sql-server-samples/samples/features/high availability/Linux/Ansible Playbook

This is a sample Ansible playbook that shows how to install SQL Server, create a Pacemaker cluster, and create an AG managed by the cluster on a set of Linux nodes.

Roles

• pacemaker - This role creates a Pacemaker cluster between the hosts.
• mssql-server - This role installs SQL Server on the host, runs setup to set the SA password, and starts the service.
• mssql-server-ha - This role enables support for HA and creates a DB Mirroring endpoint.
• mssql-server-ag-external - This role installs the Pacemaker resource agents, creates an AG, an optional listener, and Pacemaker resources for both.

Try

1. Put the names of the Linux nodes in the inventory file

2. Configure the deployment in play.yml

3. Create a vault file named vault.yml using the template at the end of this README.

   ansible-vault create vault.yml
   

4. Execute the playbook

   ansible-playbook ./play.yml -i ./inventory --ask-vault-pass -e 'ansible_user=username'
