Setup & Tune (pg)Moodle

Setting up and tuning postgresql. Browsed docs and blogs. Found a tutorial on how to setup a pg database cluster. Clustering in postgres is done with the pgcluster package. pgCluster is a Synchronous Multi-Master Replication. Slony is an asynchronous master slave replicator. Asynchronous replicates can be good for heavy read, light write applications. Asynchronous replication can also be a strategy for backups: replicate master to slave, then slave can be shutdown to do backups.

checked some scripts and noted that I need to update awk, sed and grep a bit. Maybe buy a book or so.

Here some interesting tutorials:

• http://www.bolthole.com/
• TLDP: awk guide
• {en:List_of_Unix_programs}

Books:

• Classic Shell Scripting
• Sed and Awk
• Sed and Awk pocket reference
• Regular Expressions
• RegExp pocket reference

The problem wih setting up a distributed Moodle system is that the config.php file is included in the codebase. Therefore, now we still need one directory per moodle. The ideal situation would be where we just have one codebase and all userinfo in the database. The problem then is the db cnx. Try to find a problem for that.
