livechan

livechan is a live IRC like image board written in node.js.

Installation

Requirements:

git
node.js
NPM
MongoDB
ImageMagick
cairo and other canvas dependencies (needed for the captcha module)
FFmpeg (if audio/video support desired)

Suggested OS is ubuntu 14.04

The commands below are based on a Debian installation, other distros / operating systems will vary.

Install git:

sudo apt-get install git
Install node.js and NPM:

sudo apt-get install nodejs npm nodejs-legacy

(nodejs-legacy creates a symlink from /usr/bin/node to Debian's location /usr/bin/nodejs, needed for installation scripts that call "node".)

Install MongoDB:

sudo apt-get install mongodb
Install ImageMagick:

sudo apt-get install imagemagick
Install the dependencies of the canvas module:

sudo apt-get install libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++
Install FFmpeg. See instructions at https://ffmpeg.org/download.html.

Add the sources from http://www.deb-multimedia.org/ to your /etc/apt/sources.list and do:

sudo apt-get update
sudo apt-get install deb-multimedia-keyring
sudo apt-get update
sudo apt-get install ffmpeg

Alternately you can download a static build from http://ffmpeg.gusari.org/static/ and copy the extracted binaries to /usr/local/bin:

sudo cp ffmpeg ffprobe /usr/local/bin

Note that many distributions come with Libav in place of FFmpeg. FFmpeg is recommended. Using Libav instead should be possible, but will require appropriate changes to format-image.js and generate-thumbnail.js in lib/utils.

If you do not want audio/video support, you should edit your config.js so that video_formats and audio_formats are both empty arrays.

Clone the git repo

git clone https://github.com/emgram769/livechan-js.git

8.a) Install the dependencies with npm install

cd livechan-js; npm install

8.b) Download a country lookup database

wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz; gunzip GeoLiteCity.dat.gz

Restore the changes to the captcha module which were overwritten by npm install:

git checkout node_modules/captcha/captcha.js
Get ircd.js modified for livechan

cd ..; git clone https://github.com/emgram769/ircd.js; cd ircd.js; npm install; cd ../livechan-js
Make sure the public/tmp/uploads and public/tmp/thumb folders are writable

chmod 777 public/tmp/uploads public/tmp/thumb
