When starting out hosting Barracuda RMM, it is customary to begin with two application servers at a minimum. This allows you to balance the load between the servers as you on-board more VARs with Service Centers.
Adding application servers after the first one is installed is very simple. Perform the install following the exact same procedure you followed for the first one. Then, make sure the IP address of the new application server is added to the load-balancer.
Firewall rules required for multiple application servers
The MW installer doesn’t create the firewall rules that are required for multiple application server configurations. As a result, the creation of a new VAR may fail when installed on multiple application servers with certain firewall rules in place.
To ensure successful VAR creation, add the following rules to Windows Firewall on each application server you want to use:
- %SystemRoot%\System32\inetsrv\w3wp.exe
- %ProgramFiles% (x86)\Level Platforms\Service Center\Bin\SCMonitor.exe
- %ProgramFiles% (x86)\Level Platforms\Service Center\Bin\SCWorker.exe
To Add Rules to Windows Firewall
- In Windows, click Start > Control Panel.
- Click Windows Firewall.
- Click Advanced Settings.
- Click Inbound Rules.
- Click New Rule.
- Click Program.
- Click the This Program Path button and type the following:
%SystemRoot%\System32\inetsrv\w3wp.exe
- Click Next.
- In the Action step, click Next.
- In the Profile step, click Next.
- In the Name step, type a name for the rule, then click Finish.
- Repeat steps 3 to 11 twice, typing the following paths in step 7:
%ProgramFiles% (x86)\Level Platforms\Service Center\Bin\SCMonitor.exe
%ProgramFiles% (x86)\Level Platforms\Service Center\Bin\SCWorker.exe
- Repeat this procedure for each application server you want to use in your installation.
