Unable to start nginx after install in AWS EC2


I am very new to Kaltura. Installed Kaltura CE 13.14.0 in AWS Instance. Not been able to start nginx

– Unit kaltura-nginx.service has begun starting up.

Checked System memory and it looks fine.

Sorry but that’s not enough RAM to run a Kaltura Server instance, not even a very small/low traffic one… Please increase your RAM to at least 2G.


Ok- will try that. Thanks again
