So the users do not have to install it on their own. + +In case the users want to deploy Holmes independently, the steps for the installation is as follows. + +Prerequisites +^^^^^^^^^^^^^ + +#. MSB must be installed and started. The user knows the IP address of the MSB API gateway service. +#. PostgreSQL must be installed and started. For the guidance on how to run a PostgreSQL, please refer to `Offical Repository of PostgreSQL <https://hub.docker.com/_/postgres/>`_. + + **While setting up PostgreSQL, a database and a user named 'holmes' must be created. The corresponding password shuold be set to 'holmespwd'. Otherwise, Holmes could not be started up successfully.** + +Steps +^^^^^ + +#. Start the rule management module of Holmes using the command below: + + ``sudo docker run --name holmes-rule-management -p 9101:9101 -d -e URL_JDBC=$DB_IP -e MSB_ADDR=$MSB_IP -e TESTING=1 nexus3.onap.org:10001/onap/holmes/rule-management`` + +#. Start the engine manamgement module of Holmes using the command below: + + ``sudo docker run --name holmes-engine-management -p 9102:9102 -d -e URL_JDBC=$DB_IP -e MSB_ADDR=$MSB_IP -e TESTING=1 nexus3.onap.org:10001/onap/holmes/engine-management`` + +When the environment variable ``TESTING`` is set to ``1``, it means Holmes is running in the standalone mode. All the interactions between Holmes and other ONAP components are routed by MSB. + +Check the Status of Holmes +^^^^^^^^^^^^^^^^^^^^^^^^^^ + +After the installation, you have to check whether Holmes is alive or not using the health-check API. + +#. Use ``curl http://${msb-ip}:${msb-port}/api/holmes-rule-mgmt/v1/healthcheck`` or any other tools (e.g. Postman) to check whether the rule management module of Holmes has been spun up and registered to MSB successfully. + +#. Use ``curl http://${msb-ip}:${msb-port}/api/holmes-engine-mgmt/v1/healthcheck`` or any other tools (e.g. Postman) to check whether the engine management module of Holmes has been spun up and registered to MSB successfully. + +If the response code is ``200`` and the response body is ``true``, it's telling the user that everything is fine. Otherwise, you have to take a look at the logs to check whether there are any errors and contact the Holmes team for help. + |
