AWS Elastic Beanstalk is a versatile platform for deploying applications in the cloud, allowing developers to focus on their code while AWS handles load balancing, server configuration, and monitoring. However, deploying Symfony applications presents specific challenges, such as managing friendly routes, JWT key generation , and persistent configurations. This article offers practical solutions based on real-world experiences to overcome these challenges.
Initial Setup of Elastic Beanstalk for Symfony
1. Setting the root directory for Symfony
Elastic Beanstalk configures the web server to point to the singapore telegram data
root directory /var/www/html by default. However, Symfony applications require the server to point to the public/ subdirectory , which results in 404 errors when the required files are not found.
Solution: Nginx Configuration Create or modify the .platform/nginx/conf.d/elasticbeanstalk/01-rewrite.conf file to properly redirect requests to the public/ directory :
location / {
root /var/www/html/public; # Define the public directory as root
try_files $uri /index.php$is_args$args;
}
2. Configuration persistence across deployments
Elastic Beanstalk deployments replace EC2 instances, eliminating any manual changes. To ensure that the configuration persists:
Include the .platform/nginx/conf.d/elasticbeanstalk/01-rewrite.conf file in your repository.
Check that it is not listed in .gitignore and push it to version control: git add .platform/nginx/conf.d/elasticbeanstalk/01-rewrite.conf
git commit -m "Add Nginx configuration for redirection to public/ directory"
3. Configuration validation
After performing a deployment, verify that the Nginx server is using the correct directory:
sudo cat /etc/nginx/conf.d/elasticbeanstalk/01-rewrite.conf
The file should show the line:
root /var/www/html/public;
If it does not appear, make sure the .platform file was correctly included in the deployment.
Result
With this configuration, requests are correctly redirected to the index.php controller inside the public/ directory , resolving 404 errors and ensuring that the Symfony application works correctly.
Common problems and solutions
Problem 1: 404 errors on friendly routes
Symptoms
Symfony friendly routes, such as /order/invoice/{id} , generate 404 errors, while the main page ( / ) loads correctly.
Cause
The default Elastic Beanstalk configuration with Nginx does not redirect requests to the main index.php controller , which is required to process Symfony friendly routes.
Solution
To ensure that Nginx correctly redirects requests:
1. Validate URL Rewriting Configuration Make sure the .platform/nginx/conf.d/elasticbeanstalk/01-rewrite.conf file includes: location / {
root /var/www/html/public; # Public directory
try_files $uri /index.php$is_args$args;
}
2. Persist the configuration Include this file in version control and verify its presence after deployment with:
sudo cat /etc/nginx/conf.d/elasticbeanstalk/01-rewrite.conf
3. Restart Nginx if necessary If the changes are not applied automatically:
sudo service nginx restart
Result
Friendly routes correctly redirect to index.php , eliminating 404 errors.
