I installed elasticsearch. While installing Kibana I am facing the below error:

.

Please assist

Hi @ishan.abhinit,

Welcome to our community! Can you provide a bit more details? What is in your kibana.yml, please post hiding any sensitive data? Also how are you installing ELK and which version?

Thanks,
Liza

Yes, I am installing ELK 7.6.2 on CentOS7 from here:
https://www.elastic.co/guide/en/elastic-stack-get-started/current/get-started-elastic-stack.html

Thanks @ishan.abhinit, it looks like you downloaded the tar file and are running it as ./bin/kibana.

Is it possible you unzipped and untared the Kibana packaged as root or a different user than the user you are running as, this would cause the permission issue you are seeing. Please check and let us know.

[ishan.abhinit (ishan)]

I just used sudo to untar the package.
Then I executed the command using sudo and looks like it is working. But now I am getting a new error and a warning.

I read a bit about x-pack and looks like x-pack is installed by default on elasticsearch 7.6.2 and kibana 7.6.2. So I am not sure what this warning is about?

Hi @ishan.abhinit,

If you are using default it should come up with basic license, have you made any updates to the elasticsearch.yml or kibana.yml? Please ensure that both packages are for 7.6.2.

Thanks,
Liza

No, I haven't made any changes to both the yml files. I previously had version 2.4.6 of ELK installed on this machine. Looks like that is what is interfering with the settings. Before downloading the latest version (7.6.2) I had removed the older one but still the problem persists.
Also the below command shows me the older version--> curl http://127.0.0.1:9200

Hi @ishan.abhinit,

It looks like your old installation is still running on port 9200, can you search for and terminate the process associated with that? Also, elasticsearch will bind to another port if the default 9200 is in use, so if you started your newer installation you can get the port from the elasticsearch log. Hope this helps.

Thanks,
Liza
