===Install Terraria Server:===

  * Add a port forwarding rule in your router for tcp and udp port 7777 to the IP of the VM
  * Using an SSH client, connect to <hostname>:50001 then run:

<code bash>
# Allow port 7777 through iptables
sed -i "s/COMMIT/-A INPUT -p tcp -m tcp --dport 7777 -j ACCEPT\n-A INPUT -p udp -m udp --dport 7777 -j ACCEPT\nCOMMIT/" /etc/systemd/scripts/ip4save
reboot  # And then reconnect the SSH client

tdnf install unzip tmux less

# Download and place the server in /terraria (Check the PC Dedicated Server link at the bottom of https://terraria.org for the latest server file and change all the "1402" references to the correct version)
cd /tmp
curl --output terraria-server.zip https://terraria.org/system/dedicated_servers/archives/000/000/036/original/terraria-server-1402.zip?1589675482
unzip terraria-server.zip
mv 1402/Linux /terraria/server

# Remove temp files
rm terraria-server.zip
rm -r 1402

# Allow the server to be executed and set the config
chmod u+x /terraria/server/TerrariaServer*

vim /terraria/serverconfig.txt
# Press i, then paste the following into the window (replacing the password):
autocreate=2
worldname=World
difficulty=2
maxplayers=16
port=7777
password=password1234
worldpath=/terraria/worlds/
##
<esc> :wq

# Start the server
tmux new -s terraria "/terraria/server/TerrariaServer.bin.x86_64 -config /terraria/serverconfig.txt" \; pipe-pane -o -t terraria "cat >>/terraria/server.log"
</code>

  * Either use ''<Ctrl+b> d'' to detach the tmux client, or use the ''-d'' flag in the tmux command to start it disconnected.
  * Either re-attach to the session with ''tmux a -t terraria'', and type ''exit'', or run ''tmux send-keys -t terraria "exit" Enter'' to shutdown the server.
  * Edit the VM note and append the following:
<code>
7777/both Terraria (Port Forwarded)

Run with:
tmux new -d -s terraria "/terraria/server/TerrariaServer.bin.x86_64 -config /terraria/serverconfig.txt" \; pipe-pane -o -t terraria "cat >>/terraria/server.log"

Stop with:
tmux send-keys -t terraria "exit" Enter
