The system will now install all the components that we chose earlier.

After we see this we need to reset the password for ISPConfig and RoundCube.

Well done! ISPConfig installed and configured correctly :D

Now you can access to your ISPConfig installation at: or

The default ISPConfig username is admin and the password is also admin

Warning: This is a security risk. Please change the default password after your first login.

You will need to edit the username and password in /var/lib/roundcube/plugins/ispconfig3_account/config/ of the roundcube user, as the one you set in ISPconfig

To change ISPConfig password: Under System, CP Users, click admin, then change the password.

To change roundcube password, edit the file /var/lib/roundcube/plugins/ispconfig3_account/config/

Create a new Web Site

First, we need to create a new client called Client1. In ISPConfig, click Client. Click Add new Client. Fill in the information and click Save.

Click Sites and choose Add New Site. For this new site, choose Client1 as the client. Under domain, type This is the URL for our web site.

Choose to enable SSL and specify Fast-CGI under PHP. Click Save when done.

Make sure you have your DNS pointing to the IP address of the server. Launch your favourite browser and go to You will see your site here.

Securing the web site

Right now, the site is not secure. Click on the site and choose SSL tab. From here, fill in the information and choose to create a new SSL certificate. Click Save.

Next, we want to redirect all HTTP traffic to HTTPS. To do that, edit:

vi /var/www/

Enter contents as follows:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Now exit, save the file and restart Apache server:

service apache2 restart

From now on, when you access the site using HTTP, the site automatically redirects you to HTTPS which is more secure. Note that the site utilizes a self signed certificate which is treated as not secure by browsers. In the future, we will have to add a commercial certificate to this site to make it perfect.
