Magento Setup Help

If you've just installed Magento and are having issues, first step is to check some basic things.

You might also want to check the official guide.

Check PHP Version

Acceptable PHP Versions for Magento 2

First up, Magento 2 won't work with some versions.

Here's the current list of accepted versions:

Running Magento 2 Locally=

If you're running this locally, if you're using something like MAMP, check in the settings:

magento-mamp-php-versions.png

If the version showing as installed doesn't match one of the above accepted versions, change it before continuing.

Check Commandline PHP Version

Type: php -v

You should see something like this:

PHP 7.1.12 (cli) (built: Nov 27 2017 15:53:40) ( NTS )

Copyright (c) 1997-2017 The PHP Group

Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies 

   with Zend OPcache v7.1.12, Copyright (c) 1999-2017, by Zend Technologies


First, if you're running Magento locally, and using something like MAMP, check the versions match.

If they don't then time to fix.

Fixing Different PHP Versions in Commandline and MAMP

We want to get the commandline to use MAMP's version.

1. Edit the system settings to tell it to get PHP from the MAMP version:

nano ~/.bash_profile

Add this line, editing the php version to match whatever you have selected in MAMP:

alias phpmamp='/Applications/MAMP/bin/php7.1.12/bin/php'

2. Check where the local system is getting php from:

which php

which should return something like:

/usr/local/bin/php

3. Backup this php, using the path from (2):

sudo mv /usr/local/bin/php /usr/local/bin/php.bak

4. Make an alias to the MAMP PHP version, using the path from (2) and the PHP version from MAMP:

sudo ln -s /Applications/MAMP/bin/php/php7.1.12/bin/php /usr/local/bin/php

5. Check the new version is sticking:

php -v


Make Initial PHP Settings

Magento needs some minimum system resources. PHP by default will have 128MB of memory allocated. We want more!

Find In-use PHP Settings File (php.ini)

Type: php -r 'phpinfo();' | grep 'php.ini'

Should return something like:

/Applications/MAMP/bin/php/php7.1.12/conf/php.ini


Edit PHP Settings for Magento 2

  • These are basic settings for a new test install.
  • If you're running a live site these will be different!

1. Find that file from above and edit in a text editor.

2. Look for these settings and change them if they're different.

Uncomment (remove the semicolon from the start of the line) if needed.

memory_limit = 2G

^ You might be able to deal with 1G, but for things like updating Magento you might need the 2G.

date.timezone = "Asia/Bangkok"

^ Set this to match your local machine (if running local), or the server timezone.

always_populate_raw_post_data = -1

Uncomment this line: zend_extension="...

Add this line near the above line:

opcache.save_comments=1

^ This turns on PHP caching which will make decent improvements to the speed Magento runs at.

Check PHP Version

Finally check the running PHP version:

php -v


Magento Cache

While you're in the commandline, may as well enable Magento Caches:

bin/magento cache:enable

You can selectively enable/disable caches by adding from :

config layout block_html collections db_ddl eav full_page translate config_integration config_integration_api config_webservice
