I am using AWS EC2 and I luched a bitnami wordpress. Now I am running my site. but I want to have another 2 sites in the same instance. How Can i do that?
Take a look here.Most probably you'll need to substitute the Wordpress stack with a LAMP stack.
Best of luck!
@bulgaru's approach is plenty functional and working. We use to recommend in situations like yours to use WP Mulsite, as you can see here: https://docs.bitnami.com/aws/apps/wordpress/#how-to-enable-multi-site-support
