问题 I have a node app that uses CouchDB for the database and PouchDB on the client. To log in, a request is sent to the node server, which authenticates the user's credentials with the CouchDB instance, before sending a cookie back to the client.

This happens even though the AuthSession cookie is in the

Hyperledger Fabric1.4的多机部署

之前的文章 深入解析Hyperledger Fabric启动的全过程 主要讲解了Fabric的网络搭建，以及启动的整体流程，但是都是通过单机完成的。而区块链本身就是去中心化的，所以最终还是要完成Fabric网络的多机部署。在本文中，将会详细说明Fabric如何完成多机部署。 ###1 搭建环境 本文使用的是Fabric 1.4版本，搭建solo模式的4+1的架构:1Order,4Peer，数据库使用CouchDb ，所以这里需要五台机器。同时，五台机器的网络需要互通，系统使用Ubuntu16.04。 域名 ip地址 orderer.example.com 10.65.182.150 peer0.org1.example.com 10.65.26.64 peer1.org1.example.com 10.65.26.140 peer0.org2.example.com 10.65.200.182 peer1.org2.example.com 10.65.200.44 Fabric的环境搭建过程不再详解，可以参考这一篇文章 Hyperledger Fabric环境搭建过程 ##2.多机环境搭建 如果要成功搭建多机下的Fabric运行环境，首先要保证五台机子上的Fabric网络可以正常运行。 按照 Hyperledger Fabric环境搭建过程 在五台机子上搭建Fabric完成后，
