1.查看CPU架构信息
lscpu
[root@iZ94oaf8*** ~]# lscpu

2. 查看内存信息
free -m
[root@iZ94oaf**** ~]# free -m
total used free shared buffers cached

3. 查看硬盘信息 blk是block的缩写，列出块设备
lsblk
[root@iZ94oaf**** ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 252:0 0 20G 0 disk
└─vda1 252:1 0 20G 0 part /
vdb 252:16 0 200G 0 disk /home
4. 查看硬盘的使用情况
df -h
[root@iZ94oaf**** ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 15G 3.9G 80% /
tmpfs 7.8G 136K 7.8G 1% /dev/shm
/dev/vdb 197G 32G 156G 17% /home
5、查看CPU使用情况
top
6、查看文件占用空间大小
du -h --max-depth=1
