    All the passwords entered in the properties file are encrypted when you start your Talend Dictionary Service instance.

  2. Update the following fields with your MongoDB settings:

    Field

    Description
    spring.data.mongodb.host Host name of your MongoDB instance. For example: localhost.
    spring.data.mongodb.port Port number of your MongoDB instance. For example: 27017.

    spring.data.mongodb.database Name of the database on which Talend Dictionary Service is connected, dqdict by default.
    spring.data.mongodb.uri URI of the MongoDB instance to connect to

    If you connect to the MongoDB instance using a URI, the following parameters must be commented out: dq.mongo.host, dq.mongo.port, dq.mongo.username, dq.mongo.password, dq.mongo.database.name

    Information noteImportant: This configuration parameter is available only if you have installed the TPS-4354 patch delivered by Talend. For more information, check with your administrator.
    spring.data.mongodb.ssl Default value is false, put to true if you need to use the Secure Socket Layer protocol with MongoDB
    spring.data.mongodb.ssl.trust-store Trust store location.
    spring.data.mongodb.ssl.trust-store-password Trust store password.

    Password is encrypted upon startup.
  3. Launch MongoDB.
  4. Locate the file semantic-dictionary-import.sh.
  5. Open this file with an editor and update the placeholders:

  8. Make this file executable by running the following command: 
    chmod +x semantic-dictionary-import.sh
  9. Start Talend Dictionary Service by launching, in this order:
    1. Apache ZooKeeper
    2. Apache Kafka
    3. MinIO
