Restart

[cheesecaker]

The Restart shortcut for Apache doesn't work properly for me. The restart seems to have succeeded, but then I can't access any pages on the server. Requests time out. It does work when I stop then server, then start the server. I've written a batch file to do it automatically, but I'd still like to know why a regular restart doesn't work.

Anybody? I can provide further information if necessary.

Hi,

which error code is appearing in the browser? 403, 404? Did you check if port 80 (and maybe 443 for ssl) are open (netstat -lntp)? What's apache saying in error.log?

Well, here's the log for the restart.

I think everything's fine until line 10. Why does it exit again?

My restart command is as follows:

httpd -n "Apache2" -k restart

And it seems like it works, but then the server just doesn't respond.

Anybody else have an idea?

It looks like two threads did not stop, meaning you didn't get access to the port back.

Try a full stop, and search through the output of ps to see if any httpd/apache threads are still running, and kill them. Then start the service again.

Again, it works if I do httpd -k stop then httpd -k start. But a full stop/start of the service takes much longer than a simple httpd -k restart. That's why I'm asking.

Does the graceful restart option work?

might be multiple instances opening.. like connection pools ... they cause this to occur...
also may me its already started in you dont see the refreshed version ...
well this is a major issue with apache ... me face it often ... that's why me shifted to WAMP server..

http://www.wampserver.com/en/

its a much more user friendly ... for PHP i mean ...

I'm fairly certain that httpd -k restart is graceful by default.

Also, I can't switch servers. I'm committed to Apache, I'm learning it's modules, etc. It took forever to get it set up the way it is now. Switching server software is not an option.

Well then, have you tried the un-graceful approach?

I'm not sure how to do that. I'm pretty sure the ungraceful approach is simply shutting down the apache2 windows service and restarting it. Again, though, that's what I'm trying to avoid. Takes a while.

I'm sorry, I completely overlooked that you were running on Windows.
How did you go about installing Apache? Did you use the Apache standalone installer, or did you opt to go with a bundled package, such as WAMP or Netserver?

Hi,

as far as I can see from the log port 443 is opening again, so you should be able to access your html pages via https. What's missing, is port 8080/http. Looks as if it could not be detached while stopping the Apache. Could be there's some old, broken requests still blocking a socket.

Try restarting the Apache after a fresh start, when there has been no http call so far. Still the same problem? If not, have a look at the ones behind Apache (e.g. PHP and MySQL).
