再去看看硬件信息，参考之前自己的帖子：
【已解决】CentOS中查看CPU和内存等硬件配置信息 – 在路上

和：
[root@lin-16core3 ~]# dmidecode | grep "Maximum Capacity" Maximum Capacity: 32 GB
和：
[root@lin-16core3 ~]# dmidecode | grep "Number Of Devices" Number Of Devices: 2
和：
# fdisk -l | grep GB Disk /dev/vda: 21.5 GB, 21474836480 bytes, 41943040 sectors
【总结】
此处可以通过：
cat /proc/cpuinfo | grep processor
看出：CPU是16核的
dmidecode | grep "Maximum Capacity" dmidecode | grep "Number Of Devices"
看出：内存是32G的，内存插槽是2个
fdisk -l | grep GB
看出：硬盘是21.5G
