Key/Value Store on Terra and Swarmnuc2008

On terra.eecs.berkeley.edu, we are running the $PTII/ptolemy/actor/lib/jjs/modules/httpServer/demo/KeyValueStoreClient/KeyValueStoreServerTerra.xml model.

We have a similar setup running on swarmnuc2008.eecs.berkeley.edu, see $PTII/org/terraswarm/accessor/demo/AugmentedRealityVideoSOHO/README.txt

On terra.eecs.berkeley.edu, the way the model gets started is by using pm2 in the sbuser account.

On terra, ~sbuser/runKVStore contains

#!/bin/sh
# pm2 start  --interpreter=bash ~/runKVStore
$PTII/bin/ptinvoke ptolemy.moml.MoMLSimpleApplication $PTII/ptolemy/actor/lib/jjs/modules/httpServer/demo/KeyValueStoreClient/KeyValueStoreServerTerra.xml

On swarmnuc2008, ~sbuser/runKVStore contains:

#!/bin/sh
# pm2 start  --interpreter=bash ~/runKVStore
$PTII/bin/ptinvoke ptolemy.moml.MoMLSimpleApplication $PTII/org/terraswarm/accessor/demo/AugmentedRealityVideoSOHO/KeyValueStoreServerSOHO.xml

PM2 Installation Instructions

  1. As the sbuser, install pm2
      cd
      mkdir node_modules
      npm   install pm2
      export PATH=~/node_modules/bin:${PATH}
    You may want to add the export line to sbuser's ~/.bashrc.
  2. As root, run the command below to set up pm2 to start up on reboot
      export PATH=/home/sbuser/src/ptII/bin:${PATH}
      export PTII=/home/sbuser/src/ptII
    ~sbuser/node_modules/.bin/pm2 startup
  3. As sbuser, create the ~sbuser/runKVStore file (see above for the contents) and make it executable:
      chmod a+x ~/runKVStore
  4. As sbuser, create ~sbuser/sbuser.cron (see above).
  5. As sbuser, have pm2 start up our script:
      pm2 start  --interpreter=bash ~/runKVStore
  6. As sbuser, run the startup command to register the sbuser account:
    sbuser@swarmnuc2008:~/.pm2/logs$ pm2 startup
    /home/sbuser/src/ptII/bin/node: Running /usr/bin/node /home/sbuser/node_modules/.bin/pm2 startup
    [PM2] Init System found: systemd
    [PM2] To setup the Startup Script, copy/paste the following command:
    sudo env PATH=$PATH:/usr/bin /home/sbuser/node_modules/pm2/bin/pm2 startup systemd -u sbuser --hp /home/sbuser
    It might not be necessary to run the above command, but it probably does not hurt.
  7. As root, run the setup command:
      sudo env PATH=$PATH:/usr/bin /home/sbuser/node_modules/pm2/bin/pm2 startup systemd -u sbuser --hp /home/sbuser
  8. As sbuser, save the current setup:
    sbuser@swarmnuc2008:~/.pm2/logs$ pm2 save
    /home/sbuser/src/ptII/bin/node: Running /usr/bin/node /home/sbuser/node_modules/.bin/pm2 save
    [PM2] Saving current process list...
    [PM2] Successfully saved in /home/sbuser/.pm2/dump.pm2
    sbuser@swarmnuc2008:~/.pm2/logs$

Firewall

The port is currently 8099. To change the port edit the model and then update the firewall. See https://www.terraswarm.org/swarmos/wiki/Main/TerraAndTerraTest#toc13

Restarting

We restart the model every day so as to avoid memory leaks and other failures

~sbuser/sbuser.cron contains:

1 5 * * *  cxh -c '/home/sbuser/cg/node_modules/.bin/pm2 restart runKVStore' >& /home/sbuser/runKVStore.log

To update the crontab use:

crontab ~/sbuser.cron
