Apache 2
Contents
Requirements
Before going through this tutorial, I recommend you to setup:
Installation
Apache 2
This will install web server + PHP + Perl + all required libraries.
Apache2 core
apt install apache2 apache2-utils
apt install ssl-cert
Since Ubuntu 16.04 apache2-mpm-prefork
is not required
Doc
apt install apache2-doc
Perl
apt-get install libapache2-mod-perl2 libapache2-mod-perl2-doc
SNMP
Sometimes you might encounter some SNMP errors on latest Debian based distributions.
In that case you have to install a new package and run it.
apt-get install snmp-mibs-downloader
download-mibs

Firewall
see Firewall INPUT filters#Web server
Restart the firewall
/etc/init.d/firewall restart
Test your installation
Restart the Apache2 server
service apache2 restart
Create a simple PHP script
vim /var/www/html/phpinfo.php
Put the following:
<?php
phpinfo();
?>
Adjust rights
chown www-data:www-data /var/www/html/phpinfo.php
chmod 755 /var/www/html/phpinfo.php
You can now test your installation by going to 'http://localhost/phpinfo.php' or 'http://myServer/phpinfo.php'. You should see the default page.
