Nifi starts without error but cannot connect

[#1]

Hi

I am very new to nifi and try to install and configure the system.

I started nifi.sh start and it shows 

Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home

NiFi home: /Users/daniel/Downloads/nifi-1.15.3

Bootstrap Config File: /Users/daniel/Downloads/nifi-1.15.3/conf/bootstrap.conf

And when i enter nifi.sh  status, terminal shows:

2022-02-26 09:31:33,238 INFO [main] org.apache.nifi.bootstrap.Command Apache NiFi is currently running, listening to Bootstrap on port 52929, PID=74313

I changed nifi.web.http.port in nifi.properties to 8080.

But still I do not see any on localhost:8080.

In the log file there is no message that server has started on 8080 port.

I have no idea what problem caused the issue.

Please advise me.

Thanks

Hi @CookieCream 

NiFi in the latest version is deployed automatically with security and TLS enabled.

You need to set the single user credentials and connect to port 8443 instead of 8080.

Please check the documentation: https://nifi.apache.org/docs/nifi-docs/html/getting-started.html#i-started-nifi-now-what

Cheers

Hi @araujo 

Thanks for the advice

I made the http post empty and re-launched the nifi but still have an issue.

On nifi-app.log file, I found the the following error message which I have no idea how to solve.

Please advise me.

@CookieCream ,

What do you mean by "made the http post empty"?

I would suggest that you remove your NiFi directory and restart from scratch following these instructions:

https://nifi.apache.org/docs/nifi-docs/html/getting-started.html#downloading-and-installing-nifi

If you follow the exact instructions the installation should work without problems.

Cheers,

André

@araujo 

I did as you advised; remove the existing NiFi directory and start from scratch as instruction states.

But as I start nifi.sh, the same error message shows on the log 😞

[#6]

@CookieCream ,

Which Java version to you have in your machine?

Could you please run the following command and provide the output?

java -version

Cheers,

André

[#7]

@araujo 

java version "1.8.0_65"

Java(TM) SE Runtime Environment (build 1.8.0_65-b17)

Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

Thanks

Daeyong

@CookieCream ,

Try these steps below after you delete your current nifi directory:

wget "https://downloads.apache.org/nifi/1.15.3/nifi-1.15.3-bin.tar.gz" -P .
tar -zxvf ./nifi-1.15.3-bin.tar.gz
cd nifi-1.15.3
./bin/nifi.sh set-single-user-credentials admin supersecret1
./bin/nifi.sh start

I just tested this on my laptop and it works without problems.

Cheers,

André

@CookieCream 

Did the above work?

@araujo 

I really appreciate for your help but unfortunately not working 😞

Still see the same error on nifi-app.log file.
