Setting Up A Lamp Stack On Centos For Web Development

Setting Up a LAMP Stack on CentOS for Web Development

A LAMP stack is a software bundle that combines Linux, Apache, MariaDB (MySQL), and PHP into a comprehensive platform for developing and hosting dynamic web applications. CentOS is a free and open-source Linux distribution that is a popular choice for hosting web servers.

Prerequisites:

• A CentOS 7 or later server
• Root access or a user with sudo privileges

Step 1: Install the LAMP Stack

sudo yum install httpd mariadb-server mariadb php php-mysql

Step 2: Start and Enable Services

sudo systemctl start httpd
sudo systemctl enable httpd
sudo systemctl start mariadb
sudo systemctl enable mariadb

Step 3: Create a MySQL Database and User

sudo mysql -u root -p
CREATE DATABASE my_database;
GRANT ALL PRIVILEGES ON my_database.* TO my_user@localhost IDENTIFIED BY 'my_password';
FLUSH PRIVILEGES;

Step 4: Configure PHP

Edit the PHP configuration file:

sudo vi /etc/php.ini

Update the following settings:

memory_limit = 128M
upload_max_filesize = 2M
post_max_size = 8M

Step 5: Test the Installation

Create a PHP file called info.php in the document root directory (/var/www/html):

<?php
phpinfo();
?>

Access the file in your browser at http://your_server_ip/info.php. It should display information about the PHP installation.

Step 6: Install Composer (Optional)

Composer is a package manager for PHP projects. It helps you manage dependencies and install libraries:

sudo curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Step 7: Secure Your Server

To improve the security of your web server, consider implementing the following measures:

• Enable an HTTPS certificate
• Install a web application firewall (WAF)
• Configure SELinux to enforce security policies## Setting Up A Lamp Stack On Centos For Web Development
