Subject Re: I can't get mod_perl 2.0 working :(
Date Fri, 14 Oct 2005 06:14:21 GMT
Yes of course I have perl installed.  I even posted my output from perl -V 
(see output below).  I wound up giving up on the static mod_perl and built 
it dynamically.  I have it working...I think.  I can get the httpd server to 
start, and it loads the perl_module as well as Apache::Session and 
Apache::DBI without complaining.  When I try to access the page through a 
browser though, I get an "Internal Server Error" which usually happens when 
I have an error in the code (or at least, it happens on the machine that 
this is running on right now.  I'm trying to move the code over to a newer 
machine...).  At least httpd doesn't complain about the conf file when I 
start it up though, and at least it's not timing out when I access the page 
through a browser.  I think I can get figure it out from here though.  I'll 
stick with dynamic modperl for right now and see what the performance is 
like.  If I need to, I'll make it static later.  Thanks.

-Brandon

Hi Brandon,

mod_perl : mod_perl-2.0.1
Apache   :  httpd-2.0.54

Do u have Perl Installed - Version 5.8.0 minimum or greater.

The actual building process is as follows : (1) APACHE (2) PERL (3) MOD_PERL

Plz don't extract all the tar.gz files at a stretch. Extract one after
the other. I mean, first extract httpd, build it and then extract
perl, build it and finally extract modperl.

So, First build Apache as follows : -

Extract in /usr/local/src and descend into the directory httpd-2.0.54

--prefix is the directory where u want to install apache. It is
recommeded that the directory where u want to install apache, install
modperl , install perl are all under one parent directory. So, create
a directory under /usr/local/src as apache2 and execute this command :
-

httpd-2.0.54# ./configure --prefix=/usr/local/src/apache2 --with-mpm=prefork

Ofcourse , make && make install later in httpd-2.0.54

Download PERL from http://cpan.org/src/ - perl - 5.8.0 or greater.

Next , Extract it and create a seperate directory in /usr/local/src as
"perl" and descend into the directory which u had extracted and
execute : -

/Configure -des -Dprefix=/usr/local/src/perl -Dusethreads

Execute make && make test && make install

Before proceeding with the installation of mod_perl 2.0, it's
advisable to install at
least the LWP package into your newly installed Perl distribution so
that you can
fully test mod_perl 2.0 later. You can use CPAN.pm to accomplish that:

/usr/local/src/perl/bin/perl -MCPAN -e 'install("LWP")'

This takes atleast 20 min. to finish and u r prompted for a set of
commands and other questions. Choose Default ( Press Enter for every
question ). If prompted about the website for CPAN, Enter it as :
http://cpan.org

Finally, Build MOD_PERL as follows : -

Extract the directory modperl-2.0.1 and descend into the directory and
execute : -

/usr/local/src/modperl-2.0.1# perl Makefile.PL
MP_AP_PREFIX=/usr/local/src/apache2

Now execute : make and then copy :

/usr/local/apache2/modules/mod_perl.so to /etc/httpd/modules and Enter
this line in httpd.conf

LoadModule perl_module modules/mod_perl.so

Now execute : make test and it should show u that " All tests successful "

Finally execute : make install
