Apache, Tomcat, Nginx difference

1. Definition

1.Apache

Apache HTTP Server is a modular server that can run on almost any widely used computer platform. It belongs to the application server. Apache supports many modules, stable performance, Apache itself is static parsing, suitable for static HTML, pictures, etc., but can be extended scripts, modules and other support dynamic pages.

(Apche can support Phpcgiperl, but to use Java, you need Tomcat to support Apache in the background, and Java requests are forwarded to Tomcat for processing by Apache.) ）

Cons: The configuration is relatively complex and does not support dynamic pages on its own.

2. Tomcat:

Tomcat is an application (Java) server, which is just a servlet (JSP also translated into a servlet) container that can be considered an Apache extension, but can be run independently of Apache.

3. Nginx

Nginx is a very lightweight HTTP server written by the Russians, Nginx, which is pronounced "engine X", is a high-performance HTTP and reverse proxy server, but also a IMAP/POP3/SMTP proxy server.

Summarize:

Nginx Advantages: Load Balancing, reverse proxy, processing static file advantage. Nginx handles static requests faster than Apache;

Apache Advantage: Handling static files is its advantage over the Tomcat server and is fast. Apache is static parsing, suitable for static HTML, pictures and so on.

L Tomcat: Dynamic parsing of containers, processing dynamic requests, is compiled Jsp\servlet container, Nginx has a dynamic separation mechanism, static request can be directly through nginx processing, dynamic request forwarding request to the background by Tomcat processing.

Apache relative Nginx in the processing of dynamic has advantages, nginx concurrency is better, CPU memory consumption is low, if rewrite frequent, it is more suitable for Apache
