Installation

Building from source

Run:

cargo build --release --features production

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

Create the database and the configuration file (see example). Default config file path is /etc/mitra/config.yaml, but it can be changed using CONFIG_PATH environment variable.

Start Mitra:

./mitra

An HTTP server will be needed to handle HTTPS requests and serve the frontend. See the example of nginx configuration file.

Building instructions for mitra-web frontend can be found at https://codeberg.org/silverpill/mitra-web#project-setup.

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