Optimum config for NodeBB under NGINX

[phenomlab]

I noticed that my v3 instance of NodeBB in test was so much slower than live, but was using the same database etc. On closer inspection, the nginx configuration needed a tweak, so I’m posting my settings here so others can benefit from it. Note, that various aspects have been redacted for obvious privacy and security reasons, and to this end, you will need to substitute these values for those that exist in your own environment.

server {
    # Ensure you put your server name here, such as example.com www.example.com etc.
	server_name sservername;
	listen x.x.x.x:443 ssl http2;
	access_log /path/to/access.log;
	error_log /path/to/error.log;

	ssl_certificate /path/to/ssl.combined;
	ssl_certificate_key /path/to/ssl.key;
    # You may not need the below values, so feel free to remove these if not required

I’ve added comments at the obvious places where you need to make changes. Depending on how your server is configured, and it’s capabilities, this should improve performance no end.

There is a caveat though, and it’s an important one

Don’t use insane levels in the below section

	client_body_buffer_size 10K;
	client_header_buffer_size 1k;
	client_max_body_size 8m;
	large_client_header_buffers 4 4k;

	client_body_timeout 12;
	client_header_timeout 12;
	keepalive_timeout 15;
	send_timeout 10;

Keep to these values, and if anything, adjust them DOWN to suit your server.

Further configuration changes can be made to the nginx core itself, although my recommendation here is to leave this alone unless you are sure you know what you are doing.

hi @phenomlab , is there any reason that you do not use 4567?

Additionally, do you scale your forum up to 3 ports?

@crazycells hi - no security reason, or anything specific in this case. However, the nginx.conf I posted was from my Dev environment which uses this port as a way of not interfering with production.

And yes, I use clustering on this site with three instances.
