The wampapache service terminated with service-specific error 1 (0x1)

Many people must have seen this error. I just installed WampServer 2, and got it. An analysis of the problem results in the following possible causes:

  • a misconfiguration in your httpd.conf. This is the most common. To resolve it, go to the command line (Start > Run > CMD), and enter “httpd.exe –S” in the apache\bin folder.
  • port 80 is already in use. This can happen because you have another application, e.g. IIS running on port 80. Actually there is no reason you shouldn’t be able to use both, just not at the same time. From the Wamp menu you can choose Apache > Test port 80 and it will tell you which service is using it. To stop IIS you will have to go to Control Panel > Adminstrative Tools > Services and stop the World Wide Web Publishing service.
  • your firewall is blocking port 80. All firewalls are different. First, just stop the firewall to test if it’s the cause of the problem. If it is, you need to add 127.0.0.1 to the ‘safe list’.
  • Update: I recently found the ‘IIS management service’. This can also interfere with apache, so stop it if you don’t need it.
  • Update 2: Thanks, Anil, for the Skype issue. I had that one as well actually.. So, guys, just stop Skype (right click in the task bar, and exit the app). Then start Wampserver and you can restart Skype. Or change the Skype port numbers. See the Skype support page.
  • Update 3: Check the ip addresses in the apache conf\httpd.conf file. There should be a line saying Listen x.x.x.x:80, with your ip address. You can either try to add a line for 127.0.0.1 (local address) or you can put your actual IP address in there. If the DHCP server of your router has issued a new address it may be different from last time, especially if you use wireless a lot. To check your local IP address, go to the command line (Start > Run > CMD) and enter “ipconfig”.
  • Update 4: If you have Microsoft Sql Server installed, even though the IIS service is disabled, it keeps a web service named httpapi2.0 running. You should stop the service named ‘web deployment agent service’. Thank you Griffith.
  • Update 5: You should also stop ‘SQL Server Reporting Services’.

  1. I run into this once in a while and I forget that sometime I adjust the
    *** Listening Port in http.conf ***
    for other PC’s I test from on the local LAN !!

    I am posting so when I come looking for the answer again I will see this …LOL!
    Check yer listening port assignments !!

    Thanks for the post here.
    Cheers,

  2. Nother thing you might want to look at is that if you have any aliases configured that they are in fact connected and resolving properly. Easiest way is to empty your wamp/alias directory, copy the .conf files to somewhere and restart all services. If it restarts you’ve found the problem, you’ll need to test each .conf file to find out which one/ones is causing the problem

  3. Thanks Marty Peet, I’d forgotten I was half way through creating a .conf file in the alias directory. Things are working again!

  4. for windiws 7 in order to have the iis started all you need to do is to stop the iis and it will work. thanks for your help

    1. So, to start IIS I have to stop IIS? That doesn’t make any sense. I think you mean you have to stop IIS in order to start apache, but still you could run into these port issues with Skype, etc.

  5. Thanks for this! I have xampp & wampserver2 installed. I couldn’t get wampserver2 services to start up this morning. I quit skype etc, didn’t make any difference.

    I suddenly remembered that xampp had installed apache/mysql as services, but these do not appear in the services list, unlike the wampserver2 services (wampapache / wampmysqld) so I uninstalled xampp’s services via xampp’s control panel and now I can easily switch between xampp / wampserver2 whenever I want.

  6. Also and its mostly my error but when you are using virtual hosts make sure when you are defining your DocumentRoot directories you dont use \ [backslashes] but / [forward slashes].

    This had me baffled for a while until I ran httpd.exe -S which told me my problem 🙂

    Hope this helps others

  7. Thanks for the reminder about stopping other services. In my case, it was the Flash Media Server that grabbed port 80, so I stopped it, then started WAMP, then re-started the Flash Media Server.

  8. Hi,

    I also got the same error for a while.Then I found from this page that the IIS is giving problem. I removed the IIS as I do not need it now, Wamp starts working fine.

    Thanks.

  9. Also, If you have installed SQL Server, feature SQL Server Reporting Service can use port 80, which can prevent Apache service to start

  10. ROFLMAO!!!
    what a lameass system… i typed in the httpd.exe -s command and it said my documentRoot folder i wrong…

    why the fuck isnt the error message saying this??

  11. Thanks like anything man!! My case was the first one and i knew it. I desperately needed some guidance in the right direction.

  12. Thanks Michiel, I spent 3 days on trying to get this operational. Your first paragraph indicated a syntax error on line 18 – from must be used after Allow.

  13. Thanks, after executing the command httpd -S I came to know the error and got the solution too… Now my wamp server is working…

  14. I have to thank you for the efforts you’ve put in penning this
    site. I am hoping to check out the same high-grade blog posts from you in the future as well.
    In truth, your creative writing abilities
    has encouraged me to get my very own website now 😉

  15. Hello, Michiel. The first advice about “httpd.exe –S” is very useful. Thank you so much. I had trouble configuring Apache to work with PHP7 and syntax check was a lifesaver
