 To make our website accessible to public, we need to upload it to a public server  There are 3 common options:  web hosting service  virtual private server  dedicated server

 Web Hosting Service  free (usually very limited and supported by ads)  paid  Virtual Private Server & Dedicated Server  managed  unmanaged

 Other Options  Colocation Server  Cloud Server  Clustered & Grid Hosting  Home Server  etc.

 The scope of web hosting services varies greatly.  The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a web interface.

 We can store several websites in a single hosting account  separate folder  separate FTP account  separate MySQL database  etc.  This allows web hosting reselling

Example from Proaxxss

Example from Godaddy (incomplete)

 Uploading our website to the web hosting is usually done via web interface or FTP.  FTP  FTP Client usually works like file explorer. We can easily uploads several files at once by drag-and- drop  More stable for uploading large files

 Web Interface  can be accessed with browser, no need to install FTP application  sometimes web hosting provides feature for uploading a zip archive and automatically unzips it when the upload completes.

Example : Godaddy’s Control Panel

user only able to store 100Mb of files and can only access /alice/ user only able to store 100Mb of files and can only access /alice/

Example : Godaddy’s Control Panel

Managing domain & DNS Installing web app Creating New Database Accessing phpMyAdmin

 It is possible to control multiple domain names in a single web hosting account (if the hosting plan permits)  primary domain is directed to the document root directory (public_html, var/www, htdoc)  add-on domains is directed to a subfolder inside the document root

 In the Previous Example: primary domain is holicfarm.net

public_html public_html/mi2.me/ holicfarm.net mi2.me mi2me.holicfarm.netholicfarm.net/mi2.me/

public_html/alice/ alice.holicfarm.net holicfarm.net/alice

 Suppose we want a sub-domain to redirect to another website

 VPS is a virtual machine  A single computer can have several VPSs, each one with its own OS and server software  Customer has a superuser-level access  can configure the server  can install any software that runs on that OS  responsible for its security

To the user, a VPS appears like a dedicated server, however, since the hardware is actually shared among other VPSs, performance may be lower and depend on the workload of other instances

Example: Godaddy’s Linux VPS Plan

Example: Godaddy’s Windows VPS Plan

Example: OVH’s VPS Plan (Linux Only)

Example: Godaddy’s Linux DS Plan

Example: Proaxxs’ Linux DS Plan

Example: OVH’s DS Plan

 VPS/DS provider usually provides control panel for basic management:  restarting the machine  reinstalling the OS  upgrading  etc. Example: OVH’s control panel

 There are several ways for managing a VPS/DS  remote desktop (windows)  telnet / ssh  control panel (cpanel, webmin, etc.)

Example: Bitvise SSH Client

 Control Panel is a convenient tools for managing a VPS  if the VPS comes without it, we need to install it first.  cPanel is a popular paid control panel, while webmin is a popular free control panel  not all configurations can be done through control panel

 To hook a domain name to a server is slightly more complicated than to a web hosting: 1. First we need to tell the DNS that our domain is directed to what IP address Example: mi2.me  Second we need to “handle” the incoming request from that domain name to our server by creating a virtual host Example: request from pbw39.mi2.me  var/www/PBW/39/

 Virtual Host’s configuration is stored in /etc/apache2/sites-available Example: Debian8 OS

 The file can be opened using a text editor (usually vi or nano is preinstalled)  command: nano PBW39.mi2.me.conf Example: Debian8 OS

 Domain Names can be bought through a domain name registrar (eg. Godaddy)  To keep the domain name, we need to pay its yearly fee

 Owned domain names are listed in the account control panel

 MX record that points to Google App (was free, but now no longer free)
