安裝需要的軟體：
yum install setools-console
yum install httpd
yum install policycoreutils-python setools-console
yum -y install vsftpd ftp
yum install m4
yum -y install gcc
安裝核心編譯的軟體：
yum install rpm-build xmlto hmaccalc asciidoc newt-devel pesign binutils-devel audit-libs-devel numactl-devel
 
 pciutils-devel ncurses-devel perl-ExtUtils-Embed elfutils-devel python-devel ruby-devel libsepol-static swig xz-devel ruby checkpolicy policycoreutils-devel
下載核心原始碼：
wget http://vault.centos.org/centos/7/os/Source/SPackages/kernel-3.10.0-514.el7.src.rpm
安裝核心原始碼：
rpm -i kernel-3.10.0-514.el7.src.rpm
編譯原始碼: 
cd /root/rpmbuild/SPECS/
 

rpmbuild -bb kernel.spec
注：安裝編譯原始碼報錯處理：
    yum install mock
    useradd -s /sbin/nologin mockbuild
    yum install bison 
編譯過程中核心的原始碼會被解壓縮，並打好補丁，釋放在
/root/rpmbuild/BUILD目錄。
編譯後的kernel會在/root/rpmbuild/RPMS中
