Jenkins 2.0 requirements

[Ashish Yadav]

As per https://jenkins.io/2.0/,

> Jenkins 2 now requires Servlet 3.1 to run. If you're not using the embedded Winstone-Jetty, make sure your container supports Servlet 3.1 (e.g. Tomcat 8) before upgrading.

> Jenkins 2 no longer supports AJP with the embedded Winstone-Jetty container, so if you're using Jenkins with a reverse proxy, please make sure it uses HTTP before upgrading.

How can I confirm if I meet the above requirements? I am currently running Jenkins LTS v1.642.3 on CentOS v7. It’s the ‘standard’ installation of Jenkins from the yum repository. How do I know if I am running Servlet 3.1 or Winstone-Jetty?

Jenkins ships with Winstone-Jetty, so that won't be a problem. Some people run Jenkins in Tomcat, Websphere, etc., where they need to consider this.

Regarding the second item, check the service configuration file for mentions of 'AJP'. Disable any options you find.
