Port Assignment

There are two ways to specify ports for processes: during installation or after installation.We recommend configuring port assignment during the installation process as described here.You can control what ports are used in a variety of ways.

You can assign ports either in a configuration file, when the processes are first installed, or after installation, using a TSM command.

Only ports assigned at process installation are preserved if you export your Tableau Server configuration.

As a general best practice you should not restrict the range too tightly because port assignment is done by selecting random ports within the range, and if you do not allow a large enough range, selection may fail to find an available port.

To limit the range from which available ports are chosen to those between 83, your configuration file would include an entry similar to this: If you need more control of port assignment than you can get through a combination of restricting port range and individually assigning ports, you can disable dynamic port mapping at initial server configuration.

For more information, see Ports that are not dynamically mapped, below.

Note: This operation includes steps that you may need to perform using the TSM command line.With dynamic port assignment in place, you can still choose to assign ports for certain processes manually.This approach enables you to assign specific ports to specific processes, while leaving the others to be mapped dynamically.You can control which ports are used by changing the range of ports available to the dynamic assignment process.Doing this leaves dynamic port assignment in place but restricts the ports that can be chosen. If you do not want the ports to have dynamic membership, you can add them statically.This eliminates the need to explicitly exclude the ports that you do not want to participate in a particular Layer 3 VLAN.By default, the initial node runs the License service.If you change port assignments and you are running a local firewall, see Local firewall configuration.You need to do this at installation, by specifying a minimum and maximum port for the range in your configuration file.Note: The minimum allowable size of your port range will depend on your server installation and how many services or processes you are running.
