AWS EC2 인스턴스의 Amazon Linux 시간 설정

아마존에서 EC2 인스턴스를 설치하고 나면 시간이 맞지 않는다. 그것은 기본적으로UTC 시간을 사용하기 때문인다. tzselect 유틸리티를 사용하여 해당 지역을 선택하여 시간을 설정할 수있다.

root@empower-esp:~# tzselect 

Please identify a location so that time zone rules can be set correctly.

Please select a continent or ocean.

 1) Africa

 2) Americas

 3) Antarctica

 4) Arctic Ocean

 5) Asia

 6) Atlantic Ocean

 7) Australia

 8) Europe

 9) Indian Ocean

10) Pacific Ocean

11) none - I want to specify the time zone using the Posix TZ format.

#? 7

Please select one of the following time zone regions.

1) Lord Howe Island 8) Queensland - most locations

2) Macquarie Island 9) Queensland - Holiday Islands

3) Tasmania - most locations 10) South Australia

4) Tasmania - King Island 11) Northern Territory

6) New South Wales - most locations 13) Western Australia - Eucla area

7) New South Wales - Yancowinna

#? 5

The following information has been given:

Australia

Victoria

Therefore TZ='Australia/Melbourne' will be used.

Local time is now: Thu Jul 30 18:55:59 AEST 2015.

Universal Time is now: Thu Jul 30 08:55:59 UTC 2015.

Is the above information OK?

1) Yes

2) No

#? 1

You can make this change permanent for yourself by appending the line

TZ='Australia/Melbourne'; 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:

Australia/Melbourne

root@empower-esp:~# TZ='Australia/Victoria'; export TZ

그리고 이것을 /etc/profile 파일에 기록해 놓으면 시스템이 부팅되더라도 유지가 되겠다.

# /etc/profile

# System wide environment and startup programs, for login setup

# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you

# are doing. It's much better to create a custom.sh shell script in

# /etc/profile.d/ to make custom changes to your environment, as this

# will prevent the need for merging in future updates.

TZ='Australia/Victoria'; export TZ
