How to configure NGINX as a load balancer

NGINX is primarily used as a web server, a reverse proxy, and/or a load balancer.

In this short video, we'll go over how you can take an existing NGINX reverse proxy setup and convert it to load balance traffic to multiple backend servers.

NGINX does a great job of load balancing traffic, but that doesn't mean it needs to be complicated to configure and by the end of this video you should see that it isn't complicated at all.

Presented by one of our Training Architects, Keith Thompson.

Great video. But can I put the same config on multiple machines ?? If this is running on one machine and that machine goes down, do I lose the routing ? ... even if all the other machines are up and running ?

Hello I have HostGator with a dedicated server. Wanted to add a couple more dedicated servers and was wondering if this would load balance them for me.

Hi, how would I do with the location /static { } section if the apps weren't in the localhost but in different servers?
Thank you.

hey, thanks for the tutorial.
I have a site running with nginx & php fpm & sqlite3 for database. if I just copy the site's content from one server to another, then the data isn't gonna sync automatically.

TLDR: how can i make this work with dynamic sites?
anyone knows a solution?

Will this interfere with my current NGINX HTTPS reverse proxy setup and SSL certificates?

[prmswrn]

Thank you. I am trying to configure load balancer for two different docker containers. Is it possible through nginx?

[Hellmiauz]

So the server that has the application is also the load balancer. You don't need an extra load balancer.
