The Magento platform comes in two flavors:

• Magento Open Source: The free version, targeting small businesses
• Magento Commerce: The commercial version, targeting small, medium, or enterprise businesses

The difference between the two comes mainly in the form of extra modules that were added to the Commerce version, whereas all the coding concepts and core features remain the same. It goes to say that any knowledge we obtain through following Magento Open Source examples is fully applicable to anyone working on Magento Commerce.

There are several ways that we can obtain source files for Magento Open Source:

• Source file archive (.zip, .tar.gz, .tar.bz2), available at https://magento.com
• Git repository, available at https://github.com/magento/magento2
• Composer repository, available at https://repo.magento.com

Obtaining source files via a CLI from the composer repository is our preferred method. Assuming we are within the empty <PROJECT_DIR> directory, we can kick off this process via the following command:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition .

The dot (.) at the end of this command this tells the composer to pull the files into a current directory.

Once the Composer process is finished, we can start installing Magento. There are two ways we can install Magento:

• Via the Web Setup Wizard: The graphical, browser-based process
• Via the command line: The command-line-based process

Knowing how to install Magento via the command line is an essential skill in day-to-day development, as the majority of development requires the developer to tackle various bin/magento commands—not to mention the command line approach is somewhat faster and easily scripted.

Let's install Magento with the built-in php bin/magento setup:install command and a few of the required installation options as follows:

php bin/magento setup:install \
--db-host="/Applications/MAMP/tmp/mysql/mysql.sock" \ 
--db-name=magelicious \
--db-user=root 
--db-password=root \
--admin-firstname=John \
--admin-lastname=Doe \
--admin-email=john@magelicious.loc \
--admin-user=john \
--admin-password=jrdJ%0i9a69n

After the preceding command has been executed, we should begin to see console progress, starting with something like the following:

Starting Magento installation:
File permissions check...
[Progress: 1 / 513]
Required extensions check...
[Progress: 2 / 513]
Enabling Maintenance Mode...
[Progress: 3 / 513]
Installing deployment configuration...
[Progress: 4 / 513]
Installing database schema:
Schema creation/updates:
Module 'Magento_Store':
[Progress: 5 / 513]

While it might take up to a few minutes, a successful installation should end with a message that's similar to the following:

[Progress: 508 / 513]
Installing admin user...
[Progress: 509 / 513]
Caches clearing:
Cache cleared successfully
[Progress: 510 / 513]
Disabling Maintenance Mode:
[Progress: 511 / 513]
Post installation file permissions check...
For security, remove write permissions from these directories: '/Users/branko/Projects/magelicious/app/etc'
[Progress: 512 / 513]
Write installation date...
[Progress: 513 / 513]
[SUCCESS]: Magento installation complete.
[SUCCESS]: Magento Admin URI: /admin_mxq00c
Nothing to import.

Right after installation, our first step should be to set Magento to developer mode by using the following command:

php bin/magento deploy:mode:set developer

We will take a closer look at Magento modes soon; for now, this is to be taken as is.

If all went well during the Magento installation, we should be able to open the storefront and admin in our browser.
