In order to understand how a module works we need to find out how basic components like controller, model, block and view interact with each other. If you have already worked with Magento before you should know why we need these structural units and how the module structure was organized in previous Magento versions. (more…)
Magento 2 provides a convenient way to manually install module via composer. But what if you got from the extension provider a zip-file with the basic codebase? In this case, you need to install it to your store, without using Magento Connect manager.
Just follow these simple steps to perform module installation easily:
To install the extensions we should copy it’s code to the required Magento directory:
The left panel shows here the basic listing of the zip-file with a module.
The right panel — Magento 2 codebase.
Current zip-file contains User_Guide.pdf file and the Install directory. Basically, the Install folder content should be copied to the app/code/ directory.
After that, we can use 2 different methods to initialize the module in a store.
This method requires Cron tasks set up and proper running. In case it has not performed yet — do it. You will need it further, not only for extensions installation.
So if Cron is set up correctly, just follow the path in admin panel to initialize the module:
System/ Web Setup Wizard/ Component Manager
Here you can enable all available modules.
In case Magento is set up properly you’ll see the notification that all of the systems run correctly.
Further, before you enable the module, Backup creation will be proposed.
And finally we will see the following screen:
The module has been enabled. And now we can switch back to the module list and enable (install) the next one.
Method #2, in my opinion, is more acceptable for website administrators. This method requires access to the server bash shell. Magento Cli provides a large number of useful console commands to manage the store. And you can get the list of these commands by running: php bin/magento.
But now we need to use only one:
php bin/magento setup:upgrade
This command checks all of the modules and launches schema installation or updating process (if necessary). So you just need one command to perform updating and installation of all modules.
