how to check apache server and php installed or not on mac

 macOS comes with Apache pre-installed, though it may not be enabled by default. You can check its installation and status using the Terminal with the following commands: 

• Check the Apache version: Running the apachectl -v command will display the installed Apache version and build date, which confirms the software is present.
  bash

  apachectl -v
  

• Check if the Apache service is running: Use sudo apachectl status to see the current status of the Apache service. You can also use the ps aux | grep httpd command to list all running processes related to Apache's executable (httpd).
  bash

  sudo apachectl status
  # or
  ps aux | grep httpd
  

• Verify the installation via web browser: If the service is running, open a web browser and navigate to http://localhost. If you see the message "It works!", then Apache is installed and serving web pages correctly.
• Locate the Apache binary: The which command can show the location of the Apache executable in your system's PATH, which is typically /usr/sbin/httpd for the default macOS installation.
  bash

  which httpd
  # or
  whereis httpd
  

   

If these commands do not work, Apache may not be correctly configured or installed on your system. In such cases, you might consider installing it via a package manager like Homebrew. 

To run an Apache and PHP server on a Mac, you can use the built-in server (in older macOS versions), install a fresh version using Homebrew, or use a pre-packaged solution like MAMP. 

Method 1: Using the Built-in Apache (Older macOS)

Older versions of macOS came with Apache pre-installed, though it required manual activation and PHP was removed from the default installation in macOS Monterey. 

• Start Apache: Open the Terminal app (search in Spotlight) and run:
  bash

  sudo apachectl start
  

  You will be prompted for your system password.
• Verify Apache: Open a web browser and navigate to http://localhost/. You should see the message "It works!".
• Enable PHP: If your macOS version has a built-in PHP module, you would typically edit the Apache configuration file using a text editor like nano:
  bash

  sudo nano /etc/apache2/httpd.conf
  

  Inside the editor, find the line that loads the PHP module (e.g., #LoadModule php7_module ... or #LoadModule php_module ...) and remove the # character from the beginning to uncomment it. Save the file (Ctrl+X, then Y, then Enter) and restart Apache:
  bash

  sudo apachectl restart
  

   

Method 2: Using Homebrew (Recommended for Modern macOS)

For the latest macOS versions, installing Apache and PHP via Homebrew is recommended as it provides more control over versions and avoids conflicts with system updates. 

1. Install Homebrew: Follow the instructions on the official Homebrew website to install it.
2. Install Apache and PHP: In the terminal, run:
   bash

   brew install httpd php
   

   This installs both the Apache server (httpd) and the latest stable PHP version.
3. Configure and Start: Follow the post-installation instructions provided by Homebrew in the terminal output to configure and start the services. Configuration files are typically located in /opt/homebrew/etc/httpd/ (on Apple Silicon Macs).
4. Verification: Access http://localhost:8080 (or port 80, depending on your configuration) in a browser to verify Apache is running.
