RHEL7内核源代码在哪里安装？

Question

我安装了Linux内核源代码RPM：

[root@localhost ~]# rpm -ivh kernel-3.10.0-229.el7.src.rpm
warning: kernel-3.10.0-229.el7.src.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY

安装过程似乎成功，但使用rpm -ql kernel-3.10.0-229.el7.src命令无法找到安装源代码的位置：

[root@localhost ~]# rpm -ql kernel-3.10.0-229.el7.src
package kernel-3.10.0-229.el7.src is not installed

RHEL7内核源代码在哪里安装？

更新：rpm -qa | grep kernel命令输出：

[root@localhost ~]# rpm -qa | grep kernel
kernel-headers-3.10.0-229.el7.x86_64
kernel-devel-3.10.0-229.el7.x86_64
kernel-3.10.0-229.el7.x86_64
kernel-tools-libs-3.10.0-229.el7.x86_64
abrt-addon-kerneloops-2.1.11-19.el7.x86_64
kernel-tools-3.10.0-229.el7.x86_64

Answer 1

源包不会添加到rpm数据库中，因此它们不会显示在查询中。

可能的位置是~/ rpmbuild /{source/ SPECS}，其中包含包源和分发修补程序的源，而包含用于构建包的.spec文件的SPECS子目录(有关详细信息，请参见rpmbuild (8)手册页)。

如果您在那里找不到源代码，请使用-vv选项重新安装，以检查该位置是否被覆盖：

$ rpm -ivvh kernel-3.10.0-229.7.2.el7.src.rpm

Answer 2

它应该在/usr/src/内核下面。

如果你找不到它，你可以试试

rpm -qa| grep -w内核-devel

rpm -ql内核-devel-x.x

这将给出由内核rpm安装的文件的位置。

通过这种方式，内核源代码应该安装在内核-devel包中，而不是内核-x.x。
