[Ubuntu] 리눅스 우분투 timezone 설정

리눅스 우분투 timezone 설정

AWS EC2 서버를 사용하면 기본 지역이 한국으로 되지 않기 때문에 서버 시간이 한국과 다르다.

 

우분투 timezone(서버 시간)은 'date' 명령어를 입력하면 확인할 수 있다.

ubuntu@SERVER:~/$ date
Mon May 16 00:12:41 UTC 2022

 

 

crontab과 같은 시간 예약 작업을 할 때 시간이 다르면 번거로우니 변경하도록 하자.

 

1. 'timedatectl' 명령어를 통해 변경할 수 있다.

ubuntu@SERVER:~/$ sudo timedatectl set-timezone 'Asia/Seoul'
ubuntu@SERVER:~/$ date
Sat May 16 19:52:25 KST 2020

 

2. 'tzslect' 명령어를 통해 변경하는 방법도 있다.

ubuntu@SERVER:~/$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", or "TZ".
 1) Africa
 2) Americas
 3) Antarctica
 4) Asia
 5) Atlantic Ocean
 6) Australia
 7) Europe
 8) Indian Ocean
 9) Pacific Ocean
10) coord - I want to use geographical coordinates.
11) TZ - I want to specify the time zone using the Posix TZ format.

The following information has been given:

        Korea (South)

Therefore TZ='Asia/Seoul' will be used.
Selected time is now:   Mon May 16 09:14:31 KST 2022.
Universal Time is now:  Mon May 16 00:14:31 UTC 2022.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by appending the line
        TZ='Asia/Seoul'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Seoul

이후 위의 안내대로  .profile 파일에 설정 값들을 추가해주면 timezone이 변경된다.

ubuntu@SERVER:~/$ echo "TZ='Asia/Seoul'; export TZ" >> .profile
ubuntu@SERVER:~/$ source ~/.profile
