Setting up mod_perl

[asmita.joshi]

Hi,

I am trying to install and get mod_perl up and running.

Apache and perl versions are below:
[Mon Mar 10 11:10:50 2008] [notice] Apache/2.2.8 (Unix) mod_perl/2.0.3
Perl/v5.8.5 configured -- resuming normal operations
---

This is the error I see in apache error_log when firefox tries to open
http://localhost/perl/mod_perl_rules1.pl:
[Mon Mar 10 11:10:55 2008] [error] [client 127.0.0.1] (13)Permission
denied: access to /perl/ denied
[Mon Mar 10 11:11:04 2008] [error] [client 127.0.0.1] (13)Permission
denied: access to /perl/ denied
---

Firefox shows this error:
"Forbidden
You don't have permission to access /perl/mod_perl_rules1.pl on this
server."
---

The file mod_perl_rules1.pl is just the bare minimal perl file from
the mod_perl tutorial.
#!/usr/bin/perl -w
print "Content-type: text/plain\n\n";
print "mod_perl rules!\n";
---

Relevant (acc. to me) parts of httpd.conf are below:
<Directory "/usr/local/apache2/cgi-bin">
AllowOverride None
#Options None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>

<IfModule mime_module>
AddHandler cgi-script .cgi .pl
</IfModule>

Alias /perl /home/<uname>/modperl
<Directory /home/<uname>/modperl>
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders
Options +ExecCGI
</Directory>
---

Anyone have any clues what is going wrong with my apache/modperl
configuration?

as a note: While installing modperl, 1 test failed out of some 3000+
tests...I moved on with the installation since I didnt quite
understand the error. I don't know where to find details of that
failed test (i may have to install modperl again? or just run make
test again). Let me know if you need to know about this failed
test...till then i will try to find out how to get at the test report
to find out which one failed.

Thanks in advance for your inputs,
Asmita

Are you sure the user the *webserver* runs as (not just you), has
permission to read and execute that file?

You should be able re-run "make test" from the build directory.

[...]

This has to do with apache, not perl.. but..

If that's the exact entry, then you need to put the actual
directory there instead of '/home/<uname>/modperl' e.g.
if 'user1' is your username and the directory containing
your script is '/home/user1/modperl':

Alias /perl /home/user1/modperl
<Directory /home/user1/modperl> ...

Both /home/user1 and /home/user1/modperl need to be executable
by the user running the web server. Also, the script residing there
needs to be executable by that user. Without knowing that username,
you could make them all executable:

e.g.
chmod 755 /home/user1 /home/user1/modperl
/home/user1/modperl/mod_perl_rules1.pl

 

[asmita.joshi]

these are permissions of the directory and of the perl script in that
directory:
(I also tried with my username instead of nobody. same result. )

drwxr-xr-x 2 nobody nobody 4096 Mar 10 12:21 modperl

-rwxrwxrwx 1 nobody nobody 84 Mar 7 16:03 mod_perl_rules1.pl
---

I see the same error..

[Mon Mar 10 12:23:47 2008] [error] [client 127.0.0.1] (13)Permission
denied: access to /perl/mod_perl_rules1.pl denied
---

I am running make test now. Had tried to run it some time ago, it
failed. If I get it to succeed then I will post the error I see.

Do you have any other places I can check what is going wrong?

Thanks for your responses.

drwxr-xr-x 2 nobody nobody 4096 Mar 10 12:21 modperl

what about the parent directory/directories of that directory?

Finally, I have copy pasted only the errors from t/logs/error_log
(sorry for the clutter). There seem quite a few errors in it now that
I go back and look carefully.

To reply to your earlier post:

I checked user permissions for the parent directory. /home/<uname> was
executable only for root. So I changed it to 755 now:
drwxr-xr-x 32 nobody nobody 4096 Mar 10 12:23 <uname>

The error changed in apache error_log. It reads this now:
[Mon Mar 10 12:46:26 2008] [error] [client 127.0.0.1] client denied by
server configuration: /home/<uname>/modperl/mod_perl_rules1.pl

It seems I may have moved one step forward..So is the problem now in
my httpd.conf?

Thanks
Asmita

Anyone have any clues what is going wrong with my apache/modperl
configuration?

One problem which might be occurring is that mod_perl doesn't like
running files which are viewable by the web server (under /var/htdocs/
or similar). So if your file is in a place where it can be served up
as if it was an HTML file, then mod_perl refuses to run it as a
script.

That doesn't seem to be the case from what you described, but it might
be worth checking.
