13. Perl module Devel::Symdump

If you intend to use the mod_perl programming language support with your Apache web server, it can be interesting to install the small perl module program named Devel::Symdump. This third party module will allow you to inspect perl's symbol table and the class hierarchies within a running program. To build and install it, follow these steps.

These are the package(s)

Devel-Symdump Homepage:http://www.perl.com/CPAN/modules/by-module/Devel/
You must be sure to download: Devel-Symdump-2_00_tar.gz
Devel-Symdump version number is 2.00

        [root@deep ]/# cp Devel-Symdump-version.tar.gz /var/tmp/
        [root@deep ]/# cd /var/tmp/
        [root@deep ]/tmp# tar xzpf Devel-Symdump-version.tar.gz

Move into the new Devel-Symdump directory and type the following commands on your terminal to compile and install the module on your Linux server:

        [root@deep ]/Devel-Symdump-2.00# perl Makefile.PL
        [root@deep ]/Devel-Symdump-2.00# make 
        [root@deep ]/Devel-Symdump-2.00# make test 
        [root@deep ]/Devel-Symdump-2.00# make install 

Once the module has been installed on your system, you must include in your /etc/httpd/conf/httpd.conf file the following lines to be able to see the status of different Perl modules on the server: Edit the httpd.conf file, vi /etc/httpd/conf/httpd.conf and add the following lines:

  1.           <Location /perl-status>
              SetHandler  perl-script
              PerlHandler Apache::Status
              Order deny,allow
              Deny from all
              Allow from

  2. You must restart the Apache web server for the changes to take effect: To restart Apache, use the following commands:

            [root@deep ]/# /etc/rc.d/init.d/httpd restart

            Shutting down http:                                        	[  OK  ]
            Starting httpd:                                            	[  OK  ]

  3. Finally, we must test the new Devel-Symdump module to be sure that we can see status of different Perl modules on the server.

To verify that it works, points your web browser to the following address: http://my-web-server/perl-status/. The <my-web-server> is the address where your Apache web server resides.

Mod perl

Please as always Cleanup :

        [root@deep ]/# cd /var/tmp
        [root@deep ]/tmp# rm -rf Devel-Symdump.version/ Devel-Symdump-version.tar.gz
