First, check permissions:
- Ensure that both the user installing Tableau Server and the Run As User have the required permissions to install in the installation directory. For more information, see Required Run As User Account Settings.
- Ensure that Tableau files and folders do not have the "Read-Only" attribute selected. For more information, see File and Folder Permissions at Microsoft TechNet.
- Ensure that the 'Local Service' account has adequate permissions for the root of the drive where Tableau Server is installed.
Resetting Coordination Service (Zookeeper)
If Zookeeper does not start correctly, an error similar to the following will appear in the logs:
Note: Before running the above command, archive your logs. This command will clean up all the log files. For more information, see Work with log files.
Ensure that necessary ports are openEnsure that ports needed by Tableau Server are open.
Checking for Available Ports
Tableau Server checks for available ports for its processes during install and startup.
Checking a range of 1 port(s) for pgsql.port, default 8060.
Checking a range of 1 port(s) for worker0.vizqlserver.port, default 9100.
Init: finished configuring ports after initial config created
If a default port is not available for binding, that information will be outputted to the log.
Opening Ports During Install
During install, Tableau Server opens ports in the Windows Firewall at the SUBNET scope. This is why we recommend that all computers in a Tableau Server cluster be on the same IP subnet.
- Computers connecting from outside the IP subnet will not be allowed to connect, according to the default firewall rules. If you have computers in the cluster on different IP subnets, firewall rules must be set manually.
- Tableau Server does not attempt to open ports in any other firewalls besides Windows Firewall.
Using telnet to check portsTelnet Client is a Microsoft program that can be installed in most Windows Server environments. For more information, see Install Telnet Client at Microsoft Technet. The specific ports Tableau Server uses by default are listed here: Tableau Server Ports.
check that the primary Tableau Server node can communicate with a worker node to complete a worker install using port 3730, you would do the following test from the Primary:
If worker was added using IP address:
telnet <workerIP> 3730
If worker was added using machine name:
telnet <worker-machine-name> 3730
To ensure the worker can reach the primary's Tableau Administrative process:
telnet <primary-machine-name> 8755
To check if a worker can communicate with itself on a port, you would use localhost or 127.0.0.1 from the worker machine:
telnet localhost <port>
If the telnet test is unsuccessful, you will see an error like the following:
Ensure that any proxy, firewall, or antivirus is configured to allow Tableau Server communication over the necessary ports. For more information, see Configuring Proxies for Tableau Server and Improving Performance Using Antivirus Exclusions.
