How To install and configure Apache / httpd Name Based Virtual Hosting.

-

I am using Centos 7.x OS Version and Our Requirement is we need to Create.

Multiple Website in Single server. 



Apache Introduction:-


The Apache web server is the most popular web server all over the world. Virtual hosting is a 

method for hosting multiple websites (domains) on a single server. You can host multiple websites 

on a single machine with a single IP using virtual hosting. All domains on that server will be 

sharing a single IP. Virtual hosting is very useful in shared web hosting environments.

where hundreds of websites are hosted on a single dedicated server. 



1. Install Apache / Httpd PKG.


# yum install httpd* -y                      ( For RHEL and Centos )

# apt-get install apache2 -y               ( For Ubuntu )


2. Start Apache / Httpd Service 


# systemctl start httpd                       ( For RHEL and Centos )

# systemctl start apache2                  ( For Ubuntu )


3. Enable The Service


# systemctl enable httpd                   ( For RHEL and Centos )

# systemctl enable apache2              ( For Ubuntu )



4. Configure Host File


# vim /etc/hosts ( add host entry for Websites )


192.168.122.11   web1.example.com

192.168.122.11   web2.example.com

192.168.122.11   web3.example.com



5. Create Folders For Websites. 


# mkdir /var/www/html/web1

# mkdir /var/www/html/web2

# mkdir /var/www/html/web3



6. Create Web Page For Websites. 


# echo "Hi This is my Web1.example.com webSite" > /var/www/html/web1/index.html

# echo "Hi This is my Web2.example.com webSite" > /var/www/html/web2/index.html

# echo "Hi This is my Web3.example.com webSite" > /var/www/html/web3/index.html



7. Go To Apache / Httpd Configuration Directory.


# cd /etc/httpd/conf.d/                            ( For RHEL and Centos ) 

# cd /etc/apache2/sites-available/          ( For Ubuntu )



8. Now Creating The Virtual Host Files


# vim web1.conf


<VirtualHost *:80>

  ServerAdmin root@web1.example.com

  ServerName  web1.example.com

  ServerAlias www.web1.example.com

  DirectoryIndex index.html

  DocumentRoot /var/www/html/web1

  # Custom log file locations

  LogLevel warn

  ErrorLog /var/log/httpd/error-web1.log   ====  ( Change the Log Path According to Ubuntu )

  CustomLog /var/log/httpd/access-web1.log combined === ( Change the Log Path According to Ubuntu )


</VirtualHost>


Save And Quit File


# cp web1.conf web2.conf

# cp web1.conf web3.conf


Change The All Entry Related To Your Next Website Web2 and Web3 Example:-


  ServerAdmin root@web2.example.com

  ServerName  web2.example.com

  ServerAlias www.web2.example.com

  DirectoryIndex index.html

  DocumentRoot /var/www/html/web2

  # Custom log file locations

  LogLevel warn

  ErrorLog /var/log/httpd/error-web2.log   ====  ( Change the Log Path According to Ubuntu )

  CustomLog /var/log/httpd/access-web2.log combined === ( Change the Log Path According to Ubuntu )



9. Restart Apache / Httpd Service

# systemctl restart httpd                     ( For RHEL and Centos )

# systemctl restart apache2                 ( For Ubuntu )


10. Open Your Web Browser And Go To The URLs
