How to install (Localhost on your computer) (windows Xampp)

1. Download and Install XAMPP.
2. Clone this github repo into your xampp/htdocs directory.
3. Open XAMPP's control panel and start Apache and MySQL.
4. Click on Admin for MySQL and create a new database, name it whatever you want but remember it!
5. Go to privileges and add a user account, give it any user name, select localhost and create a password. Ensure SSL is enabled.
6. Now go into your preferred web browser and type in localhost/etaki3d, and an admin panel should open up.

• Contents of htdocs in the repository should form the landing page, ensure that the rest of the repository is extracted to the appropraite sub-directory, in this case (/etaki3d).

7. Enter in the name of your created database name along with your username and password.
8. Add yourself as a user, with your own email address, name and password.

Setup without XAMPP using PHP Server [MAC/Linux]

1. Once this github repo is cloned, go to config/database.php

2. Change this line 'default' => 'pgsql', [Available options pgsql, sqlite, sqlsrv, mysql]

3. Create a database

4. Fire up the terminal in the root directory and run the following

   php -S localhost:port [e.g. php -S localhost:9000]

5. Go to localhost:9000/install-db if running for the first time

6. Use the database and auth details used in the previous steps

7. Everything should be installed within a minute

Congratulations, you have successfully installed Eta-Ki!

If you get an error 404

If you encounter a 404 Not Found error, please make sure you enabled the Apache2 mod_rewrite module:

sudo a2enmod rewrite

And then restart Apache2:

sudo service apache2 restart

Configure mod_rewrite by editing one of the following files:

sudo nano /etc/apache2/sites-enabled/000-default.conf

or

sudo nano /var/www/html/.htaccess

and add the following lines:

<Directory /var/www/html>
AllowOverride All
Order allow,deny
allow from all
</Directory>

Recommended configuration

• Go to XAMPP Control Panel and click on config for Apache -> php.ini.
  • Find the memory limit and change it to 512M.
  • Add a max post file size and max upload file size and make them both each 1000M.

Getting started

Let's create our first scene that will display some moving, 3d text.

1. Go to 'Themes' and install the interactive-theme.
2. Add a new space and call it whatever you want.
3. Add as many messages as you want, and press preview!
4. You should now see your text appearing and moving away from you, in this mode you can put on any VR headset and experience this.

Themes

• Themes are installable apps that you can use to visualise, interact and display your VR / 3D content.
• We have provided you with a few to start off with, and we will continue to create themes so make sure to keep this github repo up to date!

Develop and deploy using Docker

In this project, We have defined four docker containers and we use docker-compose to run multi-container Docker applications:

• php
• apache
• postgres
• phppgadmin

A .env file has been created to maintain the global configuration. Please modify it accordingly when running the system in local or production. The individule Dockerfile for php and apache are in /container folder. Please be noted that the database HOST should use db (according to the service name of the DB in docker-compose config file) instead of localhost.

Up and run

Inside etaki3d/, execute:

docker-compose up --build

Stop

Inside etaki3d/, execute:

docker-compose down

Prune created docker resources

Below execution would prune the created docker containers, images, networks

docker system prune
docker system prune -a

If you are sure you want prune the docker volume (CAUTION: it contains the DB data), do this:

docker volume ls
docker volume remove <volume ID>

List containers

1.Running containers Use docker container ls or docker ps

2.Not running containers

Use docker container ls -a or docker ps -a

Sample output of docker-compose up --build

docker-compose up --build
