I tried to incorporate suggestions I've received. After restarting apache2, 
this is what happened:


tomkane@sfq:~$ /etc/init.d/apache2 start
 * Starting web server apache2
[Tue May 17 20:12:34 2011] [warn] module perl_module is already loaded, skipping
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
 [fail


Now apache2 won't even start. It's not as if my network address is gone because 
I see it's still there at boot time. I'm going a little daft now. It's not as 
if I haven't seen a message like this before, but I've forgotten what to do 
about it. Any suggestions?

Once again, I want to thank everyone for their suggestions.

You should have a line in your httpd.conf that looks something like
this. If not, you will need to add it.

PerlPostConfigRequire /etc/apache2/conf.d/startup.pl

I think that's a bit confused (and confusing).

Under Ubuntu/Debian, the directory /etc/apache2/conf.d is meant to contain bits of
configuration which *apache* reads and interprets. So whatever is in there, should not be
perl scripts. It should be Apache directives, like inside httpd.conf.

(And that is also why you get (from Apache) that error about "use" being an invalid
directive. It is, for Apache, which does not understand perl.)

Place your perl startup.pl script somewhere else (for example directly in /etc/apache2),
and then, in /etc/apache2/conf.d, create a file with the single text line :

PerlPostConfigRequire /etc/apache2/startup.pl

---

Now, let's mentally reboot and think about the future :

Later, you are (also) going to need a place to put your own mod_perl modules (the ones you
are going to create).
So I suggest to create a directory for that, for example : /usr/local/lib/modperl, and
make it readable and "executable" by the user under wich Apache runs (www-data ?).

Then, place your startup.pl script there.

Then, in /etc/apache2/conf.d, place a file (or modify the above file) with the
line :

PerlPostConfigRequire /usr/local/lib/modperl/startup.pl

and in your startup.pl script, add a line

use lib "/usr/local/lib/modperl";

and restart Apache.

After that, you can place all your newly-developed perl modules inside the directory
/usr/local/lib/modperl, and Apache/mod_perl will find them.

Thanks for all of the help. Just to let everyone know, it was embarrassing how 
simple it was to install mod_perl with the suggestions that I received from 
Cosimo Streppone earlier in the day. I didn't know that the apt-get and a2enmod 
steps were available as the perl.apache2.org mod_perl 2 documentation said I 
had to build both apache2 and mod_perl from the latest source from scratch. 
(Admittedly, I may have read too many assumptions into that.)

I will say that the "apt-get install" on apache2 did nothing as everything was 
already there on my system. The "apt-get install" on mod_perl did download a 
fair amount, however. And, thankfully, when I restarted apache2 after the 
a2enmod steps, I saw that mod_perl was indeed running. 

Had I only known the above steps, I'd have saved several days on the build 
process -- days that I would have much preferred applying to my application.

Now, I have another issue: I have created a startup.pl file and placed it into 
the conf.d directory. However, when I restart apache2 I get an error message to 
the effect that the first 'use' statement is a syntax error. I'm sure that my

Tom, it seems you are missing gdbm-devel and perl-devel packages.  To get
the appropriate .a/.so/.h files, you usually have to add -devel (or -dev)
flavors of various system components to build new software against them.

Re: Install mod perl


marco,

under which version/distribution of Linux are you doing this ?
(the answer I am looking for is something like Debian or Ubuntu or RedHat..)

The reason I am asking you, is that each of these distributions has a "package" system, 
which you can probably use to install apache and perl and mod_perl using just a couple of 
commands, and not have to bother doing it "the hard way".


See the answer of Cosimo Streppone previously today in the same mod_perl list, subject : 
Ubuntu and mod_perl.

Thomas, could you please check if the patch at

Steve, I have tried your patch on my linux box. It passes all tests 
successfully. So, I think go ahead and commit it.

One thing I don't catch, can this thing happen only in 
mpxs_Apache2__RequestRec_rflush()? I believe it can also happen in all 
the other write operations. If the process crashes on this error I think 
they should also be fixed. Though, without a proper test case it's like 
fishing in murky waters.

You probably want this handler:

PerlPostReadRequestHandler

http://perl.apache.org/docs/2.0/user/handlers/http.html#PerlPostReadRe
questHandler

There's a code example included on that web page, and then in
httpd.conf you'll need to specify your source code file with the
PerlPostReadRequestHandler configuration directive.
