[AWS EC2] Settings you want to do on Amazon Linux 2


When you start EC2, the settings you want to do first


1. Set the server time to JST

--Default is UTC --Change the timezone to Asia / Tokyo and set it to JST --Restart crond after changing the timezone

$ timedatectl status
      Local time: Fri 2020-06-26 06:10:18 UTC
  Universal time: Fri 2020-06-26 06:10:18 UTC
        RTC time: Fri 2020-06-26 06:10:18
       Time zone: n/a (UTC, +0000)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a
$ sudo timedatectl set-timezone Asia/Tokyo
$ timedatectl status
      Local time: Fri 2020-06-26 15:50:10 JST
  Universal time: Fri 2020-06-26 06:50:10 UTC
        RTC time: Fri 2020-06-26 06:50:09
       Time zone: Asia/Tokyo (JST, +0900)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a
$ sudo systemctl restart crond
$ date
Fri Jun 26 16:03:47 JST 2020

2. Change prompt

--The default is less information, so change it --Before change: [ec2-user @ ip-XX-XX-XX-XX ~] $ --After change: [16:17:47 ec2-user @ ip-XX-XX-XX-XX ~] $ --Add ʻexport PS1 to .bashrc --Edit$ PS1 in / etc / bashrc` if you want to reflect it in the whole --Don't forget to reflect with the source command

$ vi .bashrc

# User specific aliases and functions
export PS1='\[\033[37m\][\t \[\033[36m\]\u\[\033[37m\]@\h \[\033[32m\]\W\[\033[37m\]]$ '

$ source .bashrc

3. Change locale

――You don't have to do it, but if you want to have a Japanese environment, do it.

$ localectl status
   System Locale: LANG=en_US.UTF-8
       VC Keymap: n/a
      X11 Layout: n/a
$ sudo localectl set-locale LANG=ja_JP.UTF-8
$ sudo localectl set-keymap jp106
$ localectl status
   System Locale: LANG=ja_JP.UTF-8
       VC Keymap: jp106
      X11 Layout: jp
       X11 Model: jp106
     X11 Options: terminate:ctrl_alt_bksp

4. Install frequently used items

There is nothing else in it, so install the one you want to use. git

$ sudo yum install -y git
$ git -version
git version 2.23.3
