Is the virtual host under the Linux operating system what we often call the Linux virtual host? In fact, it is not professionally speaking. It is a virtual environment installed on Windows. It is actually just a file. Let's take a closer look at some things about Linux and virtual hosts. First, let’s take a look at the advantages of Linux virtual hosting.

Advantages of Linux virtual host:

1. Open idea, open source code, independent improvement or customization;

3. Complete network functions, built-in TCP/IP protocol;

4. A true multi-tasking, multi-user operating system;

5 , completely runs in protected mode, making full use of CUP performance;

6. Advanced memory management mechanism, more effective use of physical memory;

7. Stability, security, and efficiency ;

8. Compatible with UNIX systems at the source code level and compliant with IEEEPOSIX standards. 9. Supports dozens of file system formats. 10. Device independence and good portability.

Linux-based virtual host construction:

1 Install webmin.

2 Enter webmin to install the virtual-host module.

3 When BIND 9 is installed on the server, the module path in webmin must also be modified accordingly.

4 According to the help manual, 1) recompile apache2 first and add ./configure –prefix=/usr/local/apache/ –enable-suexec2) configure Apache, mainly including modifying the path of httpd, etc. 3) Add NameVirtualHost ip LoadModule suexec_module modules/mod_suexec.so.

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

6 add new virtual-server, fill in the corresponding domain name, account information, and click OK.

Linux virtual host configuration:

1. Virtual host configuration based on IP address:

Step 1: For the host Set their own IP addresses for different network cards in the httpd.conf configuration file;

Step 2: vim /etc/httpd.conf In the httpd.conf configuration file, set different configuration sections for each virtual host;

Step 3: Create directories and homepage files for different virtual sites;

Step 4: Restart the Apache service. Use elinks or enter different IP addresses in the browser to browse to pages with different content.

2. Name-based virtual host configuration:

Step 1: Modify the virtual host configuration section in the configuration file httpd.conf;

Steps Two: Create directories and homepage files for different virtual sites;

Step three: Restart the Apache service.
