Run playbooks¶

Checking the integrity of the configuration files¶

Before running any playbook, check the integrity of the configuration files.

1. Ensure that all the files edited in the /etc/openstack_deploy directory are Ansible YAML compliant.

2. Check the integrity of your YAML files.

   Note

   To check your YAML syntax online, you can use the YAML Lint program.

3. Change to the /opt/openstack-ansible/playbooks directory, and run the following command:

   # openstack-ansible setup-infrastructure.yml --syntax-check
   

4. Recheck that all indentation is correct. This is important because the syntax of the configuration files can be correct while not being meaningful for OpenStack-Ansible.

Run the playbooks to install OpenStack¶

1. Change to the /opt/openstack-ansible/playbooks directory.

2. Run the host setup playbook:

   # openstack-ansible setup-hosts.yml
   

   Confirm satisfactory completion with zero items unreachable or failed:

   PLAY RECAP ********************************************************************
   ...
   deployment_host                :  ok=18   changed=11   unreachable=0    failed=0
   

3. Run the infrastructure setup playbook:

   # openstack-ansible setup-infrastructure.yml
   

   Confirm satisfactory completion with zero items unreachable or failed:

   PLAY RECAP ********************************************************************
   ...
   deployment_host                : ok=27   changed=0    unreachable=0    failed=0
   

4. Run the following command to verify the database cluster:

   # ansible galera_container -m shell \
     -a "mysql -h localhost -e 'show status like \"%wsrep_cluster_%\";'"
   

   Example output:

   node3_galera_container-3ea2cbd3 | success | rc=0 >>
   Variable_name             Value
   wsrep_cluster_conf_id     17
   wsrep_cluster_size        3
   wsrep_cluster_state_uuid  338b06b0-2948-11e4-9d06-bef42f6c52f1
   wsrep_cluster_status      Primary
   
   node2_galera_container-49a47d25 | success | rc=0 >>
   Variable_name             Value
   wsrep_cluster_conf_id     17
   wsrep_cluster_size        3
   wsrep_cluster_state_uuid  338b06b0-2948-11e4-9d06-bef42f6c52f1
   wsrep_cluster_status      Primary
   
   node4_galera_container-76275635 | success | rc=0 >>
   Variable_name             Value
   wsrep_cluster_conf_id     17
   wsrep_cluster_size        3
   wsrep_cluster_state_uuid  338b06b0-2948-11e4-9d06-bef42f6c52f1
   wsrep_cluster_status      Primary
   

   The wsrep_cluster_size field indicates the number of nodes in the cluster and the wsrep_cluster_status field indicates primary.

5. Run the OpenStack setup playbook:

   # openstack-ansible setup-openstack.yml
   

   Confirm satisfactory completion with zero items unreachable or failed.
