Postgresql 在多台主机上虚拟化hyperledger网络时出现问题

我已经完成了教程

我连接了3台主机，所有服务都启动了。我在PC2主机中运行./script.sh时得到了正确的结果。 现在，我将学习下一个教程：

有人能在本教程中给我一些启发吗？我想我应该用ubuntu 16.04创建一个新主机，并安装以下必备组件：

nodejs 8.11.x

PostgreSQL 9.5或更高版本

Jq

我说得对吗

在exploreconfig.json中，我更新了postgres变量：

主机：192.168.1.136（第四代虚拟机ip）， 港口：5432， 用户名：postgres， 密码：psql， 数据库：fabric

他们说得对吗

我还修改了config.json文件中的order、Org1[peer0&peer1）、Org2（peer0&peer1）IP地址，以及网络启动并运行的前三个虚拟机的IP地址

并遵循其余说明和测试，但当我运行命令./start.sh时，控制台中有以下日志：

false 'ssl-certs' '/home/database/blockchain-explorer/ssl-certs'

我可以给你一些方面来检查你的环境


首先，您需要检查是否能够从尝试启动Hyperledger Explorer的虚拟机访问postgresql DB（第四个虚拟机）。如果不能，您需要更改postgres配置（postgresql.conf/pg_hba.conf），以便启用外部访问

$sudo-u postgres psql-h 192.168.1.136-d fabric-c“表对等”

其次，请确认您确实在第四个VM上运行了./createdb.sh。如果更改了数据库名称，还需要对齐脚本

$cd-app/persistence/fabric/postgreSQL/db/

$./createdb.sh
