Node and Iquidus Explorer Setup for Dummies

Node / Iquidus Explorer Setup for Dummies
Pulse Crypto is used in this example.

This Tutorial is going to create a Daemon (node) and install Explorer.
THIS IS NOT GOING TO CREATE A GUI CLIENT.

Follow the instructions in [whatever coin name] docs folder Unix build - some builds are different.

I setup this up on both Ubuntu 15.10 and 16.04 with no issues.

*** Change Password / Update System
******************************************

Change passwords
# sudo passwd  //change root password

Update Packages
# sudo apt-get update
# sudo apt-get upgrade -y

Install git and nano
# sudo apt-get install nano git -y

******************************************
*** Installing Pulse Node
******************************************

Get the Source Code

Basic packages to build the coin
# sudo apt-get install build-essential libssl-dev libdb++-dev libboost-all-dev libqrencode-dev miniupnpc libminiupnpc-dev autoconf pkg-config libtool autotools-dev libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev automake -y

Create a Swap File - Low Ram Servers
# sudo fallocate -l 4G /swapfile
# sudo chmod 600 /swapfile
# sudo mkswap /swapfile
# sudo swapon /swapfile
# sudo nano /etc/fstab

Add to fstab file
/swapfile   none    swap    sw    0   0

Adding the Coin
# sudo git clone https://github.com/elcrypto/Pulse.git

Change Directories to src/
# cd Pulse/src/ 

Compile the code with flags
# sudo make -f makefile.unix USE_UPNP=1
# sudo strip pulsed

Stat the file with daemon flag so that you can create a config file
# sudo ./pulsed -daemon

Create a conf file in .pulse/pulse.conf
# cd
# sudo nano .pulse/pulse.conf

rpcuser=pulserpc
rpcpassword=Gnfh67gdmRTGvA5YB3UZhV6e6cPTTeneTTdnosLLD3cU
listen=1
maxconnections=500

*make sure to set the file to read only.
# sudo chmod 400 .pulse/pulse.conf
# cd Pulse/src
# sudo ./pulsed -daemon -txindex

Check it daemon has started.  If it returns information, the daemon is working!
# sudo ./pulsed getinfo

Stopping the daemon
# sudo ./pulsed stop

Install MongoDB Community Edition

# sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
# echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
# sudo apt-get update
# sudo apt-get install -y mongodb-org

# Reboot your system
# sudo reboot
# sudo service mongod start

Running MongoDB - reference
# sudo service mongod start
# sudo service mongod stop
# sudo service mongod restart

Installing Nodejs
# sudo apt-get update
# sudo apt-get install nodejs nodejs-legacy -y
# sudo apt-get install npm -y

Creating a MongoDB Database
# sudo mongo
> use explorerdb
> db.createUser( { user: "3er22wee3", pwd: "4y2#1iuu34hbbw2", roles: [ "readWrite" ] } )
> exit

Installing the Explorer
# cd /home/
# git clone https://github.com/iquidus/explorer explorer
# cd explorer && npm install --production
# cp ./settings.json.template ./settings.json

Modify the Settings File
# sudo nano settings.json

See if it's working
# npm start

Update the databases
# sudo node scripts/sync.js index update 

Install Forever to keep the js running
# sudo npm install forever -g
# sudo npm install forever-monitor

Start the Explorer
# forever start bin/cluster

******************************************
*** Installing Cron
*** https://help.ubuntu.com/community/CronHowto
******************************************

# sudo apt-get install gnome-schedule -y

Editing Cron
# sudo crontab -e

Add Cron to File to update the explorer
*/1 * * * * cd /path/to/explorer && /usr/bin/nodejs scripts/sync.js index update > /dev/null 2>&1

Add Cron to make sure the Pulsed runs (NOT WORKING)
If anyone has a good reboot for this, please post in the comments.
@reboot cd /root/Pulse/src ./pulsed -daemon -txindex
@reboot cd /root/explorer forever start bin/cluster
