Servlet container: named catalina, used to process Servlet code

JSP container: translating JSP dynamic web pages into Servlet code

Tomca deployment steps (simple)

1. Download and install jdk

two。 Install and start Tomcat

3. Configure virtual host

Create a Tomcat virtual host

​ Tomcat server, which allows users to configure multiple Web sites on the same computer, in which case, you need to configure a different hostname, that is, a virtual host, for each Web site. In real life, in order to improve the utilization of hardware resources, many websites realize the sharing of servers by configuring virtual hosts.
