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。

安装tomcat

//安装依赖包
[root@localhost ~]# yum -y install java-11-openjdk-devel java-11-openjdk

//解压安装包
[root@localhost ~]# tar xf apache-tomcat-9.0.46.tar.gz
[root@localhost ~]# ls
anaconda-ks.cfg apache-tomcat-9.0.46 apache-tomcat-9.0.46.tar.gz scripts

//移动到/usr/local/tomcat下
[root@localhost ~]# mv apache-tomcat-9.0.46 /usr/local/tomcat

//启动tomcat
[root@localhost tomcat]# /usr/local/tomcat/bin/startup.sh

配置管理界面Manager App

[root@localhost conf]# vim tomcat-users.xml
//把下列两行加到这个配置文件的倒数第二行
<role rolename=\”manager-gui\”/>
<user username=\”tomcat\” password=\”s3cret\” roles=\”manager-gui\”/>

[root@localhost tomcat]# ls
bin conf lib logs README.md RUNNING.txt webapps
BUILDING.txt CONTRIBUTING.md LICENSE NOTICE RELEASE-NOTES temp work
[root@localhost tomcat]# cd webapps/
[root@localhost webapps]# ls
docs examples host-manager manager ROOT
[root@localhost webapps]# cd manager/
[root@localhost manager]# ls
css images index.jsp META-INF status.xsd WEB-INF xform.xsl
[root@localhost manager]# cd META-INF/
[root@localhost META-INF]# ls
context.xml
[root@localhost META-INF]# vim context.xml
allow=\”192\\.168\\.100\\.\\d+|127\\.\\d+\\.\\d+\\.\\d+|::1|0:0:0:0:0:0:0:1\” />
在这个文件中加入要访问的ip网段。

配置Host Manager

[root@localhost conf]# ls
Catalina context.xml logging.properties tomcat-users.xsd
catalina.policy jaspic-providers.xml server.xml web.xml
catalina.properties jaspic-providers.xsd tomcat-users.xml
[root@localhost conf]# vim tomcat-users.xml
<role rolename=\”manager-gui\”/>
<role rolename=\”admin-gui\”/> //在配置文件中加入此行
<user username=\”zdj\” password=\”123456\” roles=\”manager-gui,admin-gui\”/> //加入admin-gui

因为修改了配置文件，，这里需要重启
