The main release version of Automobilista has an accompanying dedicated server distribution which can be installed without the need for the machine running the server to have an account with a license for the full game. The dedicated server distribution includes only the content and binaries required to host a server and thus is much smaller than the main release. (~19Gb vs 30Gb+ at the time of writing) If you only need/want a single installation of the dedicated server and wish to install via the standard Steam desktop client open the link below on the machine you wish to install on in your browser or 'Start > Run'. steam://install/447760 If you do not wish to be tied to the desktop client or would like to maintain multiple installations, for example one modded and another clean, continue on to the SteamCMD information below. SteamCMD Valve provides the SteamCMD tool to users as a means to perform the installation, update, and validation, of games from the command line without the need for the standard Steam desktop client, making it ideal for use in server installations. It has many benefits including being scriptable, allowing automation of the process, and not being limited to a single installation of each appid as the main desktop client is. SteamCMD direct download: https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip The complete documentation for SteamCMD is location on Valve's wiki: SteamCMD - Valve Developer Community Quickstart The AutomobilistaDedicatedTemplate.zip attached to this post contains everything you need to get started with SteamCMD installs of Automobilista dedicated server. It contains the steamcmd.exe binary and two batch files to perform the install. Simply extract the contents on the machine you wish to run the server and run Server1_update.bat. This will update the included SteamCMD installation before downloading and installing the Automobilista dedicated distribution to the newly created server1 directory. Updating/Validating The Installation To update the installation run Server1_update.bat again. SteamCMD will once again update itself if required before acquiring any new files for the game installation if there are updates available. It is safe to run even when no updates are available. Running Server1_validate.bat will perform validation on the installations files. It will re-download and replace any files which have become change or corrupted. It will also download any new game updates if they are available. On our servers we typically always use the validate script to perform updates. It takes a little longer if there are no updates due to the file checking but also ensures that there are no corrupt/missing files which may cause users mismatching issues. Multiple Installations SteamCMD can be used to allow multiple installations to co-exist on the same machine. This can be useful for operational reasons or when running content that extends/modifies default content in order to not pollute your main installation. Note however that multiple installations are not required to host multiple server instances. (see Hosting Multiple Servers below) Whatever the reason, creating multiple installs form the template is as easy as duplicating the .bat files and changing the install path. For example to create an update file for Server2: 1) Copy Server1_update.bat to Server2_update.bat 2) Open Server2_update.bat and change the steamcmd line from Code: steamcmd +login anonymous +force_install_dir ../Server1 +app_update 447760 +quit to Code: steamcmd +login anonymous +force_install_dir ../Server2 +app_update 447760 +quit 3) Repeat for Server2_validate.bat 4) Run Server2_update.bat to download the latest files Hosting Multiple Servers Multiple installations are not required in order to host multiple server instances. it is however vital that each instance has it's own user profile to avoid port clashes. Each profile has it's own Multiplayer.ini which needs to have ports assigned that are different from each other running instance of the dedicated server application. The dedicated server uses the same profiles as the main game (typically in 'My Documents\Automobilista\userdata'). To create a new profile without launching the game copy an existing profile directory with a new name for the profile. If this is a brand new install of only the server and there are no existing profiles, launch AMS Dedicated.exe and exit at the mod select screen. A profile named 'DedicatedServer' will have been created which you can use as the base for any additional profiles required. More information on ports and firewall rules is available in the Automobilista Manual.
