How to Install GlassFish Java Application Server with Nginx Reverse Proxy on AlmaLinux 9
Introduction
GlassFish is an open-source application server project and Nginx is a high-performance web server. This tutorial will guide you through the process of installing GlassFish Java Application Server with Nginx acting as a reverse proxy on AlmaLinux 9.
Prerequisites
Before you begin, ensure you have:
- An AlmaLinux 9 server
- Root or sudo access to the server
- Basic knowledge of Linux command line
Step 1: Install Java Development Kit (JDK)
GlassFish requires Java to be installed on your system. Install OpenJDK 11:
sudo dnf install java-11-openjdk-devel -y
Step 2: Download and Install GlassFish
Download and extract the GlassFish archive:
cd /tmp
wget https://download.oracle.com/glassfish/5.1.1/glassfish-5.1.1.zip
sudo unzip glassfish-5.1.1.zip -d /opt
Step 3: Start GlassFish
Start the GlassFish domain:
sudo /opt/glassfish5/bin/asadmin start-domain
Step 4: Install and Configure Nginx
Install Nginx:
sudo dnf install nginx -y
Create a new server block configuration file for GlassFish:
sudo nano /etc/nginx/conf.d/glassfish.conf
Add the following content:
server {
listen 80;
server_name your_domain.com;
location / {
proxy_pass http://localhost:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
Test Nginx configuration for syntax errors:
sudo nginx -t
If the test is successful, reload Nginx to apply the changes:
sudo systemctl reload nginx
Step 5: Access GlassFish via Nginx
Open your web browser and navigate to http://your_domain.com. You should see the GlassFish default landing page, indicating that Nginx is successfully acting as a reverse proxy for GlassFish.
Conclusion
Congratulations! You have successfully installed GlassFish Java Application Server with Nginx acting as a reverse proxy on AlmaLinux 9. You can now deploy your Java applications and access them via Nginx.
