Solr process 12855 from /var/solr/solr-8983.pid not found. How to fix this error

Answer 1

From the error message, it sounds like Solr was previously installed on the server. To fix this issue, Please list the processes running on the server. If you see any java process like one below then please kill those process.

root 12594 0.0 0.5 11979776 189300 ? Sl Nov07 0:57 /usr/bin/java -DSTOP.PORT=8079 -DSTOP.KEY=stopkey -jar start.jar root 15635 0.0 0.5 12041440 184348 ? Sl Nov07 0:52 /usr/bin/java -DSTOP.PORT=8079 -DSTOP.KEY=stopkey -jar start.jar

Now start the solar using the command

service solr start

This fixes the issue
