 | 
						|
 | 
						|
=head1 Dependencies
 | 
						|
 | 
						|
Netdisco has several Perl library dependencies which will be automatically
 | 
						|
installed. However it's required that you first install the following
 | 
						|
operating system packages:
 | 
						|
 | 
						|
On Ubuntu/Debian:
 | 
						|
 | 
						|
 root:~# apt-get install libdbd-pg-perl libsnmp-perl libssl-dev libio-socket-ssl-perl curl postgresql build-essential
 | 
						|
 | 
						|
On Fedora/Red-Hat:
 | 
						|
 | 
						|
 root:~# yum install perl-core perl-DBD-Pg net-snmp-perl net-snmp-devel openssl-devel curl postgresql-server postgresql-contrib make automake gcc
 | 
						|
 root:~# postgresql-setup initdb
 | 
						|
 root:~# systemctl start postgresql
 | 
						|
 root:~# systemctl enable postgresql
 | 
						|
 | 
						|
On BSD systems please see L<our BSD tips|https://github.com/netdisco/netdisco/wiki/BSD-Install>.
 | 
						|
 | 
						|
With those installed, please check that your system's clock is correct.
 | 
						|
 | 
						|
Create a user on your system called C<netdisco> if one does not already exist.
 | 
						|
We'll install Netdisco and its dependencies into this user's home area, which
 | 
						|
will take about 250MB including MIB files.
 | 
						|
 | 
						|
 root:~# useradd -m -p x -s /bin/bash netdisco
 | 
						|
 | 
						|
Netdisco uses the PostgreSQL database server. Install PostgreSQL (at least
 | 
						|
version 8.4) and then change to the PostgreSQL superuser (usually
 | 
						|
C<postgres>). Create a new database and PostgreSQL user for the Netdisco
 | 
						|
application:
 | 
						|
 | 
						|
 root:~# su - postgres
 | 
						|
  
 | 
						|
 postgres:~$ createuser -DRSP netdisco
 | 
						|
 Enter password for new role:
 | 
						|
 Enter it again:
 | 
						|
  
 | 
						|
 postgres:~$ createdb -O netdisco netdisco
 | 
						|
 | 
						|
You may wish to L<amend the PostgreSQL
 | 
						|
configuration|https://github.com/netdisco/netdisco/wiki/Install-Tips#enable-md5-authentication-to-postgresql>
 | 
						|
so that local connections are working.  The default PostgreSQL configuration
 | 
						|
also needs tuning for modern server hardware. We recommend that you use the
 | 
						|
C<pgtune> Python program to auto-tune your C<postgresql.conf> file:

 | 
						|
=head1 Installation
 | 
						|
 | 
						|
The following is a general guide which works well in most circumstances. It
 | 
						|
assumes you have a user C<netdisco> on your system, that you want to perform
 | 
						|
an on-line installation, and have the application run self-contained from
 | 
						|
within that user's home. There are alternatives: see the
 | 
						|
L<Deployment|https://github.com/netdisco/netdisco/wiki/Install-Tips>
 | 
						|
documentation for further details.
 | 
						|
 | 
						|
To avoid muddying your system, use the following script to download and
 | 
						|
install Netdisco and its dependencies into the C<netdisco> user's home area
 | 
						|
(C<~/perl5>):
 | 
						|
 | 
						|
 su - netdisco
 | 
						|
 curl -L https://cpanmin.us/ | perl - --notest --local-lib ~/perl5 App::Netdisco
 | 
						|
 | 
						|
Link some of the newly installed apps into a handy location:
 | 
						|
 | 
						|
 mkdir ~/bin
 | 
						|
 ln -s ~/perl5/bin/{localenv,netdisco-*} ~/bin/
 | 
						|
 | 
						|
Test the installation by running the following command, which should only
 | 
						|
produce a status message (it's just a test - you'll start the daemons
 | 
						|
properly, later on):
 | 
						|
 | 
						|
 ~/bin/netdisco-backend status
 | 
						|
 | 
						|
=head1 Configuration
 | 
						|
 | 
						|
Make a directory for your local configuration and copy the configuration
 | 
						|
template from this distribution:
 | 
						|
 | 
						|
 mkdir ~/environments
 | 
						|
 cp ~/perl5/lib/perl5/auto/share/dist/App-Netdisco/environments/deployment.yml ~/environments
 | 
						|
 chmod 600 ~/environments/deployment.yml
 | 
						|
 | 
						|
Edit the file ("C<~/environments/deployment.yml>") and change the database
 | 
						|
connection parameters to match those for your local system (that is, the
 | 
						|
C<name>, C<user> and C<pass>).
 | 
						|
 | 
						|
In the same file uncomment and edit the C<domain_suffix> setting to be
 | 
						|
appropriate for your local site. Change the C<community> string setting if
 | 
						|
your site has different values.
 | 
						|
 | 
						|
Have a quick read of the other settings to make sure you're happy, then move
 | 
						|
on. See
 | 
						|
L<Configuration|https://github.com/netdisco/netdisco/wiki/Configuration> for
 | 
						|
further details.
 | 
						|
 | 
						|
=head1 Initialisation
 | 
						|
 | 
						|
The database either needs configuring if new, or updating from the current
 | 
						|
release of Netdisco (1.x). You also need vendor MAC address prefixes (OUI
 | 
						|
data) and some MIBs if you want to run the backend daemon. The following
 | 
						|
script will take care of all this for you:
 | 
						|
 | 
						|
 ~/bin/netdisco-deploy
 | 
						|
 | 
						|
If this is a new installation of Netdisco 2, answer yes to all questions. If
 | 
						|
you wish to deploy without Internet access, see the
 | 
						|
L<Deployment|https://github.com/netdisco/netdisco/wiki/Install-Tips>
 | 
						|
documentation.
 | 
						|
 | 
						|
=head1 Startup
 | 
						|
 | 
						|
Run the following command to start the web-app server as a background process:
 | 
						|
 | 
						|
 ~/bin/netdisco-web start
 | 
						|
 | 
						|
The web app listens on port 5000 (for example C<< http://localhost:5000/ >> or
 | 
						|
C<< http://yourhost.example.com:5000/ >>).
 | 
						|
 | 
						|
Run the following command to start the job control daemon (device polling,
 | 
						|
port control, etc):
 | 
						|
 | 
						|
 ~/bin/netdisco-backend start
 | 
						|
 | 
						|
I<note:> Whenever you upgrade your operating system, you should delete the
 | 
						|
C<~/perl5> directory and re-run the C<curl> command above, to update
 | 
						|
Netdisco's C library bindings.
 | 
						|
 | 
						|
I<also note:> You should take care not to run C<< netdisco-backend >> and the
 | 
						|
Netdisco 1.x daemon at the same time. Similarly, if you use the device
 | 
						|
discovery with Netdisco 2, disable your system's cron jobs for the Netdisco
 | 
						|
1.x poller.
 | 
						|
 | 
						|

