linux下查看cpu、內存和硬盤大小

• 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

顯示8顆cpu，型號是E5520

上網搜出Intel XeonE5520是4核，因此查詢的機器是2顆cpu，每顆cpu四核

• 查內存

#free-m  以MB爲單位查詢內存

            total      used      free    shared   buffers    cached
Mem:         6076       572      5504         0        57       392
-/+buffers/cache:       121      5954
Swap:        5535         0      5535

內存是6.076G

• 查硬盤大小

#df -m 以MB爲單位查詢

Filesystem            1M-塊       已用    可用 已用% 掛載點
/dev/mapper/VolGroup00-LogVol00
                       132166     2779   122674   3% /
/dev/cciss/c0d0p1          99       31       64  33% /boot
none                     3039        0     3039   0% /dev/shm

硬盤132G+3G=135G
