Mik*_*e B 3 rpm centos package-management
我想降级几个 RPM。有没有开关组合?例如,在升级时,我通常会运行,rpm -Uvh foo.rpm但我的理解是-U切换意味着它仅在包较旧时才替换它......因此它不适用于降级。
请尝试以下操作:
$ rpm -Uvh --oldpackage pkg1.rpm pkg2.rpm

摘自 rpm 手册页
rpm {-U|--upgrade} [install-options] PACKAGE_FILE ...
This upgrades or installs the package currently installed to a newer
version. This is the same as install, except all other version(s) of the
package are removed after the new package is installed.
--oldpackage
Allow an upgrade to replace a newer package with an older one.

如果您之前安装了 pkgX-1.0,然后将其升级到 pkgX-1.1,您应该能够使用yum history查看此升级并yum history undo恢复此升级。
摘自 yum man page on history
撤消/重做/回滚命令采用单个事务 id 或关键字 last 和最后一个事务的偏移量(例如,如果您完成了 250 个事务,“last”指的是事务 250,而“last-4”指的是到交易 246)。在指定事务之前,重做命令还可以采用一些可选参数。“强制重新安装”告诉它重新安装在该事务中安装的任何软件包(通过安装、升级或降级)。“force-remove”告诉它强制删除任何更新或降级的包。
撤消/重做命令作用于指定的事务,撤消或重复该事务的工作。而回滚命令将撤消直到指定事务点的所有事务。例如,如果您有 3 个交易,其中包 A;B 和 C 分别安装。然后“undo 1”将尝试删除包A,“redo 1”将尝试安装包A(如果尚未安装),而“rollback 1”将尝试删除包B和C。注意在“ rollback 1" 您将有第四个事务,尽管结束 rpmdb 版本(请参阅:yum 版本)在事务 1 和 4 中应该相同。
