Using MySQL databases

In this recipe, you will learn how to create and remove databases in MySQL. You will also learn how to interrelate these definitions with other Salt definitions, and make all the database components work together.

How to do it...

We will use the same minion as the previous recipe.

  1. Create and edit /opt/salt-cookbook/staging/mysql/database.sls to have the following entries:

    include:
  - mysql

MySQL-python:
  pkg.installed

stg_databases:
  mysql_database.present:
    - name: stagingdb
    - require:
      - pkg: MySQL-python
      - service: mysql_service

databases_to_remove:
  mysql_database.absent:
    - name: test
    - require:
      - pkg: MySQL-python
      - service: mysql_service

  2. Apply the state to the minion, using the following command:

    [root@salt-master ~]# salt 'salt-minion-mysql' state.sls mysql.database saltenv=staging
salt-minion-mysql:
----------
          ID: mysql_package
    Function: pkg.installed
        Name: mysql-server
      Result: True
