忧郁者

　　0. Introduction
　　[ Tomcat ] : Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies. (http://tomcat.apache.org/)
　　1. Environment
　　Ubuntu 10.04
　　JDK 1.6.0 u27
　　Apache Tomcat 7.0.22
　　2. Steps
　　2.0 Install JDK and Tomcat
　　2.1 All of the configuration files are in the "{$CATALINA_HOME}/conf" folder, and "server.xml" is the core configuration file, the following is the structure of "server.xml"
<Server>
  <Listener/>
  <Listener/>
  <GlobalNamingResources>
    <Resource/>
  </GlobalNamingResources>
  <Service>
    <Connector/>
    <Connector/>
    <Engine>
      <Realm>
        <Realm/>
      </Realm>
      <Host>
        <Valve/>
      </Host>
    </Engine>
  </Service>
</Server>
　　2.2 Change the port number if necessary, change the port="8080" to port="80" or some other number you like
    <Connector port="8080" protocol="HTTP/1.1"  
               connectionTimeout="20000"  
               redirectPort="8443" />
　　2.3 Configure virtual directory
2.3.1 Copy folder "{$CATALINA_HOME}/webapps/ROOT/WEB-INF" to your site directory
because the /WEB-INF/web.xml is needed for every web sites, you can code it yourself, but it is recommended to copy it (my site directory is /home/yineng/workspace/tomcatwebsite in this article)
2.3.2 Add a index.jsp file to your web site directory which can only content "hello, world"
2.3.3 Edit "{$CATALINA_HOME}/conf/server.xml"
add <Context path="/myweb" docBase="/home/yineng/workspace/tomcatwebsite"/> before </Host>
path : the web browser path, must start with "/"
docBase : absolute disk path of your web site
2.3.4 Now view http://localhost:8080/myweb/ in your browser
　　2.4 If you want your web site page list the folders and files in the directory user visited, you can edit "{$CATALINA_HOME}/conf/web.xml" like the following, but it is intensely recommend to close listing function when you release the web site
change <param-value>false</param-value> to <param-value>true</param-value>
        <init-param>
            <param-name>listings</param-name>
            <param-value>false</param-value>
        </init-param>
　　2.5 You may need to shut down and start up the tomcat server several times to see the effect when you configure it
$ ./{$CATALINA_HOME}/bin/shutdown.sh
$ ./{$CATALINA_HOME}/bin/startup.sh
　　2.6 OK, now your first web site has been deployed
3. Additional Introduction
　　3.1 /WEB-INF/web.xml
/WEB-INF/web.xml- The Web Application Deployment Descriptor for your application. This is an XML file describing the servlets and other components that make upyour application, along with any initialization parameters and container-managed security constraints that you want the server to enforce for you. This file is discussed in more detail in the following subsection.
