If you want to to start Mingle on a port other than 8080, you need to modify the mingle.properties file. Depending on the version of Mingle you are using, the location of your mingle.properties file will differ

With Mingle 2.3.1 or earlier

1. Open the <mingle install dir>/MingleServer.vmoptions file and check the path of the data dir (this is the value of the -Dmingle.dataDir property)
2. Locate the mingle.properties file located in that directory

With Mingle 3.0 or later

1. Open the <mingle install dir>/MingleServer.vmoptions file and check the path of the config dir (this is the value of the -Dmingle.configDir property)
2. Locate the mingle.properties file located in that directory

Once you locate the mingle.properties file

1. Stop the Mingle service
2. Edit the value of the -Dmingle.port property in the mingle.properties file to be the new port you wish to run Mingle on
3. Save the file
4. Restart the Mingle service
