Configure the UI

Find details here for the configuration properties of the UI. Properties are defined in the following file:

/etc/wandisco/ui/application-prod.properties

When adding new properties or changing existing values, restart the Data Migrator service.

General configuration

Configure how the UI is run overall.

Name	Details
server.port	Set the port on which the UI will be available. This is overridden by the server.ssl.port when TLS is enabled. Default value: 8081 Allowed values: An integer value between 1024 and 65535

UI logging

The UI configuration file (/etc/wandisco/ui/application-prod.properties) contains the following logging configuration properties:

Name	Details
logging.output.path	The output path for all logging. Default value: /var/log/wandisco/ui Allowed values: The full path to a valid directory that is writable by the user running the UI. The user is typically hdfs.
logging.level.ROOT	The log level. Default value: INFO Allowed values: A valid log level: TRACE, DEBUG, INFO, WARN, ERROR, FATAL, or OFF.
logging.audit.output.filename	The output filename for the audit log. This will be suffixed with the date in YYYY-MM-DD format. Default value: livedata_ui_audit Allowed values: A valid string.
logging.audit.days-kept	The amount of days that the audit log will be retained. Default value: 90 Allowed values: An integer value for the number of days that logs are kept.

Configure the log output path for the UI

1. Open /etc/wandisco/ui/application-prod.properties.
2. Edit the following line, replacing the default path /var/log/wandisco/ui with your own. For example:

   logging.output.path=/your/path/here
3. Save the change.
4. Restart Data Migrator.

Reset admin user password

Reset the admin user's password for Data Migrator by creating a file named reset.password in the UI configuration directory (/etc/wandisco/ui/ by default).

Add the existing email value and a new password value in the file (The password must conform to the same password requirements as the UI) :

email=user@domain.com
password=newPassword

Restart the UI server after the file has been created. When the UI restarts, it updates the password to the value entered in the file, the file is then automatically deleted.

note

This process cannot be used for users other than the admin. It does not work for the admin user's email address, which cannot be changed.

Security

Basic authentication compatibility

If basic authentication is enabled on Data Migrator or Hive Migrator (or both), the following additional steps are required to maintain UI functionality: Update basic auth in the UI.

TLS

Configure how the UI uses TLS, which is disabled by default.

Name	Details
server.ssl.enabled	Set to true to enable TLS. If no other TLS values are set, this will use an internal keystore and a self-signed certificate to serve the UI. Default value: false Allowed values: true, false
server.ssl.port	Set the port on which the UI should be available when TLS is enabled. Default value: 8443 Allowed values: An integer value between 1024 and 65535
server.ssl.key-store	The path to the key store which should be used instead of the internal default
server.ssl.key-store-password	The password to be used to access the key store
server.ssl.key-alias	The alias of the certificate to be used
server.ssl.key-store-type	Optional: set the key store type. Defaults to PKCS12
application.liveMigratorV2.client.noCheckCertificate	Optional: add this property and set the value to true if you want to implicitly trust certificates from remote Data Migrator instances. Default value: false Instead of using this property, we recommend that you import your server certificate into a truststore.

tip

The example command below will import a certificate file, certificate-file.crt into the Java truststore cacerts:

keytool -importcert -file /etc/wandisco/certificate-file.crt -keystore cacerts -alias key-alias

For more information about parameters, see Oracle's documentation.

Using a custom truststore (UI)

The default SSL keystore configuration for the UI is stored in /etc/wandisco/ui/application-prod.properties:

server.ssl.port=8443
server.ssl.enabled=true
server.ssl.key-store=/etc/wandisco/ui/tls/keystore.p12
server.ssl.key-store-password=password
server.ssl.key-store-type=PKCS12
server.ssl.key-alias=livedata-ui

note

If you define a custom keystore using these configuration parameters, the truststore will still default to the one in the JAVA home directory.

For more information, see Transport Layer Security (TLS).

Use the following steps to enter a custom truststore:

1. Open /etc/wandisco/ui/vars.env in a text editor.
2. Add the following line:

   LDUI_EXTRA_JVM_ARGS="-Djavax.net.ssl.trustStore=/etc/wandisco/ui/tls/keystore.p12 -Djavax.net.ssl.trustStorePassword=password"
   This UI extra JAVA argument adds the following:

• Djavax.net.ssl.trustStore - Path to the custom truststore file.
• Djavax.net.ssl.trustStorePassword - The custom truststore password.

3. Save the change.
4. Restart the UI service. using the command:

   systemctl restart livedata-ui

Data Migrator instance

Default Data Migrator instance hostname and port /etc/wandisco/ui/application-prod.properties:

application.liveMigratorV2.servers=localhost\:18080

Directory structure

The following directories are used for the UI:

Location	Content
/var/log/wandisco/ui	Logs
/etc/wandisco/ui	Configuration files
/opt/wandisco/ui	Operation files
/var/run/livedata-ui	Runtime files
