Web Hosting and Site Hosting allow you to host multiple websites under a single hosting account.
Each website is linked to its own domain and document root.

Managing multiple websites requires careful structure and organization.

How Multiple Websites Work #

Each website:

• Has its own domain or subdomain
• Uses a separate document root
• Can have its own files and database

All websites share the same hosting resources.

Using Addon Domains #

Addon domains are the most common way to host multiple websites.

Addon domains:

• Link a new domain to your hosting account
• Assign a separate folder for website files
• Function as independent websites

Each addon domain has its own document root.

Using Subdomains #

Subdomains:

• Create a website under an existing domain
• Example: blog.yourdomain.com
• Use their own document root

Subdomains are useful for sections or separate projects.

Managing Files per Website #

Each website should:

• Use its own document root
• Have its own folder structure
• Avoid sharing files unless required

Mixing files across websites causes errors and security risks.

Managing Databases per Website #

Dynamic websites should:

• Use separate databases
• Use separate database users
• Avoid sharing databases unless explicitly required

This improves security and simplifies troubleshooting.

Email and DNS Considerations #

Each domain:

• Can have its own email accounts
• Uses its own DNS records
• Is managed independently in cPanel

DNS changes affect only the selected domain.

Resource Sharing and Limits #

All websites:

• Share CPU, memory and storage
• Are subject to package limits
• Can affect each other under heavy load

Poorly optimized websites impact overall performance.

Common Mistakes #

• Uploading files to the wrong document root
• Using one database for multiple websites
• Forgetting which domain maps to which folder
• Mixing configurations across sites

Clear organization prevents issues.

Best Practices #

To manage multiple websites effectively:

• Name folders clearly
• Document domain-to-folder mapping
• Keep software up to date
• Monitor resource usage

Planning reduces maintenance effort.

Responsibility Notice #

You are responsible for:

• Website organization
• Resource usage
• Domain and file management
