Check Ubuntu Version:

Use command hostnamectl  to know installed version of Linux

   Static hostname: ip-10-0-1-168
         Icon name: computer-vm

root@ip-10-0-1-168:~#

Step 1: - Check existing installation of Apache

We can check whether our Server already has Apache installed or not using the command below:

root@ip-10-0-1-168:~# dpkg --list apache2
dpkg-query: no packages found matching apache2
root@ip-10-0-1-168:~#

Step 2: - Install Apache 2.4

Use Command below to install Apache 2.4

root@ip-10-0-1-168:~# apt install apache2

Check Installed Apache Version: - 

root@ip-10-0-1-168:~# apache2 -v
Server version: Apache/2.4.18 (Ubuntu)
Server built:   2017-05-05T16:32:00

Check Apache Server Status: -

Using Command below, we can check apache service status

root@ip-10-0-1-168:~# systemctl status apache2.service
● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

root@ip-10-0-1-168:~#

 Ubuntu Firewall: -

Apache Sever using default port 80. To access the website from outside we need to allow Port 80 in Ubuntu Firewall (UFW).

Check Ubuntu Firewall Status using the command below:

root@ip-10-0-1-168:~# ufw status
Status: inactive

In my case Ubuntu Firewall is inactive, If Ubuntu Firewall is Active we need to allow Port 80 using the command below:

root@ip-10-0-1-168:~# ufw allow 80/tcp
Rule added
Rule added (v6)
root@ip-10-0-1-168:~#

 After adding Port 80 reload Ubuntu Firewall using below command 

root@ip-10-0-1-168:~# ufw reload
Firewall reloaded

 Checked open port status using the command below:

root@ip-10-0-1-168:~# ufw status
Status: active

To                         Action      From
--                         ------      ----
80/tcp                     ALLOW       Anywhere
22/tcp                     ALLOW       Anywhere
80/tcp (v6)                ALLOW       Anywhere (v6)
22/tcp (v6)                ALLOW       Anywhere (v6)

Check Apache server using server's IP address:

 After successful installation of Apache let's check server status:

http://localhost

Apache has been installed Successfully:

Step 3: - Create Virtual Host

 We need Vhost to run multiple websites on a single server-  Let's create a virtual host using the command below:

root@ip-10-0-1-168:~# vi /etc/apache2/sites-available/myvhost.conf

Append following code into this file.

<VirtualHost *:80>
    ServerAdmin amar.singh@outlook.in
    ServerName myvhost.org
    DocumentRoot /var/www/html/myvhost/
    ErrorLog /var/www/html/myvhost/logs/error.log
    CustomLog /var/www/html/myvhost/logs/access.log combined
<Directory /var/www/html/myvhost/>
    Options All
    AllowOverride All
    Require all granted
</Directory>
</VirtualHost> 

Save and Exit from File.

Enable created Virtual host:

root@ip-10-0-1-168:~# a2ensite myvhost.conf
Enabling site myvhost.
To activate the new configuration, you need to run:
service apache2 reload

Reload Apache configuring using the command below:

root@ip-10-0-1-168:~# systemctl reload apache2.service

Validate create Virtual host using server name:

http://myvhost.org/

!!!Apache installation and Virtual host creation have done successfully!!!
