Set up a new CDN

CDN on VTN - headnode

  1. nova flavor-create --is-public true m1.cdnnode auto 8192 110 4
  2. in XOS create flavor m1.cdnnode and add to deployment

CDN on VTN - CMI

  1. Make sure plenty of glance space on ctl node
  2. Make sure plenty of instance space on compute nodes
  3. Install cmi-0.3.img into XOS images/ directory
  4. Install CentOS-6-cdnnode-0.3.img into XOS images/ directory
  5. Wait for these two images to be loaded into glance (check glance image-list for status)
  6. XOS UI: Add cmi and CentOS images to MyDeployment
  7. Run recipe xos/configurations/cord-pod/pod-cdn.yaml * this will create mysite_cdn slice, cdn-public network, and add management and cdn-public networks to slice
  8. Instantiate CMI instance in mysite_cdn * flavor: m1.large * image: cmi-0.3.img
  9. edit configurations/cord-pod/cdn/cmi-settings.sh * update COMPUTE_NODE and MGMT_IP to match CMI instance * update NODE_KEY to match ssh key for root @ the compute node * do not change VM_KEY; the pubkey is baked into the instance
  10. edit configurations/cord-pod/cdn/cmi.yaml
    • update gateway_ip and gateway_mac to reflect public internet gateway CMI will use
  11. copy the keygen and allkeys.template to the private/ directory
  12. copy cmi_id_rsa
  13. run setup-cmi.sh
    • this will SSH into the CMI and run setup, then modify some settings.
    • it may take a long time, 10-20 minutes or more
    • takeover script will be saved to takeovers/. Takeover script will be used in the next phase.

CDN on VTN - cdnnode

  1. Instantiate cdnnode instance in mysite_cdn * flavor: m1.cdnnode * CenOS-6-cdnnode-0.3.img
  2. Log into compute node and Attach disk * virsh attach-disk <instance_name> /dev/sdc vdc --cache none * (make sure this disk wasn't used anywhere else!)
  3. log into cdnnode VM * make sure default gateway is good (check public connectivity) * make sure arp table is good * make sure CMI is reachable from cdnnode * run takeover script that was created by the CMI * (I suggest commenting out the final reboot -f, and make sure the rest of it worked right before rebooting) * Node will take a long time to install
  4. log into cdnnode * to SSH into cdnnode, go into CMI, vserver coplc, cd /etc/planetlab, and use debug_ssh_key.rsa w/ root user * check default gateway * fix arp entry for default gateway

CDN on VTN - cmi part 2

  1. run setup-logicalinterfaces.sh

CDN on VTN - important notes

We manually edited synchronizers/vcpe/templates/dnsasq_safe_servers.j2 inside the vcpe synchronizer VM:

# temporary for ONS demo
address=/z.cdn.turner.com/207.141.192.134
address=/cnn-vh.akamaihd.net/207.141.192.134

Test Commands

Restart CDN after power-down
