Installation

Building from source

Run:

cargo build --release --features production

This command will produce two binaries in target/release directory, mitra and mitractl.

Install PostgreSQL and create the database:

CREATE USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

Create configuration file by copying contrib/mitra_config.yaml and configure the instance. Default config file path is /etc/mitra/config.yaml, but it can be changed using CONFIG_PATH environment variable.

Put any static files into the directory specified in configuration file. Building instructions for mitra-web frontend can be found at https://codeberg.org/silverpill/mitra-web#project-setup.

Start Mitra:

./mitra

An HTTP server will be needed to handle HTTPS requests. See examples of Nginx and Caddy configuration files.

To run Mitra as a systemd service, check out the systemd unit file example.

Debian package

Download and install Mitra package:

dpkg -i mitra.deb

Install PostgreSQL and create the database:

CREATE USER mitra WITH PASSWORD 'mitra';
CREATE DATABASE mitra OWNER mitra;

Open configuration file /etc/mitra/config.yaml and configure the instance.

Start Mitra:

systemctl start mitra

An HTTP server will be needed to handle HTTPS requests. See examples of Nginx and Caddy configuration files.
