#!/bin/bash ### WARNING -- READ NOW -- THAT MEANS YOU! # This is a TEMPLATE service script and will NOT WORK as is. # # You MUST create a copy of this script for EACH of your SvenDS profiles you # intend to run, and replace the following strings (with `sed` or your # favourite text editor) as follows: # # $$GAME_PATH$$ Path to your base SvenDS installation as delivered by # SteamCMD, e.g. "/home/svc.svends/SvenDS-public". # # $$SERVER_LOGIN$$ User on the system of which will be running the SvenDS # instance. (NEVER use "root" for this!) # # $$MOD_NAME$$ The name of the SvenDS mod, almost always "svencoop". # # $$PROFILE_NAME$$ The folder name of your SvenDS profile, e.g. "public1". # This will form part of the system service name prefixed # with "svends-", e.g. "svends-public1". # # $$PROFILE_PATH$$ The relative path of your SvenDS profile relative to the # mod folder, e.g. "servers/public1". Ensure that a "logs" # folder exists within this. # # $$PROFILE_ADDRESS$$ The IP address SvenDS will listen on. (This must be # assigned to a NIC on this system. Do not specify an # external or public IP address assigned to a NAT gateway. # # $$PROFILE_PORT$$ The UDP port SvenDS will listen on. # # $$MAX_PLAYERS$$ The number of player slots SvenDS will create. (2-32) # # $$DEFAULT_MAP$$ The map SvenDS should start running. This is best set as # "_server_start", as this will give your SvenDS plug-ins # an opportunity to initialise, along with the map cycle. # # N.B. The IP address and port when combined must be unique for each SvenDS # profile running concurrently. # # If you seriously know what you're doing you're welcome to edit this script to # trim out variables you'll never need (potentially "$$PROFILE_ADDRESS$$".) # # After you have completed this place this script in EACH of your SvenDS profile # folders, then call it as root with the "install" action. (You cannot install # the service as the non-root user of which will be running SvenDS.) # # Ensure you have GNU Screen installed too. The SvenDS instances will get their # own Screen instance running as the user specified, so you can attach to it at # any point to see and interact with the SvenDS console at runtime. ### WARNING -- READ NOW -- THAT MEANS YOU! ### BEGIN INIT INFO # Provides: svends-$$PROFILE_NAME$$ # Default-Start: 2 3 4 5 # Default-Stop: 1 # Short-Description: Sven Co-op dedicated server: Profile $$PROFILE_NAME$$ ### END INIT INFO set -e DAEMON="$$GAME_PATH$$/svends_run" NAME="svends-$$PROFILE_NAME$$" PATH="/sbin:/bin:/usr/sbin:/usr/bin:$$GAME_PATH$$" LOGFILE="/var/log/svends-$$PROFILE_NAME$$.log" CHROOT="$$GAME_PATH$$" USER=$(whoami) test -x "${DAEMON}" || exit 1 if [ ! -e "${LOGFILE}" ]; then touch "${LOGFILE}" chmod 640 "${LOGFILE}" chown root:adm "${LOGFILE}" fi if [ ! -d "${CHROOT}" ]; then mkdir -p -m 0755 "${CHROOT}" fi BIN_INTERFACE="/usr/bin/screen -AdmS ${NAME}" DIR_GAME="$$GAME_PATH$$" BIN_GAME="$$GAME_PATH$$/svends_run" SERVICE_USER="$$SERVER_LOGIN$$" SERVICE_SCRIPT="$$PROFILE_PATH$$/service.sh" SERVICE_SCRIPT_FILE="/etc/init.d/${NAME}" FILE_PID="$$PROFILE_PATH$$/$$PROFILE_NAME$$.pid" FILE_SCREEN_PID="$$PROFILE_PATH$$/$$PROFILE_NAME$$-screen.pid" MOD_NAME="$$MOD_NAME$$" PROFILE_NAME="$$PROFILE_NAME$$" LISTEN_ADDRESS="$$PROFILE_ADDRESS$$" LISTEN_PORT=$$PROFILE_PORT$$ MAX_PLAYERS=$$SERVER_PLAYERS$$ MAP_NAME="$$DEFAULT_MAP$$" LAUNCH_PARAMS="-console -game ${MOD_NAME} +ip \"${LISTEN_ADDRESS}\" -port ${LISTEN_PORT} +maxplayers ${MAX_PLAYERS} \ +servercfgfile \"$$PROFILE_PATH$$/server.cfg\" +logsdir \"$$PROFILE_PATH$$/logs\" -pidfile \"${FILE_PID}\" \" +log on +map \"${MAP_NAME}\"" case "$1" in start) printf "Starting \"${NAME}\"...\n\n" if [ $EUID -ne 0 -a "${USER}" != "${SERVICE_USER}" ]; then printf "[Error] Cannot start: Must be root or user ${SERVICE_USER}.\n" exit 100 fi if [ -f "${FILE_SCREEN_PID}" ]; then printf "[Error] Cannot start: Already running.\n" exit 1 fi if [ ! -f "${BIN_GAME}" ] || [ ! -x "${BIN_GAME}" ]; then printf "[Error] Cannot start: Server binary missing or not executable.\n" exit 1 fi cd "${DIR_GAME}" if [ $EUID -ne 0 ]; then $BIN_INTERFACE "${BIN_GAME}" $LAUNCH_PARAMS else sudo -H -u "${SERVICE_USER}" $BIN_INTERFACE "${BIN_GAME}" $LAUNCH_PARAMS fi sleep 1 ps -ef | grep SCREEN | grep "${NAME}" | grep -v grep | awk '{ print $2 }' > "${FILE_SCREEN_PID}" printf "Screen process ID file: ${FILE_SCREEN_PID}\n" ;; stop) printf "Stopping \"${NAME}\"...\n\n" if [ $EUID -ne 0 -a "${USER}" != "${SERVICE_USER}" ]; then printf "[Error] Cannot stop: Must be root or user ${SERVICE_USER}.\n" exit 100 fi if [ ! -f "${FILE_SCREEN_PID}" ]; then printf "[Error] Cannot stop: Not running.\n" exit 1 fi for PID in $(cat "${FILE_SCREEN_PID}"); do printf "Killing process ID ${PID}...\n" kill -TERM "${PID}" break done printf "Removing Screen process ID file...\n" rm -f "${FILE_SCREEN_PID}" screen -wipe 1> /dev/null 2> /dev/null ;; restart) $0 stop $0 start ;; status) if [ -f "${FILE_SCREEN_PID}" ]; then printf "Service is running.\n" else printf "Service is not running.\n" fi ;; install) if [ $EUID -ne 0 ]; then printf "[Error] Service installation/uninstallation can only be done as root.\n" exit 100 fi if [ -f "${SERVICE_SCRIPT_FILE}" ]; then printf "[Warning] Service already installed, reinstalling.\n" if [ -f "${FILE_SCREEN_PID}" ]; then $0 stop fi fi cp "${SERVICE_SCRIPT}" "${SERVICE_SCRIPT_FILE}" printf "Service \"${NAME}\" installed.\n" $0 start ;; uninstall) if [ $EUID -ne 0 ]; then printf "[Error] Service installation/uninstallation can only be done as root.\n" exit 100 fi if [ ! -f "${SERVICE_SCRIPT_FILE}" ]; then printf "[Error] Cannot uninstall: Service not installed.\n" fi if [ -f "${FILE_SCREEN_PID}" ]; then $0 stop fi rm "${SERVICE_SCRIPT_FILE}" printf "Service \"${NAME}\" uninstalled.\n" ;; *) if [ $EUID -ne 0 -a "${USER}" != "${SERVICE_USER}" ]; then printf "[Error] Cannot use: Must be root or user ${SERVICE_USER}.\n" exit 100 fi if [ $EUID -ne 0 ]; then printf "Usage: ${0} start|stop|restart|status\n" else printf "Usage: ${0} start|stop|restart|status|install|uninstall\n" fi ;; esac
