Configuration and Running

Signal server, once compiled, needs only a few dependencies and doesn't require a lot of system resources.

Runtime dependencies

To run the signal server, the following libraries are needed (corresponding packages for Ubuntu 18.04 are in the parentheses):

In Ubuntu you can install them using a single command:

sudo apt install libgmp10 libssl1.1

You can run the server binary with default settings (port 7777, TLS disabled) using

./signal-server

The server becomes available on ws://<domain>:7777, eg. ws://localhost:7777.

You can change the default port using

./signal-server <port>

To run in TLS mode, the command looks like

./signal-server --cert "path/to/certificate.pem" --key "path/to/private-key.pem" 443

The final address of your server will be wss://<domain>. There is no need to specify port because 443 is default for HTTPS/WSS.
