我正在尝试创建自己的RPM包,这里是SPEC文件,它在安装时正常工作(rpm -ivh app-2.1-6.el6.x86_64.rpm)或升级(rpm - Uvh app-2.1-7.el6.x86_64.rpm)或删除(rpm -e app-2.1-7.el6.x86_64.rpm)
For RPM package app-2.1-7.el6.x86_64.rpm, the version is 2.1 and release number is 7.
我的问题是,无论我如何修改版本号,安装/升级/删除工作正常,但如果我将版本号修改为2.2或3.2,则以前的版本文件夹(/opt/app-2.1)将不能删除,任何人都可以帮助我,当我更新(-Uvh)RPM包时,我应该如何删除以前的版本文件夹(/opt/app-2.1)?
答案 0 :(得分:1)
问题是你的包裹没有“拥有” 目录/opt/2.1目录。
就像tar一样,rpm会创建所有“缺失”的目录 为了在路径上安装内容。
但是在擦除时,rpm只会删除那些目录 在%files manifest中明确提到。
简短回答: 如果你想要rpm --erase删除目录路径, 在%files中提及。
较短的anser: 加 %dir / opt / app - %{version} 到%文件。如果目录为空(即所有其他文件 在/ opt / app - %{version}是“拥有”并且可以删除), “own / opt / app =%{version}也将被删除。
