Re: Ubuntu and mod_perl
you have compiled and installed one apache, and you made it start at boot time, you must disable it or remove it ( do not let it start at boot time ) 2011/5/18 Tom Kane : > I tried to incorporate suggestions I've received.

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.
RE: Ubuntu and mod_perl
If you are looking to run something on apache startup: PerlRequire /path/to/startup.pl -Original Message- From: Tom Kane [mailto:t.k...@mindspring.com] Sent: Tuesday, May 17, 2011 5:23 PM To: modperl@perl.apache.org Subject: Ubuntu and mod_perl 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 problem lies in my confusion as to (1) where to point ServerRoot, and (2) where I'm supposed to put my perl scripts. These are all pretty elementary, I suppose, but if anyone can shed any light, I will be very appreciative. Tom

I also had to do the following: sudo ln -sf /usr/lib/libgdbm.so.3.0.0 /usr/lib/libgdbm.so The libgdbm issue actually occurred prior to the perl problem. I hope this helps. I am now trying to find the settings for mod_perl in the /etc/apache2 configuration. My startup.pl file returns an error message that I can't use 'use'. Tom Maybe as a tip to both Tom and Marco : It all depends if your focus is on installing apache and perl and mod_perl, or rather on just using them to achieve another main goal. But if your main aim is not the installation of apache and mod_perl, then I would recommend to both, to use the software packaging system of your respective flavors of Linux, to install Apache, perl and mod_perl using these pre-packaged versions. That will take just a few minutes, and will work without having to spend hours resolving dependencies, fixing missing links (maybe wrongly), and creating your own startup scripts. And the hours you save will then be available for achieving your main goal.

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.

Hi Tom, if you don't need to compile the software yourself, and you're just starting, I would suggest an easy path: # Install the relevant packages sudo apt-get install apache2 apache2-mpm-prefork sudo apt-get install libapache2-mod-perl2 libapache2-mod-apreq2 # Enable the apreq and mod perl modules a2enmod apreq a2enmod perl # Restart apache /etc/init.d/apache2 restart -- Cosimo
