README
Diquidus Explorer - 1.6.9.1
================
An open source block explorer written in node.js based off original iquidus and ciquidus explorers.
Diquidus features sendrawtx API and UTXO APIs as well as masternode counts. CoinExchange and TradeOgre market APIs available.
### Requires
* node.js >= 0.10.28
* mongodb 2.6.x
* libzmq-dev
* libkrb5-dev
* *coind
### Create database
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"] })
### Get the source
git clone https://github.com/carsenk/diquidus-explorer explorer
### Install deps
sudo apt-get install build-essential pkg-config libzmq-dev libkrb5-dev
### Install node modules
cd explorer && npm install --production
### Configure
cp ./settings.json.template ./settings.json
*Make required changes in settings.json*
### Start Explorer
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
### Syncing databases with the blockchain
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.*
**crontab**
*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
### Wallet
Diquidus 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
### Known Issues
**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*
