I installed Apache 2.2.11 on the Windows XP portion of my desktop workstation for development purposes, but I got a lot of ambiguous errors when starting from the Apache Service Monitor or the Windows start menu.<\/p>\n

Finally, when I started Apache from the command line I got a more informative error:
\n(OS 10048) Only one usage of each socket address (protocal\/network address\/port) is normally permitted. : make_sock: could not bind to address 127.0.0.1:80 no listening sockets available, shutting down<\/p>\n

It turns out, I had Skype running, which by default binds to ports 5520, 80, and 443. There are several solutions:
\n<\/p>\n

    \n
  1. Quit Skype and don’t run Skype and Apache at the same time. Not ideal, but it works.<\/li>\n
  2. Change which port Apache uses. In your Apache2\/conf\/httpd file, change the line “Listen 80” to something like “Listen 8888”. Apache should start, but you’ll need to access it via http:\/\/localhost:8888 instead of merely http:\/\/localhost<\/li>\n
  3. Change which ports Skype uses for incoming connections. Go to Tools–Options–Advanced–Connection<\/em> and un-check the box next to “Use port 80 and 443 as alternatives for incoming connections.”<\/li>\n<\/ol>\n

    As far as I can tell, the last option has no ill-effect on Skype, although it might if your firewall or router is blocking port 5520.<\/p>\n

    I ended up installing Apache 2.0 in addition to Apache 2.2, as I was having trouble with mod_perl with the latter. I ran into the same issue there as well, and once I quit Skype I was able to start Apache.<\/p>\n

    Strangely enough, I now seem to have both Skype and Apache running and both listening on port 80, so perhaps I’ve misdiagnosed the problem completely.<\/p>\n","protected":false},"excerpt":{"rendered":"
