Installing SteamCMD for Steam Game Servers
A detialed overview on how to install SteamCMD for Game Servers in any environment.
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.
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.As the root user, create the steam user:useradd -m steam
- 2.Go into its home folder:cd /home/steamPackage from repositories
- 3.It's recommended to install the SteamCMD package from your distribution repositories, if available:Ubuntu/Debiansudo apt-get install steamcmdRedHat/CentOSyum install steamcmdArch Linux: install steamcmd from the AUR.
- 4.Link the steamcmd executable:ln -s /usr/games/steamcmd steamcmdManually
- 5.Before you begin, you must first install the dependencies required to run SteamCMD:Ubuntu/Debian 64-Bitsudo apt-get install lib32gcc1RedHat/CentOSyum install glibc libstdc++RedHat/CentOS 64-Bityum install glibc.i686 libstdc++.i686
- 6.As the root user, escalate to the steam user:su - steamIf 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.Create a directory for SteamCMD and switch to it.mkdir ~/Steam && cd ~/Steam
- 8.Download and extract SteamCMD for Linux.curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -
- 1.Open Terminal.app and create a directory for SteamCMD.mkdir ~/Steam && cd ~/Steam
- 2.Download and extract SteamCMD for OS X.curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_osx.tar.gz" | tar zxvf -
On first run, SteamCMD will automatically update and enter you into a Steam > prompt. Type help for more information.
Open a Command Prompt and start SteamCMD.
Open a terminal and start SteamCMD.
If you installed it using the package from repositories:
If you installed it manually:
To download most game servers, you can login anonymously.
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).
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.
- 1.Start SteamCMD and log in.
- 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.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
validateto the command. To download a beta branch, use the
-beta <betaname>option – for example, the HLDS beta branch is named
betaand 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 validateExample: 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_updatecommand before all the required files are successfully installed. Simply run
app_update 90 validatemultiple times until no more updates take place.Example: Install and validate beta version of HLDS (Half-Life):app_update 90 -beta beta validateExample: install and validate beta version of the Counter Strike: Source dedicated server:app_update 232330 -beta prerelease validateExample: 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 branchapp_update 4940 -beta alpha -betapassword natsel validate
- 4.Once finished, type
quitto properly log off of the Steam servers.quit
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.
There are two ways to automate SteamCMD. (Replace
./steamcmd.shon Linux/OS X.)
￼> Note: When using the
-betaoption 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
- 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 1login <username> <password> //for servers which don't need a login//login anonymousforce_install_dir ../csgo_dsapp_update 740 validatequit
- 2.Run SteamCMD with the
+runscriptoption, referring to the file you created previously. Example:steamcmd +runscript csgo_ds.txt
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
@sSteamCmdForcePlatformTypevariable. (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:
app_update 740 validate
The supported values are

There are now 70+ different game servers supported and rising. For a full list visit the website.
The following script was tested on Debian Wheezy.
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.Make the filenano updateserver.sh
- 2.Paste in the code
- 3.Modify the code, add
at least1 game to the
- 4.Close the file with
O, followed by
↵ Enterand concluding with
- 5.Give the file execute rights for the userchmod u+x ./updateserver.sh
- 6.Run the file./updateserver.shThe file will auto-download SteamCMD, update it and install all chosen games (up to 4). Run the file again to update the games.
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.
steamcmd +login <username> <password>
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:
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 install lib32gcc1
yum install glibc.i686 libstdc++.i686
pacman -S lib32-gcc-libs
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.
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
ln -s steamcmd/linux32/steamclient.so ~/.steam/sdk32/steamclient.so
Some users may get a
ulimiterror (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
ulimitvalues after startup (or beyond a limit set by
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,
1024is the current value.
rootcan also modify the limits in the
In most instances you will simply get a warning message however it will not stop SteamCMD from running.
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.
