1、查看CPU型号

   cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

示例：

[root@n13 log]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

32  Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz

2、查看物理CPU个数

cat /proc/cpuinfo| grep "physical id" | sort | uniq | wc -l

示例：

[root@n13 log]# cat /proc/cpuinfo| grep "physical id" | sort | uniq | wc -l

2

3、查看逻辑CPU的个数

cat /proc/cpuinfo| grep "processor" | wc -l

示例：

[root@n13 log]# cat /proc/cpuinfo| grep "processor" | wc -l

32

4、查看每个物理CPU中core的个数(即核数)

cat /proc/cpuinfo | grep "cpu cores" | uniq

示例：

[root@n13 log]# cat /proc/cpuinfo | grep "cpu cores" | uniq

cpu cores       : 8
