HTML Page Template Framework

'Glue' web pages on the monitoring server are generated through the Mason Delivery Engine. In other words, Mason is a Perl based template system used for formatting the primary web pages of this server. It requres the use of Apache and mod_perl. Here is what I do to install Mason for my needs. As the monitoring server relies on NetDisco tables, a portion of the installation process revolves around initializing the NetDisco PostgreSQL database.

Installation

Install the packages:

apt-get install libhtml-mason-perl
apt-get install libdbi-perl
apt-get install libdbd-pg-perl
apt-get install apache2-dev
apt-get install libapache2-mod-apreq2
apt-get install libapache-dbi-perl
apt-get install libmasonx-request-withapachesession-perl
apt-get install libapache2-request-perl
ln -s /etc/apache2/mods-available/apreq.load 
/etc/apache2/mods-enabled/apreq.load

Add the following line into '/etc/postgresql/7.4/main/pg_hba.conf':

local   netdisco    netdisco     trust

Create and load database:

/etc/init.d/postgresql-7.4 restart
su - postgres
psql template1
create user netdisco;
create group netdisco user netdisco;
create database netdisco with owner netdisco;
\q
psql netdisco -U netdisco < netdisco.dump

exit

Add the following lines into /etc/apache2/sites-available/default:

    PerlModule HTML::Mason::ApacheHandler
    <LocationMatch "(.html|.txt|.pl)$">
        SetHandler perl-script
        PerlHandler HTML::Mason::ApacheHandler
    </LocationMatch>
    <LocationMatch "(.m(html|txt|pl)|dhandler|autohandler)$">
        SetHandler perl-script
        PerlInitHandler Apache::Constants::NOT_FOUND
    </LocationMatch>

        <Directory />
                Options FollowSymLinks
                AllowOverride None
                AllowOverride AuthConfig
                AuthType Basic
                AuthName "Password Required"
                AuthUserFile /etc/apache2/sites-available/password.file
                Require user admin
        </Directory>

Create a password file with a username admin:

htpasswd -c /etc/apache2/sites-available/password.file admin

Restart Apache:

/etc/init.d/apache2 restart
