Another Mac Setup
Feb 15, 2014
I am not a command line expert. Really, the only time I use the command line is for Drush and Git. I used to dread the initial setup, something always was different than the myriad of blogs suggested. This time is was different. Here is my story, it might help others who are faced with the same endeavor.
First the easy part, installing Git. Download Xcode from the App Store. Git comes bundled with it and after the download/auto-install of Xcode, Git is available on the command line. Type in:
will get you:
I use MAMP Pro. The pro version makes life easy. You can switch between different php versions, manage virtual hosts and more, all in the MAMP Pro main window. No command line involved.
After you have downloaded and installed MAMP Pro you need to make some adjustments to the PHP and MySQL settings. With MAMP Pro open go to File > Edit Template > PHP > your_php_version. Find the Resource Limits section and adjust the limits to your needs. I always increase the memory limit and the max execution time so my settings end up like this:
;;;;;;;;;;;;;;;;;; ; ; Resource Limits ; ; ;;;;;;;;;;;;;;;;;; max_execution_time = 60 ; Maximum execution time of each script, in seconds max_input_time = 60 ; Maximum amount of time each script may spend parsing request data memory_limit = 512M ; Maximum amount of memory a script may consume (8MB)
Next go to File > Edit Template > MySQL my.cnf. I normally increase the maximum allowed packet size to 100M as recommended on drupal.org.
max_allowed_packet = 100M
That takes care of the internal settings. Now we have to insure that our projects use MAMPs PHP and not the internal Mac version. Test what php version is being used with the which command on the command line. which php will result in /usr/bin/php
That is the internal Mac version. We want to use the MAMP version, in my case I use php5.3.27. We have to provide the path to the MAMP PHP to the system. We do that by adding the path to the .bash_profile file. When you do this install on a new Mac, this file will probably not exist so create one in your home directory. I use TextWrangler for these things as it allows you to see hidden files and .bash_profile is a hidden file as its name starts with a dot. Add this line to the file:
and then save it as .bash_profile into your home directory. Now restart Apache in the MAMP main window. That will reload the .bash_profile file.
will result in:
That is it for MAMP Pro. On to Drush
There are a couple of things that are different from the last time I installed Drush. Drush now lives on GitHub and it requires Composer. The process is fairly well described at these two sources:
For completeness, here is what I did:
In the directory usr/local/bin I installed composer as suggested on the composer home page:
sudo curl -sS https://getcomposer.org/installer | php sudo mv composer.phar /usr/local/bin/composer
then I installed Drush with:
composer global require drush/drush:6.*
This created a directory .composer in my home directory with Drush being in the vendor folder like so:
Yes, that is right, three Drush in a row…
And lastly I used TextWrangler one more time and added the path to the Drush executable to the .bash_profile file so now it looks like this:
One last step:
When I started to use this setup I got memory errors. I used the Drush status command and got this info:
PHP executable : /Applications/MAMP/bin/php/php5.3.27/bin/php PHP configuration : /Applications/MAMP/bin/php/php5.3.27/conf/php.ini PHP OS : Darwin Drush version : 6.2.0
I opened /Applications/MAMP/bin/php/php5.3.27/conf/php.ini and increases the memory limit to 256M and all was well.
Restart Apache one more time in the MAMP Pro main window and you are done.
