Follow the instruction of Confluence, I have successfully installed the SSL for my confluence site on: https://wiki.example.com.
Then I need to setup another website on the same VPS (in my case: manager.io) on the same VPS, which runs a plain http over port 8080.
Since tomcat is installed with Confluence, how can I modify the setup of the tomcat in Confluence to enable the SSL connection on port 8080?
