How to put a java war project (which runs under Tomkat) on the server?

Question

Java

I made a site locally on Intelij IDE, war Maven project with persistence.xml , pom.xml, web.xml and so on. Works for me on a Tomkat server. I have no idea how to put everything on the server. Please write me a brief instruction on what, how and where.

Answer 1

If you mean by "server" what would work on the Internet. That can be done as follows.
There are 2 ways. 1st put on free "Virtual hosting" for example: Heroku, openShift. An example of deploying a Spring application on Heroku .
Another way that I was advised to start learning DevOps is to create a virtual machine, put my application there and configure this machine as a real server (security, ssh, ...)
I know that Amazon WebServices has free plans. Look that way.
How to deploy is in the video. But in short, without going into details, then: Install OS, install JRE, DB, .... (and all other necessary environment) and deploy. Did it for myself. It worked.
