Ansible

To create an Ansible playbook that installs MySQL 5.7 on Ubuntu 22.04 Live Server, follow these steps:

Install Ansible on your control machine.

Create an inventory file (e.g., hosts.ini) that lists the target server(s). Replace the server_ip and ansible_user with the appropriate values for your target server:

csharp
Copy code
[mysql_servers]
server_ip ansible_user=your_user
Create a new file called install_mysql57.yml and add the following content:
yaml
Copy code
---
- name: Install MySQL 5.7 on Ubuntu 22.04
  hosts: mysql_servers
  become: yes
  tasks:
    - name: Update apt cache
      ansible.builtin.apt:
        update_cache: yes
        cache_valid_time: 3600

    - name: Install software-properties-common
      ansible.builtin.apt:
        name: software-properties-common
        state: present

    - name: Add MySQL APT repository
      ansible.builtin.apt_repository:
        repo: 'deb http://repo.mysql.com/apt/ubuntu/ focal mysql-5.7'
        state: present
        update_cache: yes

    - name: Install MySQL APT GPG key
      ansible.builtin.apt_key:
        url: 'https://repo.mysql.com/RPM-GPG-KEY-mysql'
        state: present

    - name: Install MySQL Server 5.7
      ansible.builtin.apt:
        name: mysql-server
        state: present
        force_apt_get: yes

    - name: Start and enable MySQL service
      ansible.builtin.systemd:
        name: mysql
        state: started
        enabled: yes
This playbook does the following:

Updates the apt cache.
Installs the software-properties-common package to manage repositories.
Adds the MySQL APT repository for Ubuntu 20.04 (Focal Fossa) to install MySQL 5.7 on Ubuntu 22.04.
Installs the MySQL APT GPG key.
Installs the MySQL Server 5.7.
Starts and enables the MySQL service.
Run the playbook using the following command:
bash
Copy code
ansible-playbook -i hosts.ini install_mysql57.yml --ask-become-pass
This command will prompt you for the sudo password of the target server.

Please note that MySQL 5.7 is not officially supported on Ubuntu 22.04. The playbook above uses the MySQL APT repository for Ubuntu 20.04 (Focal Fossa) to install MySQL 5.7 on Ubuntu 22.04. It's recommended to use MySQL 8.0, which is the version officially supported on Ubuntu 22.04, or consider using an alternative like MariaDB.
