LEMP stack is a popular set of open-source software that is used to serve dynamic websites and applications. LEMP stands for Linux, Nginx (pronounced “Engine-X”), MariaDB, and PHP. In this guide, we will walk you through how to install and configure the LEMP stack with PHP Opcache, Redis, and secure your server using Let’s Encrypt SSL on Fedora 32. Whether you’re hosting your server on a or another cloud service, this guide will help you set up a powerful web server.<\/p>\n
Before starting, ensure you have the following:<\/p>\n
First, make sure your system is up to date. Run the following commands:<\/p>\n
sudo dnf update -y<\/code><\/pre>\nStep 2: Install Nginx<\/h2>\n
Nginx will serve as the web server for your LEMP stack. Install Nginx with the following command:<\/p>\n
sudo dnf install nginx -y<\/code><\/pre>\nOnce installed, start Nginx and enable it to start on boot:<\/p>\n
sudo systemctl start nginx\r\nsudo systemctl enable nginx<\/code><\/pre>\nStep 3: Install PHP and PHP Extensions<\/h2>\n
Next, install PHP along with necessary extensions, including Opcache for improved performance:<\/p>\n
sudo dnf install php php-fpm php-mysqlnd php-opcache php-xml php-mbstring php-zip php-json php-curl -y<\/code><\/pre>\nConfigure PHP-FPM by editing the following file:<\/p>\n
sudo nano \/etc\/php-fpm.d\/www.conf<\/code><\/pre>\nFind the line that starts with user =<\/code> and group =<\/code> and change it to:<\/p>\nuser = nginx\r\ngroup = nginx<\/code><\/pre>\nSave the file and restart PHP-FPM:<\/p>\n
sudo systemctl restart php-fpm\r\nsudo systemctl enable php-fpm<\/code><\/pre>\nStep 4: Install MariaDB<\/h2>\n
MariaDB is a powerful open-source database management system that will store your website’s data. Install MariaDB by running:<\/p>\n
sudo dnf install mariadb-server -y<\/code><\/pre>\nOnce installed, start and enable MariaDB:<\/p>\n
sudo systemctl start mariadb\r\nsudo systemctl enable mariadb<\/code><\/pre>\nSecure the MariaDB installation by running the security script:<\/p>\n
sudo mysql_secure_installation<\/code><\/pre>\nFollow the on-screen instructions to set a root password and secure your database server.<\/p>\n
Step 5: Install Redis<\/h2>\n
Redis is a powerful in-memory key-value store that can be used to speed up your web applications. Install Redis with the following command:<\/p>\n
sudo dnf install redis -y<\/code><\/pre>\nStart and enable Redis:<\/p>\n
sudo systemctl start redis\r\nsudo systemctl enable redis<\/code><\/pre>\nTo integrate Redis with PHP, install the Redis PHP extension:<\/p>\n
sudo dnf install php-redis -y<\/code><\/pre>\nStep 6: Configure Nginx for PHP<\/h2>\n
Create a new Nginx server block to host your website. For example, create a configuration file for your domain:<\/p>\n
sudo nano \/etc\/nginx\/conf.d\/your-domain.conf<\/code><\/pre>\nAdd the following configuration:<\/p>\n
server {\r\n listen 80;\r\n server_name your-domain.com www.your-domain.com;\r\n\r\n root \/var\/www\/html;\r\n index index.php index.html index.htm;\r\n\r\n location \/ {\r\n try_files $uri $uri\/ =404;\r\n }\r\n\r\n location ~ \\.php$ {\r\n include fastcgi_params;\r\n fastcgi_pass unix:\/run\/php-fpm\/www.sock;\r\n fastcgi_index index.php;\r\n fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;\r\n }\r\n\r\n location ~ \/\\.ht {\r\n deny all;\r\n }\r\n}<\/code><\/pre>\nSave the file and restart Nginx to apply the changes:<\/p>\n
sudo systemctl restart nginx<\/code><\/pre>\nStep 7: Secure Your Website with Let’s Encrypt SSL<\/h2>\n
To secure your website, you can use Let’s Encrypt to obtain a free SSL certificate. First, install Certbot:<\/p>\n
sudo dnf install certbot python3-certbot-nginx -y<\/code><\/pre>\nNext, run the following command to obtain an SSL certificate for your domain:<\/p>\n
sudo certbot --nginx -d your-domain.com -d www.your-domain.com<\/code><\/pre>\nFollow the on-screen instructions to complete the process. Certbot will automatically configure Nginx to use SSL.<\/p>\n
Step 8: Test Your LEMP Stack<\/h2>\n
To test if everything is working, create a simple PHP file in the \/var\/www\/html<\/code> directory:<\/p>\nsudo nano \/var\/www\/html\/info.php<\/code><\/pre>\nAdd the following content to the file:<\/p>\n
<?php phpinfo(); ?><\/code><\/pre>\nSave the file and navigate to http:\/\/your-domain.com\/info.php<\/code> in your web browser. You should see the PHP information page, which indicates that PHP is working correctly with Nginx.<\/p>\nConclusion<\/h2>\n
By following these steps, you have successfully installed the LEMP stack with PHP Opcache, Redis, and Let’s Encrypt SSL on Fedora 32. Whether you are hosting your website on a , Microsoft SQL VPS Windows<\/a>, or another Windows VPSVirtual Private Server Hosting<\/a>, this setup will help you create a fast and secure web application.<\/p>\n
