Let us learn how to do the Ansible mariadb replication with the support of our Redis of our server management support services at Bobcares.

MariaDB Replication with Ansible

We may use Ansible to automate the installation and administration of numerous infrastructure components, such as database systems like MariaDB.

In MariaDB, replication refers to the act of generating and maintaining several copies of a database, with changes made to the primary copy automatically propagating to the replicas.

How to configure MariaDB replication using Ansible?

We may use Ansible to configure MariaDB by following these general steps:

• Inventory Setup:

  a: Create an Ansible inventory file that contains a list of all the target hosts participating in the replication configuration.

  b: Assign each host proper host aliases or group names.
• Playbook Creation:

  a:Create an Ansible playbook that defines the required replication setup state.

  b:Configure the hosts and activities required for replication.
• Task Definitions:

  a:In the playbook, define tasks to do operations on the hosts, such as installing MariaDB, configuring the server, and establishing replication.

  b: Installing packages, updating configuration files, establishing users, giving rights, and running SQL queries are examples of tasks.
• MariaDB Replication Configuration:

  a:To configure MariaDB replication, use the relevant Ansible modules.

  b: For example, we may use the mysql_user module to establish replication user accounts and assign appropriate permissions.

  c: Configure replication settings using the mysql_replication module, which includes setting up the master and slave roles, defining replication user credentials, and choosing the replication type (e.g., statement-based, row-based, or mixed).
• Running the Playbook:

  a:Use the ansible-playbook command to run the Ansible playbook, passing the playbook and inventory files as arguments.

  b: Ansible will connect to the target hosts, complete the tasks specified, and establish MariaDB replication in accordance with the playbook instructions.

We can simply build and maintain MariaDB replication configurations across numerous servers by employing Ansible’s automation features.

Ansible allows us to describe the desired state of the infrastructure, making consistency and ensuring that the replication setup remains in the intended configuration easy.
