Installing Ferron from pre-built binaries

The easiest way to install Ferron is installing it from pre-built binaries.

Below are the different ways to install Ferron:

Configuration examples

Basic static file serving

// Example configuration with static file serving. Replace "example.com" with your domain name.
example.com {
    root "/var/www/html" // Replace "/var/www/html" with the directory containing your static files
}

Basic reverse proxying

// Example configuration with reverse proxy. Replace "example.com" with your domain name.
example.com {
    proxy "http://localhost:3000/" // Replace "http://localhost:3000" with the backend server URL
}

More examples

You can find more configuration examples for common use cases in the Ferron documentation.

Building Ferron from source

You can clone the repository and explore the existing code:

git clone https://github.com/ferronweb/ferron.git
cd ferron

You can then build and run the web server using Cargo:

cargo run --manifest-path build/prepare/Cargo.toml
cd build/workspace
cargo update # If you experience crate conflicts
cargo build -r --target-dir ../../target
cd ..
cp configs/ferron.test.kdl ferron.kdl
target/release/ferron

You can also, for convenience, use make:

make build # Build the web server
make build-dev # Build the web server, for development and debugging
make run # Run the web server
make run-dev # Run the web server, for development and debugging
make smoketest # Perform a smoke test
make smoketest-dev # Perform a smoke test, for development and debugging
make package # Package the web server to a ZIP archive (run it after building it)
make package-deb # Package the web server to a Debian package (run it after building it)
make package-rpm # Package the web server to an RPM package (run it after building it)
make installer # Build installers for Ferron 2

Or a build.ps1 build script, if you're on Windows:

REM Build the web server
powershell -ExecutionPolicy Bypass .\build.ps1 Build

REM Build the web server, for development and debugging
powershell -ExecutionPolicy Bypass .\build.ps1 BuildDev

REM Run the web server
powershell -ExecutionPolicy Bypass .\build.ps1 Run

REM Run the web server, for development and debugging
powershell -ExecutionPolicy Bypass .\build.ps1 RunDev

REM Perform a smoke test
powershell -ExecutionPolicy Bypass .\build.ps1 Smoketest

REM Perform a smoke test, for development and debugging
powershell -ExecutionPolicy Bypass .\build.ps1 SmoketestDev

REM Package the web server to a ZIP archive (run it after building it)
powershell -ExecutionPolicy Bypass .\build.ps1 Package

REM Build installers for Ferron 2
powershell -ExecutionPolicy Bypass .\build.ps1 Installer

You can also create a ZIP archive that can be used by the Ferron installer:

Or if you're on Windows:

powershell -ExecutionPolicy Bypass .\build.ps1 BuildWithPackage

The ZIP archive will be located in the dist directory.

You can also cross-compile the web server for a different target:

# Replace "i686-unknown-linux-gnu" with the target (as defined by the Rust target triple) you want to build for
make build TARGET="i686-unknown-linux-gnu" CARGO_FINAL="cross"

It's also possible to use only Cargo to build the web server, although you wouldn't be able to use external modules:

cargo build -r
./target/release/ferron

For compilation notes, see the compilation notes page.
