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

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.查看内存总数

#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //内存32G

3. 查看硬盘大小

# fdisk -l | grep Disk

Disk /dev/cciss/c0d0: 146.7 GB, 146778685440 bytes

总结：硬盘大小146.7G，即厂商标称的160G
