[Updated 4/6/2018] Due to
Homebrew/php tap being deprecated at the end of March 2018, and the moving of all PHP formulas to
Homebrew/core, we've reworked our Guide to work with this new tap.
If you have followed this guide in the past with the
Homebrew/php tap, and are looking to upgrade to the new
Homebrew/core approach, then you should first clean-up your current installation by following our new Upgrading Homebrew.
Part 1: macOS 10.13 High Sierra Web Development Environment
This is an updated version of our prior OS X development series. The newly released macOS 10.13 High Sierra and the accompanying updates to Brew require significant changes compared to prior releases, necessitating a thorough revamp in the process. Since macOS 10.12 we now use Homebrew's Apache, rather than the built-in version, but this new appraoch is more flexible and should continue to work on prior OS X versions.
Developing web applications on macOS is a real joy. There are plenty of options for setting up your development environments, including the ever-popular MAMP Pro that provides a nice UI on top of Apache, PHP and MySQL. However, there are times when MAMP Pro has slow downs, or out of date versions, or is simply behaving badly due to its restrictive system of configuration templates and non-standard builds.
It is times like these that people often look for an alternative approach, and luckily there is one, and it is relatively straight-forward to setup.
In this blog post, we will walk you through setting up and configuring Apache 2.4 and multiple PHP versions. In the second blog post in this two-post series, we will cover MySQL, Apache virtual hosts, APC caching, and Xdebug installation.
This guide is intended for experienced web developers. If you are a beginner developer, you will be better served using MAMP or MAMP Pro.
XCode Command Line Tools
If you don't already have XCode installed, it's best to first install the command line tools as these will be used by homebrew:
$ xcode-select --install
This process relies heavily on the macOS package manager called Homebrew. Using the
brew command you can easily add powerful functionality to your mac, but first we have to install it. This is a simple process, but you need to launch your Terminal (
/Applications/Utilities/Terminal) application and then enter:
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Just follow the terminal prompts and enter your password where required. This may take a few minutes, but when complete, a quick way to ensure you have installed
brew correctly, simply type:
$ brew --version Homebrew 1.5.14 Homebrew/homebrew-core (git revision beff; last commit 2018-04-06)
You should probably also run the following command to ensure everything is configured correctly:
$ brew doctor
It will instruct you if you need to correct anything.
The latest macOS 10.13 High Sierra comes with Apache 2.4 pre-installed, however, it is no longer a simple task to use this version with Homebrew because Apple has removed some required scripts in this release. However, the solution is to install Apache 2.4 via Homebrew and then configure it to run on the standard ports (80/443).
If you already have the built-in Apache running, it will need to be shutdown first, and any auto-loading scripts removed. It really doesn't hurt to just run all these commands in order - even if it's a fresh installation:
$ sudo apachectl stop $ sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null
Now we need to install the new version provided by Brew:
$ brew install httpd
Without options, httpd won't need to be built from source, so it installs pretty quickly. Upon completion you should see a message like:
🍺 /usr/local/Cellar/httpd/2.4.33: 1,633 files, 26.4MB
Now we just need to configure things so that our new Apache server is auto-started
$ sudo brew services start httpd
You now have installed Homebrew's Apache, and configured it to auto-start with a privileged account. It should already be running, so you can try to reach your server in a browser by pointing it at
http://localhost:8080, you should see a simple header that says "It works!".
If you get a message that the browser can't connect to the server, first check to ensure the server is up.
$ ps -aef | grep httpd
You should see a few httpd processes if Apache is up and running.
Try to restart Apache with:
$ sudo apachectl -k restart
You can watch the Apache error log in a new Terminal tab/window during a restart to see if anything is invalid or causing a problem:
$ tail -f /usr/local/var/log/httpd/error_log
Apache is controlled via the
apachectl command so some useful commands to use are:
$ sudo apachectl start $ sudo apachectl stop $ sudo apachectl -k restart
-k will force a restart immediately rather than asking politely to restart when apache is good and ready
Now that we have a working web server, we will want to do is make some configuration changes so it works better as a local development server.
In the latest version of Brew, you have to manually set the listen port from the default of
80, so we will need to edit Apache's configuration file.
