example, if you create a web app and deploy it to Tomcat (multi-application), the default rule is to add a prefix to the project name in the URI to access it. For example, we assume that the project is named shopping, giving it a separate domain name: shopping.website.com. Then the default URL needs shopping.website.com/shopping to be OK, now it needs to be set to shopping.website.com. How to use Nginx configuration, to achieve our goal? In the nginx.conf configuration, add the rewr

Because the cluster involves Server Load balancer processing and requests need to be distributed among different machines, domain name resolution is required. In addition, machines in the cluster need to share the site configurati
