Nifi Processor group startup along with the Nifi
Hi Team,
we have installed Nifi-1.9.2, 2-node cluster in our lab and tried to test
how to start the nifi processor group along with the nifi startup. Here is
the following way we tried:
1. Configured nifi as a service in our lab and created the python program
where it contains the curl command to start the nifi process group and
given that is given in the execstartpost option
Here is the service configuration file:
path: /etc/systemd/system/nifi.service
[Unit]
Description=Apache NiFi
After=network.target
[Service]
Type=forking
User=root
Group=root
ExecStart=/opt/nifi-1.9.2/bin/nifi.sh start
#ExecStartPost=/usr/bin/python /root/samplecurlcode_cluster.py
ExecStop=/opt/nifi-1.9.2/bin/nifi.sh stop
ExecRestart=/opt/nifi-1.9.2/bin/nifi.sh restart
[Install]
WantedBy=multi-user.target
****
Can you please suggest to us do we have any other option to start the nifi
processor group along with nifi startup.
or if need to proceed with the above way am getting the TimedOut Error when
i execute the below command.
Command: systemctl start nifi
Error:

It would be really cool if we offered a "hook" as part of the bootstrap
process which would allow for a script to be ran that did things like this
once NiFi was "started". Here the script could be user and environment
defined and startup the desired processors/controller services.

Re: Nifi Processor group startup along with the Nifi

You can use Nifi CLI
<https://nifi.apache.org/docs/nifi-docs/html/toolkit-guide.html#nifi_CLI>
for starting a processor group. We use the Nifi Registry to get the latest
flow and then deploy and start the processor group needed.
Thanks,
