硬件系统重点关注的指标：
# 总核数 = 物理CPU个数 X 每颗物理CPU的核数
# 总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数
# 查看物理CPU个数
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
或grep 'physical id' /proc/cpuinfo | sort -u | wc -l
# 查看每个物理CPU中core的个数(即核数)
cat /proc/cpuinfo| grep "cpu cores"| uniq
或者grep 'core id' /proc/cpuinfo | sort -u | wc -l
# 查看逻辑CPU的个数
cat /proc/cpuinfo| grep "processor"| wc -l
或者grep 'processor' /proc/cpuinfo | sort -u | wc -l
# 查看CPU信息（型号）
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
或者dmidecode -s processor-version

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
48 Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz
# cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
2
# cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores: 12
# cat /proc/cpuinfo| grep "processor"| wc -l
48
理论上不使用超线程技术的前提下有如下结论:
物理CPU个数*核数=逻辑CPU个数
配置服务器的应用时，以逻辑CPU个数为准。5.内存信息查看：

# cat /sys/block/sda/queue/rotational
1
因为SSD是非转动盘，如果返回结果为0说明是SSD硬盘，如果返回结果为1，说明是转动盘HDD类的硬盘。
# lsblk -d -o name,rota

yum -y install hdparm
yum -y install install smartmontools
--查看磁盘的详细信息：
sudo hdparm -I /dev/sdb
sudo smartctl -a /dev/sda
--查看是否是SSD磁盘：
# sudo hdparm -I /dev/sdb

smart工具集的信息比hdparm的要更细致，你也可以使用图形界面下的smartctl，
首先安装图形界面安装包yum -y install gsmartcontrol12. 查看键盘和鼠标
cat /proc/bus/input/devices13.查看磁盘信息：
