(Re)starting the Extraction Browser Web Demo on Reliable
Restarting the Servlet Process
- Log in to reliable as knowall
- check that a screen called 'extractionBrowser' is not already running. If it is, switch to it (using command 'screen -r extractionBrowser') and skip the next step.
- run the command 'screen -S extractionBrowser'.
- run the command 'java -jar ~/web/jetty/jetty-distribution-8.0.4.v20111024/webapps/extractionbrowser-1.0.0-jetty-console.war --port 8088'. This will start the extraction browser servlet listening on port 8088 (openie.cs forwards requests to reliable.cs:8088)
- If everything works normally, stdout should display a small amount of output ending with the text "STARTING", without any error messages or stack traces. At this point, the Servlet is ready to serve demo requests.
- Verify that you can see the demo at http://openie.cs.washington.edu and http://reliable.cs.washington.edu:8088
- Detach the screen session by pressing Control-a d.
Restarting memcached
- Log in to reliable as knowall (if you haven't already)
- Check that memcached is not already running with the command 'ps aux | grep memcached'. If memcached is running, you will see a process that looks like knowall 17054 0.0 0.0 341780 16836 ? Ssl 01:10 0:00 ./memcached -d -m 2048 -l 128.95.1.229 -p 11211
- If memcached is already running, kill it using the command 'kill <pid>' where <pid> is memcached's PID.
- Start a new memcached daemon process by running the command '/home/knowall/local/opt/memcached/bin/memcached -d -m 2048 -l `hostname --ip` -p 11211'
- Verify that both the demo and memcached are working properly by checking that demo queries either report "cache miss" or "from cache" when returning results.
Note: Extraction Browser should automatically restart itself under knowall on the machine reliable in the event of a reboot, due to the following crontab entries: (current as of 12/23/2011)
- @reboot screen -dmS extractionBrowser java -jar ~/web/jetty/jetty-distribution-8.0.4.v20111024/webapps/extractionbrowser-1.0.0-jetty-console.war --port 8088
- @reboot /home/knowall/local/opt/memcached/bin/memcached -d -m 2048 -l `hostname --ip` -p 11211
Bug List
- Search for argument1:"United States" overconstrains the results.
