[PYTHON] Change the Amazon Linux locale to Japan using Ansible's lineinfile

■ What is Ansible?

• ** Features of Ansible ** --It is a tool that automates server construction without agents. --It connects to the machine running sshd with SSH and builds the environment. --Write the configuration file in YAML. No programming knowledge (Ruby, Python, etc.) is required. --It's easier than chef to build a few to dozens of servers.

• ** Preparing the environment ** Please refer to the previous article. Ansible First Step

■ Change the locale to Japan

• playbook.yml
  The lineinfile module replaces the character string. I have a symbolic link in the file module.

  - hosts: all
    remote_user: ec2-user
    become: true
    tasks:
      - name: set LANG
        lineinfile: >
          dest=/etc/sysconfig/i18n
          regexp='LANG=.*'
          line='LANG=ja_JP.utf8'
      - name: set ZONE
        lineinfile: >
          dest=/etc/sysconfig/clock
          regexp='ZONE=.*'
          line='ZONE="Asia/Tokyo"'
      - name: set UTC
        lineinfile: >
          dest=/etc/sysconfig/clock
          regexp='UTC=.*'
          line='UTC=false'
      - name: link localtime
        file: >
          src=/usr/share/zoneinfo/Asia/Tokyo
          dest=/etc/localtime
          state=link
          force=yes
  

• ansible-playbook I will try it.

  $ ansible-playbook playbook.yml
  target01               : ok=5    changed=4    unreachable=0    failed=0
