This with Steamcmd error appears in all installations. No matter if Windows / Debian / Linux. No matter which hard drive or SSD.

During the update process the steamapps folder is deleted, then the error message "Disk write failure" appears.

Don't EVER run ANYTHING related to server applications as root. Dedicated user, dedicated home directory, but NEVER root, and most certainly not /root/. And stop using chmod 777 for anything. You're breaking every security your server provides. At max use 755.

Bloody hell. Morons all around.

Apart from that:

(you might have to recheck, I'm a Debian SysOp and don't use CentOS)
useradd --system --home-directory /opt/csgo csgo

su csgo /usr/games/steamcmd +login anonymous +force_install_dir /opt/csgo +app_update 740 validate +quit

This should install your server.
But, from professional to pebcak: Leave installing and running servers to people who have at least basic knowledge how to set up a server.

Hello,

the problem occurred to many users and had to do with an update of steam, a day later it was fixed.


Anyone who runs a game server via root shouldn't be surprised if the user root gets cheated at some point.

So pleased to see folks givin' good security advice here! Too often I see threads like this where the first suggestions are incredibly bad advice like "just run as admin" or "disable the firewall".
