Consolidating Apache Http server and Tomcat can improve processing performance for static files, load balancing with WEB servers, and fault-tolerant, seamless upgrade applications. This article describes three ways to integrate Apache and Tomcat.
Let's start by introducing why we want to connect Apache with Tomcat. In fact, Tomcat itself has provided the HTTP service, the default port of the service is 8080, after the installation of Tomcat through the 8080 port can be directly used by Tomcat running applications, you can also change the port to 80.
Now that Tomcat itself can provide such a service, why should we introduce Apache or some other specialized HTTP server? There are several reasons:
1. Improve the processing performance of static files
2. Using a WEB server for load balancing and fault tolerance
3. Seamless upgrade of applications
