linux下查看cpu、内存和硬盘大小

查cpu

#dmesg |grep -ixeon

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

显示8颗cpu，型号是E5520

上网搜出Intel XeonE5520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 5954
Swap: 5535 0 5535

内存是6.076G

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/mapper/VolGroup00-LogVol00

/dev/cciss/c0d0p1 99 31 64 33% /boot
none 3039 0 3039 0% /dev/shm

硬盘132G+3G=135G

top 回车，按1，可以看到cpu和内存
