Cerb6 Software License

Dual license?

Version numbers

Cerb6's version numbers are in the format: <generation>.<release>.<update>

  • Application generations represent software evolution and innovation in the purest form. A new generation embodies everything learned from earlier work without the requirement to be conceptually or technologically compatible with the past. Generations in our project typically occur once every 2-3 years.
  • Major releases represent significant improvements in functionality, usability, or style. Releases are focused on delivering new value, and they are required to be consistent with the current generation's concepts and technology. Major releases occur every 2-3 months.
  • Maintenance updates implement usability feedback and fix reported bugs. Maintenance updates occur every 1-3 weeks.

Therefore, a version of 5.4.2 means:

  • 5th generation (5.x)
  • 4th major release (5.4.x)
  • 2nd maintenance update (5.4.2)

The next maintenance update is: 5.4.3

The next major release is: 5.5.0

The next generation is: 6.0.0

Clustering

Two web server nodes; one database node

  • Install Cerb completely on one web node first (or outside of the cluster and move the database in)

  • Grant DB access to the other nodes

  • Run the installer requirements checker on the other nodes

  • Copy the framework.config.php to the other nodes

  • Load balancer share sessions (cookies)

  • Memcached (share cache) -- edit /etc/memcached.conf and make sure bind to internal IP -- enable + copy MEMCACHED node list to all framework.config.php -- make sure php5-memcache package (ext) is installed

Replicate /storage filesystem


-  NFS:
-  Firewall ports (``rpcinfo -p``: portmapper, nfs, nlockmgr, lockd)
-  Move ``storage`` on slaves
-  ``mount -o"rw,hard,intr,async,nosuid,nodev" host:/path/to/master/storage storage``
