Installing SteamCMD for Steam Game Servers

A detialed overview on how to install SteamCMD for Game Servers in any environment.
​

SteamCMD

The Steam Console Client or SteamCMD is a command-line version of the Steam client. Its primary use is to install and update various dedicated servers available on Steam using a command-line interface. It works with games that use the SteamPipe content system. All games have been migrated from the deprecated HLDSUpdateTool to SteamCMD.

Downloading SteamCMD

Windows

  1. 1.
    Create a folder for SteamCMD.
    For example
    C:\steamcmd
  2. 2.
    Download SteamCMD for Windows: https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip​
  3. 3.
    Extract the contents of the zip to the folder.

Linux

Create a user account named steam to run SteamCMD safely, isolating it from the rest of the operating system. Do not run steamcmd while operating as the root user - to do so is a security risk.
  1. 1.
    As the root user, create the steam user:
    useradd -m steam
  2. 2.
    Go into its home folder:
    cd /home/steam
    Package from repositories
  3. 3.
    It's recommended to install the SteamCMD package from your distribution repositories, if available:
    Ubuntu/Debian
    sudo apt-get install steamcmd
    RedHat/CentOS
    yum install steamcmd
    Arch Linux: install steamcmd from the AUR.
  4. 4.
    Link the steamcmd executable:
    ln -s /usr/games/steamcmd steamcmd
    Manually
  5. 5.
    Before you begin, you must first install the dependencies required to run SteamCMD:
    Ubuntu/Debian 64-Bit
    sudo apt-get install lib32gcc1
    RedHat/CentOS
    yum install glibc libstdc++
    RedHat/CentOS 64-Bit
    yum install glibc.i686 libstdc++.i686
  6. 6.
    As the root user, escalate to the steam user:
    su - steam
    If you're not logging in as root and you instead use sudo to perform administration, escalate to the steamuser as follows:
    sudo -iu steam
  7. 7.
    Create a directory for SteamCMD and switch to it.
    mkdir ~/Steam && cd ~/Steam
  8. 8.
    Download and extract SteamCMD for Linux.
    curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

OS X

  1. 1.
    Open Terminal.app and create a directory for SteamCMD.
    mkdir ~/Steam && cd ~/Steam
  2. 2.
    Download and extract SteamCMD for OS X.
    curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_osx.tar.gz" | tar zxvf -

Running SteamCMD

On first run, SteamCMD will automatically update and enter you into a Steam > prompt. Type help for more information.

Windows

Open a Command Prompt and start SteamCMD.
cd C:\steamcmd
steamcmd

Linux/OS X

Open a terminal and start SteamCMD.
If you installed it using the package from repositories:
cd ~
steamcmd
If you installed it manually:
cd ~/Steam
./steamcmd.sh

SteamCMD Login

Anonymous

To download most game servers, you can login anonymously.
login anonymous

With a Steam account

Some servers require you to login with a Steam Account.
> Note: For security reasons it is recommended that you create a new Steam account just for your dedicated servers.
> Note: A user can only be logged in once at any time (counting both graphical client as well as SteamCMD logins).
login <username>
Next enter your password.
If Steam Guard is activated on the user account, check your e-mail for a Steam Guard access code and enter it. This is only required the first time you log in (as well as when you delete the files where SteamCMD stores the login information).
You should see a message stating that you have successfully logged in with your account.