For simplicity we'll use the built-in TextEditor application to make all our edits. You can launch this from the Terminal by using the
open -e command followed by the path to the file:
$ open -e /usr/local/etc/httpd/httpd.conf
Find the line that says
and change it to
Next we'll configure it to use the to change the document root for Apache. This is the folder where Apache looks to serve file from. By default, the document root is configured as
/usr/local/var/www. As this is a development machine, let's assume we want to change the document root to point to a folder in our own home directory.
Search for the term
DocumentRoot, and you should see the following line:
Change this to point to your user directory where
your_user is the name of your user account:
You also need to change the
<Directory> tag reference right below the DocumentRoot line. This should also be changed to point to your new document root also:
We removed the optional quotes around the directory paths as TextEdit will probably try to convert those to smart-quotes and that will result in a Syntax error when you try to restart Apache. Even if you edit around the quotes and leave them where they are, saving the document may result in their conversion and cause an error.
In that same
<Directory> block you will find an
AllowOverride setting, this should be changed as follows:
# AllowOverride controls what directives may be placed in .htaccess files. # It can be "All", "None", or any combination of the keywords: # AllowOverride FileInfo AuthConfig Limit # AllowOverride All
Also we should now enable mod_rewrite which is commented out by default. Search for
mod_rewrite.so and uncomment the line by removing the leading
LoadModule rewrite_module lib/httpd/modules/mod_rewrite.so
User & Group
Now we have the Apache configuration pointing to a
Sites folder in our home directory. One problem still exists, however. By default, apache runs as the user
daemon and group
daemon. This will cause permission problems when trying to access files in our home directory. About a third of the way down the
httpd.conf file there are two settings to set the
Group Apache will run under. Change these to match your user account (replace
your_user with your real username), with a group of
User your_user Group staff
Apache likes to have a server name in the configuration, but this is disabled by default, so search for:
and replace it with:
Now, you need to create a
Sites folder in the root of your home directory. You can do this in your terminal, or in Finder. In this new
Sites folder create a simple
index.html and put some dummy content in it like:
<h1>My User Web Root</h1>.
$ mkdir ~/Sites $ echo "<h1>My User Web Root</h1>" > ~/Sites/index.html
Restart apache to ensure your configuration changes have taken effect:
$ sudo apachectl -k restart
If you receive an error upon restarting Apache, try removing the quotes around the DocumentRoot and Directory designations we set up earlier.
Pointing your browser to
http://localhost should display your new message. If you have that working, we can move on!
If you have existing PHP installations via Brew, you need to first cleanup your setup with our Upgrading Homebrew guide before continuing with this section.
We will proceed by installing PHP 5.6, PHP 7.0, PHP 7.1 and PHP 7.2 and using a simple script to switch between them as we need. Up until the end of March 2018, all PHP related brews were handled by
Homebrew/php tab, but that has been deprecated, so now we use what's available in the
Homebrew/core package. This should be a better maintained, but is a much less complete, set of packages.
$ brew install firstname.lastname@example.org $ brew install email@example.com $ brew install firstname.lastname@example.org $ brew install email@example.com
The first one will take a little bit of time as it has to install a bunch of brew dependencies. Subsequent PHP versions will install faster.
You no longer have to
unlink each version between installing PHP versions as they are not linked by default
Also, you may have the need to tweak configuration settings of PHP to your needs. A common thing to change is the memory setting, or the
date.timezone configuration. The
php.ini files for each version of PHP are located in the following directories:
/usr/local/etc/php/5.6/php.ini /usr/local/etc/php/7.0/php.ini /usr/local/etc/php/7.1/php.ini /usr/local/etc/php/7.2/php.ini
Let's switch back to the first PHP version now:
$ brew unlink firstname.lastname@example.org && brew link --force --overwrite email@example.com
At this point, I strongly recommend closing ALL your terminal tabs and windows. This will mean opening a new terminal to continue with the next step. This is strongly recommended because some really strange path issues can arise with existing terminals (trust me, I have seen it!).
Quick test that we're in the correct version:
php -v PHP 5.6.35 (cli) (built: Mar 31 2018 20:21:31) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
Apache PHP Setup - Part 1
You have successfully installed your PHP versions, but we need to tell Apache to use them. You will again need to edit the
/usr/local/etc/httpd/httpd.conf file scroll to the bottom of the
If you have been following this guide correctly, the last entry should be your
LoadModule rewrite_module lib/httpd/modules/mod_rewrite.so
Below this add the following
LoadModule php5_module /firstname.lastname@example.org/lib/httpd/modules/libphp5.so #LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so #LoadModule php7_module /firstname.lastname@example.org/lib/httpd/modules/libphp7.so #LoadModule php7_module /email@example.com/lib/httpd/modules/libphp7.so
We can only have one module processing PHP at a time, so for now, so we have left our
firstname.lastname@example.org entry uncommented while all teh others are commented out. This will tell Apache to use PHP 5.6 to handle PHP requests. (We will add the ability to switch PHP versions later).
