一、查看CPU信息
1、 查看物理CPU的个数
[root@centos7 data]# cat /proc/cpuinfo |grep "physical id"|sort|uniq|wc -l
22、 查看CPU是几核
[root@centos7 data]# cat /proc/cpuinfo |grep "cores"|uniq
cpu cores : 23、 查看逻辑CPU的个数
[root@centos7 data]# cat /proc/cpuinfo |grep "processor"|wc -l
44、 查看CPU的主频
[root@centos7 data]# cat /proc/cpuinfo |grep "GHz"|uniq
model name : Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz5、 同时查看逻辑CPU个数和CPU核数
[root@centos7 data]# cat /proc/cpuinfo |grep name |cut -f2 -d:|uniq -c
4 Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz6、 使用lscpu命令，可以一次查看所有信息
[root@centos7 data]# lscpu

三、 查看磁盘信息
1、 查看磁盘挂载信息（常用）
[root@centos7 data]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 200G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 199G 0 part
├─centos-root 253:0 0 145G 0 lvm /
├─centos-swap 253:1 0 4G 0 lvm [SWAP]
└─centos-data 253:2 0 50G 0 lvm /data
sr0 11:0 1 1024M 0 rom2、 查看磁盘具体信息
[root@centos7 data]# fdisk -l
Disk /dev/sda: 214.7 GB, 214748364800 bytes, 419430400 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000a26b6
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 2099199 1048576 83 Linux
/dev/sda2 2099200 419430399 208665600 8e Linux LVM
Disk /dev/mapper/centos-root: 155.7 GB, 155684175872 bytes, 304070656 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/centos-swap: 4294 MB, 4294967296 bytes, 8388608 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/mapper/centos-data: 53.7 GB, 53687091200 bytes, 104857600 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes四、 查看网卡信息
[root@centos7 data]# mii-tool ens33 #ens33表示网卡名称
ens33: negotiated 1000baseT-FD flow-control, link ok #虚拟机环境是千兆 ，link ok 表示正在连接当中内容总结
