Server set up

The server requires:

• NodeJS 8.x
• inbound Internet access
• OpenResty
• redis
• lua rocks

This has been tested on ubuntu 16.04, but should work on any modern Linux distro. It used the Linux users for its user management, so this will ONLY work on Linux, no macOS, BSD or Windows.

The steps below are for a new ubuntu server, they should be mostly the same for other distros, but the paths and availability of packages may vary. A dedicated server is highly recommended (since it will make ever user a system user), a VPS like Digital Ocean will do just fine.

• Install openresty

  OpenResty® Linux Packages

• These packages are needed for the PAM node package

  apt install libpam0g-dev build-essential

• Install redis

  apt install redis-server

• install lua plugin

apt install luarocks
sudo luarocks install lua-resty-auto-ssl

• openresty config
