Shulou(Shulou.com)06/01 Report--

This article mainly introduces how to install Ontology blockchain browser development under Ubuntu 14.04. it has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

Warm reminder: Ontology needs to be deployed on a stand-alone machine. For more information, please see Ubuntu 14.04, Ontology development environment construction, deployment and testing.

Judging from this error, it is the Mysql password. Modify the application.properties file under the config subdirectory of the back-end directory of ontology-explorer project

Blockchain@ThinkPad-T460:~/GitClone/ontology-explorer/back-end$ vim config/application.properties

Find database.

At this point, the Ontology blockchain explorer backend configuration is complete.

Configure the Ontology blockchain explorer front end

Modify the application.properties file under the config subdirectory of the back-end folder of the ontology-explorer project, and find blockchain param

Modify the corresponding node.restful.url and save the exit.

Modify the prod.env.js file in the config subdirectory of the front-end folder of the ontology-explorer project, and the content before modification is