 | 
						|
 | 
						|
=head1 Upgrading from 2.x
 | 
						|
 | 
						|
If you're running a version of Netdisco prior to 2.x then you should follow
 | 
						|
the full installation instructions, above. This process is for upgrading
 | 
						|
version 2.x only.
 | 
						|
 | 
						|
Before upgrading please review the latest L<Release Notes|https://github.com/netdisco/netdisco/wiki/Release-Notes>.
 | 
						|
Then the process below should be run for each installation:
 | 
						|
 | 
						|
 # upgrade Netdisco
 | 
						|
 ~/bin/localenv cpanm --notest App::Netdisco
 | 
						|
 ln -sf ~/perl5/bin/{localenv,netdisco-*} ~/bin/
 | 
						|
 
 | 
						|
 # apply database schema updates, update MIBs and Vendor MACs
 | 
						|
 ~/bin/netdisco-deploy
 | 
						|
 
 | 
						|
 # restart web service (if you run it)
 | 
						|
 ~/bin/netdisco-web restart
 | 
						|
 
 | 
						|
 # restart the backend workers (wherever you run them)
 | 
						|
 ~/bin/netdisco-backend restart
 | 
						|
 | 
						|
=head1 Tips and Tricks
 | 
						|
 | 
						|
=head2 Searching
 | 
						|
 | 
						|
The main black navigation bar has a search box which is smart enough to work
 | 
						|
out what you're looking for in most cases. For example device names, node IP
 | 
						|
or MAC addreses, VLAN numbers, and so on.
 | 
						|
 | 
						|
=head2 Command-Line Device and Port Actions
 | 
						|
 | 
						|
Most significant Device jobs and Port actions, as well as several
 | 
						|
troubleshooting and housekeeping duties, can be performed at the command-line
 | 
						|
with the L<netdisco-do> program. For example:
 | 
						|
 | 
						|
 ~/bin/netdisco-do -D discover -d 192.0.2.1
 | 
						|
 | 
						|
See the L<netdisco-do documentation|netdisco-do> for further details.
 | 
						|
 | 
						|
=head2 Import Topology
 | 
						|
 | 
						|
Netdisco 1.x had support for a topology information file to fill in device
 | 
						|
port relations which could not be discovered. This is now stored in the
 | 
						|
database (and edited in the web interface). To import a legacy topology file,
 | 
						|
run:
 | 
						|
 | 
						|
 ~/bin/localenv nd-import-topology /path/to/netdisco-topology.txt
 | 
						|
 | 
						|
=head2 Database API
 | 
						|
 | 
						|
Bundled with this distribution is a L<DBIx::Class> layer for the Netdisco
 | 
						|
database. This abstracts away all the SQL into an elegant, re-usable OO
 | 
						|
interface. See the L<Developer|https://github.com/netdisco/netdisco/wiki/Developing>
 | 
						|
documentation for further information.
 | 
						|
 | 
						|
=head2 Plugins
 | 
						|
 | 
						|
Netdisco includes a Plugin subsystem for customizing the web user interface and backend daemon.
 | 
						|
See L<Web Plugins|https://github.com/netdisco/netdisco/wiki/Web-Plugins>
 | 
						|
and L<Backend Plugins|https://github.com/netdisco/netdisco/wiki/Backend-Plugins>
 | 
						|
for further information.
 | 
						|
 | 
						|
=head2 Extensions
 | 
						|
 | 
						|
Using the Plugins mechanism, it's also easy to write new commands (or actions)
 | 
						|
for Netdisco. For example, an action has been added to L<generate RANCID
 | 
						|
configuration|App::Netdisco::Worker::Plugin::MakeRancidConf>.
 | 
						|
 | 
						|
=head2 Developing
 | 
						|
 | 
						|
Lots of information about the architecture of this application is contained
 | 
						|
within the L<Developer|https://github.com/netdisco/netdisco/wiki/Developing> documentation.
