前言
Tomcat 是一款开源的 Java Servlet 实现，简单来说就是一个 java 应用解析容器
The Apache Tomcat® software is an open source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies
常与 Apache 一起配合实现 WebApp, Apache 提供静态内容的服务，Tomcat 提供动态内容的服务
CMDBuild 也是通过 Tomcat 来提供 WEB 服务, 在研究 CMDBuild 之前，需要对 Tomcat 进行简单的了解
Tomcat 依赖 java 运行环境，所以正常运行前的提是需要有相应版本的 JDK
这里分享一下 Tomcat 的安装方法
Tip: 当前的版本为 9.0.5 , 但是在此演示的版本为 8.5.28, 原因为 CMDBuild 官方推荐此版本，为了考虑兼容性，就没有使用最新的版本
