1、逻辑cpu个数（线程数）
[root@centos79 test]# cat /proc/cpuinfo | grep "processor" processor : 0 processor : 1 processor : 2 processor : 3 [root@centos79 test]# cat /proc/cpuinfo | grep "processor" | wc -l 4
2、物理cpu个数
[root@centos79 test]# cat /proc/cpuinfo | grep "physical id" physical id : 0 physical id : 0 physical id : 1 physical id : 1 [root@centos79 test]# cat /proc/cpuinfo | grep "physical id" | sort | uniq -c 2 physical id : 0 2 physical id : 1 [root@centos79 test]# cat /proc/cpuinfo | grep "physical id" | sort | uniq -c | wc -l 2
3、查看每个cpu核心数
[root@centos79 test]# cat /proc/cpuinfo | grep "cpu cores" cpu cores : 2 cpu cores : 2 cpu cores : 2 cpu cores : 2 [root@centos79 test]# cat /proc/cpuinfo | grep "cpu cores" | uniq | awk -F: '{print $2}' 2
4、查看cpu型号
[root@centos79 test]# dmidecode -s processor-version | uniq AMD Ryzen 5 3600X 6-Core Processor
5、汇总
