Every service in Bearsampp listens on a network port. The default ports follow standard conventions, but you can change any of them from the tray menu — useful when another application on your system is already using the same port.

How to change a port

1

Right-click the Bearsampp tray icon

Find the Bearsampp bear icon in the Windows system tray (bottom-right corner of your taskbar) and right-click it.
2

Open the service menu

Hover over the name of the service whose port you want to change — for example, Apache, MySQL, or MariaDB.
3

Click Change port

In the service submenu, click Change port. A dialog box opens showing the current port number.
4

Enter the new port number

Type the new port number in the input field. Port numbers must be between 1 and 65535. Ports below 1024 require Administrator privileges.
5

Click Finish

Click Finish to apply the change. Bearsampp will update the service configuration and restart the service automatically.
Changing a port requires the service to restart. Any active connections to that service will be interrupted briefly while it restarts.

​
Checking whether a port is available

Before assigning a new port, you can verify it is not already in use by another application.
1

Open the service menu

Right-click the tray icon and hover over the service you want to check.
2

Click Check port

In the service submenu, click Check port [number]. Bearsampp will tell you whether the port is free or identify which process is using it.
Use “Check port” before changing to a new port number to avoid a failed restart caused by a port conflict.

​
Port conflict detection

When Bearsampp starts a service, it automatically checks whether the configured port is already in use. If a conflict is detected, Bearsampp will:
  1. Show an error message identifying which process is occupying the port.
  2. Leave the service stopped rather than forcibly taking the port.
To resolve a conflict, either stop the application using that port or change Bearsampp’s service port to a different number.
Windows services such as IIS (Internet Information Services) often occupy port 80 or 443 by default. If Apache fails to start, check whether IIS is running on your system.
