Barracuda

Aegir master install in /var/aegir

Not as tuned and featured as the Octopus Aegir install. Best practice is to use Octopus for production.

• Barracuda
  • README
  • Updates
  • CHANGELOG
• g.d.o: BOA

• How to disable all caching and aggregation? - Using dev. in in site alias disabled hardcoded performance. Also for PHP errors and logging.

• Are there any specific good habits to learn?
• The best recipes for disaster

• Are bug fixes/patches applied to the current BOA stable release?

Octopus

• Octopus installs alongside Barracuda, providing an Aegir satellite instance bundled with various distro install profiles and performance modules.

/data/disk/o1/
  install root
/data/disk/o1/distro/001/
  preinstalled platforms
/data/disk/o1/static/
  created platforms

• Barracuda vs Octopus and site development best practice, I'm still confused.
• Extra modules available in all platforms

Setup

• Barracuda: INSTALL.txt
• Octopus: INSTALL.txt

• Ubuntu Server
  • older script; boxbootstrap.sh

Use _FORCE_GIT_MIRROR=github because it is 10x faster than others. Automatic these days.

Make sure that all sites have its associated Client, otherwise the site will be listed as available for all Clients/Users you have added.

• BOND.sh - tuning script

• http://drupalcode.org/project/barracuda.git/blob/HEAD:/docs/REMOTE.txt

Maintenance

xdrago cron runs tool helper scripts

• usage.sh

Upgrade

Do not use apt to upgrade. Upgrading got easier with BOA 2. See UPGRADE.txt for full details.

# Download and run BOA Meta Installer.
wget -q -U iCab http://files.aegir.cc/BOA.sh.txt
bash BOA.sh.txt

Will honour settings in;
/root/.barracuda.cnf
/root/.o1.octopus.cnf
/root/.o2.octopus.cnf

this is now old?!:

# To upgrade system and Aegir Master Instance to Stable
barracuda up-stable

# To upgrade system and Aegir Master Instance to HEAD
barracuda up-head

# To upgrade selected Aegir Satellite Instance to Stable
octopus up-stable o1

# To upgrade *all* Aegir Satellite Instances to Stable
octopus up-stable all

# To upgrade selected Aegir Satellite Instance to HEAD
octopus up-head o1

# To upgrade *all* Aegir Satellite Instances to HEAD
octopus up-head all

Certain configs can be heldback on upgrade. Upgrading CFS config can lose ports.

Caching

• Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

New system uses only Redis cache and the same configuration for all Drupal 6 and Drupal 7 platforms. This new system doesn't require any extra module to be enabled in any site. Complete integration is already enabled by default for every platform/site installed by default and for every custom platform as before - the next day after first site on the custom platform has been created. You can disable this caching layer using the same modules/cache/NO.txt control file as before. While there is just one cache engine (Redis) used, there is also an automatic, instant failover to standard database caching, just in case Redis is not available for some reason. You can also disable Redis cache on the fly for debugging by adding ?noredis=1 to any URL.

Development

Alias a dev.* site domain to bypass JS compression and CSS aggregation.

Management

To manage a web site project, create a pointer build file which will point towards a bespoke profile.

Add a builds/ directory to the Aegir instance root and git clone distro build files to (and from for backup, etc.) there.

Create platform and then site using the build file path.

Needs development; check where profile inheretance to make splitting out dev/ui modules for production sites.

To check; use Drush make generate to refresh make?
