Linux 查看CPU，内存，硬盘

1 查看CPU


1.1 查看CPU个数
# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2
**uniq命令：删除重复行；wc –l命令：统计行数**


1.2 查看CPU核数
# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores       : 4


1.3 查看CPU型号
# cat /proc/cpuinfo | grep 'model name' |uniq
model name      : Intel(R) Xeon(R) CPU           E5630  @ 2.53GHz


总结：该服务器有2个4核CPU，型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz


2 查看内存


2.1 查看内存总数
#cat /proc/meminfo | grep MemTotal
MemTotal:     32941268 kB  //内存32G


2.2 查看内存条数
