Taiga is a free and open-source project management system for agile developers & designers and project managers who want a beautiful tool that makes work truly enjoyable. Taiga is a very powerful, easy to use and entirely customizable application that can handle both simple and complex projects for startups, software developers. Taiga backend is written in Python and Django that provides an API. The frontend is written in JavaScript using CoffeeScript and AngularJS frameworks.
In this tutorial, we will learn how to install Taiga project management system on an Alibaba Cloud Elastic Compute Service (ECS) instance with Ubuntu 16.04.
First, log in to your https://ecs.console.aliyun.com">Alibaba Cloud ECS Console. Create a new ECS instance, choosing Ubuntu 16.04 as the operating system with at least 2GB RAM. Connect to your ECS instance and log in as the root user.
Once you are logged into your Ubuntu 16.04 instance, run the following command to update your base system with the latest available packages.
apt-get update -yBefore starting, you will need to install some dependencies required to compile python modules. You can install all of them using the following command:
apt-get install build-essential binutils-doc autoconf flex bison libjpeg-dev libfreetype6-dev zlib1g-dev libzmq3-dev libgdbm-dev libncurses5-dev automake libtool libffi-dev curl git tmux gettext -yTaiga runs on the web server. So you will need to install Nginx web server to your system. You can install it using the following command:
apt-get install nginx -yOnce Nginx is installed, start Nginx service and enable it to start on boot using the following command:
systemctl start nginx
systemctl enable nginxNodejs is also required by Taiga-events. You can install the Nodejs using the following command:
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt-get install nodejs pwgen npm -yTaiga backend is written in Python and Django Framework that uses Python 3.5. So you will need to install Python 3.5 to your system. You can install it using the following command:
apt-get install python3 python3-pip python-dev python3-dev python-pip virtualenvwrapper libxml2-dev libxslt-dev -yNext, you will need to install circus for managing the Taiga-events process created with CoffeeScript. You can install it using the following command:
apt-get install circus -yOnce circus is installed, start circusd service and enable it to start on boot using the following command:
systemctl start circusd
systemctl enable circusdTaiga uses PostgreSQL to store its database. By default, PostgreSQL is not available in Ubuntu 16.04 default repository. So you will need to add the PostgreSQL repository into the system. You can do this using the following command:
echo "deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main" | tee /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -Next, update the repository and install PostgreSQL using the following command:
apt-get update -y
apt-get install postgresql -yNext, start PostgreSQL service and enable it to start on boot using the following command:
systemctl start postgresql
systemctl enable postgresqlNext, log in to PostgreSQL user and create a database and user for Taiga:
su - postgres
createuser taiga
psql
ALTER USER taiga WITH ENCRYPTED password 'password';
CREATE DATABASE taiga OWNER taiga;Exit from the PostgreSQL shell:
qTaiga uses RabbitMQ to process the message queue. So you will need to install RabbitMQ to your server.
First, install Erlang libraries with the following command:
apt-get install erlang -yNext, add the RabbitMQ repository and Import the RabbitMQ GPG signing key using the following command:
echo 'deb http://www.rabbitmq.com/debian/ stable main' | tee /etc/apt/sources.list.d/rabbitmq.list
wget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc | apt-key add -Next, update the repository and install RabbitMQ using the following command:
apt-get update -y
apt-get install rabbitmq-server -yNext, start RabbitMQ service and enable it to start on boot using the following command:
systemctl start rabbitmq-server
systemctl enable rabbitmq-serverNext, you will need to create a new user and virtual host named "taiga" for RabbitMQ:
rabbitmqctl add_user taiga password
rabbitmqctl add_vhost taiga
rabbitmqctl set_permissions -p taiga taiga "." "." ".*"Taiga-back is a backend of Taiga written in Python and Django Web Framework that provides an API.
First, create a new Taiga user and set the password with the following command:
adduser taigaNext, log in to taiga user and create a new directory to store the log files.
su - taiga
mkdir -p ~/logsNext, clone the Taiga backend repository from GitHub and check out the latest stable branch.
git clone https://github.com/taigaio/taiga-back.git taiga-backYou should see the following output:
Cloning into 'taiga-back'...
remote: Counting objects: 32790, done.

