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.

Multiple MySQL Versions for Development

Options included below:

• Using Docker docker-compose
• Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

# This patch is required:
# For: google authentication.
# When: Running rails on a port other than 80 where a proxy server proxies to rails.
# Cause: 1. Rack is not able to figure out that it should not set the realm url port to the rails custom port in case the full_host is mentioned using
#           OmniAuth.config.full_host
#        2. OpenID tries to validate the incoming callback url with the custom port that rails is running on and throws the error "return_to #{meth.to_s} does not match".
