This article will help you to setup the hosts, in case you want to run multiple websites on your VPS. This is similar to setting up a shared server that hosts multiple websites, using a single shared IP Address.
This documentation assumes you've already installed the LAMP stack on your VPS. If you haven't done that yet, refer to the LAMP installation guide.
Ensure that you are connected to the server using an SSH client as a root user.
Website management becomes easier through cPanel or Plesk. If you have installed any of these panels, you need not follow this documentation.
The process to host a single website is different from hosting multiple sites.
To Host a Single Website
If you want to host only one domain name in the VPS, then all you need to do is point your domain name to the IP Address of the VPS. This can be done by simply adding an A record for the domain name from the DNS interface of the VPS.
By default, the document root of your server is /var/www/html. You can upload the contents of your site in this directory. The website can also be accessed using the IP Address of the VPS.o Host Multiple Websites
If you want to host multiple domain names in the same VPS, then you would be required to create a virtual host entry in your Apache configuration file. Refer to the steps mentioned below.
Assume you want to host the websites for domain names domain1.com and domain2.com. You'll first have to create directories for each website under /var/www/html. You can create the directories from Plesk Power Panel's - File Manager or via SSH. The steps given below are using the Command Line Interface.
Navigate to the directory /var/www/html.
Create the directories for each website.
The directories will be created as below.
Open the Apache configuration file by using the command:
Scroll down to the end of this file, uncomment the lines and add your domain names as shown below.
The various paramaters in Name based Virtual Hosting are:
NameVirtualHost: Designates an IP address for Name based Virtual Hosting
<VirtualHost>: Contains directives that apply only to a specific hostname or IP Address
ServerAdmin: Email address that the Server includes in error messages sent to the client
DocumentRoot: This directive sets the directory from which httpd will serve files for this host
ServerName: Used to uniquely identify the Virtual Host; FQDN (Fully Qualified Domain Name) format to be used
ServerAlias: This directive is used to set the alternate names for the host
ErrorLog: Location where the Server will log errors for this host
For the configuration changes to take effect, you need to restart the Apache service using the command:
service httpd restart
To check how these sites will resolve or to test their functioning, you can add sample html files.
Create the index.html files for domain1.com and domain2.com.
In order to access the websites prior to setting up their DNS zones, you can edit your local computer's hosts file.
For actual resolution over the Internet, create A records for each domain name pointing to the IP Address of the VPS, in their respective DNS zones.
Uploading Content through FTP
You can upload the content using any FTP client of your choice using the below details:
This is a complete setup with minimal configuration. You can customize or secure your website further as per your needs.
