Setup

Please note:

🚨 The software is not production-ready. There may be bugs and WILL be breaking changes. If you insist on running your own instance, always ensure you have up-to-date configs and run gulp migrate && gulp && pm2 reload all after pulling. 🚨

• these instructions are not step-by-step or complete
• you should be able to read, be comfortable with a command line and have problem solving skills

Requirements

• Linux (debian used in this example)
• Node.js (to run the app)
• MongoDB (database, duh)
• Redis (sessions, build task queue, locks, caching, websocket data)
• Nginx (handle https, serve static content, GeoIP lookup)
• Certbot/letsencrypt (for https cert)
• Graphicsmagick+Imagemagick (thumbnailing images, generating captchas)
• Ffmpeg (thumbnailing videos)

1. Setup server with some basics

• new user to run the nodejs backend
• ssh root login disabled, key login only, etc
• iptables only open http, https and ssh ports on INPUT

2. Install dependencies. You may need to add sources depending on your distro.

$ sudo apt-get update
$ sudo apt-get install nginx ffmpeg imagemagick graphicsmagick

3. Install MongoDB and configure authentication

4. Install and configure Redis

5. Install nodejs Recommended to use node version manager (nvm). Install nvm then run the following commands to get the LTS version of nodejs.

$ nvm install --lts
$ nvm use --lts

You can also repeat this process in future to update node versions as they are generally backwards compatible.

6. Configure nginx

• Use the example config included in configs/nginx.example and put it in /etc/nginx/sites-available/YOURDOMAIN.COM, then symlink it to /etc/nginx/sites-enabled/YOURDOMAIN.com.
• Make sure the sites enabled folder is included by /etc/nginx/nginx.conf
• Get https certificate from letsencrypt.
• For geo flags, follow this guide to setup the legacy GeoIP db and add these directives to the http block in /etc/nginx/nginx.conf:

geoip_country /usr/share/GeoIP/GeoIP.dat;
geoip_city /usr/share/GeoIP/GeoIPCity.dat;

7. Clone this repo, browse to the folder and set some things up

# copy example config file and edit it
$ cp configs/main.js.example configs/main.js && editor configs/main.js

# copy example custompages for rules and faq and edit
$ cp views/custompages/faq.pug.example views/custompages/faq.pug
$ cp views/custompages/rules.pug.example views/custompages/rules.pug

# install dependencies and run build tasks
$ npm install
$ npm run-script setup

# setup the database and folder structure, creates admin account admin:changeme
# dont run this again unless you want to completely irreversibly wipe everything
$ gulp reset

Use https://realfavicongenerator.net/ to generate favicons how you want them to look and replace the files in gulp/res/icons/ with the icons from that package

# start all the backend processes
$ npm run-script start
$ gulp

# some commands you may need to use in future/find helpful

# pm2 is a process manager for nodejs
$ pm2 list #list running pm2 processes
$ pm2 logs #see logs
$ pm2 reload all #reload all backend processes

# gulp is used for various jobs like minifying and compiling scripts
$ gulp --tasks #list available gulp tasks
$ gulp migrate #check for and run db migrations
$ gulp #run default gulp task

8. Optionally, if you plan to use the webring and want to make requests with tor to mask your origin server IP: Install docker and run torproxy in a container: https://github.com/dperson/torproxy Edit configs/webring.json and wer proxy enabled:true
