Create a Java Key Store to hold your SSL Certificate. You will need to update location to JDK, alias, and give appropriate path for the keystore location. Make sure it is NOT in the apache-tomcat-flexdeploy folder.
...
The apache-tomcat-flexdeploy folder will be cleaned up with each upgrade, so it is important not to place all supporting files in the flexdeploy home folder or another subfolder instead. This example uses /home/oracle for the location.

Import your SSL certificate. You will need to adjust the JDK location, the keystore name, alias name, and the certificate file name.
...
| Note |

When you are importing the SSL certificate, the certificate alias must be different than the keystore alias. Otherwise |

Edit <FlexDeploy Home>/apache-tomcat-flexdeploy/conf/server.xml. Modify the HTTP connector that is listening on port 80 as follows to listen on some port (not 443). Be sure to adjust keystore file path.

On Unix, privileged ports (less than 1024) cannot be opened by a non-root user. The solution is to forward traffic from 443 to the port used above (8443). As root, update iptable rule to redirect the traffic from 443 to 8443.
