SysAdmins

We can always use SysAdmin support to help out with our infrastructure: developing tools & maintaining sites.

Setting up a New Instance

Eden project have 2 servers kindly donated by ​Zen Internet.
These run KVM to provide different virtual machines.
We use ​Proxmox to manage these VMs

These documents are secured - ask for access if you are going to contribute:

• ​IP Addresses/RAM Allocations for Eden Infrastructure
• ​Setting up a new VM instance on Eden Infrastructure

Upgrading an Instance

Need to decide whether the site will be upgraded straight from Trunk, or whether upgrades are staged via a Test server.

We manage upgrades using Fabfile.

1. Add the site to fabile.py
2. If no keys generated yet, then generate some:

   fab generate_keys
   

3. deploy keys

   fab <site> distribute_keys
   

4. Run the upgrade (as/when required)

   fab <site> deploy

ToDo

Infrastructure Virtual Machine Template

• Update shell aliases: compile/pull
  • convert to scripts in /usr/local/bin (as per ISO/VM)
• Add maintenance site & HTML
• Rename site as xxxx.sahanafoundation.org
  • To work with fabfile
• Provide a script to manage the MySQL root pw change
  • change the password
  • edit Eden's 000_config.py
  • edit /root/.my.cnf
• Update Eden
• Update Web2Py (as-required)
• Update OS (to Squeeze & then maintain patches)
• Increase swap to 2048Mb (from 750Mb)
  • can we do this in image? Add an emergency swapfile?
  • Add extra disk for those instances which need extra capacity

Test

• Set up an instance of Hudson to automatically run through our Selenium tests

Demo

• Have a set of reference data available

Pootle

• Upgrade to 2.1.4 (from 2.1.1)

Trac

• Upgrade to 0.12.1
  • Check Plugin Dependencies
• Convert from sqlite to PostgreSQL (or MySQL) to improve performance
• Add Timing & Estmation Plugin
• Investigate a fix or alternative to ​http://trac-hacks.org/wiki/MathCaptchaPlugin for allowing Trac users to register bugs anonymously whilst not locking out our testing team.
• See if we can not send emails out to users for the updates they make themselves (maybe fixed in 0.12.x?)
• Investigate a fix for the last section edit doubling-up the footers (maybe fixed in 0.12.x?)

Release Process

• DeveloperGuidelinesReleaseProcess
• Bzr start-commit hook to check for existence of 'compiled' folder

Translation Process

• Bzr start-commit hook to update all languages (need a script rather than the current appadmin UI method)

  cd web2py
  python web2py.py -S eden -R applications/eden/static/scripts/tools/languages.py
  

• Scripts to automate the conversion 2 PO & upload/download to/from Pootle: UserGuidelinesLocalisation
