APACHE needs port 80 - MAMP

Question

I want to run MAMP on my Windows 8.1 pc, but when I start the servers, it says:

'APACHE' needs open port '80' which is already being used by another 
service or application. Please reconfigure 'APACHE' to use free port.

Changing the port to something else doesn't help.

Answer 6

Hey On Windows 10 I Ran into the same issue.. I found a way that is a guarantee fix... Go into controlpanel -> system security -> windows firewall -> on the left pane there is advanced settings.. click that. -> then add new inbound rule (on the left pane click inbound... then new rule on the right pane.) -> then follow the wizard as program and select mamp from C:/MAMP I believe. Then you are Golden!! Hope this helps all those out there with the new windows 10.

Answer 7

If you arrived here because you just installed MAMP on a Windows OS (7~10), then Microsoft IIS is the most likely culprit hanging on to port 80.

You can confirm that with the CLI netstat advice by Sergio below and should you find via netstat that a listening service has a process id that maps to NT Kernal & System (ntoskrnl.exe -> cross check via details tab in task manager) then the culprit is IIS.

To Turn off IIS;

Start menu -> Control Panel -> Programs & Features -> Turn Windows Features On or Off -> De-select 'Internet Information Services'.

If you know why IIS is running then you will likely know the application that specifically needs it and you can turn back on when need (take note of the selection chain when turning off) -- otherwise it's unlikely you need IIS on.

Answer 8

I had the same problem with recent windows update. Closing skype did the trick.

Answer 9

I had the same frustating problem. In case you already turned Skype off and the error still appears, just stop the server the MAMP server and close it, then go to the following address in yor MAMP directory: MAMP\\db\\mysql and delete mysql-bin.index, ib_logfile0 and ib_logfile1 files. The MySQL Server should now connect succesfully with the port 80!

Answer 10

Thru some web searches, I discovered that other windows services are know to be using Port 80. In Windows Search (via Windows Start), type 'services', stop one of these services below en test again till it works. Do not forget to restart it later !

• SQL Server Reporting Services
• Web Deployment Agent Service
• BranchCache
• Sync Share Service
• World Wide Web Publishing Service
• Internet Information Server
