Add systemd example for Translator

[Sjors]

Create a user stratum, install rust and clone the repo. And then use this systemd service to have it run automatically.

[Sjors]

I assume there's a way to install the binary and avoid cargo run?

[xraid]

after cargo build the executable would be in target folder need adjust ExecStart in config

or have cp /usr/local/bin

[Sjors]

Updated to us cargo build -p translator --release and point to the target dir.

It would be nice if the working directory could just be some random temp directory, but it won't start when I do that.

[xraid]

$USER/src/stratum/target/release/translator

?

# cargo build -p translator --release && cp target/release/translator /usr/local/bin

?

[Sjors]

/usr/local/bin is not accesible for my stratum user (no sudo rights).

~/.cargo/bin would be a better location, but I couldn't get the something like cargo install to work. Manually copying the binary feels like a hack, but it's an option.

[Sjors]

Not sure if $USER works inside a systemd service file?

maybe add a installTranslarorProxy.sh to do the dance ?

[Sjors]

Isn't there a more Rust'y way to do that?

[xraid]

the systemd needs install to so maybe a .sh is right

https://doc.rust-lang.org/cargo/commands/cargo-install.html

brings us to maybe have a README.md in each roles folder with alternatives and general documentation

[Sjors]

I usually manually install systemd services. Using a script is not that convenient, since it would need sudo rights.

I made a separate issue for cargo install: #450

[Sjors]

I wrote:

See #451.

Note to self: update instructions to put proxy-config.toml somewhere else and point to it with -c ~/.stratum/proxy-config.toml
