Closing Windows CMD kills Solr

[Steven White]

Hi Folks,

I don't understand if this is an expected behavior or not.

On Windows, I start Solr from a command prompt like so:

bin\solr start -p 8983 -s C:\MySolrIndex

Now, once I close the command prompt the Java process that started Solr is
killed. is this expected? How do I keep Solr alive when I close the
command prompt?

This dose not happen on Linux.

Thank in advanced.

Hi Steve,

This is expected behaviour.

I get around this by creating a scheduled task, set to run at startup to start Solr.

Hope this helps

Alan

Yes, this is expected behaviour. If you want to prevent it you either
need to keep the command window open, or run Solr as a Windows Service
(kinda like a Unix daemon, but more annoying). To do the latter I would
recommend NSSM - here are some links that will help:

(from step 2)

Yes, this is the expected behaviour. Once you close the command window,
Solr will stop running. This has happened to me several times. Just to
check, which version of Solr are you using?

I have tried NSSM before, and it works for Solr 5.0 and Solr 5.1. However,
when I move up to Solr 5.3.0, I wasn't able to use the same method to start
it as a service using NSSM.

Do let me know if you managed to set up NSSM for Solr 5.3.0?

Regards,
Edwin
