Moodle in English -> General help -> Moodle Issues -> Re: Moodle Issues

Adam,

I have reinstalled Moodle via the softaculous installer on Cpanel. So far so good. ---> This is where you did the biggest mistake, installing moodle from a script installer. 
mentioned many times, even in moodle documentation, script installers like softaculous, fantastico, mojo market place tend to modify the code a little to suit the underlying servers so it can install fine, it as well bypasses the requirements that moodle require to work properly, in order to get it installed on hosting servers, at first moodle seems to work perfect, but it does start showing up issues as you start installing plug-ins (specially themes).

Do manual clean install!

Ken, is it that you are asking for a full ground zero and up training? (starting from a bare metal, setting up SMTP, Web Server, DB's, Tuning and administering moodle) or just moodle administration? 

You'll find matching (dont know if they match your criteria) courses on Moodle Administration, you can look into their contents and see if they really are up to the requirements. 

You can find courses HERE and HERE

Craig, my only concern is, 3 Db servers, as you said if PAN link goes down, moodle still be able to operate, where moodle relies on DB and that isnt replicated on every site, how would you expect a disconnected site to communicate with a DB server? unless few "grouped" sites have one DB node that isn't relying on PAN but LAN.

regarding moodle requiring a different prefix for each site, Have you thought of setting up shared configuration? will make administration much easier. make changes in site configuration on main, and it will be reflected all across nodes. Shared configuration is different to shared content. 

regarding DFS-R, keep management console on main server. I can understand the hub-spoke topology for moodle folder as nothing really changes there apart from when upgrading moodle or adding plug-ins, but moodledata folder will have to be on full mesh (assuming people have ability to add courses at any node - or is it the other way around, courses being added from main admin only?)

Things are still little mixed up in my mind, as I am trying to paint the picture of how I would have done it, as I had once thought about testing the whole scenario (as moodle is different than many web applications), but due to hardware limitations (still on 10 year old CPU wink) I couldn't test it myself to able to confidently point you in right direction.
 I have absolutely no knowledge of SQL Server replication to even think about that, as even thinking of a multi server setup, even Open University is using a Postgre SQL server with Master-Slave configuration not even replication. That's why I mentioned my concern regarding 3 DB nodes, but anyway, you're getting there for sure, but do keep updating as I might have something to add to IIS farming, if not, I'll have something to learn smile
