Configuring worker machines
In this Deployment assistant step, you assign a worker machine to the web server role. The Deployment assistant looks for the unassigned worker machine on your local network, and if it finds that machine, it displays the IP addresses in the list. If a worker machine isn’t detected, you can look up the IP address of the machine. You can deploy the Web Publishing Engine and web server on the designated worker machine.
To assign a worker machine role:
1. From Web Server, choose the IP address of an unassigned worker machine.
The Deployment assistant detects all unassigned worker machines on the local network and shows their IP addresses in the Web Server list. If the address of a worker is not listed, click Rescan. Then check to see whether the worker is listed.
2. If a worker's IP address is still not listed, enter the IP address, and click Lookup.
The IP address you entered is added to the Web Server list if the machine can be contacted and is an available worker. If the Deployment assistant successfully communicates with the web server, the successful message displays.
If the Deployment assistant detected but could not communicate with the web server and displays this message, make sure you have the correct ports open and available. See Ports used by FileMaker Server.
If you cannot locate the server, web publishing will not be available, and you will have to click Back, and select One Machine. You can edit the deployment after FileMaker Server is installed.
3. Click Next to go to the next step.
Click Back to return to the previous step or Cancel to exit the Deployment assistant.
Notes
You will not be able to see your worker machines if the necessary ports of your firewall are not open. See Ports used by FileMaker Server.
If the Deployment assistant fails to detect the web server, check that you have installed and enabled the web server. Also check that the necessary firewall ports are open. Review the instructions provided in FileMaker Server Getting Started Guide on the Start Page.
If you are deploying FileMaker Server components on two machines, install the software on the worker machine first and then the master machine to ensure a smoother deployment process.
If you cannot find the IP addresses for the worker machines on your network, see Ports used by FileMaker Server.
