Good day @arnav13081994,
Yes, you've.
"client_body_buffer_size 10K;"
This directive sets the buffer size for storing the client request body. In this case, it is set to 10 kilobytes (10k). It determines the maximum amount of data that Nginx can temporarily store from the client while the request is being processed.
Since the client_max_body_size directive is set to 16 megabytes (miga), you should choose a client_body_buffer_size value that accommodates this maximum size.
Considering that Nginx uses memory for other purposes as well, you can allocate a buffer size slightly larger than the expected maximum request body size.
Folks;
I haven’t been updating this for a while, and this file should be considered a starting point, not the end-all-be-all.
Every production setup and server is different; you’ll need to benchmark your performance, tweak things on the go, and read the official docs.
Nowadays, I’m dealing with pure NGINX less and cloud load balancers more;
however, if I see anything worthwhile to add here or any change that can improve in a system-agnostic way, I’ll update the file.
One other remark: This file's particular use was for a very high-throughput system with relatively smaller payloads. If you have larger payloads, your memory utilization will increase, and having too high of a file limit can indeed crash the process due to memory pressure.
So, yep, lots of moving parts, yet I tried to document the file as best as I can.
Cheers.
Hi, checking up, i run a pterodactyl.io hosting company (MCST.IO), and ive ran into some issues regarding gzip for plugin module's for minecraft, im unsure if the issue is gzip or php-fpm, but in general should gzip just be disabled from nginx.conf ? unsure as default conf does not match my other node server configs at default.
Hi @v0lkan,
Unlike for the
access_log
directive,error_log off;
does not disable the error logs.error_log off;
would create a file named "off" for logging the errors within the default NGINX config files directory.This is also mentioned in the NGINX blog post, in which it recommends specifying
error_log /dev/null emerg;
in cases where "disabling" error logging is preferred :)Thanks! :)
