Installation: Setup resque pool

Notes

Resque-pool starts and manages a pool of resque workers that handle jobs like transcoding video files and retrieving metadata with fits, so your users can move on to the next page or the next upload while their jobs are in process.

Steps

To set resque-pool as a service:

1. Copy the pool_q script
   Ubuntu: sudo cp /opt/hydradam/script/pool_q /etc/init.d/
   CentOS: sudo cp /opt/hydradam/script/pool_q /etc/rc.d/init.d/
2. Set ownership on the script
   Ubuntu: sudo chown root:root /etc/rc.d/init.d/pool_q
   CentOS: sudo chown root:root /etc/init.d/pool_q
3. Set permissions on the script
   Ubuntu: sudo chmod 0755 /etc/rc.d/init.d/pool_q
   CentOS: sudo chmod 0755 /etc/init.d/pool_q
4. (CentOS Only) Add pool_q to chkconfig so it will start automatically on reboot
   sudo chkconfig --add pool_q

Verification Steps

1. Start a pool of resque workers:
   sudo service pool_q start
2. Wait 30 seconds for the pool master to spawn workers, then check the pool:
   ps aux | grep [r]esque
   You should see output something like this:

root  1428 ... 0:12 resque-pool-master[hydradam]: managing [1472, 1479, ...]  
root  1472 ... 0:04 resque-1.25.1: Waiting for video  
root  1479 ... 0:19 resque-1.25.1: Waiting for audio,audit,batch_update,characterize,event,ingest,templates,unzip,video
