Linux下查看CPU型号,内存大小,硬盘空间命令

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
