Nifi starts without error but cannot connect

CookieCream — Sat, 26 Feb 2022 17:38:09 GMT

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

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 😞

Re: Nifi starts without error but cannot connect

araujo — Wed, 02 Mar 2022 02:49:15 GMT

@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

Re: Nifi starts without error but cannot connect

@araujo

java version "1.8.0_65"

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

Here's your actual error:

2022-02-27 23:08:20,716 WARN [main] o.a.nifi.security.util.SslContextFactory Some truststore properties are populated (./conf/truststore.p12, ********, PKCS12) but not valid
2022-02-27 23:08:20,717 ERROR [main] o.apache.nifi.controller.FlowController Unable to start the flow controller because the TLS configuration was invalid: The truststore properties are not valid

Ensure that you have generated certificates (SSL in your case, i assume). Add them to the truststore.jks of your Nifi instance (default location: ./conf/). Also, ensure the truststore and keystore properties in nifi.properties is accurately updated.

This should help i guess.

Thanks

@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

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

CookieCream — Thu, 03 Mar 2022 05:49:15 GMT

Hi @snm1523

Thanks for the reply.

Could you tell me in more detail how to get the generated certificates? and I do not see truststore and keystone properties in nifi.properties.

Re: Nifi starts without error but cannot connect

araujo — Thu, 03 Mar 2022 06:32:48 GMT

That's really weird. I executed exactly the commands that I listed and it works for me.

Are you sure that you started in an empty directory?

What the OS of your computer?

Re: Nifi starts without error but cannot connect

CookieCream — Thu, 03 Mar 2022 06:38:12 GMT

@araujo

macOS Monterey v 12.2.1

Since the wget command did not work on the terminal, I directly enter the url and downloaded .tar file and follow exactly as you explained.

Thanks.

Re: Nifi starts without error but cannot connect

araujo — Thu, 03 Mar 2022 07:22:20 GMT

Can you please upload your nifi-app.log here?

Re: Nifi starts without error but cannot connect

araujo — Thu, 03 Mar 2022 07:24:47 GMT

And the nifi-bootstrap.log file as well, please.

Re: Nifi starts without error but cannot connect

CookieCream — Thu, 03 Mar 2022 07:33:08 GMT

@araujo

Do you know how to upload file? because it says "The file type (.log) is not supported."

Re: Nifi starts without error but cannot connect

araujo — Thu, 03 Mar 2022 07:36:01 GMT

Just rename the file to .txt and try to upload.

If it doesn't work, you can copy and paste the content in a Word document (.docx)

Re: Nifi starts without error but cannot connect

snm1523 — Tue, 08 Mar 2022 15:04:57 GMT

Hi @CookieCream,

Should guide you on how do we get certificates generated.

Apache NiFi Toolkit Guide

Once you have this followed and certs generated, you will have a new nifi.properties created that will include truststore and keystore related properties.

I have not tried anything on MacOS, but, I did saw there are some specific instructions for MacOS.

Have a look

Thanks
