anyone have magento running in a HA/Load Balanced web farm?.
I'm using HAProxy with 5 web servers in my test system.. I have Prestashop running on these servers also, and have no issue with the LB using different servers, but with magento it only works on the original node and fails on the other nodes with server error 500.
The Database is hosted on its own DB server, magento installed/cloned to all web farm members
I know the LB is working fine as I have other apps running on it and along with Prestashop that is running on multiple nodes. I have sample of my setup... identical to below except just the 1 DB Server and 5 app nodes.
Not sure why magento won't accept this config, any insight appreciated.
Can you tell more about your stack, are you using Apache or Nginx? mod_php or PHP-fpm?
Since you're getting error 500, can you grep full error from your log files? It should show us the main cause.
If you're using Nginx with PHP-FPM, it could be that your nginx configuration file is not okay. Magento2 has recommended NGINX configuration which can be good starting point.
