Fedora 42 serves as an excellent hosting platform for OpenEMR due to its cutting-edge package management system, robust security features, and strong community support. The distribution’s emphasis on innovation and stability makes it ideal for healthcare applications that require both reliability and modern functionality. This comprehensive guide will walk you through every step of the installation process, from initial system preparation to final configuration and testing.

Understanding OpenEMR System Requirements

Before beginning the installation process, understanding the system requirements ensures optimal performance and stability for your OpenEMR deployment. The minimum system configuration for running OpenEMR on Fedora 42 includes a 2GHz dual-core processor, 2GB of system memory, and 15GB of unallocated drive space. However, for healthcare environments handling multiple concurrent users and large patient databases, these specifications represent the absolute minimum.

For production environments, consider upgrading to a 2GHz quad-core processor with 4GB of system memory and 20GB of unallocated drive space. Healthcare applications benefit significantly from additional memory and storage capacity, particularly when handling large medical imaging files, extensive patient histories, and concurrent user sessions. The database component of OpenEMR can grow substantially over time, making adequate storage planning crucial for long-term success.

Network considerations play a vital role in OpenEMR deployment. Ensure your server has reliable network connectivity and adequate bandwidth to support remote user access. Security considerations include firewall configuration, SSL certificate implementation, and regular security updates to protect sensitive patient health information.

Pre-Installation System Preparation

System Updates and Package Management

Begin the installation process by updating your Fedora 42 system to ensure all packages are current and security patches are applied. Execute the following command to update the entire system using DNF, Fedora’s advanced package manager:

sudo dnf update -y

This command downloads and installs all available updates for your system packages. The -y flag automatically confirms installation prompts, streamlining the update process. After completing the system update, enable the EPEL (Extra Packages for Enterprise Linux) repository to access additional software packages not included in the standard Fedora repositories:

sudo dnf install epel-release -y

Consider enabling the RPM Fusion repository for additional multimedia codecs and software packages that may prove useful for your OpenEMR deployment. Reboot the system after completing these updates to ensure all kernel and system-level changes take effect properly.

Security Hardening

Configure the firewall to allow necessary web traffic while maintaining security. Fedora 42 uses firewalld as its default firewall management tool. Enable HTTP and HTTPS services in the firewall configuration:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

SELinux (Security-Enhanced Linux) provides additional security layers for web applications like OpenEMR. Verify SELinux is enabled and configured in enforcing mode to protect against potential security vulnerabilities. Create dedicated user accounts with appropriate privileges rather than using root access for routine OpenEMR administration tasks.

Installing Core Dependencies

Apache Web Server Installation

Apache HTTP Server forms the foundation of your OpenEMR web application stack. Install Apache using DNF package manager with the following command:

sudo dnf install httpd -y

After installation completes, start the Apache service and enable it to automatically start during system boot:

sudo systemctl start httpd
sudo systemctl enable httpd

Verify Apache installation by checking the service status and testing web connectivity. The systemctl status httpd command displays current service status and any error messages. Access your server’s IP address through a web browser to confirm Apache is serving the default welcome page successfully.

Configure Apache to use appropriate security settings and optimize performance for healthcare applications. Modify the main Apache configuration file located at /etc/httpd/conf/httpd.conf to adjust settings such as maximum concurrent connections, timeout values, and security headers.

MariaDB Database Server Setup

MariaDB serves as the database backend for OpenEMR, storing patient records, scheduling information, and system configurations. Install MariaDB server and client packages using DNF:

sudo dnf install mariadb-server mariadb -y

Start the MariaDB service and enable automatic startup during system boot:

sudo systemctl start mariadb
sudo systemctl enable mariadb

Secure your MariaDB installation by running the security script that removes test databases, disables remote root login, and sets up proper authentication:

sudo mysql_secure_installation

This interactive script guides you through essential security configurations. Set a strong root password, remove anonymous user accounts, disable remote root login, and remove test databases. These security measures protect your patient data from unauthorized access and potential security breaches.

