Tomcat是否需要Apache httpd？

Question

If I am given a war file that contains a Java web application, and I want to run that war locally, then do I just need Tomcat, or do I need Tomcat and Apache httpd (or any other web server)? Thanks in advance!

Answer 1

Tomcat is a web server of its own, so a separate web server like Apache is not required. You probably will want to change Tomcat's port though, since it defaults to 8080 and web sites are usually on port 80.

I think people generally put Apache in front of Tomcat so they can do things like:

• Have one website have several Tomcat instances behind it.
• Serve static files from Apache to take load off of Tomcat.
• Use other Apache features you may need (modules).
• As @TacticalCoder mentions in the comments, you need to be root to listen on port 80, so some people may be using Apache as an easy way to proxy port 80 to port 8080.

I'd recommend the YAGNI approach and just go with Tomcat until/unless you find a reason you want Apache in front of it.

Answer 2

Just Tomcat. HTTPD is never a requirement for Tomcat.

Answer 3

Tomcat是一个servlet容器，它有自己的http服务器，所以如果你想运行一个war，你只需要一个tomcat，但如果你想运行一个只包含静态文件（html，js，css）的网站，你应该选择apache更好，即使tomcat可以做到这一点

Answer 4

您只需要Tomcat或任何其他Java servlet容器（Jetty，resin等）。
