几个cpu

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

每个cpu是几核（假设cpu配置相同）

more /proc/cpuinfo |grep "physical id"|grep "0"|wc -l

cat /proc/cpuinfo | grep processor

1. 查看物理CPU的个数
#cat /proc/cpuinfo |grep "physical id"|sort |uniq|wc -l
?
2. 查看逻辑CPU的个数
#cat /proc/cpuinfo |grep "processor"|wc -l
?
3. 查看CPU是几核
#cat /proc/cpuinfo |grep "cores"|uniq
?
4. 查看CPU的主频
#cat /proc/cpuinfo |grep MHz|uniq
