Installation

There are multiple ways to install «Ihatemoney» on your system :

  1. With Docker

  2. Via Yunohost (a server operating system aiming to make self-hosting accessible to anyone)

  3. On a Cloud Provider

  4. Via a manual installation

Note

We lack some knowledge about packaging to make Ihatemoney installable on mainstream Linux distributions. If you want to give us a hand on the topic, please check-out the issue about debian packaging.

With Docker

Docker images are published on the Docker hub.

This is probably the simplest way to get something running. Once you have Docker installed on your system, just issue :

docker run -d -p 8000:8000 ihatemoney/ihatemoney

Ihatemoney is now available on http://localhost:8000.

All settings can be passed with -e parameters e.g. with a secure SECRET_KEY, an external mail server and an external database:

docker run -d -p 8000:8000 \
-e SECRET_KEY="supersecure" \
-e SQLALCHEMY_DATABASE_URI="mysql+pymysql://user:pass@10.42.58.250/ihm" \
-e MAIL_SERVER=smtp.gmail.com \
-e MAIL_PORT=465 \
-e MAIL_USERNAME=your-email@gmail.com \
-e MAIL_PASSWORD=your-password \
-e MAIL_USE_SSL=True \
ihatemoney/ihatemoney

If you are running this locally, you might need to disable the secure session cookies, as they do not work locally. You need to pass -e SESSION_COOKIE_SECURE=False to docker run.

A volume can also be specified to persist the default database file:

docker run -d -p 8000:8000 -v /host/path/to/database:/database ihatemoney/ihatemoney

To enable the Admin dashboard, first generate a hashed password with:

docker run -it --rm --entrypoint ihatemoney ihatemoney/ihatemoney generate_password_hash

At the prompt, enter a password to use for the admin dashboard. The command will print the hashed password string.

Add these additional environment variables to the docker run invocation:

-e ACTIVATE_ADMIN_DASHBOARD=True \
-e ADMIN_PASSWORD=<hashed_password_string> \

Additional gunicorn parameters can be passed using the docker CMD parameter. For example, use the following command to add more gunicorn workers:

docker run -d -p 8000:8000 ihatemoney/ihatemoney -w 3

On a Cloud Provider

Some Paas (Platform-as-a-Service), provide a documentation or even a quick installation process to deploy and enjoy your instance within a minute:

Via a manual installation

Requirements

«Ihatemoney» depends on:

  • Python: any version from 3.6 to 3.10 will work.

  • A database backend: choose among SQLite, PostgreSQL, MariaDB (>= 10.3.2).

  • Virtual environment (recommended): [python3-venv]{.title-ref} package under Debian/Ubuntu.

We recommend using virtual environments to isolate the installation from other softwares on your machine, but it’s not mandatory.

If wondering about the backend, SQLite is the simplest and will work fine for most small to medium setups.

Note

If curious, source config templates can be found in the project git repository.

Install

Install the latest release with pip:

pip install ihatemoney

Test it

Once installed, you can start a test server:

ihatemoney runserver

And point your browser at http://localhost:5000.

Generate your configuration

  1. Initialize the ihatemoney directories:

    mkdir /etc/ihatemoney /var/lib/ihatemoney
    
  2. Generate settings:

    ihatemoney generate-config ihatemoney.cfg > /etc/ihatemoney/ihatemoney.cfg
    chmod 740 /etc/ihatemoney/ihatemoney.cfg
    

You probably want to adjust /etc/ihatemoney/ihatemoney.cfg contents, you may do it later, see Configuration.

Configure database with MariaDB (optional)

Note

Only required if you use MariaDB. Make sure to use MariaDB 10.3.2 or newer.

  1. Install PyMySQL dependencies. On Debian or Ubuntu, that would be:

    apt install python3-dev libssl-dev
    
  2. Install PyMySQL (within your virtual environment):

    pip install 'PyMySQL>=0.9,<1.1'
    
  3. Create an empty database and a database user

  4. Configure SQLALCHEMY_DATABASE_URI accordingly

Configure database with PostgreSQL (optional)

Note

Only required if you use Postgresql.

  1. Install python driver for PostgreSQL (from within your virtual environment):

    pip install psycopg2
    
  2. Create the users and tables. On the command line, this looks like:

    sudo -u postgres psql
    postgres=# create database mydb;
    postgres=# create user myuser with encrypted password 'mypass';
    postgres=# grant all privileges on database mydb to myuser;
    
  3. Configure SQLALCHEMY_DATABASE_URI accordingly.

Configure a reverse proxy

When deploying this service in production, you want to have a reverse proxy in front of the python application.

Here are documented two stacks. You can of course use another one if you want. Don’t hesitate to contribute a small tutorial here if you want.

  1. Apache and mod_wsgi

  2. Nginx, Gunicorn and Supervisord/Systemd

With Apache and mod_wsgi

  1. Fix permissions (considering www-data is the user running apache):

    chgrp www-data /etc/ihatemoney/ihatemoney.cfg
    chown www-data /var/lib/ihatemoney
    
  2. Install Apache and mod_wsgi : libapache2-mod-wsgi(-py3) for Debian based and mod_wsgi for RedHat based distributions

  3. Create an Apache virtual host, the command ihatemoney generate-config apache-vhost.conf will output a good starting point (read and adapt it).

  4. Activate the virtual host if needed and restart Apache

With Nginx, Gunicorn and Supervisord/systemd

Install Gunicorn:

pip install gunicorn
  1. Create a dedicated unix user (here called ihatemoney), required dirs, and fix permissions:

    useradd ihatemoney
    chown ihatemoney /var/lib/ihatemoney/
    chgrp ihatemoney /etc/ihatemoney/ihatemoney.cfg
    
  2. Create gunicorn config file :

    ihatemoney generate-config gunicorn.conf.py > /etc/ihatemoney/gunicorn.conf.py
    
  3. Setup Supervisord or systemd

    • To use Supervisord, create supervisor config file :

      ihatemoney generate-config supervisord.conf > /etc/supervisor/conf.d/ihatemoney.conf
      
    • To use systemd services, create ihatemoney.service in /etc/systemd/system/ihatemoney.service 1:

      [Unit]
      Description=I hate money
      Requires=network.target postgresql.service
      After=network.target postgresql.service
      
      [Service]
      Type=simple
      User=ihatemoney
      ExecStart=%h/ihatemoney/bin/gunicorn -c /etc/ihatemoney/gunicorn.conf.py ihatemoney.wsgi:application
      SyslogIdentifier=ihatemoney
      
      [Install]
      WantedBy=multi-user.target
      

      Obviously, adapt the ExecStart path for your installation folder.

      If you use SQLite as database: remove mentions of postgresql.service in ihatemoney.service. If you use MariaDB as database: replace mentions of postgresql.service by mariadb.service in ihatemoney.service.

      Then reload systemd, enable and start ihatemoney:

      systemctl daemon-reload
      systemctl enable ihatemoney.service
      systemctl start ihatemoney.service
      
  4. Copy (and adapt) output of ihatemoney generate-config nginx.conf with your nginx vhosts2

  5. Reload nginx (and supervisord if you use it). It should be working ;)


1

/etc/systemd/system/ihatemoney.service path may change depending on your distribution.

2

typically, /etc/nginx/conf.d/ or /etc/nginx/sites-available, depending on your distribution.
