Installation Process

Dependencies

The following table summarizes the tools and libraries required to run the delegates pool website.

Dependencies	Min. version	Ubuntu package
Node.js	8	install from binaries
Angular	6	install from npm
Nginx	any	nginx

If you want to run the website using SSL then you will need to install a webserver like nginx
The readme shows you how to setup the website using HTTP, since there is no sensitive data in the website

Requirements

Installing NGINX

sudo apt update && sudo apt install -y nginx

Configure NGINX

NGINX is already configured for a single website once installed.

Just edit the nginx default configuration to enable subfolder:

sudo nano /etc/nginx/sites-available/default

Change

location / {
  try_files $uri $uri/ =404;
}

to

location / {
  try_files $uri $uri/ /index.html;
}

Now, you can copy the dist folder contents to /var/www/html/ to install the website

Intalling Node.js from binaries

It is recommended to install the nodejs folder in the home directory /home/$USER/ or root directory (/root/) in a new folder

To download, go to the Node.js official release page and download the Linux Binaries. Copy it to your deisgnated folder and run these commands:

tar -xf node*.tar.xz
rm node*.tar.xz

Then add Node.js to your path:

echo -e '\nexport PATH=path_to_nodejs/bin:$PATH' >> ~/.profile && source ~/.profile

Replace path_to_nodejs/bin with the location of the bin folder where you installed Node.js

npm

Note if your installing on a root session, you need to run these additional commands before upgrading

npm config set user 0
npm config set unsafe-perm true

Update npm globally:

npm install -g npm

angular

Install the latest version of Angular globally:

npm install -g @angular/cli@latest

Then install the compressor UglifyJS globally :

npm install -g uglify-js

Develop

Clone repository

In your desired folder, clone the repository:

git clone https://github.com/X-CASH-official/delegates-supervisor.git

Enable port 80 in the firewall

Uncomment these lines in $HOME/firewall_script.sh

# iptables -t filter -I INPUT -p tcp --syn --dport 80 -m connlimit --connlimit-above 100 --connlimit-mask 32 -j DROP

# iptables -A INPUT -p tcp --dport 80 -j ACCEPT

Run the firewall script
$HOME/firewall_script.sh

Configure

Add your node wallet public address for the API calls:

nano delegates-supervisor/src/app/services/public_address.service.ts

Edit Line 7:

PUBLIC_ADDRESS:string = ""

to

PUBLIC_ADDRESS:string = "<YOUR_NODE_WALLET_PUBLIC_ADDRESS>"

Build

To build the delegates pool website, go to the delegates-supervisor folder and run:

npm run build

It will build in the distfolder.

Compress the .js files with Uglify-JS and move all of the contents of this folder to your xcash-dpops/ folder

cd dist
for f in *.js; do echo "Processing $f file.."; uglifyjs $f --compress --mangle --output "{$f}min"; rm $f; mv "{$f}min" $f; done
cd ../

Copy the dist folders contents to the default nginx setup
cp -a dist/* /var/www/html/

Testing

npm test

To test that you have properly configured the delegates pool website, run xcash-dpops with the --test_data_add flag. This will add test datas to the MongoDB.

Now run the website server again using the normal options.

Next, navigate to your servers IP address or website domain. You should now see the website and some test data. You can navigate through the website using the test data.

When you have verified that the website works correctly, remove the test data by shutting down the xcash-dpops and then running it again with the --test_data_remove flag.

Installation Process LXC

Dependencies

The following table summarizes the tools and libraries required to run the delegates explorer.

Dependencies	Min. version	Ubuntu package
Node.js	8	install from binaries
Angular	6	install from npm
nginx	latest version	install from script

Requirements

Update LXD

LXD is a Linux Container system manager. Learn more here

You can install and update the website in a LXD/LXC container using the xcash-dpops auto-installer.

Check if LXD is installed:

lxd --version

If it displays a version, it is recommneded to uninstall it to update it manually. Run:

sudo apt remove -y --purge lxd lxd-client

Then reinstall the latest version:

sudo snap install lxd

Run the configuration for LXD and set the default selection to the configuration questions:

lxd init

For the size of the new loop device specify 80-90% of your disk space. Your containers won't have an artifical low disk space limit.

Install from script

Run the autoinstaller.sh to install the website into a LXC/LXD container:

bash -c "$(curl -sSL https://raw.githubusercontent.com/X-CASH-official/delegates-supervisor/master/scripts/autoinstaller.sh)"

The website will be started in the LXC container.

Container commands

# Start the container  
lxc start container

# Stop the container  
lxc stop container

# Delete the container (The container must be stopped first)  
lxc delete container

# Open a terminal inside the container  
lxc exec container -- bash

# Exit the terminal  
exit

# List all running containers  
lxc list

Configure the container

You need to setup port forwarding on the container to route all traffic on port 80 to the container.

Check the containers private IPV4 address:

lxc list

Then forward the ports to the containers private IP address:

lxc config device add delegates-supervisor delegates-supervisor-80 proxy listen=tcp:PUBLIC_IP_OF_SERVER:80 connect=tcp:PRIVATE_IP_OF_CONTAINER:80

Remove proxy

lxc config device remove delegates-supervisor delegates-supervisor-80

Update Process

Run the autoinstaller.sh on the host and choose the update mode:

bash -c "$(curl -sSL https://raw.githubusercontent.com/X-CASH-official/delegates-supervisor/master/scripts/autoinstaller.sh)"

Testing

npm test
