WildFly is a powerful, open-source Java application server used for deploying Java-based applications. Nginx can act as a reverse proxy to route traffic to WildFly, improving performance and security. In this guide, we will show you how to install WildFly and set up Nginx as a reverse proxy on Rocky Linux 8. Whether you’re deploying this on a local server or using a , the steps provided will help you get started.<\/p>\n

\n

Step 1: Update Your System<\/h2>\n

Before starting, ensure your Rocky Linux system is up to date by running the following commands:<\/p>\n

sudo dnf update -y<\/code><\/pre>\n
This ensures your system is ready for the WildFly and Nginx installation, whether you are deploying it locally or on a VPS Windows VPS Servers<\/a> platform.<\/p>\n<\/section>\n
\n
Step 2: Install Java<\/h2>\n
WildFly requires Java to run. Install OpenJDK 11, which is supported by WildFly, using this command:<\/p>\n
sudo dnf install java-11-openjdk-devel -y<\/code><\/pre>\n
Verify the installation:<\/p>\n
java -version<\/code><\/pre>\n
This command should return the installed version of Java.<\/p>\n<\/section>\n
\n
Step 3: Download and Install WildFly<\/h2>\n
Download the latest version of WildFly using the following command:<\/p>\n
\r\ncd \/opt\r\nsudo wget https:\/\/github.com\/wildfly\/wildfly\/releases\/download\/26.1.1.Final\/wildfly-26.1.1.Final.tar.gz\r\n            <\/code><\/pre>\n
Extract the downloaded file:<\/p>\n
sudo tar -xvzf wildfly-26.1.1.Final.tar.gz<\/code><\/pre>\n
Move the extracted folder to a more suitable location:<\/p>\n
sudo mv wildfly-26.1.1.Final \/opt\/wildfly<\/code><\/pre>\n<\/section>\n
\n
Step 4: Set Up WildFly as a Service<\/h2>\n
Create a new service file for WildFly to run as a systemd service:<\/p>\n
sudo nano \/etc\/systemd\/system\/wildfly.service<\/code><\/pre>\n
Add the following content to the file:<\/p>\n
\r\n[Unit]\r\nDescription=WildFly Application Server\r\nAfter=network.target\r\n\r\n[Service]\r\nUser=root\r\nExecStart=\/opt\/wildfly\/bin\/standalone.sh -b=0.0.0.0\r\nStandardOutput=null\r\n\r\n[Install]\r\nWantedBy=multi-user.target\r\n            <\/code><\/pre>\n
Save and exit the file.<\/p>\n
Reload systemd to apply the changes:<\/p>\n
sudo systemctl daemon-reload<\/code><\/pre>\n
Start and enable the WildFly service:<\/p>\n
sudo systemctl start wildfly\r\nsudo systemctl enable wildfly<\/code><\/pre>\n<\/section>\n
\n
Step 5: Install and Configure Nginx<\/h2>\n
Install Nginx using the following command:<\/p>\n
sudo dnf install nginx -y<\/code><\/pre>\n
Create a new Nginx configuration file for the reverse proxy:<\/p>\n
sudo nano \/etc\/nginx\/conf.d\/wildfly.conf<\/code><\/pre>\n
Add the following content to the file:<\/p>\n
\r\nserver {\r\n    listen 80;\r\n    server_name your_domain_or_IP;\r\n\r\n    location \/ {\r\n        proxy_pass http:\/\/localhost:8080;\r\n        proxy_set_header Host $host;\r\n        proxy_set_header X-Real-IP $remote_addr;\r\n        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\r\n        proxy_set_header X-Forwarded-Proto $scheme;\r\n    }\r\n}\r\n            <\/code><\/pre>\n
Replace your_domain_or_IP<\/code> with your domain name or server IP address.<\/p>\n
Test the Nginx configuration:<\/p>\n
sudo nginx -t<\/code><\/pre>\n
If the configuration test passes, start and enable Nginx:<\/p>\n
sudo systemctl start nginx\r\nsudo systemctl enable nginx<\/code><\/pre>\n<\/section>\n
\n
Step 6: Allow Firewall Rules<\/h2>\n
Update your firewall to allow HTTP and WildFly connections:<\/p>\n
\r\nsudo firewall-cmd --permanent --add-service=http\r\nsudo firewall-cmd --permanent --add-port=8080\/tcp\r\nsudo firewall-cmd --reload\r\n            <\/code><\/pre>\n<\/section>\n
\n
Step 7: Access the WildFly Application<\/h2>\n
You can now access your WildFly application through Nginx by navigating to:<\/p>\n
http:\/\/your_domain_or_IP<\/code><\/pre>\n
This will serve your WildFly application through Nginx as a reverse proxy.<\/p>\n<\/section>\n