cd taiga-back
checkout stableOutput:
Branch stable set up to track remote branch stable from origin.
Switched to a new branch 'stable'Next, create new python environment taiga using the virtualenv.
mkvirtualenv -p /usr/bin/python3 taiga
Next, log in to the new taiga virtual environment and install all python modules using the following command:
workon taiga
pip3 install --upgrade setuptools
pip3 install -r requirements.txtOnce all the required modules are installed, populate the database with necessary initial data using the following command:
python3 manage.py migrate --noinput
python3 manage.py loaddata initial_user
python3 manage.py loaddata initial_project_templates
python3 manage.py compilemessages
python3 manage.py collectstatic --noinputThe above command will create an administrator account 'admin' with password '123123'.
Next, you will need to create the configuration file for the Taiga backend. First, generate a random string of 64 characters with the following command:
pwgen -s -1 64You should see the following output:
DYnT63VmANLGw8YN0IJcRXjz7DPWoXTArpaPDojFeSDcWTooVaD4Bmx9Ej8bviczNext, create a new configuration file for the Taiga Backend:
nano ~/taiga-back/settings/local.pyAdd the following lines:
from .common import *
MEDIA_URL = "https://example.com/media/"
STATIC_URL = "https://example.com/static/"
SITES["front"]["scheme"] = "http"
SITES["front"]["domain"] = "example.com"
SECRET_KEY = "DYnT63VmANLGw8YN0IJcRXjz7DPWoXTArpaPDojFeSDcWTooVaD4Bmx9Ej8bvicz"
DEBUG = False
PUBLIC_REGISTER_ENABLED = True
DEFAULT_FROM_EMAIL = "mail@example.com"
SERVER_EMAIL = DEFAULT_FROM_EMAIL
EVENTS_PUSH_BACKEND = "taiga.events.backends.rabbitmq.EventsPushBackend"
EVENTS_PUSH_BACKEND_OPTIONS = {"url": "amqp://taiga:password@localhost:5672/taiga"}Save and close the file, then test 'taiga-back' with the following command:
workon taiga
python manage.py runserverYou should see the following output:

}
}Save and close the file when you are finished.
Circus is a process manager for Python applications that can be used for controlling and managing 'taiga-back' and 'taiga-events' process.
First, create a new Circus configuration file for running the Taiga backend.
nano /etc/circus/conf.d/taiga.iniAdd the following lines:
[watcher:taiga]
working_dir = /home/taiga/taiga-back
cmd = gunicorn
args = -w 3 -t 60 --pythonpath=. -b 127.0.0.1:8001 taiga.wsgi
uid = taiga
numprocesses = 1
autostart = true
send_hup = true
stdout_stream.class = FileStream
stdout_stream.filename = /home/taiga/logs/gunicorn.stdout.log
stdout_stream.max_bytes = 10485760
stdout_stream.backup_count = 4
stderr_stream.class = FileStream
stderr_stream.filename = /home/taiga/logs/gunicorn.stderr.log
stderr_stream.max_bytes = 10485760
stderr_stream.backup_count = 4
[env:taiga]
PATH = /home/taiga/.virtualenvs/taiga/bin:$PATH

stderr_stream.filename = /home/taiga/logs/taigaevents.stderr.log
stderr_stream.max_bytes = 10485760
stderr_stream.backup_count = 12Save the file, when you are finished.
Next, create a new logs directory for both 'taiga-events' and 'taiga-back' processes, then restart circusd service using the following command:
su - taiga
mkdir -p ~/logs
exit
systemctl restart circusdYou can now check the status of circusd using the following command:
circusctl statusYou should see the following output:
circusd-stats: active
plugin:flapping: active
taiga: active
taiga-events: activeNext, create a new Nginx virtual host directive for Taiga.
nano /etc/nginx/sites-available/taigaAdd the following lines:
server {
listen 80 default_server;
server_name _;
large_client_header_buffers 4 32k;