PHP and Extensions Installation

OpenEMR requires PHP with specific extensions to function properly. Install PHP and the necessary extensions using a single DNF command:

sudo dnf install php php-mysqlnd php-mbstring php-xml php-curl php-gd php-zip php-json php-openssl php-fileinfo php-iconv -y

These extensions provide essential functionality for OpenEMR operations:

• php-mysqlnd: Native MySQL driver for database connectivity
• php-mbstring: Multibyte string handling for international character support
• php-xml: XML processing capabilities for data interchange
• php-curl: HTTP client functionality for external API communications
• php-gd: Graphics library support for image processing

Configure PHP settings for optimal OpenEMR performance by editing the /etc/php.ini file. Increase memory limits, adjust upload file sizes, and configure session settings appropriate for healthcare applications. Restart Apache after making PHP configuration changes to apply the new settings.

Database Configuration for OpenEMR

Creating OpenEMR Database

Access MariaDB as the root user to create the OpenEMR database and dedicated user account. Connect to MariaDB using the root password established during the security installation:

mysql -u root -p

Create a dedicated database for OpenEMR with appropriate character set and collation settings:

CREATE DATABASE openemr CHARACTER SET utf8 COLLATE utf8_general_ci;

Establish a dedicated database user for OpenEMR with limited privileges following the principle of least privilege:

CREATE USER 'openemr_user'@'localhost' IDENTIFIED BY 'secure_password_here';
GRANT ALL PRIVILEGES ON openemr.* TO 'openemr_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace ‘secure_password_here’ with a strong, unique password containing uppercase letters, lowercase letters, numbers, and special characters. Document this password securely as it will be required during the OpenEMR web-based setup process.

Database Optimization

Optimize MariaDB configuration for healthcare applications that require high availability and data integrity. Edit the MariaDB configuration file at /etc/my.cnf.d/server.cnf to adjust buffer sizes, connection limits, and logging settings:

[mysqld]
innodb_buffer_pool_size = 1G
max_connections = 200
innodb_log_file_size = 256M

These settings improve database performance for concurrent users and large datasets typical in healthcare environments. Implement regular backup strategies using mysqldump or MariaDB backup utilities to protect patient data against hardware failures or corruption.

Downloading and Installing OpenEMR

Obtaining OpenEMR Source Files

Download the latest stable version of OpenEMR from the official source repository. Navigate to a temporary directory and use wget to download the OpenEMR archive:

cd /tmp
wget https://sourceforge.net/projects/openemr/files/OpenEMR%20Current/7.0.2/openemr-7.0.2.tar.gz

Verify the download integrity by checking file size and comparing checksums if provided by the OpenEMR project. This verification step ensures the downloaded file hasn’t been corrupted during transfer or tampered with by malicious actors.

File Extraction and Placement

Extract the downloaded archive and move the files to Apache’s document root directory:

tar -xzf openemr-7.0.2.tar.gz
sudo mv openemr-7.0.2 /var/www/html/openemr

Set appropriate file ownership and permissions for the Apache web server to access OpenEMR files:

sudo chown -R apache:apache /var/www/html/openemr
sudo chmod -R 755 /var/www/html/openemr

These permission settings allow the Apache web server to read and execute OpenEMR files while preventing unauthorized access to sensitive configuration files. Certain directories within OpenEMR require write permissions for temporary files and uploads, which will be configured during the web-based setup process.

Apache Virtual Host Configuration

Creating OpenEMR Virtual Host

Configure Apache to serve OpenEMR through a dedicated virtual host configuration. Create a new configuration file in Apache’s configuration directory:

sudo nano /etc/httpd/conf.d/openemr.conf

Add the following virtual host configuration, replacing your_domain_or_IP with your actual domain name or server IP address:

<VirtualHost *:80>
    ServerName your_domain_or_IP
    DocumentRoot /var/www/html/openemr
    
    <Directory /var/www/html/openemr>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    
    ErrorLog /var/log/httpd/openemr-error.log
    CustomLog /var/log/httpd/openemr-access.log combined
</VirtualHost>

This configuration creates a dedicated virtual host for OpenEMR with appropriate directory permissions and logging capabilities. The AllowOverride All directive enables OpenEMR to use .htaccess files for additional configuration settings.

