Setting up LAMP Stack using shell scripting

In this article, we are using a shell script for installing LAMP on Debian OS.

About LAMP

The shortened form stands for Linux, Apache, MySQL, and PHP that is used to set up web servers. The words most often used to describe LAMP are stable, simple, and powerful. It is considered as a stack is on the ground that each level infers off it's base layer. In the Working framework, Linux, is the base layer. At that point Apache, the web server sits on the operating system, and then database stores all the data served by the web server, and PHP or any other P* scripting language is utilized to drive and show all the information, and consider client connection.

Manually installing lamp on all servers can be repetitive and time consuming. Therefore, we have written a script that installs LAMP which configures the necessary permissions and then, starts the web server.

The basic script for LAMP Stack is:

#!/bin/bash

echo -e "\n\nUpdating Apt Packages and upgrading latest patches\n"
sudo apt-get update -y && sudo apt-get upgrade -y

echo -e "\n\nInstalling Apache2 Web server\n"
sudo apt-get install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert -y

echo -e "\n\nInstalling PHP & Requirements\n"
sudo apt-get install libapache2-mod-php7.0 php7.0 php7.0-common php7.0-curl php7.0-dev php7.0-gd php-pear php7.0-mcrypt php7.0-mysql -y

echo -e "\n\nInstalling MySQL\n"
sudo apt-get install mysql-server mysql-client -y

echo -e "\n\nPermissions for /var/www\n"
sudo chown -R www-data:www-data /var/www
echo -e "\n\n Permissions have been set\n"

echo -e "\n\nEnabling Modules\n"
sudo a2enmod rewrite
sudo phpenmod mcrypt

echo -e "\n\nRestarting Apache\n"
sudo service apache2 restart

echo -e "\n\nLAMP Installation Completed"

exit 0

What this script does:

1. Updates the packages.
2. Install Apache web server
3. Install PHP and requirements
4. Install MySQL
5. Setting Permissions
6. Enabling Modules

STEP 1: Create file for script

sudo gedit lamp.sh

In the above command gedit is used to create file. Filename format should be <filename.sh> .

STEP 2: Update Apt Packages and upgrade latest patches

sudo apt-get update -y && sudo apt-get upgrade -y

By running the above command it will update and upgrade the apt-get packages to their current versions in your system.

ps aux | grep -i apt

NOTE: Use above command, if code shows an error while execution.

STEP 3: Install Apache2 Web server

sudo apt-get install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert -y

The above command is used to install the Apache web server on the linux which is acting as the base layer in the LAMP stack.

STEP 4: Install MySQL

sudo apt-get install mysql-server mysql-client -y

The above command is used to install MySQL. It is used for collecting and storing the data as RDBMS.

STEP 5: Install PHP & Requirements

sudo apt-get install libapache2-mod-php7.0 php7.0 php7.0-common php7.0-curl php7.0-dev php7.0-gd php-pear php7.0-mcrypt php7.0-mysql -y

The above command is used to install PHP and requirements. PHP an object oriented scripting language is used to display the data in MySQL.

STEP 6: Setting Permissions

sudo chown -R www-data:www-data /var/www

In the above command

• the chown command changes the ownership to user:group i.e. www-data:www-data in our case.
• -R is used to change the ownership recursively for all files and directories in /var/www.

STEP 7: Enabling Modules

sudo a2enmod rewrite
sudo phpenmod mcrypt

In the above command a2enmod enables apache2 module and phpenmod enables php module.

STEP 8: Restarting Apache

sudo service apache2 restart

The above command is used to restart the apache2 web service.

Conclusion

Now the LAMP installation is completed. LAMP is so extensively and often used to update or host the existing applications, that’s why making it quicker and simple becomes more proficient.
