Website Dashboard

If you installed Nodeyez using the [Quick Start]({% link _install_steps/0quickstart.md %}), then this step is already done for you and you can skip ahead to using the [Nodeyez-Config]({% link _install_steps/9nodeyezconfig.md %}) tool.

Whether you are using a display screen or not, you can also make the images viewable via website dashboard. The dashboard included in nodeyez looks like this

The dashboard view will automatically cycle through the same images at 10 second intervals, showing smaller versions at the top of the screen.

Clicking on an image will automatically advance the view to the full size version of that one.

There are multiple options for setting up the dashboard. Choose the most appropriate based on your raspberry pi node

If you are currently logged in as user nodeyez, exit back to the privileged user.

Installing NGINX

Check if NGINX is installed

which nginx

If there is no returned path for NGINX, install it

sudo apt install -y nginx nginx-common

Create Self-signed Certificates

Create self-signed certificates that can be referenced in the web config.

sudo openssl req -x509 -nodes -newkey rsa:2048 -keyout /etc/ssl/private/nodeyez-nginx-selfsigned.key -out /etc/ssl/certs/nodeyez-nginx-selfsigned.crt -subj "/CN=localhost" -days 3650

Create Diffie-Hellman parameters if they don't already exist

if [ ! -f "/etc/ssl/certs/dhparam.pem" ]; then
  sudo openssl dhparam -dsaparam -out /etc/ssl/certs/dhparam.pem 4096
fi

Capture SSL Certificate Info

Capture the existing SSL Certificate and Key. This is primarily for previously existing NGINX instances. In the case of installing on a MyNodeBTC instance, the intent is to be able to use the same SSL certificate that is used for other subsites in that instance

line_ssl_certificate=$(sudo nginx -T 2>&1 | grep "ssl_certificate " | sed -n 1p)
line_ssl_certificate_key=$(sudo nginx -T 2>&1 | grep "ssl_certificate_key " | sed -n 1p)

Copy XSLT Templates

Drop in the Nodeyez XSLT Templates used for building directory listings

sudo cp /home/nodeyez/nodeyez/scripts/nginx/nodeyez*.xslt /etc/nginx/

If the above statement fails with a cannot stat error, use this

sudo cp /home/nodeyez/nodeyez/scripts/nginx/nodeyez_dirlistblack.xslt /etc/nginx/

sudo cp /home/nodeyez/nodeyez/scripts/nginx/nodeyez_imagegallery128.xslt /etc/nginx/

sudo cp /home/nodeyez/nodeyez/scripts/nginx/nodeyez_imagegallery.xslt /etc/nginx/

Copy Nodeyez SSL Config

The prebuilt SSL configuration files include references to the cert and key, common parameters, and proxy definitions.

sudo mkdir -p /etc/nginx/nodeyez
sudo cp /home/nodeyez/nodeyez/scripts/nginx/nodeyez_ssl*.conf /etc/nginx/nodeyez

Check if there were certificates in existing config

echo $line_ssl_certificate
echo $line_ssl_certificate_key

If the above outputed values, then assign back into configuration as follows

sudo rm /etc/nginx/nodeyez/nodeyez_ssl_cert_key.conf
sudo echo $line_ssl_certificate >> /etc/nginx/nodeyez/nodeyez_ssl_cert_key.conf
sudo echo $line_ssl_certificate_key >> /etc/nginx/nodeyez/nodeyez_ssl_cert_key.conf

Ensure XSLT enabled

Check for whether XSLT modules are included already

sudo cat /etc/nginx/modules-enabled/* | grep xslt

If there are no values returned, copy in the configuration to enable it

sudo cp /home/nodeyez/nodeyez/scripts/nginx/a_xslt.conf /etc/nginx/modules-enabled/a_xslt.conf

Copy Nodeyez Site

Now we deploy the site definition for the dashboard itself

MyNodeBTC Only : If you are deploying on a MyNodeBTC instance, use the following

sudo cp /home/nodeyez/nodeyez/scripts/nginx/https_nodeyez_mynode.conf /etc/nginx/sites-enabled/https_nodeyez.conf

Raspibolt Only : If you are deploying on a Raspibolt instance, use the following

sudo cp /home/nodeyez/nodeyez/scripts/nginx/http_nodeyez_raspibolt.conf /etc/nginx/nodeyez/http_nodeyez_raspibolt.conf

sudo cp /home/nodeyez/nodeyez/scripts/nginx/https_nodeyez_raspibolt.conf /etc/nginx/streams-enabled/https_nodeyez_raspibolt.conf

if [ ! -f "/etc/nginx/modules-enabled/http_nodeyez_raspibolt.conf" ]; then
  sudo ln -s /etc/nginx/nodeyez/http_nodeyez_raspibolt.conf /etc/nginx/modules-enabled/http_nodeyez_raspibolt.conf
fi

For other instances, use the following

sudo cp /home/nodeyez/nodeyez/scripts/nginx/https_nodeyez.conf /etc/nginx/sites-enabled/https_nodeyez.conf

Once complete, set the ownership

sudo chown root:root -R /etc/nginx/

Grant Group and Execute permission

This will assign group to nginx, and also give it execute permission to the group so that members can traverse the folders of nodeyez

sudo gpasswd -a www-data nodeyez
sudo chmod g+x /home/nodeyez 
sudo chmod g+x /home/nodeyez/nodeyez 
sudo chmod g+x /home/nodeyez/nodeyez/imageoutput

Configure Firewall rules

The Nodeyez website dashboard uses port 907. Enable access to view it.

sudo ufw allow 907 comment 'allow Nodeyez Dashboard HTTPS'
sudo ufw enable

You can find the IP address to access via

hostname -I

Restart NGINX

First, test the configuration

sudo nginx -t

If there are errors, review the configuration files and correct.

If you receive an error about module "ngx_http_xslt_filer_module" already being loaded, then you can remove the XSLT dropin:

sudo rm /etc/nginx/modules-enabled/a_xslt.conf

If there are no failures from testing configuration, then restart nginx

sudo systemctl restart nginx

View Dashboard

Using a web browser, see if you can access the dashboard at

https://your-node-ip:907

You can also get to lists of files in the data directory at

https://your-node-ip:907/data/

And view a specific subfolder of data as a photo album at

https://your-node-ip:907/album/
