编译内核源码

升级一些依赖包

sudoyum installrpm-build redhat-rpm-config asciidoc hmaccalc perl-ExtUtils-Embed pesign xmlto

sudoyum installaudit-libs-devel binutils-devel elfutils-devel elfutils-libelf-develsudo 

yum installncurses-devel newt-devel numactl-devel pciutils-devel python-devel zlib-devel bison

创建源码的编译书目录，目的源码存放地址

mkdir -p ~/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}

echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros

安装到编译目录

rpm -i kernel-3.10.0-229.20.1.el7.src.rpm 2>&1 | grep -v exist

cd ~/rpmbuild/SPECS

rpmbuild -bp --target=$(uname -m) kernel.spec

最终的内核源码位置如下
