This comprehensive Linux guide expects that you run the following commands as root user but if you decide to run the commands as a different user then ensure that the user has sudo access and that you precede each of the privileged commands with sudo

The Apache web server is currently the most popular web server in the world, which makes it a great choice for hosting a website. A FAMP stack, which is similar to a LAMP stack on Linux, is a group of open source software that is typically installed together to enable a FreeBSD server to host dynamic websites and web apps. FAMP is an acronym that stands for FreeBSD, Apache, MySQL, and PHP.

Installing Apache

You an easily install Apache from FreeBSD package manager.
A package manager allows us to install most of the software easily from a repository maintained by FreeBSD.

To install Apache us the following command

pkg install apache24

Press y when the confirmation prompt appears

To enable Apache as a service use the following command

sysrc apache24_enable=yes

Starting Apache

Start the Apache service using

service apache24 start

To check that Apache service is running, use

service apache24 status
apache24 is running as pid 20815.

Verification

You can also verify by using the following command in a web browser which will open default FreeBSD Apache web page, which is there for testing purposes. You’ll see: It Works!, which indicates that your web server is correctly installed.

http://your_server_IP_address/

Finding Your Server’s Public IP Address

The universal way to find the ip address is to use ifconfig command as following

ifconfig vtnet0 | grep "inet " | awk '{ print $2; exit }'

Another command like curl can also be used, it would contact an outside party, like icanhazip, to tell you how it sees your server. This is done by asking a specific server what your IP address is: 

curl http://icanhazip.com

Install MySQL

The MySQL server is used to organize and provide access to databases where our server can store information. To install mySQL use the following command

pkg install mysql80-server

Press y when the confirmation prompt appears

Enabling MySQL As A service

Use the following command to add mysql_enable="YES" to the /etc/rc.conf file.

sysrc mysql_enable=yes

Starting MySQL Server

To start the MySQL server use the following command

service mysql-server start

Now the MySQL is running so you will simply have to run the security script as following

mysql_secure_installation

A prompt will appear asking for root password so you will keep it blank by pressing Return. After that a a prompt will appear asking you to set a root password

Enter current password for root (enter for none): [RETURN]
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorization.

Set root password? [Y/n] Y
New password: yuranypassword1234
Re-enter new password: yuranypassword1234
Password updated successfully!

For rest of the questions press the Return key to set values as default values

At this point your database system is setup and you can move on to install PHP.

Installing PHP

This is the component that will process code and display dynamic content.
It can run scripts, connect to MySQL databases to get information, and hand the processed content over to the web server to display. To install it use the following command

pkg install php73 php73-mysqli mod_php73

Press the key y at the confirmation prompt

Now copy the sample PHP configuration file into place with this command: 

cp /usr/local/etc/php.ini-production /usr/local/etc/php.ini

Regenerating The System Cache Information

rehash

Before using PHP, you must configure it to work with Apache

Install PHP Modules

To enhance the functionality you will install the PHP module for this use the following command

pkg search php73
php73-7.3.5                    PHP Scripting Language
php73-aphpbreakdown-2.2.2      Code-Analyzer for PHP for Compatibility Check-UP
php73-aphpunit-1.8             Testing framework for unit tests
php73-bcmath-7.3.5             The bcmath shared extension for php
php73-brotli-0.6.2             Brotli extension for PHP
php73-bsdconv-11.5.0           PHP wrapper for bsdconv
php73-bz2-7.3.5                The bz2 shared extension for php
php73-calendar-7.3.5           The calendar shared extension for php
php73-composer-1.8.4           Dependency Manager for PHP
php73-ctype-7.3.5              The ctype shared extension for php
php73-curl-7.3.5               The curl shared extension for php
php73-dba-7.3.5                The dba shared extension for php
php73-deployer-6.4.3           Deployment tool for PHP
php73-dom-7.3.5                The dom shared extension for php
…

You can get description of the package by typing following command

pkg search -f package_name

Along with the information you will get something like this

php56-calendar-5.6.3
Name           : php56-calendar
Version        : 5.6.3
...
Comment        : The calendar shared extension for php
...

If you decide that you would like to install a package, you can do so by using the pkg install command. For example if I want to install calender, i would use:

pkg install php73-calendar

Configure Apache To Use PHP Module

Open the Apache configuration file by using text editor such as:

nano /usr/local/etc/apache24/Includes/php.conf

Now you will have to add following lines

/usr/local/etc/apache24/Includes/php.conf 
        SetHandler application/x-httpd-php
    
    
        SetHandler application/x-httpd-php-source

Now restart Apache by using following command

sudo service apache24 restart

Check that Apache service is running in good condition use the following command:

apachectl configtest
Performing sanity check on apache24 configuration:
Syntax OK
