Credentialed Accounts
ACTIVE ACCOUNT
* google369434_student@qwiklabs.net
To set the active account, run:
 $ gcloud config set account `ACCOUNT`

 

2) $ gcloud config list project

=

[core]
project = qwiklabs-gcp-d5a796316a20c809
Your active configuration is: [cloudshell-23226] 

 

3) $ gcloud config set project <PROJECT_ID>

= gcloud 지원이 설정되어 있지 않을 경우 설정

google369434_student@qwiklabs-gcp-d5a796316a20c809:~$ gcloud config set project qwiklabs-gcp-d5a796316a20c809
Updated property [core/project]. 

 

NGINX Web Server Install

 

4) $ sudo su -

= SSH를 통해 접속한 다음 sudo로 root Access 권한을 얻기

google369493_student@gcelab:~$ sudo su -
root@gcelab:~#

 

 

5) $ apt-get update

= root 권한으로 OS를 업데이트

root@gcelab:~# apt-get update

7) $ ps auwx | grep nginx

= NGINX가 실행 중인지 확인

8) 설치한 Web Server 확인

= 마우스로 새 인스턴스(가상머신) 만들기

 

9) $ gcloud compute instances create gcelab2 --zone us-central1-c

= gcloud shell을 사용하여 새 인스턴스(가상머신) 만들기

= 정보 Debian8(Jessie)이미지, 머신유형(n1-standard-1) 등 확인가능

 

google369493_student@qwiklabs-gcp-5fda8dbf4ab97038:~$ gcloud compute instances create geclab2 --zone us-central1-c
Created [https://www.googleapis.com/compute/v1/projects/qwiklabs-gcp-5fda8dbf4ab97038/zones/us-central1-c/instances/geclab2].

10) $ gcloud compute instances create --help

= 모든 기본값을 확인하기위한 명령어

 

11) $ gcloud config set compute/zone ...

$ gcloud config set compute/region ...

= 항상 같은지역/영역에서 작업하려면 매번 --zone 플래그를 추가하고 싶지 않다면,

gcloud가 사용하는 기본지역 및 영역을 설정

 

12) $ gcloud compute ssh gcelab2 --zone us-central1-c

= gcloud를 통해 인스턴스에 SSH로 접속
