If you choose not to
configure your server to use a workshop collection, you can use a mapgroup instead.
First, you'll have to decide which maps you want on your server. You can find many good maps at
GameBanana, or you can download maps from the
steam workshop. Download any maps you want to a folder of your choice.
Upload the maps to your game server. Put these maps in /csgo/maps.
Now, you'll have to edit GameModes_Server.txt to include all the maps you want, in the order you want to play them. Check out
this thread for an example of GameModes_Server.txt.
Now, instead of using the workshop commands for your server start command line, you'll need to use the following mapgroup cvars:
Code:
+mapgroup mp_bomb +map de_dust2
Of course, you should configure those to your specifications.