Also you must set the Directory Indexes for PHP explicitly, so search for this block:
<IfModule dir_module> DirectoryIndex index.html </IfModule>
and replace it with this:
<IfModule dir_module> DirectoryIndex index.php index.html </IfModule> <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch>
Save the file and stop Apache then start again, now that we have installed PHP:
$ sudo apachectl -k stop $ sudo apachectl start
Validating PHP Installation
The best way to test if PHP is installed and running as expected is to make use of phpinfo(). This is not something you want to leave on a production machine, but it's invaluable in a development environment.
Simply create a file called
info.php in your
Sites/ folder you created earlier with this one-liner.
echo "<?php phpinfo();" > ~/Sites/info.php
Point your browser to
http://localhost/info.php and you should see a shiny PHP information page:
If you see a similar phpinfo result, congratulations! You now have Apache and PHP running successfully. You can test the other PHP versions by commenting the
LoadModule ... email@example.com ... entry and uncommenting one of the other ones. Then simply restart apache and reload the same page.
PHP Switcher Script
We hard-coded Apache to use PHP 5.6, but we really want to be able to switch between versions. Luckily, some industrious individuals have already done the hard work for us and written a very handy little PHP switcher script.
We will install the
sphp script into brew's standard
$ curl -L https://gist.githubusercontent.com/rhukster/f4c04f1bf59e0b74e335ee5d186a98e2/raw > /usr/local/bin/sphp $ chmod +x /usr/local/bin/sphp
Check Your Path
Homebrew should have added its preferred
/usr/local/sbin to your path as part of its installation process. Quickly test this by typing:
$ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
If you don't see this, you might need to add these manually to your path. Depending on your shell your using, you may need to add this line to
~/.zshrc. We will assume you are using the default bash shell, so add this line to a your
.profile (create it if it doesn't exist) file at the root of your user directory:
Testing the PHP Switching
After you have completed these steps, you should be able to switch your PHP version by using the command
sphp followed by a two digit value for the PHP version:
$ sphp 7.0
You will probably have to enter your administrator password, and it should give you some feedback:
$ sphp 70 Switching to firstname.lastname@example.org Switching your shell Unlinking /usr/local/Cellaremail@example.com/5.6.35... 47 symlinks removed Unlinking /usr/local/Cellarfirstname.lastname@example.org/7.0.29... 0 symlinks removed Unlinking /usr/local/Cellaremail@example.com/7.1.16... 0 symlinks removed Unlinking /usr/local/Cellar/php/7.2.4... 0 symlinks removed Linking /usr/local/Cellarfirstname.lastname@example.org/7.0.29... 47 symlinks created If you need to have this software first in your PATH instead consider running: echo 'export PATH="/email@example.com/bin:$PATH"' >> ~/.zshrc echo 'export PATH="/firstname.lastname@example.org/sbin:$PATH"' >> ~/.zshrc You will need sudo power from now on Switching your apache conf Password: Restarting apache All done!
Test to see if your Apache is now running PHP 7.0 by again pointing your browser to
http://localhost/info.php. With a little luck, you should see something like this:
Updating PHP and other Brew Packages
Brew makes it super easy to update PHP and the other packages you install. The first step is to update Brew so that it gets a list of available updates:
$ brew update
This will spit out a list of available updates, and any deleted formulas. To upgrade the packages simply type:
$ brew upgrade
You will need to switch to each of your installed PHP versions and run update again to get updates for each PHP version and ensure you are running the version of PHP you intend.
Activating Specific/Latest PHP Versions
Due to the way our PHP linking is set up, only one version of PHP is linked at a time, only the current active version of PHP will be updated to the latest version. You can see the current active version by typing:
$ php -v
And you can see the specific versions of PHP available by typing:
$ brew info email@example.com firstname.lastname@example.org: stable 7.0.29 (bottled) [keg-only] General-purpose scripting language ...
