서버 사양 확인 (with 우분투)

자주 확인하는 서버 사양 명령어를 정리해 보았다.

1. os 확인

cat /etc/issue

---

2. cpu 확인

model name 확인

$ cat /proc/cpuinfo

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 158
model name      : Intel(R) Core(TM) i5-7500T CPU @ 2.70GHz

3. 메모리 확인

$ cat /proc/meminfo | grep Mem

MemTotal:       12183524 kB

4. hdd, ssd 확인

4-1. hdd, ssd 구분

0 SSD, 1 HDD

$ lsblk -d -o name,rota

NAME    ROTA
nvme0n1    0    
sda        1

4-2. hdd, ssd 각 용량 확인

위에 name과 맞는 것을 찾아 용량을 확인한다.

~$ sudo fdisk -l
