If you are using an SSL-enabled, MySQL database for Ranger, add the following properties to install.properties:

db_ssl_enabled=false
db_ssl_required=false
db_ssl_verifyServerCertificate=false
javax_net_ssl_keyStore=

javax_net_ssl_trustStorePassword=

If Ranger Admin is SSL-enabled, add the following Ranger Admin SSL properties to the install.properties file. These properties secure the Ranger SSL password in the jceks file.

policymgr_https_keystore_file=<SSL keystore file path used to configure Ranger in SSL>
policymgr_https_keystore_keyalias=rangeradmin
policymgr_https_keystore_password=<SSL password used to create keystore>

If Unix-Auth and User-Sync service is SSL-enabled, add the following Ranger Unix-Auth SSL properties to the install.properties file:

ranger_unixauth_keystore=keystore.jks
ranger_unixauth_keystore_password=password
ranger_unixauth_truststore=cacerts
ranger_unixauth_truststore_password=changeit

The RANGER_PID_DIR_PATH property introduces a custom PID path for the Ranger Admin Process. To configure this property to start and stop the Ranger Admin service, add the following property to install.properties. The default value is /var/run/ranger.
