Deploying gradle spring application on a 1and1 cloud server - spring

Question

I have an apache/2.4.18 ubuntu server and I want to host my spring application on it. I generated a JAR file and can run it on the server. It starts an embedded tomcat server on port 8090.
However when i navigate to 'my-site-ip:8090' the connection times out.
I have zero experience deploying web applications so any help would be appreciated.
I've created a TCP rule for port 8090 and still no joy.
The solution was adding a proxy to the Myapp.conf file as below:
ProxyRequests off
ProxyPreserveHost On
ProxyPass / http://localhost:8090/
ProxyPassReverse / http://localhost:8090/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Answer 1

It´s very hard to explain all the steps in one answer but you can follow these steps to get into the full configuration by your own. I did the same on my 1&1 cloud server.
First of all you need root access to your server.
Normally, on your server the port 80 and 443 should already be open. Else you can define that in the 1&1 Admin Portal. If your Server already has the apache configuration you should be able to see the apache site if you go to your server address. You can find details and the full setup if you dont have an apache installed for this step here:

The second step would be to configure a virtual host on your apache webserver.
This is cool because you can define multiple domains and there applications on your server. So http://yourServer.com(port 80 or 443 from extern) goes to yourApp1. (port 8090 from intern).
In this step you will tell apache if your enter your url to go to your app with port 8090

The last step would be to install your spring-boot app as a service on your machine. The docs of Spring describes it very well.
Installation as an init.d Service
If you install the app as a service you are able to start and stop the app with the service command.
service myapp start
And dont forget to add the plugin for maven or gradle to your pom.xml. This is necessary to run the app as a service.
If you follow these Steps you should be able to reach you app without specify a port and be ready to go with your app in production if necessary.

Answer 2

The best approach for this would be to use the apache proxy. This should get it done.
