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 lint online, we using 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.
