Install and Run Rocket.Chat on OpenSUSE Leap 42.2

Last updated 2017-08-26

These are barebones instructions for how to set up a Rocket.Chat server on OpenSUSE Leap 42.2 using nginx as a reverse proxy. These will help you set up a system you can experiment with. THEY ARE NOT INTENDED FOR SETUP OF A PRODUCTION SYSTEM! They are oriented on using a VM from AWS, but should work for any Leap 42.2 system.

Overview

You will install and configure:

Debugging Travis CI locally using Docker

This assumes you've got docker-machine installed, running, and can do docker run

1. Get a debug instance running

    docker run --name travis-debug -dit quay.io/travisci/travis-ruby /sbin/init
    docker exec -it travis-debug bash -l

Huge thanks to @bounga for his post that didn't assume you've got a working /etc/nginx.conf. Everyone else's posts just assume that you've got the same /etc/nginx.conf as they do, and when you don't, you're screwed.

I like the sites-available/sites-enabled paradigm so I did this:

mkdir /etc/nginx/sites-available /etc/nginx/sites-enabled
ln -s /etc/nginx/sites-enabled /etc/nginx/vhosts.d

I highly recommend using capistrano-puma. Super basic steps condensed from the capistrano-puma readme:

1. Add this to your Gemfile in the development group:

Installing nokogiri manually on OpenSUSE Leap 42.1:

gem install nokogiri -- --use-system-libraries \
    --with-xml2-dir=/usr \
    --with-xslt-dir=/usr \
    --with-exslt-dir=/usr

I can't say I understand why I had to specify those dirs as that's the system default, but it works and I'm in a hurry. I'll update this as I learn more someday.

Meanwhile, you may be interested in the Nokogiri issue that this stems from
