Magento is a highly customizable e-commerce platform and content management system that you can use to build online storefronts or web sites for selling merchandise. Magento provides common e-commerce features, such as shopping carts and inventory management, and encourages extensive customization to meet your organization’s specific goals.
Magento 2 Merchant Beta codebase was released on July 15, 2015. This is a significant milestone before the general availability of Magento 2 in Q4 2015.
Before you begin the installation
1. MEMP(Mac OS X + Nginx + MySQL + PHP-FPM) stack should already be installed & configured in your system. And the system should meet the requirements discussed in Magento system requirements.
If MEMP stack is not installed, I would recommend homebrew package manager for installation.
2. Some Assumptions
Magento Dir: ~/Sites/opensource/magento/magento2beta
Virtual Host: magento2beta.dev
Once your MEMP system is ready meeting all the requirements, you are ready to move ahead for the installation.
Installation Steps
1. Create the project folder & clone the magento2 codebase
mkdir ~/Sites/opensource/magento/magento2beta && cd ~/Sites/opensource/magento/magento2beta
git clone [email protected]:magento/magento2.git .

2. Check out the master branch
git checkout master
OR you can directly use the following command while cloning:
git clone -b master https://github.com/magento/magento2.git

Note:
You can clone either the master or develop branch:
- master is more stable
- develop is more recent
Initially, we had an issue installing the sample data with the develop branch, which resulted in the following error:
Fatal error: Call to undefined method Magento\Catalog\Model\Resource\Product\Interceptor::getWriteConnection() in app/code/Magento/SampleData/Module/Catalog/Setup/Product/Gallery.php on line 144

Due to recent changes, you can now use sample data with either the develop branch (more current) or the master branch.
3. File permission
chmod -R 755 ./
4. Update Magento dependencies using Composer
Install Composer if it’s not already installed:
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
Now run Composer to update dependencies:
composer install
This command updates package dependencies and can take a few minutes to complete.

5. Install sample data before Magento installation
– Edit composer.son:
In the first section, add “minimum-stability”: “beta”, before license.
then run the following commands:
composer config repositories.magento composer http://packages.magento.com
composer require magento/sample-data:1.0.0-beta

Note: You can also install sample data after Magento installation
[EDIT]
Magento 2 dev team has an updated version on how to install sample data:
http://devdocs.magento.com/guides/v2.0/install-gde/install/web/install-web-sample-data.html
6: Finally install Magento System
Run the following command in order to install the Magento system:
php bin/magento setup:install --base-url=http://magento2beta.dev/ \
--db-host=localhost \
--db-name=magento2beta \
--db-user=root \
--db-password=root \
--admin-firstname=Raj \
--admin-lastname=KB \
[email protected] \
--admin-user=admin \
--admin-password=pass123 \
--language=en_US \
--currency=USD \
--timezone=America/Chicago \
--sales-order-increment-prefix="ORD
quot; \ --session-save=db \ --use-rewrites=1 \ --use-sample-data \ --cleanup-database

7: Installation Complete!
Now you can explore the frontend and backend.

Have fun with Magento 2!
Magento2’s requirements list Apache 2.2 or 2.4. It also has a nginx sample conf file. Does Magento2 support nginx out of the box? Any issues with using nginx vs. apache? Would be great if we can use nginx with no problems.
Yes it does. I am using it with Magento 2 without any issues. FYI, nginx version of mine is 1.6.2. Though Magento 2 recommends nginx 1.8 (or latest stable version)
I may try firing it up on nginx 1.9.5 w/ HTTP/2 & PHP7 and see what happens.
Good Luck! Please share your results
I may try firing this up on nginx 1.9.5 with HTTP/2 and PHP7 and see what happens.
Thanks for the article. A help article tweeted!
