Get Started with OpenEMR on AWS Express: Easy Installation Guide

Are you looking to set up a robust electronic health record (EHR) system for your medical practice? Look no further! This article will walk you through installing OpenEMR on AWS Express.

Whether you’re a small clinic or a growing healthcare organization, this guide will help you get up and running with a powerful, scalable solution.

AWS Express provides a simplified deployment process for OpenEMR. It’s designed to make the installation accessible to organizations of all sizes, even if you’re not a tech wizard. Plus, you benefit from AWS’s robust infrastructure and security features.

Prerequisites

Before we begin, ensure you have:

1. An AWS account with administrative access
2. AWS CLI installed and configured
3. Basic understanding of AWS services (EC2, RDS, S3, CloudFormation)
4. Familiarity with the Linux command line
5. A registered domain name (for production deployments)

Deployment Architecture

The OpenEMR AWS Express stack creates the following core components:

• EC2 instance running Amazon Linux 2
• RDS MySQL database
• S3 bucket for backups and file storage
• Elastic IP for static addressing
• Security Groups for EC2 and RDS
• IAM role for EC2 instance

Let’s dive into the deployment process.

Detailed Deployment Steps

1. Launching the CloudFormation Stack

While you can use the AWS Console, let’s use the AWS CLI for a more programmatic approach:

aws cloudformation create-stack \
  --stack-name OpenEMR-Express \
  --template-url https://s3.amazonaws.com/openemr-cfn-express/OpenEMR-Express.json \
  --parameters \
    ParameterKey=InstanceType,ParameterValue=t3.medium \
    ParameterKey=KeyPair,ParameterValue=your-key-pair \
    ParameterKey=AdminPassword,ParameterValue=your-admin-password \
    ParameterKey=RDSPassword,ParameterValue=your-rds-password \
    ParameterKey=UseRoute53,ParameterValue=true \
    ParameterKey=RouteHostname,ParameterValue=openemr \
    ParameterKey=RouteDomain,ParameterValue=yourdomain.com \
  --capabilities CAPABILITY_IAM

This command launches the CloudFormation stack with specified parameters. Adjust the values as needed for your deployment.

2. Monitoring Stack Creation

You can monitor the stack creation process using:

aws cloudformation describe-stacks --stack-name OpenEMR-Express --query 'Stacks[0].StackStatus'

Once the status is CREATE_COMPLETE, retrieve the OpenEMR URL:

aws cloudformation describe-stacks --stack-name OpenEMR-Express --query 'Stacks[0].Outputs[?OutputKey==`OpenEMRURL`].OutputValue' --output text

3. Initial Configuration

After accessing the OpenEMR URL, you’ll need to complete the initial setup:

1. Log in with the username admin and the AdminPassword you specified.
2. Navigate to Administration > Globals
3. Configure essential settings like Clinic Name, Default Language, and Time Zone

Advanced Configuration

Customizing PHP Settings

To optimize PHP for OpenEMR, SSH into your EC2 instance and edit the PHP configuration:

sudo vim /etc/php.ini

Adjust these settings for better performance:

memory_limit = 512M
max_execution_time = 300
post_max_size = 30M
upload_max_filesize = 30M

Restart Apache to apply changes:

sudo systemctl restart httpd

Configuring SSL/TLS

For production deployments, securing your OpenEMR instance with SSL/TLS is crucial. AWS Express stack uses Let’s Encrypt for free SSL certificates. To renew or troubleshoot:

sudo certbot renew --dry-run

Database Optimization

Fine-tune your RDS MySQL instance by modifying the parameter group. Key parameters to consider:

• innodb_buffer_pool_size: Set to 70-80% of available RAM
• max_connections: Adjust based on expected concurrent users
• slow_query_log: Enable performance monitoring

You can modify these using the AWS RDS console or AWS CLI.

Security Enhancements

Implementing Multi-Factor Authentication

OpenEMR supports Google Authenticator for MFA. Enable it in the interface:

1. Go to Administration > Globals > Security
2. Set ‘Google Auth Login’ to ‘Yes’
3. Users can then configure MFA in their user settings

Regular Security Audits

Implement regular security audits using AWS Config rules. For example, to ensure your EC2 instance is not publicly accessible:

aws configservice put-config-rule --config-rule '{
    "ConfigRuleName": "ec2-instance-no-public-ip",
    "Description": "Checks whether EC2 instances have public IPs.",
    "Source": {
        "Owner": "AWS",
        "SourceIdentifier": "EC2_INSTANCE_NO_PUBLIC_IP"
    },
    "Scope": {
        "ComplianceResourceTypes": [
            "AWS::EC2::Instance"
        ]
    }
}'

Performance Optimization

Implementing Caching

Improve OpenEMR’s performance by implementing Redis caching. SSH into your EC2 instance and install Redis:

sudo amazon-linux-extras install redis6
sudo systemctl start redis
sudo systemctl enable redis

Then, configure OpenEMR to use Redis by editing /var/www/openemr/sites/default/config.php:

$GLOBALS['redis_server'] = 'localhost';
$GLOBALS['redis_port'] = 6379;
$GLOBALS['cache_user_data'] = 1;
$GLOBALS['cache_session_data'] = 1;

Optimizing MySQL Queries

Identify slow queries using the MySQL slow query log. Connect to your RDS instance and enable it:

SET GLOBAL slow_query_log = 'ON';
SET GLOBAL long_query_time = 2;
SET GLOBAL slow_query_log_file = '/var/log/mysql/mysql-slow.log';

Analyze the log file to identify and optimize problematic queries.

Monitoring and Logging

Setting Up CloudWatch Alarms

Create CloudWatch alarms to monitor critical metrics. For example, to alert on high CPU usage:

aws cloudwatch put-metric-alarm \
    --alarm-name OpenEMR-HighCPUUsage \
    --alarm-description "Alarm when CPU exceeds 70%" \
    --metric-name CPUUtilization \
    --namespace AWS/EC2 \
    --statistic Average \
    --period 300 \
    --threshold 70 \
    --comparison-operator GreaterThanThreshold \
    --dimensions Name=InstanceId,Value=i-1234567890abcdef0 \
    --evaluation-periods 2 \
    --alarm-actions arn:aws:sns:us-east-1:123456789012:OpenEMR-Alerts \
    --unit Percent

Replace the InstanceId and SNS topic ARN with your own values.

Centralized Logging

Implement centralized logging using AWS CloudWatch Logs. Install and configure the CloudWatch Logs agent on your EC2 instance:

sudo yum install -y awslogs
sudo systemctl start awslogsd
sudo systemctl enable awslogsd

Configure /etc/awslogs/awslogs.conf to ship OpenEMR logs:

[/var/www/openemr/sites/default/documents/logs/error_log]
datetime_format = %b %d %H:%M:%S
file = /var/www/openemr/sites/default/documents/logs/error_log
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file
log_group_name = /openemr/error_log

Deploying OpenEMR on AWS Express provides a robust, scalable, and secure platform for electronic health records management. This guide covered advanced deployment techniques, security enhancements, performance optimizations, and monitoring strategies.

By leveraging these practices, you can ensure a high-performing, secure OpenEMR installation capable of meeting the demands of modern healthcare IT.
