Before web servers had virtual hosts, you would have had to had a physical server for each website that you wanted to produce.
Virtual hosts allow you to run multiple sites from a single physical server.
The HTTPD example index.html page is located at /usr/share/httpd/noindex/index.html. If you want to use the HTTPD example index.html page as a template for your site, copy the index.html to /var/www/html.
Be certain to use the cp (copy) command and not the mv (move) command. The mv command can create files with an improper SELinux context.
[root@server1 ~]# cp /usr/share/httpd/noindex/index.html /var/www/html
By default, the /etc/httpd/conf/httpd.conf file has the following. This markup is what tells HTTPD to serve content from the /var/www/html directory, and to serve index.html as the default document, when navigating to www.emample.com. As an example, if your index.html file is in the /var/www/html directory, when requesting www.example.com, HTTPD knows to get the index.html file from the /var/www/html directory. This is the ideal configuration if HTTPD will only be serving one website.
ServerName www.example.com DocumentRoot "/var/www/html" <IfModule dir_module> DirectoryIndex index.html </IfModule>
Create a unique directory for each site.
~]# mkdir /var/www/site1 ~]# mkdir /var/www/site2
Add an index.html file for each site.
~]# touch /var/www/site1/index.html ~]# touch /var/www/site2/index.html
Add unqiue text to each index.html file.
~]# echo "Welcome to site1" > /var/www/site1/index.html ~]# echo "Welcome to site2" >/var/www/site2/index.html
In the /etc/httpd/conf/httpd.conf file, comment out or remove the ServerName and DocumentRoot lines. Also, add IncludeOptional sites-enabled/*.conf to the very end of the file.
# ServerName www.example.com # DocumentRoot "/var/www/html" IncludeOptional sites-enabled/*.conf
Create the sites-enabled directory.
[root@server1 ~]# mkdir /etc/httpd/sites-enabled
Create a file named vhosts.conf in the sites-enabled directory.
[root@server1 ~]# touch /etc/httpd/sites-enabled/vhosts.conf
Add the following to /etc/httpd/sites-enabled/vhosts.conf file.
<VirtualHost *:80> ServerName www.site1.com DocumentRoot "/var/www/site1" </VirtualHost> <VirtualHost *:80> ServerName www.site2.com DocumentRoot "/var/www/site2" </VirtualHost>
Restart HTTPD, and ensure HTTPD is active and running.
[root@server1 ~]# systemctl start httpd [root@server1 ~]# systemctl status httpd
Configure your DNS server to resolve www.site1.com and www.site2.com to the IP address of your HTTPD server.
You should now be able to navigate to www.site1.com and www.site2.com, and get unique .html files.
