I want to stop solr by command so if find this article
http://rc98.net/solrinit
echo "Stopping Solr"
cd $SOLR_DIR
java -Xmx1024m -DSTOP.PORT=8079 -DSTOP.KEY=stopkey -jar start.jar --stop
what is Xmx1024m ?
and where i will find DSTOP.KEY ?
Please tell proper procedure to start and stop solr by command line.
-XmX1024m - is the java parameter and specifies the maximum java heap size, which in your case is set to 1 GB.
stopkey is a secret key on startup which must also be present on the termination request to enhance security.
You can find a detailed explanation @ http://docs.codehaus.org/display/JETTY/Securing+Jetty
Example -
Starting solr with Jetty -
java -DSTOP.PORT=8079 -DSTOP.KEY=mysecret -jar start.jar
Stopping Solr with Jetty -
java -DSTOP.PORT=8079 -DSTOP.KEY=mysecret -jar start.jar --stop
the STOP.KEY is the secret key which should match during the stop command.
solr stop -all # Stops all the ports
solr stop -p 8983 # Stop the particular port
If it shows the error ERROR: Port 8983 is already being used by another process., kill the console window which runs Solr by Ctrl-C and then try one of the above options. Because killing the console window does not stop the service.
You could run (where 8983 is the default solr port)
lsof -i :8983
which will return PID#, then use
kill -9 PID#
to kill that pid (run it without the hash)
This worked for me if rake sunspot:solr:stop doesn't work
ps -ef | grep solr
then using the information returned
sudo kill <process_id>
example:
sudo kill 792
For local operation, you can kill the Solr server by pressing Ctrl-c in the console window
in which you started Solr. Typically, this is safe enough for development and testing
