm -ql mailx
/bin/mail
/etc/mail.rc
/usr/bin/Mail
/usr/lib/mail.help
/usr/lib/mail.tildehelp
/usr/share/man/man1/Mail.1.gz
/usr/share/man/man1/mail.1.gz

重新包装:

$ ./rpm-repack -p mailx
Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.9773
+ umask 022
+ cd /usr/src/redhat/BUILD
+ /usr/lib/rpm/brp-compress
+ /usr/lib/rpm/brp-strip
+ /usr/lib/rpm/brp-strip-static-archive
+ /usr/lib/rpm/brp-strip-comment-note

Wrote: ~/rpmbuild/RPMS/i386/mailx-8.1.1-44.2.2.i386.rpm

查询新建软件包:

$ rpm -qpl ~/rpmbuild/RPMS/i386/mailx-8.1.1-44.2.2.i386.rpm
/bin/mail
/etc/mail.rc
/usr/bin/Mail
/usr/lib/mail.help
/usr/lib/mail.tildehelp
/usr/share/man/man1/Mail.1.gz
/usr/share/man/man1/mail.1.gz

代码一点也不优雅，但是可以正常工作.它确实复制了许多rpm信息(所有 rpm -qi 和大多数脚本中的信息)，但它并不全面.另外，它不能复制GPG签名，也不能与原始RPM文件具有相同的校验和.

The code isn't at all elegant, but functional. It does copy a lot of the rpm info (everything from rpm -qi and most of the scripts), but it isn't by any means comprehensive. Also, it can't copy the GPG signature, nor will it have the same checksums as the original RPM file.

注意::这不是构建和分发RPM软件包的正确"方法，主要用于故障排除和教育目的.

NOTE: This is not a "proper" way to build and distribute RPM packages, and was mainly written for troubleshooting and educational purposes.
