Apache service failing (“BUSY”) when using port 80 [closed]

Answer 1

You can also just change the port the Apache Web Server is using in the httpd.conf file.

In a Windows OS command prompt I use;

netstat -an

to see what services are already running, and what ports they are using, then just pick a port number that's not being used. Much simpler. That's for my Dev environment. On an actual server or in the cloud, I would run the Apache Web Server without conflicts and just shutdown anything else that happens to be using port 80.

Answer 2

For me, it turned out to be that "Web Deployment Agent Service" was taking port 80. As soon as it was disabled apache started right up. I've also come across quite a few saying some of the SQL Server services were blocking it.

EDIT:
Just thought I'd add that the new MSN(Skype) causes this as well, using port 80 by default. It can be changed in the settings:

Tools > Options > Advanced > Connection > Untick "Use Port 80 and 443" > Save

Answer 3

Oh, thank you a thousand times. I've been wrestling all day with getting port 80 free. Tried everything that I found on the chat rooms, forums, including the regex edit above, and still there was:

netstat -ano -p tcp | findstr LISTENING

TCP    0.0.0.0:80             0.0.0.0                  LISTENING       4
TCP    0.0.0.0:445            0.0.0.0                  LISTENING       4  etc.

Now port 80 has disappeared from the display. What a relief!

Answer 4

Several programs can block that port. Candidates are:

• Skype
• Web Deployment Agent Service (can be stopped via Start -> [-> Run] -> services.msc)
• World Wide Web Publishing Service
• IIS (if you have it installed)
• TeamViewer

• VMware (in VMware Workstation go to Edit>>Preferences>>Shared VMs, and Disable Sharing or change the port)

  Web Deployment Agent Service and World Wide Web Publishing Service can be set to manual start to keep them from running. Stop or change these services from an account that has administrator permissions. Skype and TeamViewer can be configured not to use port 80. For Skype Go to Options > Advanced > Connection and un-check "Use port 80 and 443 for incoming connections" For TeamViewer Go to Extra > Options > Advanced and un-check the similar message as above.

EDIT: I made the post a community Wiki, so if people find other programs, they can add them here.

Answer 5

I’m currently beta testing the next version of Windows, Windows 7 and came across a strange issue while trying to get Apache to install and run using the default port, 80.

Running the command ‘netstat -ano’ from the command line revealed that port 80 is being used by PID 4.

Looking up PID 4 using Power Shell and then Task Manager revealed that PID 4 is the NT Kernel!

So Windows 7 by default appears to be using port 80.

After a bit of hunting around the Internet and doing some research of my own I found that the service http.sys was the culprit and all I needed to do was disable it but I could not find this service listed in the Services control panel applet. So what’s the solution?

You have to disable the http.sys service manually via the registry:

1) Launch RegEdit:

2) Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP

3) Add a new DWORD (32-bit) value

4) Name it ‘NoRun’ not including the quotes

5) Double click the new property

6) In the Value data field type ’1′ not including quotes and click OK

7) Re-boot your computer

You should now find that Apache will start on port 80!

Answer 6

Just thought I would put my input in: I stopped service MsDepSvc (AKA: Web Deployment Agent Service) and this solved the issue.
