In fact, technically speaking, it's a virtual environment that's installed on Windows, and it's actually just a file. Let's look at some things about Linux and virtual hosting. First, let's look at the advantages of a Linux virtual host.

Advantages of Linux Virtual hosts:

1, open the idea of opening source code, self-improvement or customization;

2, free of the spirit of freedom to use;

3, perfect network function, built-in TCP/IP protocol;

4, the real sense of multi-tasking, multi-user operating system;

5, fully operating in the protection mode, fully utilize the cup performance;

6, advanced memory management mechanism, more efficient use of physical memory;

7, stability, safety, high efficiency;

8, with the UNIX system at the source code level compatibility, conforms to the IEEEPOSIX standard 9, supports dozens of file system formats. 10, equipment independence, good portability.

Linux-based virtual host building:

1 Install the Webmin.

2 Enter Webmin to install the Virtual-host module.

3 Server Install the module path in bind 9,webmin should also be modified accordingly.

4 Follow the Help manual content, 1) first recompile apache2 Plus./configure–prefix=/usr/local/apache/–enable-suexec2) to configure Apache, mainly including paths to modify HTTPD, etc. 3) Plus namevirtualhost IP LoadModule suexec_module modules/mod_suexec.so.

5 Enter Http://ip:10000/virtual-host, follow the prompts, remove some unused modules and then run the module successfully.

6 Add new Virtual-server, fill in the corresponding domain name, account information, click OK.

Linux Virtual Host configuration:

1. IP address-based virtual host configuration:

Step one: Set the respective IP address for different network cards in the host;

Step two: Vim/etc/httpd.conf in the httpd.conf configuration file, set up a different configuration section for each virtual host;

Step three: Create directories and home page files for different virtual sites;

Step four: Restart the Apache service. You can browse to a different page by using ELinks or by entering a different IP address in your browser.

2. Name-based virtual host configuration:

Step One: Modify the configuration file httpd.conf in the Virtual Host configuration section;

Step Two: Create directories and home page files for different virtual sites;

Step three: Restart the Apache service.
