---------------
Installing |cp|
---------------

After you configure the ``hosts.yml`` file, to install or update all |cp|
components, run the ``all.yml`` playbook:

::
      
   ansible-playbook -i hosts.yml all.yml

Install individual components, using the Ansible tags. You must follow the
correct order given below to satisfy the dependencies among the components. For
example, |ak| will not install until the certificate authority is generated and
|zk| is installed.

Similarly, when you update a component section in the ``hosts.yml`` file, you can optionally update the component and the preceding components in the order.

1. Generate the certificate authority (CA) if TLS encryption is enabled and using self-signed certificates.

::
  
     ansible-playbook -i hosts.yml all.yml --tags=certificate_authority
 
2. Install |zk|.

:: 
  
    ansible-playbook -i hosts.yml all.yml --tags=zookeeper
 
3. Install |ak|.

::
  
  ansible-playbook -i hosts.yml all.yml --tags=kafka_broker
 
4. Install |sr|, |crest|, |kconnect|, and KSQL in any order.

::
  
   ansible-playbook -i hosts.yml all.yml --tags=schema_registry
   ansible-playbook -i hosts.yml all.yml --tags=kafka_rest
   ansible-playbook -i hosts.yml all.yml --tags=kafka_connect
   ansible-playbook -i hosts.yml all.yml --tags=ksql
 
5. Install |c3-short|.

::
  
   ansible-playbook -i hosts.yml all.yml --tags=control_center
