Kafka Token Authentication Mechanism Tool Usage¶
Scenario¶
Operations need to be performed on tokens when the token authentication mechanism is used.
Prerequisites¶
The system administrator has understood service requirements and prepared a system user.
The Kafka client has been installed.
Procedure¶
Log in as a client installation user to the node on which the Kafka client is installed.
Switch to the Kafka client installation directory, for example, /opt/kafkaclient.
cd /opt/kafkaclient
Run the following command to configure environment variables:
source bigdata_env
Run the following command to perform user authentication (skip this step in normal mode):
kinit Component service user
Run the following command to switch to the Kafka client installation directory:
cd Kafka/kafka/bin
Use kafka-delegation-tokens.sh to perform operations on tokens.
Generate a token for a user.
./kafka-delegation-tokens.sh --create --bootstrap-server <IP1:PORT, IP2:PORT,...> --max-life-time-period <Long: max life period in milliseconds> --command-config <config file> --renewer-principal User:<user name>
Example: ./kafka-delegation-tokens.sh --create --bootstrap-server 192.168.1.1:21007,192.168.1.2:21007,192.168.1.3:21007 --command-config ../config/producer.properties --max-life-time-period -1 --renewer-principal User:username
List information about all tokens of a specified user.
./kafka-delegation-tokens.sh --describe --bootstrap-server <IP1:PORT, IP2:PORT,...> --command-config <config file> --owner-principal User:<user name>
Example: ./kafka-delegation-tokens.sh --describe --bootstrap-server 192.168.1.1:21007,192.168.1.2:21007,192.168.1.3:21007 --command-config ../config/producer.properties --owner-principal User:username
Update the token validity period.
./kafka-delegation-tokens.sh --renew --bootstrap-server <IP1:PORT, IP2:PORT,...> --renew-time-period <Long: renew time period in milliseconds> --command-config <config file> --hmac <String: HMAC of the delegation token>
Example: ./kafka-delegation-tokens.sh --renew --bootstrap-server 192.168.1.1:21007,192.168.1.2:21007,192.168.1.3:21007 --renew-time-period -1 --command-config ../config/producer.properties --hmac ABCDEFG
Destroy a token.
./kafka-delegation-tokens.sh --expire --bootstrap-server <IP1:PORT, IP2:PORT,...> --expiry-time-period <Long: expiry time period in milliseconds> --command-config <config file> --hmac <String: HMAC of the delegation token>
Example: ./kafka-delegation-tokens.sh --expire --bootstrap-server 192.168.1.1:21007,192.168.1.2:21007,192.168.1.3:21007 --expiry-time-period -1 --command-config ../config/producer.properties --hmac ABCDEFG
