Mongodb Auth setting.

Configure MongoDB

In view of system security, most of mongoDB Admin has setup security options, So, You need to setup mongodb auth informations. Switch to the built-in admin database:

$ mongo
$ > use admin

  1. Create an administrative user (if you have already admin or root of mongodb account, then skip it)

# make admin auth and role setup
$ > db.createUser( { user: "admin", pwd: "", roles: ["root"] } )

And, You can make Explorer's "explorerDB" database with db user accounts "explorer" and password "some_pass_code".

$ > use explorerDB
$ > db.createUser( { user: "explorer", pwd: "", roles: ["dbOwner"] } )
$ > quit()

Above dbuser explorer will full access explorerDB and clustor setting will be well used on monitoring the multiple sharding and replication of multiple mongodb instances. Enable database authorization in the MongoDB configuration file /etc/mongodb.conf by appending the following lines:

auth=true

Restart MongoDB and verify the administrative user created earlier can connect:

$ sudo service mongodb restart
$ mongo -u admin -p your_password --authenticationDatabase=admin

If everything is configured correctly the Mongo Shell will connect and

$ > show dbs

will show db informations. and You can add modified from ./db.js:148 lines, add auth information and mongodb connect options.

mongoose.connect(process.env.MONGO_URI || 'mongodb://localhost/explorerDB', {
  useMongoClient: true
  // poolSize: 5,
  // rs_name: 'myReplicaSetName',
  // user: 'explorer',
  // pass: 'yourdbpasscode'
});

And explore it.

Run

The below will start both the web-gui and sync.js (which populates MongoDB with blocks/transactions).

npm start

You can leave sync.js running without app.js and it will sync and grab blocks based on config.json parameters

npm run sync

Enabling stats requires running a separate process:

npm run stats

Enabling richlist requires running a separate process:

npm run rich

You can configure intervals (how often a new data point is pulled) and range (how many blocks to go back) with the following:

RESCAN=100:7700000 node tools/stats.js (New data point every 100 blocks. Go back 7,700,000 blocks).

Docker installation

Set nodeAddr in config.json to host.docker.internal

Run docker-compose up
