NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Generation of a Self Signed Certificate

Generation of a self-signed SSL certificate involves a simple 3-step procedure:

STEP 1: Create the server private key

openssl genrsa -out cert.key 2048

STEP 2: Create the certificate signing request (CSR)

openssl req -new -key cert.key -out cert.csr

# Chanage directories to /tmp
cd /tmp
# Download the Generic Cloud image from the distro downloads
wget https://Link_to_Generic_Cloud_image.com
# Validate the file is a QEMU QCOW2 image.
file ./Generic_Cloud_Image.qcow2


# Set this to your Proxmox host name; it's case sensitive! Check with `pvesh ls /nodes`

GeoIP Block NGINX Ubuntu 20.04

Block or filter IPs based on location in Nginx (tested on 1.18.0) on Ubuntu 20.04.

Install Nginx modules

To make use of the geographical filtering, we must first install the Nginx GeoIP module as well as the GeoIP database containing the mappings between visitors’ IP addresses and their respective countries. To do so, let’s execute:

$ sudo apt install libnginx-mod-http-geoip geoip-database

IP Tables (iptables) Cheat Sheet

IPTables is the Firewall service that is available in a lot of different Linux Distributions. While modifiying it might seem daunting at first, this Cheat Sheet should be able to show you just how easy it is to use and how quickly you can be on your way mucking around with your firewall.

Resources

The following list is a great set of documentation for iptables. I used them to compile this documentation.
