  （4）查看网卡信息

[root@Master ~]# dmesg | grep -i Ethernet

igb: Intel(R) Gigabit Ethernet Network Driver - version 5。3。0-k

igb 0000:04:00。0: Intel(R) Gigabit Ethernet Network Connection

igb 0000:04:00。1: Intel(R) Gigabit Ethernet Network Connection

igb 0000:04:00。2: Intel(R) Gigabit Ethernet Network Connection

igb 0000:04:00。3: Intel(R) Gigabit Ethernet Network Connection

igb 0000:02:00。0: Intel(R) Gigabit Ethernet Network Connection

igb 0000:02:00。1: Intel(R) Gigabit Ethernet Network Connection 

（5） 查看pci信息，即主板所有硬件槽信息

[root@Master ~]# lspci | head -10

00:00。0 Host bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 DMI2 (rev 02)

00:01。0 PCI bridge: Intel Corporation Xeon E7 v3/Xeon E5 v3/Core i7 PCI Express Root Port 1 (rev 02)

二、查看CPU信息

（1）查看cpu型号

[root@Master ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

     40  Intel(R) Xeon(R) CPU E5-2650 v3 @ 2。30GHz

（2）查看系统中实际物理CPU的数量（物理）

[root@Master ~]# grep 'physical id' /proc/cpuinfo | sort | uniq | wc -l

2

（3）系统中实际物理CPU的数量（核数）

[root@Master ~]# cat /proc/cpuinfo |grep 'processor'|wc -l

40

 （4）查看每个物理CPU中core的个数(即核数)
