1. 查看主板信息：dmidecode |grep -A16 "System Information$"2. 查看cpu信息：CPU总核数 = 物理CPU个数 * 每颗物理CPU的核数 
总逻辑CPU数 = 物理CPU个数 * 每颗物理CPU的核数 * 超线程数查看CPU信息（型号） [root@esggy-clu-n003 ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c      24  Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz # 查看物理CPU个数 [root@esggy-clu-n003 ~]# cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l 2 # 查看每个物理CPU中core的个数(即核数) [root@esggy-clu-n003 ~]# cat /proc/cpuinfo| grep "cpu cores"| uniq cpu cores       : 6 # 查看逻辑CPU的个数 [root@esggy-clu-n003 ~]# cat /proc/cpuinfo| grep "processor"| wc -l 243. 查看内存信息：（需要安装rpm -qa|grep dmidecode）查看服务器型号、序列号： [root@esggy-clu-n003 ~]# dmidecode|grep "System Information" -A9|egrep "Manufacturer|Product|Serial" Manufacturer: Dell Inc. Product Name: PowerEdge R720 Serial Number: 9NLH422 Linux 查看内存的插槽数,已经使用多少插槽.每条内存多大： [root@esggy-clu-n003 ~]# dmidecode|grep -A5 "Memory Device"|grep Size|grep -v Range Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: 16384 MB Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Size: No Module Installed Linux 查看内存的频率： [root@esggy-clu-n003 ~]# dmidecode|grep -A16 "Memory Device"|grep 'Speed' Speed: 1600 MHz Speed: 1600 MHz Speed: 1600 MHz Speed: 1600 MHz Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: 1600 MHz Speed: 1600 MHz Speed: 1600 MHz Speed: 1600 MHz Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown Speed: Unknown 在linux查看内存型号的命令： dmidecode -t memory 查看主板型号： dmidecode |grep -A16 "System Information$" 内存槽及内存条： dmidecode |grep -A16 "Memory Device$" 硬盘： fdisk -l smartctl -a /dev/sda 网卡： mii-tool4. 查看硬盘信息：[root@esggy-clu-n003 ~]# fdisk -l | grep "Disk /dev/sd" Disk /dev/sdb: 1999.8 GB, 1999844147200 bytes Disk /dev/sdc: 1999.8 GB, 1999844147200 bytes Disk /dev/sda: 1999.8 GB, 1999844147200 bytes Disk /dev/sde: 1999.8 GB, 1999844147200 bytes Disk /dev/sdf: 1999.8 GB, 1999844147200 bytes Disk /dev/sdg: 1999.8 GB, 1999844147200 bytes Disk /dev/sdd: 1999.8 GB, 1999844147200 bytes [root@esggy-clu-n003 ~]# fdisk -l | grep 1999.8 | wc -l 7
