1. tomcat简介Tomcat是Apache 软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun 和其他一些公司及个人共同开发而成。由于有了Sun 的参与和支持，最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现，Tomcat 5支持最新的Servlet 2.4 和JSP 2.0 规范。因为Tomcat 技术先进、性能稳定，而且免费，因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可，成为目前比较流行的Web 应用服务器。
Tomcat 服务器是一个免费的开放源代码的Web 应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。对于一个初学者来说，可以这样认为，当在一台机器上配置好Apache 服务器，可利用它响应HTML（标准通用标记语言下的一个应用）页面的访问请求。实际上Tomcat是Apache 服务器的扩展，但运行时它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的。
诀窍是，当配置正确时，Apache 为HTML页面服务，而Tomcat 实际上运行JSP 页面和Servlet。另外，Tomcat和IIS等Web服务器一样，具有处理HTML页面的功能，另外它还是一个Servlet和JSP容器，独立的Servlet容器是Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Apache服务器。目前Tomcat最新版本为9.0。
tomcat就是传说中的中间件之一，tomcat本身是一个容器，专门用来运行java程序，java语言开发的网页.jsp就应该运行于tomcat中。而tomcat本身的运行也依赖于jdk环境。

以部署两个项目为例：
//关闭防火墙
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# vim /etc/selinux/config
**//将第六行中的 enforcing 改为 disabled**
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@localhost ~]# setenforce 0
//安装之前请确保本地仓库可用
//安装jdk环境
[root@localhost ~]# yum -y install java-1.8.0*
