Linux查看物理CPU个数、核数，逻辑CPU个数，linux个数
学习swoole的时候，建议开启的worker进程数为cpu核数的1-4倍。于是就学习怎么查看CPU核数
# 查看物理CPU个数 cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l # 查看每个物理CPU核数 cat /proc/cpuinfo| grep "cpu cores"| uniq # 查看逻辑CPU个数 cat /proc/cpuinfo| grep "processor"| wc -l<br /><br /># 查看CPU信息（型号）<br />cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
