-----------------------------------------------------
开始系统里面并没有 lscpu 这个命令，要yum install util-linux-ng软件包，或者手动编译安装较新版本。
tar jxvf util-linux-ng-2.18.tar.bz2? #文章附件有这个软件包下载
cd util-linux-ng-2.18
./configure --enable-arch --enable-partx --enable-write
make
make install
?
OK, 可以用lscpu了，查看是属于哪个软件包：
rpm -qf `which lscpu`
?
