Tic-Tac-Toe Server Manual


To set up the server for my Tic-Tac-Toe Online, you can run the following shell commands.

# Change this to your desired path

# Download the server script to your specified destination
sudo wget -O $TTT_SERVER_SCRIPT_PATH http://CharmySoft.com/app/ttt-python/github/ttt_server.py

# Download the upstart configuration script
sudo wget -O /etc/init/ttt-service.conf http://CharmySoft.com/app/ttt-python/github/ttt-service.conf

# Update the server script path on the downloaded upstart conf file
sudo sed -i 's|'/ttt_server.py'|'${TTT_SERVER_SCRIPT_PATH}'|' /etc/init/ttt-service.conf

After setting up the upstart configuration script, if you have installed upstart on your server machine, the server script will automatically run on system start up. And respawn will start it back up if it is killed or exits non-zero (like an uncaught exception), so the server script can always keep running on your server.

If you want to test the server script on your local machine, you can run ttt_server.py with python3:

python3 ttt_server.py [port_number]

Where the argument port_number is a 16-bit unsigned integer port number used for the TCP/IP protocol addressing. You can also run the server script with no arguments, and you will then be asked to enter the and port number.

Server Port Binding Error

If the server fails to bind the port, you will see an error message as above. You can then choose to abort, change port number, or retry, as you wish. Usually this is due to port conflicts, or the port is reserved by the system.

Server Starting Successfully

When the server is successfully started, you will see some messages as above. And then the server will be able to accept clients.

Server Running

You will be informed when clients are connected, when they get matched and start a game, when they disconnect, when some unexpected error happens, and when they finish their game, etc. Once the server gets started, it should be able to keep running without getting interrupted. Even when the clients’ connection fails, or some unexpected messages are received from the client, the server can handle those exceptions gracefully and inform you of the exceptions.

Server Log

All the information, warnings, and exceptions, will also be logged into the file ttt_server.log.

Now that you’ve set up the server. You can now go ahead and start the client program from Tic-Tac-Toe Client Manual.
