Command-line tool that installs and runs several CS2 servers on one Linux machine

csm installs CS2 with SteamCMD, puts [Ready Up](https://github.com/Auto-Tournament/ready-up), the native CS2 plugin, on every server, runs each server in its own tmux session and keeps the game and plugins updated. It's for LAN organisers, small leagues and anyone running [Auto Tournament](https://github.com/Auto-Tournament/auto-tournament), which can then start, stop, create and update the servers itself. ## Features - Interactive terminal UI and a plain CLI (`csm help`) - Several CS2 servers on one machine, each in its own tmux session - Instance mode: every server runs one shared install, so ten servers take about the disk space of one - Ready Up installed and kept on its release channel on every server (no Metamod, no CounterStrikeSharp) - Automatic game and plugin updates from cron, never in the middle of a match - Update hold while a tournament runs, set by you or by Auto Tournament - `csm status`: process, map, phase, score and players of every server - Host agent (`csm link`): Auto Tournament starts, stops, creates and updates servers on this machine - Runs as its own user without sudo after a one-time `sudo csm setup-host` ## Install On a Linux server, log in as the account the servers will run as, download the latest release to `/usr/local/bin/csm`, set up the host once, and start the installer: ```bash arch=$(uname -m); \ case "$arch" in \ x86_64) asset="csm-linux-amd64" ;; \ aarch64|arm64) asset="csm-linux-arm64" ;; \ *) echo "Unsupported architecture: $arch" && exit 1 ;; \ esac; \ tmp=$(mktemp); \ curl -L "https://github.com/Auto-Tournament/cs2-server-manager/releases/latest/download/$asset" -o "$tmp" && \ sudo install -m 0755 "$tmp" /usr/local/bin/csm && \ rm "$tmp" && \ sudo csm setup-host # once: packages and lingering for your account ``` Then run csm without sudo. The installer sets up Ready Up and asks for its license: ```bash csm # the interactive TUI installer ``` csm keeps its data in your home folder and logs to `~/logs/csm.log`. Configs you put in `overrides/` survive game and plugin updates. Running without sudo, and what to do when `steamcmd` can't be installed: [docs/INSTALL.md](docs/INSTALL.md). ## Usage ```bash csm # interactive TUI csm status # every server: process, map, phase, score, players csm start [server] # start all servers, or one csm stop [server] # refuses while a Ready Up match is live csm update-game # update CS2 csm update-plugins # install or update the plugin stack on every server csm link

 # let Auto Tournament control this machine
csm link --name     # and another platform (each sees only its own servers)
csm license set  # a commercial license key (free for non-commercial use)
csm license cap --link  5      # this platform may create at most 5 servers here
```

### Several platforms on one host

A hosting provider can link one machine to several Auto Tournament platforms
(`csm link --name  ...`). Every server belongs to the platform that
created it; each platform sees, starts, stops, updates and removes only its own
servers, within the cap the host sets for it (`csm license cap --link`). Servers
made before the second link belong to the first. Updates are held while any
platform asks for a hold. `csm link status` lists the links and their servers;
`csm unlink ` removes one and gives its servers back to the first link.

Licenses: each platform's license goes to the Ready Up config of the servers it
owns. When the host sets a key of its own (`csm license set`), that key covers
every server here and is never overwritten by a platform; those servers count
toward the host's license, not the platform's.

Every command, update holds and the host agent: [docs/USAGE.md](docs/USAGE.md).
