To host websites www.example1.com and www.example2.com on a single node with Apache2 on a single IP, you can use VirtualHost as follows.
/etc/httpd/conf/httpd.conf and add the following lines:
NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/example1.com ServerName www.example1.com # Other directives here </VirtualHost> <VirtualHost *:80> DocumentRoot /var/www/example2.com ServerName www.example2.com # Other directives here </VirtualHost>
Then you can store your websites under the corresponding directory specified with DocumentRoot for each domain.
After restarting Apache2 by
# apachectl restart or
# systemctl restart httpd.service or
# service httpd restart or other distro specific commands, each domain (point to the web server) will be in each own’s directory.
Note that www.example1.com and example1.com are two different domains and you will need to set up two virtual hosts if you want to use both.
