Lisk Explorer version 1.2.0 works in conjunction with the Lisk Core API. It uses Redis for caching data and Freegeoip to parse IP geo-location data.
These programs and resources are required to install and run Lisk Explorer
-
Nodejs v6.10.1 or higher (https://nodejs.org/) -- Nodejs serves as the underlying engine for code execution.
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - sudo apt-get install -y nodejs -
Redis (http://redis.io) -- Redis is used for caching parsed exchange data.
sudo apt-get install -y redis-server -
Freegeoip (https://github.com/fiorix/freegeoip) -- Freegeoip is used by the Network Monitor for IP address geo-location.
wget https://github.com/fiorix/freegeoip/releases/download/v3.1.5/freegeoip-3.1.5-linux-amd64.tar.gz tar -zxf freegeoip-3.1.5-linux-amd64.tar.gz ln -s freegeoip-3.1.5-linux-amd64 freegeoip nohup ./freegeoip/freegeoip > ./freegeoip/freegeoip.log 2>&1 & -
Grunt.js (http://gruntjs.com/) -- Grunt is used to run eslint and unit tests.
sudo npm install -g grunt -
PM2 (https://github.com/Unitech/pm2) -- PM2 manages the node process for Lisk Explorer and handles log rotation (Highly Recommended)
sudo npm install -g pm2 -
PM2-logrotate (https://github.com/pm2-hive/pm2-logrotate) -- Manages PM2 logs
pm2 install pm2-logrotate pm2 set pm2-logrotate:max_size 100M -
Git (https://github.com/git/git) -- Used for cloning and updating Lisk Explorer
sudo apt-get install -y git -
Tool chain components -- Used for compiling dependencies
sudo apt-get install -y python build-essential automake autoconf libtool
Clone the Lisk Explorer Repository:
git clone https://github.com/LiskHQ/lisk-explorer.git
cd lisk-explorer
npm install
The frontend is using Webpack to create core bundles for Lisk Explorer.
For having a watcher to generate bundles continuously for all the changes of the code, Run the following command:
npm run start
And for generating the minified bundles in production environment run:
npm run build
Candlestick data needs to be initialized prior to starting Lisk Explorer. During runtime candlestick data is updated automatically.
To build candlestick data for each exchange run:
grunt candles:build
To update candlestick data manually run after initialization:
grunt candles:update
The default config.js file contains all of the configuration settings for Lisk Explorer. These options can be modified according to comments included in configuration file.
To enable Top Accounts functionality, edit your Lisk Client config.json (not the explorer):
{
"port": 8000,
"address": "0.0.0.0",
"version": "0.5.0",
"minVersion": "~0.5.0",
"fileLogLevel": "info",
"logFileName": "logs/lisk.log",
"consoleLogLevel": "info",
"trustProxy": false,
"topAccounts": false, <--- This line needs to be changed to read true
After the change is made the Lisk Client will need to be restarted. (Example):
bash /PATH_TO_LISK_DIR/lisk.sh reload
To test that Lisk Explorer is configured correctly, run the following command:
node app.js
Open: http://localhost:6040, or if its running on a remote system, switch localhost for the external IP Address of the machine.
Once the process is verified as running correctly, CTRL+C and start the process with PM2. This will fork the process into the background and automatically recover the process if it fails.
pm2 start pm2-explorer.json
After the process is started its runtime status and log location can be found by issuing this statement:
pm2 list
To stop Explorer after it has been started with PM2, issue the following command:
pm2 stop lisk-explorer
Before running any tests, please ensure Lisk Explorer and Lisk Client are configured to run on the Lisk Testnet.
Replace config.js with config.test file from the test directory:
cp test/config.test ./config.js
Replace the config.json for the Lisk Client the corresponding file under the test directory:
cp test/config_lisk.json /PATH_TO_LISK_DIR/config.json
Then restart the Lisk Client (example):
bash /PATH_TO_LISK_DIR/lisk.sh reload
Launch Lisk Explorer (runs on port 6040):
pm2 start pm2-explorer.json
Run the test suite:
npm test
Run individual tests:
npm test -- test/api/accounts.js
npm test -- test/api/transactions.js
