===== Apache Server Name Indication (SNI) =====
{{tag>Linux Apache}}

This following are Apache configuration examples on how to implement SNI or domain name based virtual hosting.  The following examples also include unique SSL certificates for each domain name.

**The two main requirements are;**
  * **NameVirtualHost** enabled in the main Apache httpd.conf file.
  * Unique **ServerName** for each site domain name each in their own VirtualHost section.
==== Apache General Config ====
<file>
[root@SERVER ~]# cat /etc/httpd/conf/httpd.conf
NameVirtualHost *:80
NameVirtualHost *:443
</file>

==== SITE1.COM Config ====
<file>
[root@SERVER ~]# cat /etc/httpd/conf.d/SITE1.COM.conf
<VirtualHost *:80>
    ServerAdmin hostmaster@SITE1.COM
    DocumentRoot /var/www/SITE1.COM
    ServerName SITE1.COM
    ServerAlias www.SITE1.COM
    ErrorLog logs/SITE1.COM-error_log
    TransferLog logs/SITE1.COM-access_log
    CustomLog logs/SITE1.COM-custom_log common
</VirtualHost>

<VirtualHost *:443>
    ServerAdmin hostmaster@SITE1.COM
    DocumentRoot /var/www/SITE1.COM
    ServerName SITE1.COM
    ServerAlias www.SITE1.COM
    ErrorLog logs/SITE1.COM-ssl_error_log
    TransferLog logs/SITE1.COM-ssl_access_log
    CustomLog logs/SITE1.COM-ssl_custom_log common

SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/WWW.SITE1.COM.crt
SSLCertificateKeyFile /etc/pki/tls/private/WWW.SITE1.COM.key
SSLCertificateChainFile /etc/pki/tls/certs/CA-ROOT.crt
#
# Rest of SSL config
#
</VirtualHost>
</file>

==== DEMO.SITE2.COM Config ====
<file>
[root@SERVER ~]# cat /etc/httpd/conf.d/DEMO.SITE2.COM.conf
<VirtualHost *:80>
    Redirect 301 / https://DEMO.SITE2.COM/
    ServerAdmin hostmaster@DEMO.SITE2.COM
    DocumentRoot /var/www/DEMO.SITE2.COM
    ServerName DEMO.SITE2.COM
