我想用crash在RHEL 7.0.由于crash需要vmlinux文件，但我在文件夹中找不到它/boot，只能vmlinuxz：
......
vmlinuz-0-rescue-7c50639231494746b5dffc0a1ff84727
vmlinuz-3.10.0-123.el7.x86_64
vmlinuz-3.10.0-123.el7.x86_64.debug
......
我已经从文件安装了所有 kernel*.pkg RHEL 7.0 ISO：
[root@localhost boot]# yum install kernel*

那么如何获取RHEL 7.0 vmlinux文件呢？
答案1
您需要为 RHEL 启用“debuginfo”存储库并安装 kernel-debuginfo rpm 以获得所需的 vmlinux
# rpm -qf /usr/lib/debug/lib/modules/3.10.0-229.14.1.el7.x86_64/vmlinux
kernel-debuginfo-3.10.0-229.14.1.el7.x86_64
有关如何启用此存储库的信息可以在以下位置找到： https://access.redhat.com/solutions/9907
