The following document is a step-by-step guide to run BWS in cluster mode. Configuration for all required modules can be specified in https://github.com/bitpay/bitcore-wallet-service/blob/master/config.js ###Install BWS ```bash npm install bws cd bws ```` ###Start MongoDB Example configuration for connecting to the MongoDB instance: ```javascript storageOpts: { mongoDb: { uri: 'mongodb://localhost:27017/bws', }, } ``` ###Start Locker server ```bash node locker/locker.js ```` Example configuration for connecting to locker server: ```javascript lockOpts: { lockerServer: { host: 'localhost', port: 3231, }, } ``` ###Start message broker server ```bash node messagebroker/messagebroker.js ```` Example configuration for connecting to message broker server: ```javascript messageBrokerOpts: { messageBrokerServer: { url: 'http://localhost:3380', }, } ``` ###Configure blockchain service Note: this service will be used by blockchain monitor service as well as by BWS itself. An example of this configuration is: ```javascript blockchainExplorerOpts: { livenet: { provider: 'insight', url: 'https://insight.bitpay.com:443', }, testnet: { provider: 'insight', url: 'https://test-insight.bitpay.com:443', }, } ``` ###Start blockchain monitor service The monitor service is used to notify instances of BWS of incoming txs. It will connect to all previous services so it is important that those are already running. ```bash node bcmonitor/bcmonitor.js ```` ###Start email service ```bash node emailservice/emailservice.js ```` Example configuration for connecting to email service (using postfix): ```javascript emailOpts: { host: 'localhost', port: 25, ignoreTLS: true, subjectPrefix: '[Wallet Service]', from: 'wallet-service@bitcore.io', } ``` ###Enable clustering Change `config.js` file to enable and configure clustering: ```javascript { cluster: true, clusterInstances: 4, } ``` ###Start bws instances ```bash npm start ````
