cPGS garrysmod won't start
I had problems getting garrysmod to start.
The problems started with "srcds_linux: error while loadin g shared libraries: libtier0.so: cannot open shared object file ..", then I started getting "pid 's current affinity mask: ff pid 's new affinity mask: ff Game server has exited." when I tried to start the server.
I have built the following script for centos/rhel distributions running 64bit that are having this problem. This also works with cloudlinux.
I cannot guarantee this will work for you, but hopefully it does!
wget http://ganey.co.uk/uploads/cpgsgmodfix.sh
./cpgsgmodfix.sh username
where username is the username of the user account in cpanel for the game server in /home/
