Hi we are exploring the reality of installing Memcached to work with a Windows, IIS, MSQL cluster!
We have two web nodes with a third management node that also has the moodle application for resilience.
My questions is
1. Do we need a separate server for Memcached?
2. Could we install it on the managment server?
3. Or should it be installed on each web node?
4. How does on then set up MUC?
Thanks
PS should be in Performance & Hardware forum
It should.... moving. Can't help you with Windeez though.
Well it isnt really a windy issue juts a general set of questions. So in a Linux environment could someone answer any of these questions
Cheers
You need a minimum of ONE installation of memcached that can be accessed by all the front-ends. The cached information is shared, so this is important. You can put it anywhere you like (that meets the requirement of being accessible to all front-ends).
I would say that for Moodle there is no requirement for multiple servers. It doesn't load-balance or provide failover anyway.
Thanks Howard
We do have a management server that would be accessible from both front-ends. Just not really sure whether I should put memcached on it as this server does other tasks such as cron and acting as a 3rd web node if we have problems with the cluster
I suppose if I installed Memcached on this server I would have to make both webs access it, along with having itself access its self!
This is looking less likely to be worth it and more likely that I would need a dedicated VM
Cheers
