Playbook to backup all mysql databases

Question

Can I have an ansible playbook that backups all the mysql databases?

Answer 1

Hey @Ruth, you could use a playbook, something like this:

- name: backup mysql
  vars:
    - exclude_db:
      - "Database"
      - "information_schema"
      - "performance_schema"
      - "mysql"
  tasks:
    - name: get db names
      shell: 'mysql -u root -p{{ vault_root_passwd }} -e "show databases;" '
      register: dblist
    - name: backup databases
      mysql_db:
        state: dump
        name: "{{ item }}"
        target: "/tmp/{{ item }}.sql"
        login_user: root
        login_password: "{{ vault_root_passwd }}"
      with_items: "{{ dblist.stdout_lines | difference(exclude_db) }}"
