My IoT badge for lca2019
linux.conf.au 2019 ePaper Badge
Building
To cross-compile for the Raspberry Pi you will need an
arm-unknown-linux-gnueabihf GCC toolchain and Rust component installed. On
Arch Linux I built arm-linux-gnueabihf-gcc from the AUR. Add the Rust target
with rustup target add arm-unknown-linux-gnueabihf. Then you can
cross-compile with cargo:
cargo build --release --target arm-unknown-linux-gnueabihf
After it is built copy target/arm-unknown-linux-gnueabihf/release/lca2019 to
the Raspberry Pi.
Running
View the options with ./lca2019 -h. By default it will try to bind the
webserver to port 80. You can give a regular user the permission to do this
with:
sudo setcap cap_net_bind_service=ep lca2019
Alternatively use -p to set the port to a non-privileged one.
Systemd Service
Copy lca2019.service to /etc/systemd/system/.
sudo systemctl daemon-reload
sudo setcap cap_net_bind_service=ep lca2019
sudo systemctl enable --now lca2019
Development
Auto-reloading server
To run the server during development and have it rebuild and restart when source files are changed I use watchexec:
watchexec -w src -w templates -s SIGINT -r 'cargo run -- -n -p 8080'
