macOS Update: While these instructions still work, there are new posts for recent versions of macOS, the latest being Install Apache, PHP, and MySQL on macOS Mojave.
I recently upgraded to Mac OS X Yosemite. It seems Mac OS X Yosemite makes my original post on installing Apache, PHP, and MySQL on Mac OS X obsolete. Specifically, Yosemite includes Apache 2.4. This post is a complete update for installing Apache, PHP, and MySQL on Mac OS X Yosemite.
A reminder that Mac OS X runs atop UNIX. So most UNIX software installs easily on Mac OS X. Furthermore, Apache and PHP come packaged with Mac OS X. To create a local web server, all you need to do is enable them and install MySQL.
I am aware of the web server software available for Mac OS X, notably MAMP. These get you started quickly. But they forego the learning experience and, as most developers report, can become difficult to manage.
First, open the Terminal app and switch to the
root user to avoid permission issues while running these commands.
Enable Apache on Mac OS X
Verify It works! by accessing http://localhost
Enable PHP for Apache
First, make a backup of the default Apache configuration. This is good practice and serves as a comparison against future versions of Mac OS X.
Now edit the Apache configuration. Feel free to use TextEdit if you are not familiar with vi.
Uncomment the following line (remove
You can verify PHP is enabled by creating a
phpinfo() page in your
DocumentRoot for Mac OS X Yosemite is
/Library/WebServer/Documents. You can verify this from your Apache configuration.
Now create the
phpinfo() page in your
Verify PHP by accessing http://localhost/phpinfo.php
Install MySQL on Mac OS X
Note: If you are upgrading MySQL you should skip this section and instead read this.
- Download the MySQL DMG for Mac OS X
- Install MySQL
The README suggests creating aliases for
mysqladmin. However there are other commands that are helpful such as
mysqldump. Instead, I updated my path to include
Note: You will need to open a new Terminal window or run the command above for your path to update.
I also run
mysql_secure_installation. While this isn't necessary, it's good practice.
Connect PHP and MySQL
You need to ensure PHP and MySQL can communicate with one another. There are several options to do so. I do the following:
Additional Configuration (optional)
The default configuration for Apache 2.4 on Mac OS X seemed pretty lean. For example, common modules like
mod_rewrite were disabled. You may consider enabling this now to avoid forgetting they are disabled in the future.
I edited my Apache Configuration:
I uncommented the following lines (remove
Note: Previous version of Mac OS X ran Apache 2.2. If you upgraded OS X and previously configured Apache, you may want to read more about upgrading to to Apache 2.4 from Apache 2.2.
If you develop multiple projects and would like each to have a unique url, you can configure Apache VirtualHosts for Mac OS X.
