How To Install the Apache Web Server on Ubuntu 16.04

Create directory for public html:

$ sudo mkdir -p /var/www/(__domain_name__)/public_html

Create virtual host file for domain:

$ sudo vim /etc/apache2/sites-available/(__domain_name__).conf

Host file contains:

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName (__domain_name__)

        ServerAdmin admin@(__domain_name__)
        ServerName (__domain_name__)
        ServerAlias www.(__domain_name__)
        DocumentRoot /var/www/(__domain_name__)/public_html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        # LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Enable virtual host file:

$ sudo a2ensite (__domain_name__).conf
$ sudo service apache2 restart
