Stage 8 - Upgrade JanusGraph (0.5.3 -> 1.0.0)

Stage 8 - Upgrade JanusGraph (0.5.3 -> 1.0.0)

Objective

Upgrade JanusGraph from 0.5.3 to 1.0.0.

Prerequisites

  1. Ensure previous stages have been completed without error.

  2. Run the following command to confirm Janusgraph service is not running.

    systemctl --type=service --state=inactive,failed | grep 'janusgraph'

    The output should be similar to as shown below:

    janusgraph.service loaded inactive dead janusgraph.service

    If not, stop the service:

    sudo systemctl stop janusgraph

Steps

Deploy JanusGraph (JG)

  1. cd to the janusgaph_setup package’s bin directory:

    cd ~/syndeia-cloud-3.6*_janusgraph_setup/bin

  2. Run the JanusGraph (JG) pre-setup script. This will download and install/upgrade JanusGraph 1.0.0 or install/upgrade a pre-downloaded JanusGraph 1.0.0:

  1. Run the (main) JanusGraph (JG) setup script in upgrade mode. This will configure JanusGraph to work with Syndeia Cloud while preserving the syndeia_cloud_graph and syndeia_cloud_graph_config keyspaces:

./syndeia-cloud-3.6_janusgraph_setup.bash --upgrade
[jdoe@new-server bin]$ ./syndeia-cloud-3.6_janusgraph_setup.bash PURPOSE: This script will configure JanusGraph for use with Syndeia Cloud 3.6 Specifically this will: 1. Create/update janusgraph-current symlink to specified version, default = 1.0.0 2. Create a new syndeia_admin superuser in Cassandra with a password you specify 3. Create a new syndeia_cloud_graph and syndeia_cloud_graph_config keyspaces 4. GRANT ALL PERMISSIONS ON KEYSPACE syndeia_cloud_graph TO syndeia_admin 5. GRANT ALL PERMISSIONS ON KEYSPACE syndeia_cloud_graph_config TO syndeia_admin 6. Create a renamed copy of the file /opt/janusgraph-<release_ver>/conf/janusgraph-cql-configurationgraph.properties as janusgraph-cql-configurationgraph-syndeia.properties with: graph.graphname=syndeia_cloud_graph_config Add storage.username=syndeia_admin Add storage.password=<password_specified> storage.hostname=<your_cassandra_jg_host> 6. If you installed Elasticsearch on the same machine, add index.search.backend=elasticsearch and index.search.hostname=localhost to use Elasticsearch for search indexing 7. Create a renamed copy of the file /opt/janusgraph-<release_ver>/conf/gremlin-server/gremlin-server-configuration.yaml as gremlin-server-configuration-syndeia.yaml and set ConfigurationManagementGraph to point to janusgraph-cql-configurationgraph-syndeia.properties. 9. Install systemd .service file for JanusGraph service 10. Start JanusGraph service 11.

Note, the current password for the Cassandra admin when installed via the pre-setup script is the Cassandra project’s documented default, ie: cassandra, we recommend changing this via CQLSH once SC deployment has been successfully completed (see Appendix B2.11 for instructions on how to do this), especially if the Cassandra node will (eventually) be exposed in a multi-node topology.

Verification

  1. Check the status of the Janusgraph server. To check the status of the JanusGraph service, use the following command.

    sudo systemctl status janusgraph

    You can verify that it started if, Active: active (running) shows up in the output.

  2. Verify JG client can communicate with the server by running the Gremlin client, ie:

    /opt/janusgraph-current/bin/gremlin.sh

    Then execute the following commands after it starts up:

    :remote connect tinkerpop.server conf/remote.yaml session :remote console graph = ConfiguredGraphFactory.open('syndeia_cloud_graph'); // should return: ==>standardjanusgraph[cql:[cassandra.mydomain.com]]
    g = graph.traversal(); g.V(); g.E(); // The last 2 commands above should return results since the graph (syndeia_cloud_graph) DB is presumably not empty, ie: vertices and edges are present.

    To quit type:

    :quit
