Configuration of Tomcat's Server.xml virtual host and virtual directory

Previously developed Java EE sites are arranged under Tomcat, the layout directory is generally $catalina_home/webapps/webname, so to visit the site, then in HTTP// After localhost, the context path (ContextPath)/webname must be added, while the run environment is generally http://www.abc.com and the context path is empty. This creates the difference between the development environment and the operating environment, although the JSP can be solved by <%=request.getcontextpath ()%>, but if you change to another template, such as velocity, it will not work.

This article through the reference to the practice of the major netizens and their own hands-on practice, successfully set up a number of virtual host and virtual directories under Tomcat, write out for the reference of all users and make a note for themselves.

The configuration files for Tomcat 5 and Tomcat 6 are: $CATALINA _home/conf/server.xml, other versions of the Tomcat configuration file are not used.

Note the following one, two, ... The steps are not sequential and can be selected.

Description: Virtual Host in Server.xml is host, virtual directory is context.

First, modify the port
Tomcat Default Web port is 8080, I generally like to change it to 80, of course, it is completely unnecessary
<connector port= "protocol=" http/1.1 "connectiontimeout=" 20000 "redirectport=" 8443 "/>
Note that the HTTP protocol is modified, that is, the protocol= "http/1.1", not the other.

Second, increase the virtual directory
1, the simplest way: directly put the Java EE site in the $catalina_home/webapps directory, and then through the Http://localhost/WebName,WebName for the site directory name;

2, Custom: Put the site in other directories, such as in the/var/www/webapp directory, then you need to modify the Server.xml.
Add the following to </Host> before you:
<context path= "/springmvc" docbase= "/var/www/webapp/springmvc" workdir= "/var/www/webtmp/springmvc" debug= "5" Reloadable= "false" crosscontext= "true"/>
can be accessed through Http://localhost/SpringMVC, that is, the host name of localhost added a virtual directory named Springmvc, of course, the name here is entirely personal-dependent.

Third, increase the virtual host
In fact, this is the focus of this article, that is, the case at the beginning of this article. Each of us develop a Web site, are accessed through the form of http://localhost/WebName, is not very troublesome?

1. Modify the Hosts file to increase the host name
(1) The Hosts file for the Linux system is/etc/hosts
(2) The Hosts file for the WINDOWS system is C:\WINDOWS\system32\drivers\etc\hosts
For example, if you want to increase the www.local.com host, add a line to this file: 127.0.0.1 www.local.com, which means that when you visit www.local.com, you actually access 127.0.0.1;
I prefer a short domain name, so I added: 127.0.0.1 springmvc

2. Modify the configuration file
Add a Host node after </Host>:
That is, the addition of a virtual host named Springmvc, of course, it can also be name= "www.local.com", depending on the specific circumstances.
In this way, the IP access is: Http://SpringMVC.

3. Directory Settings
Host SPRINGMVC Web files are all placed in the/VAR/WWW/WEBAPP/SPRINGMVC directory, add the root directory under this directory, put into your Java EE website project, so that you can access your site through Http://SpringMVC , there is less/springmvc this string, on the IP and the operating environment to maintain the same.

Iv. Other issues

(1)

The SPRINGMVC website is accessed through Http://SpringMVC;
The website that is accessed by http://localhost is Tomcat's own;
We already know in the hosts file that the IP corresponding to both SPRINGMVC and localhost is: 127.0.0.1
So, what was the site that was accessed through http://127.0.0.1?

The parent node in host is: <engine name= "Catalina" defaulthost= "Springmvc" >
As can be seen from the above, defaulthost= "Springmvc" determines which site 127.0.0.1 visits, and my settings are Access Springmvc

<?xml version= "1.0" encoding= "Utf-8"?>

</Server>

First, modify the $tomcat/conf/server.xml file.
In the Server.xml file, there is a section as follows:
XML code

<engine name= "Catalina" defaulthost= "localhost to your domain" >

To add between XML code <context path= "" docbase= "myjsp" debug= "0" reloadable= "true"/>
Path is the name of the virtual directory, if you want to enter only the IP address to display the home page, the key value is left blank;
Docbase is the path to the default directory, it defaults to the $tomcat/webapps/root directory, and now I have a myjsp directory in the WebApps directory, which is the default directory for my directory.
Debug and reloadable are generally set to 0 and true respectively.
