The `mariadb-replication-setup` project is designed to deploy `MariaDB master-slave replication clusters` on `Ubuntu` (both `focal`, `jammy`, `mantic`). This solution is tailored for use on dedicated physical servers, virtual machines, and within both on-premises and cloud-based infrastructures.

This project currently only facilitates the `creation` of new clusters.

4. Edit the variable file vars/main.yml

```bash

nano vars/main.yml

```

Minimum set of variables:

- `mariadb_version`

- `mariadb_replication_user` # user to connect to the Master server and request binary logs

- `mariadb_replication_password`

- (Optional) `create_user` # if set to `true`, create new user. must fill `mariadb_user`, `mariadb_password`, `mariadb_host`

5. Try to connect and ping to all hosts

```bash

ansible all -m ping

```

6. Run playbook

```bash

ansible-playbook deploy_cluster.yml

```
