nuexplorer

##Nu network Block Explorer NuExplorer is powered by MongoDB, Expressjs, Angularjs and Nodejs. Query for blocks, transactions, and addresses found in the Nu network (https://nubits.com).

###Dependencies

• Nodejs v0.10 or greater
• Mongodb 2.6
• Nu Client

###Installation

1. Download Latest Nu Wallet NuBits

• unzip,install and launch nu.exe to sync all blocks (might be a while)

2. Install Node.js
3. Install MongoDB

• a replica set is needed to keep track of changes in db.
• use mongod --replSet <name>; Note: --auth and bind_ip=127.0.0.1 are recommended configurations

4. Clone the NuExplorer repo to the server you want to deploy it on.
5. cd into directory cd ./NuExplorerOS-master
6. Load dependencies with sudo npm install.
7. Copy the mongo-oplog-watcher folder into node_modules
8. Adjust mongodb connection urls according to your mongodb setup

• connection urls are located in server.js, and /public/app/api/api.tools.js,specifically exports.db

###Setup

1. Start up the mongodb daemon. For simplicity, type mongod --replSet rs0 to spin up the daemon.

• Note this uses a replica set configuration, --replSet rs0
• The daemon will keep repeating some context telling you that it is waiting for a mongo shell connection

2. To start the mongo shell, simply type mongo in a new window pane

• Once the mongo shell opens, we have to connect to mongod --replSet rs0.
  • To do this, type rs.initiate()
  • Now, a new line should show with pointer rs0:PRIMARY>. If it doesn't,type use admin, then db.shutdownServer() and repeat step 1.

3. Now we need to create a new database in mongo shell

• for simplicity type use BlockDB

4. Now we need to create collections in BlockDB to store our data

• to do this, type db.createCollection('<CollectionName>')
  • replace <CollectionName> with the following names
  • BlockCollection
  • ChartCollection
    • after creating ChartCollection paste the following commands in the mongo shell
      • db.ChartCollection.insert({ "_id":"orphan", "orph":[] })
      • db.ChartCollection.insert({ "_id":"diff", "pos":[] })
      • db.ChartCollection.insert({ "_id":"numtrans", "Bits":[], "Shares":[]})
  • InputTxCollection
  • MotionCollection
  • OrphanBlockCollection
  • OrphanTxCollection
  • PeerCollection
  • SharesAddressCollection
  • StatusCollection
    • after creating StatusCollection paste the following commands in the mongo shell
      • db.StatusCollection.insert({_id:"statusInfo"}),
      • db.StatusCollection.insert({_id:"addressLeftOff","blockHeight":0})
  • TxCollection
  • VoteCollection

5. Double check that you have created all the collections by typing show collections in mongo shell.
6. Now, depending on what OS your running, we have to create a nu.conf file.

• if your on Windows, head to the folder C:/users/<username>/appdata/roaming/nu/
• if your on Linux, head to the folder /root/.nu/ (the same might apply to Mac OSX)
• create a file called nu.conf in the folder. (windows users can use notepad)
• now, open nu.conf and copy and paste the following into the file.

  • server=1

  • rpcport=14001

  • rpcuser=user

  • rpcpassword=pass

  • addnode=198.52.160.71

  • addnode=198.52.217.4

  • addnode=198.52.199.75

  • addnode=198.52.199.46

  • addnode=162.242.208.43

  • addnode=192.237.200.146

  • addnode=119.9.75.189

  • addnode=119.9.12.63

  • listen=1

7. Open the pythonparser folder, then locate and open NuParserv007.py in your choice of IDE

• make sure the dependencies at the top are installed on your system i.e) bitcoinrpc, pymongo, bitstring, etc.
• for bitcoinrpc, if you are using pip, use this command to install it pip install git+https://github.com/jgarzik/python-bitcoinrpc.git
• adjust line 14 according to your mongodb setup
• adjust line 30 according to your nu.conf rpcuser,rpcpassword,rpcport properties
• find the variables blk01,blk02 and according to where your nu.conf file is located, comment/uncomment the correct location i.e) for Windows use: blk01 = "C:/users/<username>/appdata/roaming/nu/blk0001.dat",blk02=...,blk=""
• now, running the script will insert the first 10 blocks into the db. Feel free to tinker with the variables fi.seek()(line 416) and START,END (lines 486,487) respectively to insert the desired blocks.

8. Feel free to take a little break at this point :) (steps 6 and 7 are optional)
9. if you want to insert the latest block discovered (make it realtime), open your nu.conf file and add this property at the bottom:

• for windows: blocknotify=C:\<python-location>\python.exe C:\<folder-location>\NuExplorerOS\pythonparser\NuParserv007.py
• for linux: blocknotify=/usr/bin/python /<folder-location>/NuExplorerOS/pythonparser/NuParserv007.py

10. now close and reopen nu.exe or nud.exe (whichever you prefer).
11. start up the server with node server.js
12. open your browser and visit localhost:800

DONE! Your setup and installation is complete. If your stuck, feel free to contact me at jgeorges371@gmail.com or write a github issue.
