- These steps don't vary based on what kind of computer you have.
|
||||
- You can easily start over if you mess up (just delete the instance).
|
||||
- You can easily change the server's settings and manage it from anywhere.
|
||||
- The server can continue to run even if you turn off your PC.
|
||||
|
||||
The downside to this method is that it does technically cost money. You will have to provide a payment method with Google. However, there is a one-year trial which gives $300 in credits, and the smallest instance is about $5 a month.

## Getting Started with Google Cloud

Google makes it very easy to set up a server instance in the cloud. First, [sign up for an account with Google Cloud](https://cloud.google.com/). You should see this popup to let you know you've received $300 in trial credits:
|
||||
|
||||
|
||||
|
||||
|
||||
Then, you can access your cloud account from the [Google Cloud Console](https://console.cloud.google.com/). Google has a LOT of powerful tools and resources, but most of them are designed for larger businesses and not relevant to this guide, so don't get overwhelmed.
|
||||
|
||||
Click on the `Compute Engine` tab, and then click on the `Create Instance` button to create a new VM instance.
|
||||
|
||||
* Name it if you like. The default regon and zone are fine.
|
||||
* Select the machine type. The default is a 2-core, 4GB memory machine, which is way overkill for what we want. Select the series N1, machine type `f1-micro`, which at time of writing is currently priced at $4.88/month or $0.01/hour. Even this is more than what you need for a DLU server but smaller instances aren't available.
|
||||
* Scroll to the bottom and click Create.
|
||||
|
||||
Once the instance is ready, click it, then click SSH to connect to your instance. You will then see a browser window containing a terminal.
|
||||
|
||||
Congratulations! What you've essentially done is reserve a tiny spot on Google's massive server farm, and created a Linux computer in it. We're going to build and install Darkflame Universe on here, and you and your friends will be able to connect and play the game.
|
||||
|
||||
## Configuring the Server's Firewall
|
||||
|
||||
Before we get started building the server, we need to configure the server's firewall. Follow these steps:
|
||||
|
||||
* Click 'Compute Engine' to move back to the Compute Engine homepage.
|
||||
* Under Related Actions, click 'Set up Firewall rules'
|
||||
* Click 'Create Firewall Rule' at the top.
|
||||
|
||||
We're going to create a set of Firewall rules that allow access to the server.
|
||||
|
||||
* Set the name to `darkflame-server`.
|
||||
* Add `darkflame-server` to the list of target tags. We're going to assign this tag to our server later.
|
||||
* Set the Source IPv4 ranges to `0.0.0.0/0`. This represents all IP addresses, meaning this rule will allow any incoming IP.
|
||||
* Under Protocols and ports, check `TCP` and enter the string `1001, 2000, 2005, 3000-4000, 5000`. This will allow access to the auth server, master server, chat server, world servers, and account manager.
|
||||
|
||||
Now lets assign these rules to the server.
|
||||
|
||||
* Move back to the home of your Google Cloud project (which currently contains your cloud instance).
|
||||
* Click 'Compute Engine'. You should see your `darkflame-instance` listed. Click on it.
|
||||
* Click 'Edit' at the top.
|
||||
* Scroll down to 'Network tags' and enter `darkflame-server`.
|
||||
* Scroll to the bottom and click 'Save'.
|
||||
|
||||
## Setup the MySQL Database
|
||||
|
||||
Run these commands, one at a time, in order.
|
||||
|
||||
```
|
||||
sudo apt-get update
|
||||
sudo apt-get install -y python3 python3-pip build-essential gcc libssl-dev default-mysql-server zlib1g zlib1g-dev sqlite git gpg wget
|
||||
|
||||
# Install the latest cmake
|
||||
sudo apt remove -y --purge --auto-remove cmake
|
||||
pip3 install cmake --upgrade
|
||||
export PATH="$HOME/.local/bin:$PATH"
|
||||
|
||||
# Allocate swap space so we don't run out of memory while building.
|
||||
sudo fallocate -l 2G /swapfile
|
||||
sudo chmod 600 /swapfile
|
||||
sudo mkswap /swapfile
|
||||
sudo swapon /swapfile
|
||||
sudo swapon -s
|
||||
|
||||
sudo mysql -u root
|
||||
```
|
||||
|
||||
The last command will start a MariaDB shell. Enter the following commands one at a time (be sure to change the password on the first line to something more secure):
|
||||
|
||||
```
|
||||
CREATE OR REPLACE USER darkflame IDENTIFIED BY 'password';
|
||||
CREATE OR REPLACE DATABASE darkflame;
|
||||
EXIT;
|
||||
```
|
||||
|
||||
You will now have an empty database ready for later.
|
||||
|
||||
## Download and Build the Server
|
||||
|
||||
Next, run these commands one at a time to download and build the server:
|
||||
|
||||
```
|
||||
git clone --recursive https://github.com/DarkflameUniverse/DarkflameServer
|
||||
cd DarkflameServer
|
||||
chmod +x build.sh
|
||||
./build.sh
|
||||
```
|
||||
|
||||
Wait until the build process is complete. This will take a while. Go get a snack, watch some TV, or do something else while you wait. Just don't close the window, or you'll have to start the build all over again.
|
||||
|
||||
## Upload Resources
|
||||
|
||||
Next, we're going to upload the resources folder [we created earlier](#setup-resource-directory) to the proper location.
|
||||
|
||||
## Setup the Server
|
||||
|
||||
Now we're going to do the final configur
|
||||
|
||||
## Updating Darkflame Universe
|
||||
|
||||
In the future, updates will be release to DarkflameServer that will include bug fixes and potentially even new features. To update the server, you can run the following commands:
|
||||
|
||||
**TODO: Complete this.**

## Contributing
|
||||
|
||||
This guide is a work in progress and could use your help.
|
||||
* Complete Google Cloud setup instructions.
|
||||
* Rewrite instructions for running pkextractor on the client (should be easy for anyone to follow).
|
||||
* Rewrite instructions for running fdb_to_sqlite to be easier to follow (should be easy for anyone to follow).
|
||||
- Maybe make an executable you can drag and drop the FDB onto?
|
||||
* Rewrite instructions for running the migration queries on the SQLite to be easier to follow (should be easy for anyone to follow).
