Install it as a service with cygrunsrv:

Re: Starting Apache

Nope, I can only start inetd but not apache, nor cron.  In case of
inetd I learned that after "cygrunsrv -I ineted -p
/usr/sbin/inetd.exe" I had to reboot the W2K, otherwise cygrunsrv -S
inetd started inetd but it died shortly after.  Anyway cygrunsrv is a
mysterious existence for me now.  I wanted to pursue the reason why I
am not successful using cygrunsrv but the snapshot I got
cygwin-src-20010707.tar.bz2 does not seem to contain its source code.

For now I am forcing myself not forgetting to start httpd when I
reboot the server.  Sigh...

inetd has a builtin install mechanism.
Read /etc/doc/Cygwin/inetutils-1.3.2.README
and  /etc/doc/Cygwin/cron...

after running $ inetd --install-as-service
it should work.
Don't miss the other points in the README...

I had also difficulties running apache as a service, but cygrunsrv is
much more advanced since then.
AND apache runs, only problem i had was that it seems to die
if you look in the service manager. In the taskmanager there
was to be seen that still some instances of apache were running.

The document I have written shows the way it _should_ be working. Unfortunatly I
had the same problems and reported them to Corinna, but there is yet no solution
on that. I know from the previous CAMP distribution that a tool called "invoker"
(not Cygwin specific) was able to "install" cygwin based ports and daemons as NT
services. It is freeware and I have a copy on

    http://kannel.dev.wapme.net/dist/support/

No, the -X switch means that httpd should not fork childs and should run in
single process mode. It will serve request as usual, but simply without forking
extra childs for any new imcoming request.

Right, if the invoking parent process (which is the bash) is terminated - via
closing the window - all subprocesses, which is httpd too will terminate.

Basicly it only helps out to detach from the current shell, which does not mean
that - at least on Cygwin - it will survive the dead of the prarent process, the
shell.

That's right. Apache closes because if you stop the shell, the shell sends
SIGKILL to parent httpd and that one sends the signals to it's childs. So if
there wouldn't be a parent httpd then the closing of the bash window would _not_
cause the childs to stop. But Apache needs the parent httpd to organize the
scoreboard, which holds the information of all childs and their states.

As i tried the last time, apache runs and serves well. But the parent 
process died (watched from windows service manager). However the 
childs were running and serving, and also was the parent which 
controls the childs.

With that option, apache will run, but it will not serve requests, it 
is for debugging only.

Yes, it needs the shell which it was started from. This is the 
'normal' behaviour of every daemon on cygwin which is started from 
the shell. If you start them with cygrunsrv they don't need the shell.

It is detached, which means it is running in the background.
It is a special Apache mechanism that i don't understand really.
The parent lives on, it is forking off some childs and puts itself in 
the background. 
Other daemons fork off and let the parent die to stay in background 
with the childs, they need the start shell, too.

Re: Starting Apache

[Tak Ota]

I wonder if things written in this page are true.

  http://apache.dev.wapme.net/manual/cygwin.html#serv

/usr/doc/Cygwin/cygrunsrv.README mentions the caveat about running
daemon that forks.  httpd is such a daemon therefore it is not
possible to control httpd by -S and -E.  The direct child created by
cygrunsrv will not stay alive.

Even with this understanding there still is a fact that I cannot
explain its mechanism.  Though httpd quits from cygrunsrv point of
view the forked background child processes should continue to run
however this is not the case.  After service installation by

  cygrunsrv -I apache -p /usr/local/apache/bin/httpd

"cygrunsrv -S apache" does not leave any new processes.  Instead, it
produces the next error.

$ cygrunsrv -S apache
cygrunsrv: Error starting a service: QueryServiceStatus:  Win32 error 1062:
The service has not been started.

Next, I tried to run httpd as a normal process instead of a daemon.
Although it is not recommended httpd has an option -X for debugging
purpose to keep httpd running without forking.  I've tried the
following for installing the service.

  cygrunsrv -I apache -p /usr/local/apache/bin/httpd -a -X

Somehow this does not work either.  I get the same 1062 error.

There is another mysterious and unexplainable fact.  When I open two
Cygwin terminal windows and run /usr/local/apache/bin/httpd manually
from one of the terminal, it forks off the background process and
comes back to the bash prompt.  From both of the terminal windows,
'ps' shows the httpd processes running.  What is strange is if I close
the window which started the httpd, all those background process are
terminated.  "Running Apache for Cygwin" section of the document
states:

  If installed to the default Apache layout directory you can start
  httpd as follows:

    $ /usr/local/apache/bin/httpd

  An explicit background & indicator is not required. The resulting
  parent process is detached from the current terminal. Check the
  global error_log to see if Apache has started cleanly without any
  major problems.

However, the fact seems to be the spawned processes are still bound to
the terminal thus terminated when the terminal closes.

Does anyone have answer to the above mystery?

Hmm, on my machine the latest cron (3.0.1-4) and the latest sshd
(2.9p2-1) are both running fine with the latest cygrunsrv (0.94-1).

Thanks for the information.  I'll try this when my cygrunsrv
environment is fixed.  Somehow my cygrunsrv is broken.  It can't start
cron either.  So I tried cygrunsrv -R inetd then -I to reinstall it.
Now inetd doesn't work anymore either.  A few minutes ago I could
telnet and ftp to this machine but now no service is available.
Hmmm....

I wonder the new cron I installed today is doing something bad.

Starting Apache

[Tak Ota]

Hi,

I just downloaded Apache 1.3.20.  It compiled/installed/ran out of the
box without any tweaking at all.  It was quite an impressive and
delightful experience.  Thank you.

BTW, I am now trying to automate the following work, in case I reboot
the machine.

/usr/local/apache/bin/apachectl start

What is the equivalent mechanism as /etc/rc.d/init.d/ under Cygwin?
