# Backup MySql databases from remote server



** Description

I have wordpress websites running on VPS server and I need a solution to backup these databases regulerly.

We will create an [[https://www.ansible.com][ansible]] playbook (step by stepp process) to automate the solution.



** Prerequisites

 - [[https://docs.oracle.com/en/cloud/cloud-at-customer/occ-get-started/generate-ssh-key-pair.html][ssh key]] (make sure public key has been uploaded to remote server)

 - [[https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html][ansible]]

 - A running instance of MySQL



** Step 1: Create inventory file

Create new file as 'server.inventory.ini'

#+BEGIN_SRC

touch server.inventory.ini

#+END_SRC



Add the following details

#+BEGIN_SRC

[Server-VPS]

# server address here



[Server-VPS:vars]

ansible_connection=ssh

ansible_user= # remote server username

#+END_SRC



** Step 2: Create vault file

*** Step 2.1: Create file with secrets

Create new file as 'database_vault.yaml'

#+BEGIN_SRC

touch database_vault.yaml

#+END_SRC



Add the following details

#+BEGIN_SRC

 db_name: # database name here

 db_user_name: # database username here

 db_user_password: # database user password here

#+END_SRC



*** Step 2.2: Encrypt secret file

Please run the following command to [[https://www.digitalocean.com/community/tutorials/how-to-use-vault-to-protect-sensitive-ansible-data-on-ubuntu-16-04#:~:text=To%20create%20a%20new%20file,encrypted%20YAML%20file%20called%20vault.][encrypt]] newly created secrets file.

#+BEGIN_SRC

 ansible-vault encrypt database_vault.yaml

#+END_SRC



#+BEGIN_SRC

 # output

 New Vault password: 

 Confirm New Vault password:

 Encryption successful

#+END_SRC



*** Step 3: Create playbook

Create new file as 'database_backup_playbook.yaml'

#+BEGIN_SRC

touch database_backup_playbook.yaml

#+END_SRC



Add the following details

#+BEGIN_SRC yaml :tangle database_backup_playbook.yaml

  ---

  - hosts: Server-VPS

    gather_facts: true

    vars_files:

      - database_vault.yaml

    tasks:

      - name: Create variables

        set_fact:

          db_file_name: "{{ db_name }}_{{ ansible_date_time.date | replace('-','') }}.sql"

      

      - name: Confirm hostname

        debug:

          msg: Logged into the server.



      - name: Download Database to server

        shell: |

          mysqldump -u {{ db_user_name}} -p"{{ db_user_password }}" {{ db_name }} --quick --lock-tables=false > "{{ db_file_name }}" --no-tablespaces

        no_log: true



      - name: Wait until the database backup completed on server

        wait_for:

          path: "{{ db_file_name }}"

          state: present

          msg: "Timeout to find file {{ db_file_name }}"



      - name: Downloading backup to local computer

        ansible.builtin.fetch:

          src: "{{ db_file_name }}"

          dest: "{{ db_file_name }}"

          flat: yes



      - name: Download completed

        debug:

          msg: Database have been downloaded successfully.

#+END_SRC



*** Step 4: Time to playbook to run manually in command-line:



*** Step 4.1 - Run ssh-agent

If you have the passpharace added to ssh key then it will be easier to run it manually.

#+begin_src

  eval $(ssh-agent)

  ssh-add ./path/to/ssh/key

#+end_src



*** Step 4.2 - Execute playbook

Please execute following command to run the playbopk and start the process.

#+BEGIN_SRC bash

  ansible-playbook -i server.inventory.ini database_backup_playbook.yaml --ask-vault-password

#+END_SRC



*** Step 4.3: Enter vault password.

Please enter the vault password so that ansible can decyrpt the `database_vault.yaml` variables to use in the playbook.
