Easy setup

wget https://raw.githubusercontent.com/nashsclay/explorer/master/setup_initial.sh
chmod +x setup_initial.sh
./setup_initial.sh

Now setup your coin and allow it to sync. Next do the following script to setup mongo

wget https://raw.githubusercontent.com/nashsclay/explorer/master/setup_mongo.sh
chmod +x setup_mongo.sh
./setup_mongo.sh

Follow the "Create Database" directions below now. Just that section. Then do the following:

wget https://raw.githubusercontent.com/nashsclay/explorer/master/setup_explorer.sh
chmod +x setup_explorer.sh
./setup_explorer.sh

Follow the "Configure" category step below now. Then edit with nano the settings.json file. When done do this script next:

wget https://raw.githubusercontent.com/nashsclay/explorer/master/setup_additional_files.sh
chmod +x setup_additional_files.sh
./setup_additional_files.sh

Next stop current wallet and re-run with tags -daemon AND -reindex. Now from here you can run these commands (one when starting and one when need to stop to make gfx and coding changes to your explorer.) These commands MUST be ran from the "explorer" folder.

nano settings.json # allows edits of the explorer
npm start
npm stop 

Double check your are FULLY synced. When done, run:

node scripts/sync.js index reindex

This command can take a number of minutes. Let it work. When done, run this command:

node scripts/sync.js index update

This command can take minutes to hours! Depends on your vps speed and size of the blockchain. Let it work. When done we need to add cron jobs to make it automatic. Scroll down till you see a section with "Crontab".

An open source block explorer written in node.js.

note: If you would like your instance mentioned here contact me

• node.js >= 0.10.28
• mongodb 2.6.x
• *coind

Enter MongoDB cli:

$ mongo

Create databse:

> use explorerdb

Create user with read/write access:

> db.createUser( { user: "iquidus", pwd: "3xp!0reR", roles: [ "readWrite" ] } )

*note: If you're using mongo shell 2.4.x, use the following to create your user:

> db.addUser( { user: "username", pwd: "password", roles: [ "readWrite"] })

git clone https://github.com/iquidus/explorer explorer

cd explorer && npm install --production

cp ./settings.json.template ./settings.json

Make required changes in settings.json

npm start

note: mongod must be running to start the explorer

As of version 1.4.0 the explorer defaults to cluster mode, forking an instance of its process to each cpu core. This results in increased performance and stability. Load balancing gets automatically taken care of and any instances that for some reason die, will be restarted automatically. For testing/development (or if you just wish to) a single instance can be launched with

node --stack-size=10000 bin/instance

To stop the cluster you can use

npm stop

sync.js (located in scripts/) is used for updating the local databases. This script must be called from the explorers root directory.

Usage: node scripts/sync.js [database] [mode]

database: (required)
index [mode] Main index: coin info/stats, transactions & addresses
market       Market data: summaries, orderbooks, trade history & chartdata

mode: (required for index database only)
update       Updates index from last sync to current block
check        checks index for (and adds) any missing transactions/addresses
reindex      Clears index then resyncs from genesis to current block

notes:
* 'current block' is the latest created block when script is executed.
* The market database only supports (& defaults to) reindex mode.
* If check mode finds missing data(ignoring new data since last sync),
  index_timeout in settings.json is set too low.

It is recommended to have this script launched via a cronjob at 1+ min intervals.

To make changes do: (note this will open a tmp file but when save will override current / add to new file)

crontab -e

Example crontab; update index every minute and market data every 2 minutes

*/1 * * * * cd /path/to/explorer && /usr/bin/nodejs scripts/sync.js index update > /dev/null 2>&1
*/2 * * * * cd /path/to/explorer && /usr/bin/nodejs scripts/sync.js market > /dev/null 2>&1
*/5 * * * * cd /path/to/explorer && /usr/bin/nodejs scripts/peers.js > /dev/null 2>&1

Iquidus Explorer is intended to be generic so it can be used with any wallet following the usual standards. The wallet must be running with atleast the following flags

-daemon -txindex

BTC: 168hdKA3fkccPtkxnX8hBrsxNubvk4udJi
JBS: JZp9893FMmrm1681bDuJBU7c6w11kyEY7D

script is already running.

If you receive this message when launching the sync script either a) a sync is currently in progress, or b) a previous sync was killed before it completed. If you are certian a sync is not in progress remove the index.pid from the tmp folder in the explorer root directory.

rm tmp/index.pid

exceeding stack size

RangeError: Maximum call stack size exceeded

Nodes default stack size may be too small to index addresses with many tx's. If you experience the above error while running sync.js the stack size needs to be increased.

To determine the default setting run

node --v8-options | grep -B0 -A1 stack_size

To run sync.js with a larger stack size launch with

node --stack-size=[SIZE] scripts/sync.js index update

Where [SIZE] is an integer higher than the default.

note: SIZE will depend on which blockchain you are using, you may need to play around a bit to find an optimal setting
