App::Netdisco::Manual::Deployment - Tips and Tricks for Deployment
Relocating the Installation
The installation process installs Netdisco self-contained to your home directory. The target directory can easily be changed by setting the NETDISCO_HOME
environment variable, for example:
export NETDISCO_HOME=/opt/netdisco
Obviously, you'll need to substitute this wherever you see "~
" in the installation instructions. The Netdisco application will use this setting itself to locate files and configuration.
Pass Options to the Web Frontend Daemon
Simply add any options after the "start
" command. See other sections of this document for some examples.
Non-root Hosting
Netdisco will assume its web site is hosted at the apex of your server - that is, the document root. To relocate the web application, pass the --path
parameter to the web startup script:
~/bin/netdisco-web start --path=/netdisco2
Alternatively, can set the path
configuration option in your deployment.yml
file:
path: '/netdisco2'
Listening Port for the Web Frontend
Pass the --port
parameter to any of the web scripts. For example:
~/bin/netdisco-web start --port=8080
Listening Address for the Web Frontend
Pass the --listen
parameter to any of the web scripts. Note that you always must include the port number. For example:
~/bin/netdisco-web start --listen=127.0.0.1:8080
Behind a Proxy
By default the web application daemon starts listening on port 5000 and goes into the background. This is ideal for hosting behind a web proxy (e.g. Apache with mod_proxy
).
After enabling the headers
, proxy
and proxy_http
modules in Apache, a suitable configuration would be:
ProxyPreserveHost On
ProxyPass / http://localhost:5000/ retry=0 timeout=5
ProxyPassReverse / http://localhost:5000/
ProxyRequests Off
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
To combine this with Non-root Hosting as above, simply change the paths referenced in the configuration, and set path
in your deployment.yml
as discussed above. Note there is no trailing slash in the Apache config:
ProxyPass /netdisco2 http://localhost:5000/netdisco2 retry=0 timeout=5
ProxyPassReverse /netdisco2 http://localhost:5000/netdisco2
To delegate user authentication to Apache, use the trust_remote_user
or trust_x_remote_user
settings. See App::Netdisco::Manual::Configuration for more details.
SSL Support
There is no SSL support in the built-in web server. This is because it's not straightforward to support all the SSL options, and using port 443 requires root privilege, which the Netdisco application should not have.
You are instead recommended to run netdisco-web
behind a reverse proxy as described elsewhere in this document. Apache can easily act as an SSL reverse proxy.
SQL and HTTP Trace
For SQL debugging try the following commands:
DBIC_TRACE_PROFILE=console DBIC_TRACE=1 ~/bin/localenv starman ~/bin/netdisco-web-fg --workers=1 --disable-keepalive
DBIC_TRACE_PROFILE=console DBIC_TRACE=1 ~/bin/localenv ~/bin/netdisco-daemon-fg

Other ways to run and host the web application can be found in the Dancer::Deployment page. See also the plackup and starman documentation.
