我需要清理我的系统并重新做所有事情。有没有简单的方法可以删除我安装的每个软件包（直到 CentOS 最小化）？我记不住所有的软件包，
yum list installed
拉出上千个包裹的列表。
谢谢！
编辑：我无法重新安装 CentOS。
答案1
您应该重新安装系统。删除软件包以达到最小化需要的时间比重新安装最小化设置要多得多。如果无法重新安装，为什么不保持原样呢？您是否想节省空间？
无论如何，以下是 CentOS 最小 RPM 软件包列表。针对现有列表运行 diff 并确定要删除的内容：

答案2
这似乎不是遍历包列表并删除该包的简单情况，因为有些包是对于基本操作至关重要的系统包（除非您特别想破坏系统，那么您不妨重新安装）。
如果您想查看系统上有哪些软件包，但似乎不依赖任何东西，您可以package-cleanup --quiet --leaves从yum-utils（或package-cleanup --quiet --leaves --exclude-bin排除二进制文件）运行。
要自动删除所有被遗弃的软件包，请尝试：
package-cleanup --quiet --leaves --exclude-bin | xargs yum remove -y
答案3
您可以尝试在虚拟机中进行最小安装，然后比较软件包列表，从虚拟机中删除列表中不存在的软件包。也许可以结合@jamza 的回答
答案4
我不得不重新安装 CentOS... 浪费钱买 CD 驱动器，而且 RAM 也坏了，但我已经让服务器启动并运行了。