Downloading an app

  1. 1.
    Start SteamCMD and log in.
  2. 2.
    Set your app install directory. (Note: use forward slashes for Linux/OS X and backslashes for Windows.)
    force_install_dir <path>
    e.g. a directory named cs_go inside the current directory:
    force_install_dir ./cs_go/
    For Windows: force_install_dir c:\cs_go\
  3. 3.
    Install or update the app using the app_updatecommand (supplying a Steam Application ID). Please check here for the dedicated server list: Dedicated server list. To also validate the app, add validate to the command. To download a beta branch, use the -beta <betaname> option – for example, the HLDS beta branch is named beta and the SrcDS beta branch is named prerelease. Some beta branches are protected by a password; to be able to download from them, also add the -betapassword <password> option.
    app_update <app_id> [-beta <betaname>] [-betapassword <password>] [validate]
    HLDS is a special case: the App ID is always 90 and a mod must be chosen first. This is done by setting the app config option mod to the requested value.
    app_set_config <app_id> <option_name> <option_value>
    Example: Install and validate the Counter Strike: Global Offensive dedicated server:
    app_update 740 validate
    Example: Install and validate HLDS with Team Fortress Classic:
    app_set_config 90 mod tfc app_update 90 validate
    Bug: HLDS (appid 90) currently requires multiple runs of the app_update command before all the required files are successfully installed. Simply run app_update 90 validate multiple times until no more updates take place.
    Example: Install and validate beta version of HLDS (Half-Life):
    app_update 90 -beta beta validate
    Example: install and validate beta version of the Counter Strike: Source dedicated server:
    app_update 232330 -beta prerelease validate
    Example: install and validate a private beta version of the Natural Selection 2 dedicated server (name alpha, password natsel): [beta name] is the name of the private beta branch [beta code] is the password for the private beta branch
    app_update 4940 -beta alpha -betapassword natsel validate
  4. 4.
    Once finished, type quit to properly log off of the Steam servers.
    quit

Validate

validate
Validate is a command that will check all the server files to make sure they match the SteamCMD files. This command is useful if you think that files may be missing or corrupted.
> Note: Validation will overwrite any files that have been changed. This may cause issues with customized servers. For example, if you customize mapcycle.txt, this file will be overwritten to the server default. Any files that are not part of the default installation will not be affected.
It is recommended you use this command only on initial installation and if there are server issues.

Supported Servers

A list of known servers that use SteamCMD to install is available on the Dedicated Servers List page. Note that any extra commands listed need to be executed before the app_update line.

Automating SteamCMD

There are two ways to automate SteamCMD. (Replace steamcmd with ./steamcmd.sh on Linux/OS X.)

Command line

> Note: When using the -beta option on the command line, it must be quoted in a special way, such as +app_update "90 -beta beta".
> Note: If this does not work, try putting it like "+app_update 90 -beta beta" instead.
Append the commands to the command line prefixed with plus characters, e.g.:
steamcmd +login anonymous +force_install_dir ../csgo_ds +app_update 740 +quit
To install a specific game mod for HL1, such as Counter-Strike: Condition Zero:
steamcmd +login anonymous +force_install_dir ../czero +app_set_config 90 mod czero +app_update 90 +quit
For a game that requires logins, like Killing Floor:
steamcmd +login <username> <password> +force_install_dir c:\KFServer\ +app_update 215350 +quit

Creating a script

  1. 1.
    Put your SteamCMD commands in a text file. (You may add comments which start with //.) Example:
    // update_csgo_ds.txt
    //
    @ShutdownOnFailedCommand 1 //set to 0 if updating multiple servers at once
    @NoPromptForPassword 1
    login <username> <password> //for servers which don't need a login
    //login anonymous
    force_install_dir ../csgo_ds
    app_update 740 validate
    quit
  2. 2.
    Run SteamCMD with the +runscript option, referring to the file you created previously. Example:
    steamcmd +runscript csgo_ds.txt

Cross-Platform Installation

It is possible to choose the platform for which SteamCMD should download files, even if it isn't the platform it is currently running on. This is done using the @sSteamCmdForcePlatformType variable. (Yes, those are two "s"es at the beginning of the variable name.) For example, to download the Windows CSGO dedicated server on Linux, you can run the following command:
./steamcmd.sh +@sSteamCmdForcePlatformType windows +login anonymous +force_install_dir ../csgo_ds +app_update 740 validate +quit
or use the following script:
@ShutdownOnFailedCommand 1
@NoPromptForPassword 1
@sSteamCmdForcePlatformType windows
login anonymous
force_install_dir ../csgo_ds
app_update 740 validate
quit
The supported values are windows, macos and linux.

The following script was tested on Debian Wheezy.
View and download here: http://pastebin.com/hcpMpmaZ​
Installation
To make this script work, we need a location. Preferably you created a user (e.g. steam) with it's own home directory (/home/steam) and are logged in as it via SSH, tty or using su.
  1. 1.
    Make the file
    nano updateserver.sh
  2. 2.
    Paste in the code
  3. 3.
    Modify the code, add at least 1 game to the DL_SV*= rows.
  4. 4.
    Close the file with Ctrl+O, followed by ↵ Enter and concluding with Ctrl+X.
  5. 5.
    Give the file execute rights for the userchmod u+x ./updateserver.sh
  6. 6.
    Run the file
    ./updateserver.sh
    The file will auto-download SteamCMD, update it and install all chosen games (up to 4). Run the file again to update the games.

