I took the steps below using a clean install of macOS Sierra, so hopefully I have covered everything that you need to do. MacOS Sierra / Xcode is bundled with Apache and PHP, but we won’t be using these as it is an old version of PHP and messing around trying to update it could potentially break something. In this tutorial, I'll be using my Mac running macOS 10.14 ('Mojave'), but the steps are the same for the other versions of Mac OSX and macOS 10.x (update: I've tested this on Catalina and it works there too). Go to Apache Friends and download the correct version of XAMPP. For this tutorial, I'll be using XAMPP 7.3.2 for OSX. PEAR on macOS 10.15 Catalina. MacOS no longer ships with PEAR, but installing it is quite easy. Once that’s done PEAR and PECL work as expected (if you also want to set up and install Apache, PHP and MySQL, check this post ).
If you want to run a server on your macOS Catalina, or you recently updated to Catalina, you might need to re-configure your system, follow the below instructions.
Updates
For macOS Big Sur (11.0.x) setup guide, please check out Setting Up Your Local Web Server on macOS Big Sur 11.0.1 (2020)| MAMP | macOS, Apache, MySQL, PHP
Start the Apache Server
You can start off the built-in Apache server by following the below steps.
Open Terminal from your Application folder or type “Terminal” in the Spotlight Search.
Type sudo apachectl start and press enter.
Open any of your favorite browser.
Type localhost or 127.0.0.1 in the address bar
If Apache server is started, you should see the below:
Create Sites directory
Let’s create a Sites directory under username folder (username is your mac login name) This directory is going to be the document root.
1. Go to Mac HDD > Users > [your account folder]
2. Create folder with the name Sites. When the folder is created, it will generate a folder with compass image on the folder.
Create username.conf file
To be able to recognize the files putting into Sites directory, username.conf needed to be setup. This is going to be your document root.
Type whoami and press enter. Note down the name. (that is your account name / username)
Create a username.conf file based on the account name showed up when you type whoami. e.g. If your username is developer the filename will be developer.conf.
Type cd /etc/apache2/users and press enter.
Type ls and press enter. Check if there is existing username.conf (username is your account name)
If there is an existing username.conf, make a backup copy by typing sudo cp username.conf username.conf.bakup.
Type sudo nano username.conf and press enter. Note: “username” will be your account name. e.g. developer.conf.
Copy and paste the following configuration.
