Web application-Configure a virtual host (build a Web site) __web

Recently learned some new technology, is about the web development, is how to configure the virtual host, that is how to build a Web site.

Download and install the Tomcat server first, then store your own Web application on your own computer, for example, by writing an HTML file: index.html. The storage path is d:\sina\mail\index.html, and the contents of the file are, of course, casually written.

Then start configuring the virtual host;

Here's what you need to say about the directory structure of the Tomcat server (as shown in the figure):

And the directory where the Web application resides:

For example, we want to create a virtual host for the Web application we just created, as follows: Open the Tomcat server directory conf, open the Server.xml file, there is a host tag inside, we add a host tag inside:

      
 
If you have just started a Tomcat server, you will need to reboot the server after you have changed the Server.xml file. In addition, we need to make some settings on our own computers.    Open path C:\Windows\System32\drivers\etc; Inside there is a Hosts file, open and then for example after adding a host name and its own computer IP address mapping such as: 192.168.1.53 www.sina.com.cn;

Then enter the address in the browser: http://www.sina.com.cn:8080/mail/1.html can access their Web applications, and the port number can not write, but need to set 80 in the Server.xml file port;

Two

Of course we can just type in http://www.sina.com.cn to access our web apps: We need to specify the default directory, That is, put the value of path in the label we just added in the server.xml file to null, and then create a new folder in the Mail folder named Web-inf, which creates a Web.xml file, which is written in the following file:


<?xml version= "1.0" encoding= "iso-8859-1"?> <web-app xmlns=


"Http://java.sun.com/xml/ns/javaee"
  Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemalocation= "http://java.sun.com/xml/ns/ Java EE
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd "
  version=" 3.0 "> 
  
  
   <welcome-file-list >
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

</web-app >
On the 2nd I did not succeed because the port is set to 80, which means that the input http://www.sina.com.cn access is not successful and may be limited by the security issues of the DNS. You can only http://www.sina.com.cn:8080 access to our own Web applications. In addition, through this method can also help to play the game's peers to solve the problem of plug-in upgrade, just to upgrade the designated server designated as their own host on the line.
Okay, that's it. Complete the configuration of the virtual host.
