How to deploy jar program in nginx

To deploy a JAR program on Nginx, seven steps need to be followed: 1) Install JRE, 2) Install Nginx, 3) Configure Nginx, 4) Deploy JAR, 5) Grant execution permissions, 6) Restart Nginx, 7) Verify deployment.

Nginx deploys JAR programs

Deploying a JAR program to an Nginx server for a Java Web application requires the following steps:

1. Install Java Runtime Environment (JRE)

• Install JRE on the server, which is the software environment required to run Java programs.

2. Install nginx

• Install the Nginx Web Server on the server, which is the software that handles web requests.

3. Configure nginx

• Add the following to the Nginx configuration file to instruct Nginx how to handle JAR files:

 <code>location /myapp { proxy_pass http://localhost:8080; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; }</code>

• Replace localhost:8080 as the actual Java Web application port.

4. Deploy JAR files

• Copy the JAR file to the specified directory of the Nginx Web server, such as /usr/share/nginx/html/myapp/myapp.jar .

5. Grant execution permissions

• Grant JAR file execution permissions so that Nginx can start the application:

 <code>chmod x /usr/share/nginx/html/myapp/myapp.jar</code>

6. Restart Nginx

• Restart Nginx to apply the changed configuration:

 <code>systemctl restart nginx</code>

7. Verify deployment

• Use a web browser to access the application's URL (for example, https://your-domain/myapp). If the application is running normally, the deployment is successful.
