Overview of Web Servic

The Web server generally refers to the website server, which refers to the program that resides on a certain type of computer on the inetrnet and can provide documents to Web clients such as browsers. You can place website files for the world to browse, and you can place data files for the world to download. At present, the three most mainstream Web servers are Apache, Nginx and IIS.

Overview of IIS

Is a basic Internet service based on running Microsoft Windows provided by Microsoft. It includes Web server, FTP server, NNTP server and SMTP server, which are used for web browsing, file transfer, news service and mail sending, respectively. It makes it easy to publish information on the network (including the Internet and local area network).

Install IIS

1. Open the Server Manager in 2008 R2 and add roles

two。 Add roles required for web server (IIS)

3. Select a role service, which is fine by default

4. Determine the installation

Configure the Web site

Open the Internet Information Services Manager in the management tool and expand the window on the left, which can be configured here.

1. Configure the IP address and TCP port of the site

two。 Configure physical paths and connection restrictions for the site

3. Set the default document for the site, authentication

Advantages of configuring virtual directories

* distribute data to different disks or computers to facilitate separate development and maintenance

* the logical structure of the web site will not be affected when the data is moved to another physical location

The role of virtual host

In order to improve the utilization of resources, you can run multiple websites on one server, which are called virtual hosts, and generally have the following three implementations:

* use different IP addresses

* use the same IP address, different port number

* use the same IP address, same port number, different hostname

Because it is a waste of resources to apply for an IP address for each site, it is not realistic, and it is not convenient for users to access it with a different port number, so using a different host header is the most common method.
