Install Dependencies Using LinuxGSM

LinuxGSM will attempt to install dependencies either by having the gmodserver user account with sudo access or running the installer as root.

user with sudo access

During the installation if the game server user has sudo permissions LinuxGSM will attempt to install any missing dependencies itself.

root user

if gmodserver is already installed run ./gmodserver install as root and LinuxGSM will automatically install missing dependencies.

Install

From the command-line do the following. Ensuring you have also installed the required dependencies.

1. Create a user and login. 
adduser gmodserver
For security best practice, ensure you set a strong password. Random password: 
su - gmodserver
2. Download linuxgsm.sh. 
curl -Lo linuxgsm.sh https://linuxgsm.sh && chmod +x linuxgsm.sh && bash linuxgsm.sh gmodserver
3. Run the installer following the on-screen instructions.
