## Kafka Quickstart
|
||||
|
||||
Note that obp with kafka connector will also need a bank backend connected to the kafka that implements the following: https://apiexplorersandbox.openbankproject.com/glossary#Adapter.Kafka.Intro
|
||||
|
||||
Otherwise obp will display anything but adapter errors.
|
||||
|
||||
#####Configuration

* Edit the OBP-API/obp-api/src/main/resources/props/default.props so that it contains the following lines:
|
||||
|
||||
connector=kafka_vMay2019
|
||||
# kafka server location, plaintext for quickstart

kafka.host=localhost:9092

kafka.response_topic=Response
|

# number of partitions available on kafka. Must match the kafka configuration!!!!!!.

# no ssl for quickstart

## Kafka (optional):
|
||||
|
||||
If Kafka connector is selected in props (connector=kafka), Kafka and Zookeeper have to be installed, as well as OBP-Kafka-Python (which can be either running from command-propmpt or from inside Docker container):
|
||||
|
||||
* Kafka and Zookeeper can be installed using system's default installer or by unpacking the archives (http://apache.mirrors.spacedump.net/kafka/ and http://apache.mirrors.spacedump.net/zookeeper/)
|
||||
|
||||
* OBP-Kafka-Python can be downloaded from https://github.com/OpenBankProject/OBP-Kafka-Python
|
||||
|
||||
## Running with a Zookeeper/Kafka Cluster
|
||||
|
||||
1) NGINX Configuration for Load Balancing
|
||||
|
||||
* Create file /etc/nginx/sites-available/api
|
||||
|
||||
* Configure as follows:
|
||||
|
||||
upstream backend {
|
||||
least_conn;
|
||||
server host1:8080; # The name of the server shall be changed as appropriate
|
||||
server host2:8080;
|
||||
server host3:8080;
|
||||
}
|
||||
|
||||
server {
|
||||
server_name obptest.com www.obptest.com; # The server name should be changed as appropriate
|
||||
access_log /var/log/nginx/api.access.log;
|
||||
error_log /var/log/nginx/api.error.log;
|
||||
location / {
|
||||
proxy_pass http://backend/;
|
||||
}
|
||||
location /obp/v2.1.0/sandbox/data-import {
|
||||
proxy_pass http://backend/;
|
||||
}
|
||||
}
|
||||
|
||||
2) Zookeeper/Kafka Cluster Setup
|
||||
|
||||
* The Zookeeper/Kafka cluster is deployed on 3 nodes. The following configurations need to be done on each of the three nodes
|
||||
|
||||
* Zookeeper configuration
|
||||
|
||||
* Inside the Kafka directory, edit the file conf/zookeeper.properties and include these lines:
|
||||
|
||||
dataDir=/home/user/zookeeper
|
||||
server.1=host1:2888:3888 # The name of the servers shall be changed as appropriate
|
||||
server.2=host2:2888:3888
|
||||
server.3=host3:2888:3888
|
||||
initLimit=5
|
||||
syncLimit=2
|
||||
|
||||
* Create a myid file under dataDir which is /home/user/zookeeper in this example:
|
||||
|
||||
echo “1” > /home/user/zookeeper/myid #Insert unique id’s on each of the machines
|
||||
|
||||
* Start the zookpeer daemons on each of the 3 machines
|
||||
|
||||
bin/zookeeper-server-start.sh config/zookeeper.properties &
|
||||
|
||||
* Kafka Configuration
|
||||
|
||||
* Inside the Kafka directory, edit the file conf/server.properties and include these lines:
|
||||
|
||||
broker.id=1 # The broker.id should be unique for each host
|
||||
|
||||
num.partitions=4
|
||||
|
||||
zookeeper.connect=host1:2181,host2:2181,host3:2181
|
||||
|
||||
* Start the kafka broker daemons on all the machines:
|
||||
|
||||
bin/kafka-server-start.sh config/server.properties &
|
||||
|
||||
* Create the topics:
|
||||
|
||||
bin/kafka-topics.sh --create --zookeeper host1:2181,host2:2181,host3:2181 --replication-factor 1 --partitions 1 --topic Request
|
||||
|
||||
bin/kafka-topics.sh --create --zookeeper host1:2181,host2:2181,host3:2181 --replication-factor 1 --partitions 1 --topic Response
|
||||
|
||||
3) OBP-API
|
||||
|
||||
* Configuration
|
||||
|
||||
* Edit the OBP-API/obp-api/src/main/resources/props/default.props so that it contains the following lines. Please note that
|
||||
kafka.host is used by the producer and kafka.zookeeper_host is used by the consumer. This should be done on each node:
|
||||
|
||||
connector=kafka
|
||||
# Address to be used by consumer
|
||||
kafka.zookeeper_host=localhost:2181
|
||||
# Address to be used by producer
|
||||
kafka.host=localhost:9092
|
||||
kafka.request_topic=Request
|
||||
kafka.response_topic=Response
|
||||
|
||||
* Start the server:
|
||||
|
||||
cd OBP-API/obp-api/
|
||||
mvn jetty:run
|
||||
|
||||
4) OBP-Kafka-Python
|
||||
|
||||
* Run from the command line:
|
||||
|
||||
cd OBP-Kafka-Python
|
||||
python server.py
|
||||
|
||||
5) To test the setup, try a request
|
||||
|
||||
http://localhost:8080/obp/v2.0.0/banks
