查cpu

# dmesg |grep -i xeon

CPU0: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU1: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU2: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU3: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU4: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU5: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU6: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05
CPU7: Intel(R) Xeon(R) CPU E5520 @ 2.27GHz stepping 05

备注：
显示8颗cpu，型号是E5520
上网搜出Intel Xeon E5520是4核，所以查询的机器是2颗cpu，每颗cpu四核

查内存

# free -m  以MB为单位查询内存

total used free shared buffers cached Mem: 6076 572 5504 0 57 392 -/+ buffers/cache: 121 5953 Swap: 5535 0 5535

备注：
内存是6.076G，可用5953Ｍ

查硬盘大小

#　df -m  以MB为单位查询

Filesystem 1M-块已用可用已用% 挂载点 /dev/sda3 182781 30412 142935 18% / /dev/sda1 99 12 82 13% /boot tmpfs 3992 0 3992 0% /dev/shm

备注：
硬盘1８２G+3G=１８５G
