Signal Server Installation Guide

Author: Aqnouch Mohammed [email protected]

Abstract

This paper is a quickstart for anyone aims to setup a working Signal Server.

What Is Signal

Signal is an encrypted instant messaging and voice calling application for Android. It uses the Internet to send one-to-one and group messages, which can include images and video messages, and make one-to-one voice calls. Signal uses standard phone numbers as identifiers and end-to-end encryption to secure all communications to other Signal users.

Installation Steps

The main server source code could be found here:

https://github.com/signalapp/Signal-Server

Before starting working let's clonned the source code:

https://github.com/signalapp/Signal-Server.git

Inter the project folder:

cd Signal-server

Build the main server server jar

mvn install -DskipTests

Prerequisites

To be sure to have the latest version of the programmes.

sudo apt-get update

Install Java

sudo add-apt-repository -y ppa:webupd8team/java
sudo apt-get update 
sudo apt-get install -y oracle-java8-installer
sudo apt-get install -y oracle-java8-unlimited-jce-policy

Install Redis

sudo apt-get install -y redis-server

Install database

sudo apt-get install postgresql postgresql-contrib -y

Create postgres root user:

sudo -i -u postgres
createdb accountdb
createdb messagedb 

createuser --interactive
psql
ALTER USER "Signal" WITH PASSWORD 'Signal!!';

##Remotely access to the postgresql database To open the port 5432 edit your /etc/postgresql/9.*/main/postgresql.conf and change

listen_addresses='localhost'

listen_addresses='*'

Edit

/etc/postgresql/9.*/main/pg_hba.conf

And add

host all all * md5

And restart or restart you DBMS

invoke-rc.d postgresql restart

The configuration files

Here a working server file filled with fake values. You have to provide your own values:

twilio: # Twilio gateway configuration
  accountId: AC0a435e5bc49AC0a435e5bc49AC0a435v
  accountToken: bdc211b8a91990988166a82a65f0aafv

      port: 8080
  adminConnectors:

Database migration

Once you have PostresSQL Up&Running with username, password, messagesdb and accountsdb (two db can be the same one) and these parameters are well coded inside TSS' yml file as seen above as jdbc string , you can now create data structures needed by the application.

java -jar ../jars/Signal-2.1.jar  messagedb migrate  ../config/Signal.yml
java -jar ../jars/Signal-2.1.jar  accountdb migrate  ../config/Signal.yml

S3 configuration

create S3 bucket an IAM user, and add it to the S3FullAccess group

Reverse proxy

sudo a2enmod proxy proxy_http proxy_wstunnel

The configuration to add the the site availible section in: apache /etc/apache2/sites-available/

ServerAdmin [email protected] ServerName kalam.app

    DocumentRoot /var/www/kalam/

    <Directory /var/www/tkalam>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>	

SSLCertificateFile /etc/letsencrypt/live/kalam.app/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/kalam.app/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf

Turn server installation

sudo apt-get install -y coturn
sudo apt-get install -y build-essential
sudo turnserver -a -o -v -n  --no-dtls --no-tls -u test:test -r "someRealm"

SSL Certificate

Create the ssl certificate

sudo add-apt-repository ppa:certbot/certbot -y
sudo apt-get update -y
sudo apt-get install python-certbot-apache  -y
sudo certbot --authenticator standalone --installer apache -d <yourdomain> --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2"
