LAMP Stack

Introduction#

LAMP (Linux Apache MySQL PHP) consists of the Linux operating system as development environment, the Apache HTTP Server as web server, the MySQL relational database management system (RDBMS) as DB(Data Base) system, and the PHP programming language as Server side (Back End) programming language.

LAMP is used as a Open Source stack of technologies solution to web development area. Windows version of this stack is called WAMP(Windows Apache MySQL PHP)

Installing LAMP on Arch Linux

With this line we will install all the necessary packages in one step, and the last update:

pacman -Syu apache php php-apache mariadb

HTTP

Edit

/etc/httpd/conf/httpd.conf

Change ServerAdmin you@example.com as you need.

The folder of the WEB Pages by default is ServerRoot "/etc/httpd". Directory must be set to the same folder, so change the line

<Directory "/etc/httpd">

This folder must have read and execution access, so

chmod o+x /etc/httpd

Change AllowOverride from none (default) to All so .htaccess will works.

Now you need the ~/public_html folder for each user. (to get the root page of each user as https://localhost/~yourusername/. Unremark this line:

Include conf/extra/httpd-userdir.conf

Now as root you need to create the ~/public_html for each user and change the access to (755) of each one.

chmod 755 /home
chmod 755 /home/username
chmod 755 /home/username/public_html

You can comment out this line if you want to use SSL:

LoadModule ssl_module modules/mod_ssl.so

If you need to use virtual domains, uncomment the line:

Include conf/extra/httpd-vhosts.conf

and in /etc/httpd/conf/extra/httpd-vhosts.conf you must to add all the virtual domains. (plus into /etc/hosts if you want to test those virtuals domains)

Edit /etc/httpd/conf/extra/httpd-default.conf and change ServerSignature to Off and ServerToken to Prod for hiding critical data

PHP

Edit: /etc/httpd/conf/httpd.conf

Comment out: LoadModule mpm_event_module modules/mod_mpm_event.so

Uncomment: LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

As last item in the LoadModule list, add LoadModule php7_module modules/libphp7.so

As last item in the include list, add Include conf/extra/php7_module.conf

Edit /etc/php/php.ini

Uncomment extension=mysqli.so and extension=pdo_mysql.so

Change the timezone as you need, for example:

date.timezone = America/Argentina/Buenos_Aires, date.default_latitude = 0.0, date.default_longitude = 0.0

MySQL

Run as root:

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

Now you have the root of the MySQL Server.

Start MySQL daemon:

systemctl enable mysqld
systemctl start mysqld

At last, run:

sh /usr/bin/mysql_secure_installation

That all to get a web server ready to be customized as you need.

Installing LAMP on Ubuntu

Install apache:

sudo apt-get install apache2

Install MySql:

sudo apt-get install mysql-server

Install PHP:

sudo apt-get install php5 libapache2-mod-php5

Restart system:

sudo systemctl restart apache2

Check PHP installation:

 php -r 'echo "\n\nYour PHP installation is working fine.\n\n\n";'

Installing LAMP stack on CentoOS

Install Apache Web Server

First step is to install web server Apache.

sudo yum -y install httpd

Once it is installed, enable (to run on startup) and start Apache web server service.

sudo systemctl enable --now httpd

Point your browser to:

https://localhost

You will see the default Apache web server page.

Install MariaDB Server

Second step is to install MariaDB:

sudo yum -y install mariadb-server

Then start and enable (on startup) the MariaDB server:

sudo systemctl enable --now mariadb

As needed, use mysql_secure_installation to secure your database.

This script will allow you to do the following:

Change the root user’s password
Remove test databases
Disable remote access

Install PHP

sudo yum -y install php php-common

Then restart Apache’s httpd service.

sudo systemctl restart httpd

To test PHP, create a file called index.php in /var/www/html.

Then add the following line to the file:

Then point your browser to:

https://localhost/index.php

You should see information related to your server. If you do not, ensure that php is for sure installed correctly by running the following command:

php --version

If you receive something like:

Then PHP is installed correctly. If this is the case, please ensure that you’ve restarted your web server.
