Requirement: the same Tomcat
Objectives:
1. Access the project under the webapp of Tomcat through the localhost / project name 2. Through www.aaa.com and www.bbb.com, visit the virtual hosts with different domain names under Tomcat
I. modify the port number under the server.xml file
II. Project location
3. Multi domain configuration
Copy and paste the information in the server. XML file into the label, and modify it as follows. The parameter name defaults to localhost, changes to your own domain name and adds a label between the labels, and the parameter path is your project ROOT directory. For example, if the project is empty directly under the tomcat, docBase is based on the appBase, and you can write the absolute path or the relative path , you can put the project in the ROOT folder, so that the address does not have the project name
In fact, the context tag only serves as a connection. It's ok if you don't use it. Just put the content of the project (i.e. the project name folder excluding the outer layer) directly under the ROOT to run. The effect is the same

IV. domain name resolution
Since you didn't buy a domain name, you can only use the stand-alone version by modifying the hosts file Hosts path: C:\Windows\System32\Drivers\etc\hosts
V. make domain name resolution effective
Restart or run ipconfig /flushdns with cmd command
Six, test
