Apache 2.2.4 does not start - no errors

We are running on Tru64 Unix. Downloaded 2.2.4, and installed.
Just tried vanilla version and changed only the user/group and
ServerName in httpd.conf. When we start as
/usr/apache/bin/apachectl start, it just exists without
generating any error. Exit code form script is 0 and no
httpd process is running. What may be going on?
Thanks.

- try running under truss or strace
- try starting directly (ie /usr/apache/bin/httpd)

what happens?

Another thought... when you say "no errors" you mean "no errors to the
screen", right? But what's in the error log?

> Exit code form script is 0

No big surprise... apachectl is just a shell script that forks httpd. If
httpd fails, apachectl can still exit normally...

Should have mentioned that we had tried starting
httpd directly and got same results.
Also there is nothing in the error log.
We had tried running with trace and last statement seem
to be fork(). There was a pid associated with fork().
Then next statement was exit(0).

When tracing a program you have to make sure it traces child processes
too, otherwise you will see what happens after the fork. Which option
you need to give to trace on your OS I don't know, so consult the man
page.

On Solaris I use "truss -f" when tracing problems. The -f option tells
truss to follow children too.

One possible reason for your problem (I've seen this before) might be
the user and group directives in your httpd.conf. The default values
apache ships with (-1) is not suitable on some variants of Unix. Edit
your httpd.conf and make set the user and group to a real existing
user and group on your system. (nobody:nobody if exists will do fine,
but I usually create a apache user and www group).

RE: Apache 2.2.4 does not start - no errors [In reply to]

Found the following information from trace.

bind (4, 0x14002fee0=<2/INET, 80, 0.0.0.0>, 16) = 0

It seems there is an attempt to bind to address 0.0.0.0
instead to the IP address of the machine. /etc/hosts
file does contain mapping of name to IP address.

0.0.0.0 normally means "bind to anything". I don't think that's your
problem. Apache by default will listen on all interfaces. If a bind
fails this will give you an error message in your log.

That you don't even get an error log point to something more
fundamental. Have a look in your trace output for the lines where
apache opens its log files.