Apache Module Configuration

Enable the mod_rewrite module for URL rewriting functionality required by OpenEMR:

sudo dnf install mod_rewrite -y

Test the Apache configuration syntax to ensure no errors exist in the virtual host configuration:

sudo httpd -t

Restart Apache to apply the new virtual host configuration:

sudo systemctl restart httpd

OpenEMR Web-Based Installation

Initial Setup Access

Open a web browser and navigate to your OpenEMR installation URL. Access the setup wizard by entering the following address, replacing your_server_ip with your actual server IP address or domain name:

http://your_server_ip/openemr

The OpenEMR setup wizard displays an initial welcome screen with system requirements and general installation instructions. Review these requirements carefully to ensure your system meets all necessary specifications before proceeding.

Database Connection Configuration

The setup wizard guides you through database configuration steps. Select “Have setup create the database” option to allow OpenEMR to automatically configure the database structure. Enter the following database connection information:

• Database Name: openemr (created earlier)
• Login Name: openemr_user (database user created earlier)
• Password: The secure password set for openemr_user

The setup wizard tests database connectivity and displays connection status. Successful database connection enables the setup process to continue with schema creation and initial data population.

Administrative User Creation

Configure the initial administrator account for OpenEMR access. This account provides full system administration privileges and should be secured with strong authentication:

• Initial User Login Name: Choose a unique administrative username
• Initial User Password: Create a strong password following healthcare security standards
• Confirm Password: Re-enter the password for verification

Enable two-factor authentication (2FA) for enhanced security if your organization requires additional authentication measures. The setup wizard creates this initial user account with full administrative privileges for system configuration and user management.

Post-Installation Security and Configuration

Security Hardening

Remove the setup.php file immediately after completing installation to prevent unauthorized access to the setup interface:

sudo rm /var/www/html/openemr/setup.php

Configure SSL/TLS certificates to encrypt data transmission between users and the OpenEMR server. Generate SSL certificates using Let’s Encrypt or obtain certificates from a trusted certificate authority for production environments.

Update the Apache virtual host configuration to redirect HTTP traffic to HTTPS and configure SSL settings:

<VirtualHost *:443>
    ServerName your_domain_or_IP
    DocumentRoot /var/www/html/openemr
    
    SSLEngine on
    SSLCertificateFile /path/to/your/certificate.crt
    SSLCertificateKeyFile /path/to/your/private.key
    
    <Directory /var/www/html/openemr>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Performance Optimization

Install and configure PHP-FPM (FastCGI Process Manager) for improved performance with concurrent users:

sudo dnf install php-fpm -y
sudo systemctl start php-fpm
sudo systemctl enable php-fpm

Optimize Apache configuration for healthcare applications by adjusting worker processes, connection limits, and caching settings in the main Apache configuration file. These optimizations improve response times and system reliability under normal healthcare workloads.

Configure database connection pooling and implement caching mechanisms to reduce database load and improve application performance. Monitor system resources regularly to identify performance bottlenecks and optimization opportunities.

Testing and Verification

Functionality Testing

Access the OpenEMR login interface through your web browser to verify successful installation. Use the administrative credentials created during setup to log into the system and verify basic functionality.

Test core OpenEMR features including patient registration, appointment scheduling, and clinical documentation. Create test patient records to verify database connectivity and data persistence. These tests confirm that all system components function correctly and integrate properly.

Verify that file uploads work correctly by testing document attachment functionality. Check that the system properly handles different file types and enforces security restrictions on uploaded content.

Performance Validation

Monitor system resource usage during testing to identify potential performance issues before production deployment. Use tools like htop, iotop, and mysql process monitoring to track CPU, memory, and database performance.

Conduct basic load testing using tools like Apache Bench (ab) to simulate multiple concurrent users and measure response times. Healthcare applications should maintain responsive performance even during peak usage periods.
