We will setup the perfect web server on Ubuntu using Ajenti Control Panel, which is web based server control panel that is really useful for managing servers, if you are familiar with Webmin, it is similar but with a much cleaner interface, it is slowly growing and has lot of plugins to help you manage your server.
In this tutorial we will be installing the Ajent Web hosting add-on which will make Ajenti even more powerful allowing us to create multiple domains, manage email accounts and databases, etc.
Note:
If you have any questions or comments feel free to post them at the bottom i will be glad to help with any issues.
Install
Step 1
Connect to your server as the admin user via SSH or open a command prompt.
ssh [email protected]
Step 2
We will become root and we will add the repository key. This is used to validate the Ajenti packages repository you will be adding to your sources.
sudo su
wget http://repo.ajenti.org/debian/key -O- | apt-key add -
now we add the repository sources
echo "deb http://repo.ajenti.org/ng/debian main main ubuntu" >> /etc/apt/sources.list
Step 3 Now we update and upgrade our packages to pull the information for the Ajenti repository and to make sure we always get the latest software packages.
apt-get update && apt-get upgrade
We install Ajenti and restart the service
apt-get install ajenti
service ajenti restart
Step 4 Now we will install Ajenti-V , NGINX, Mail Server, Mysql ETC
apt-get install ajenti-v ajenti-v-nginx ajenti-v-mysql ajenti-v-php-fpm php5-mysql ajenti-v-mail
Choose a good password for your MYSQL server 
Next answer Yes to creating directories for web-based administration  OK  Step 4 Now we will restart All Services
service php5-fpm restart
service nginx restart
service ajenti restart
service mysql restart
And now Login to the Web and change the default password
Ajenti will listen on HTTPS port 8000 by default
Default username : root
Default password : admin
https://server_ip:8000
change the default password under password
That’s It now you have a running web server all that is left to do is to add a domain and you are set.