Known issues

ERROR! Failed to install app 'xxxxxx' (No subscription)

If you get the 'No subscription' error, the game/server you are trying to download either requires a login or that you have purchased the game. You will therefore have to log in with a Steam username and password – if that doesn't help, you may need to purchase a copy of the game on Steam first. See Dedicated Servers List.
Note: For security reasons it is recommended that you create a new Steam account just for your dedicated servers.
For example
steamcmd +login <username> <password>

32-bit libraries on 64-bit Linux systems

Since SteamCMD is a 32-bit binary, 32-bit libraries are required.
The following error may occur:
steamcmd: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
The resolution depends on your distro:

Debian based distributions (Ubuntu, Mint, etc.)

sudo apt-get install lib32stdc++6
> Note: ia32-libs are not required to install SteamCMD; lib32gcc1 is enough.
With Debian 7 "Wheezy" you may encounter this error:
The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch but it is not installable E: Unable to correct problems, you have held broken packages.
To fix this, do the following:
dpkg --add-architecture i386
apt-get update
apt-get install lib32gcc1

Red Hat based distributions (RHEL, Fedora, CentOS, etc.)

yum install glibc.i686 libstdc++.i686

Arch Linux

Don't forget to first enable the multilib repository.
pacman -S lib32-gcc-libs

Login Failure: No Connection

On linux servers, you may experience a "Login Failure: No Connection" error. This is related to missing iptables rules. You will want something along these lines:
iptables -A INPUT -p udp -m udp --sport 27000:27030 --dport 1025:65355 -j ACCEPT iptables -A INPUT -p udp -m udp --sport 4380 --dport 1025:65355 -j ACCEPT
On Windows servers, you may experience "SteamUpdater: Error: Download failed: http error 0" and "SteamUpdater: Error: Steam needs to be online to update. Please confirm your network connection and try again.". This is usually fixed by checking "Automatically detect settings" in IE (Internet Explorer) through the lan settings in the Internet option menu. 1. Open Internet Explorer (IE). 2. Click on Tools → Internet Options 3. Click on the Connections tab 4. At the bottom, you should see Local Area Network (LAN) Settings. 5. Check the first box (Automatically detect settings) 6. Hit OK, and Apply. Try running the SteamCMD again; if it still doesn't work. try lowering your Internet Security level zone to medium or lower. You can find that in the Security tab in Internet Options.

SteamCMD startup errors

Unable to locate a running instance of Steam

You may get the following error when starting a server with Linux:
[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.dll.
Resolve the issue by linking steamclient.so to the ~/.steam/sdk32/steamclient.so directory:
ln -s steamcmd/linux32/steamclient.so ~/.steam/sdk32/steamclient.so

ulimit Linux startup error

Some users may get a ulimit error (no permission/cannot open file) while script is starting up. This error caused by a low setting of the -nparameter (number of file descriptors) of ulimit. SteamCMD uses standard commands inside of the initialization shell script to change the ulimitautomatically, but some servers may forbid increasing ulimit values after startup (or beyond a limit set by root).
This can be fixed by changing the file descriptor number ulimit:
ulimit -n 2048
If an error appears (no permission), you will have to log in as root to change the parameter. To check the current setting, type ulimit -a; the system will reply with many rows, you need to find one:
open files (-n) 1024
In this case,1024 is the current value.
root can also modify the limits in the /etc/security/limits.conf file.
In most instances you will simply get a warning message however it will not stop SteamCMD from running.

Only the HLDS engine is downloaded

When trying to download a HL1 mod like TFC, initially it only downloads the engine files of the HLDS, but not the mod. This happens with both the regular version and the beta. You may have to try multiple times until all the required files are downloaded, but once this is done, the files should update correctly next time.
Just deleting the appmanifest files, without downloading replacements from a third party, may work as well! You will get an error at first though, complaining that something went wrong, which is due to the deleted files.
On a side note, for some reason CS is always installed as well.
