Deploy springboot application and react application to ubuntu server - spring

Question

I created a simple application, which consists of a reactjs frontend and a spring boot app as backend. It works fine on my local environment; with the react app running on port 3000, and the spring app running on port 9000.
I am trying to host this application in the staging environment. I want to host both the reactjs and spring boot app on a ubuntu server that I have on digitalocean. I have managed to deploy the reactjs frontend using nginx and now I want to deploy the backend using apache2.
I am having difficulty deploying the Spring boot app. I have generated a WAR file.
In my react application I call the backend spring app to serve as the api to the frontend to the browser. I have set up apache app to listen on port 9000 see below:
<VirtualHost *:9000>
ServerName 46.101.34.160
ServerAdmin webmaster#localhost
DocumentRoot
/var/www/html/BackEndBookingAndCollections
</VirtualHost>
My configuration details for the frontend goes as follows in the file;
/etc/nginx/sites-available/FEBookingAndCollections
The contents is the following:
server {
listen 80;
root /var/www/FEBookingAndCollections/build;
listen [::]:80 default_server;
server_name 46.101.34.160;
index index.html index.htm;
location / {
try_files $uri /index.html;
}
location /api/bookings/ {
proxy_pass http://46.101.34.160:9000/api/bookings;
}
}
In google chrome's browser I get the following error:
Failed to load resource: net::ERR_CONNECTION_REFUSED :9000/api/bookings:1

Answer 1

With spring boot, you don't have to use external Tomcat. You can package your app to jar with embedded tomcat. You can find more info here - https://www.baeldung.com/deployable-fat-jar-spring-boot.

Answer 2

You can't deploy war file without a server. Just follow bellow steps
1) install tomcat
2) find tomcat webapps path ( /usr/local/tomcat/webapps )
3) copy your war file to webapps. ( use scp )
4) make sure your war file and tomcat listen on same port. 8080 or 9000
5) proxy your api though apache
