二、查看CPU信息
（1）查看cpu型号
[root@Master ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c 40 Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
（2）查看系统中实际物理CPU的数量（物理）
[root@Master ~]# grep 'physical id' /proc/cpuinfo | sort | uniq | wc -l 2
（3）系统中实际物理CPU的数量（核数）
[root@Master ~]# cat /proc/cpuinfo |grep 'processor'|wc -l 40
（4）查看每个物理CPU中core的个数(即核数)
[root@Master ~]# cat /proc/cpuinfo |grep "cores"|uniq cpu cores : 10
（5）查看CPU的主频
