SSL/HTTPS - несколько сайтов на одном IP

This tutorial describes how you can host multiple SSL-encrypted web sites (HTTPS) on one IP address with Apache 2.2 and GnuTLS on a Debian Lenny server.

For more information on why this couldn't be done prior to OpenSSL 0.98g or with GnuTLS please refer to http://en.wikipedia.org/wiki/Server_Name_Indication.

I will mention that Virtual Hosting SSLs on the same IP address has 1 or 2 caveats before beginning and before anyone begins ripping out and handing back IPs to their ISPs.

 1.  Firefox 2.0+ works on all platforms (Mac/Windows/Linux) - it has its own TLS implementation - if you have SSLv2 enabled for VMware tools, Firefox doesn't work either, but by default Firefox comes with v2 disabled by default
 2. Windows XP does not support SNI and still has 40% share in the world so you could alienate a lot of people unless they are using Firefox on XP.
 3. Browsers like Safari/Chrome/IE only work on Vista or greater because they use the O/S TLS implementation
 4. Safari/Chrome only work on 10.5.7 or above on Macs

Let's assume you have written a cool Web 2.0 app behind an SSL which only runs in the latest and greatest browsers because of excessive amounts of Javascript the everything I said above will be fine because your website won't work anyway in the older browsers O/Ses anyways without Firefox.

You can test if your browser is passing SNI by visiting here: https://sni.velox.ch/

Let's begin:

apt-get install libapache2-mod-gnutls

a2dismod ssl

a2enmod gnutls

Edit /etc/apache2/ports.conf and add the following line:

Listen 443

Also comment out the following in /etc/apache2/ports.conf:

<IfModule mod_ssl.c>

  # SSL name based virtual hosts are not yet supported, therefore no
  # NameVirtualHost statement here
 Listen 443


Finally create a file called /etc/apache2/ssl.conf:

NameVirtualHost xx.yy.zz.kk:443 <VirtualHost xx.yy.zz.kk:443> ServerName secure.domain1.com:443 GnuTLSEnable on GnuTLSCertificateFile /etc/apache2/ssl-certs/secure.domain1.com.crt GnuTLSKeyFile /etc/apache2/ssl-certs/secure.domain1.com.key GnuTLSPriorities NORMAL DocumentRoot /web/www1


<VirtualHost xx.yy.zz.kk:443> ServerName secure.domain2.com:443 GnuTLSEnable on GnuTLSCertificateFile /etc/apache2/ssl-certs/secure.domain2.com.crt GnuTLSKeyFile /etc/apache2/ssl-certs/secure.domain2.com.key GnuTLSPriorities NORMAL DocumentRoot /web/www2


Add in an include line in /etc/apache2/apache2.conf:

Include «/etc/apache2/ssl.conf»

Finally restart Apache2 with:

apache2ctl restart

Note on Godaddy SSLs:

With Godaddy you normally have you import a gd_bundle into Apache with the following OpenSSL directive:

SSLCertificateChainFile /etc/apache2/ssl-certs/gd_intermediate_bundle.crt

In order to use this root certificate in GnuTLS simply run:

cat gd_intermediate_bundle.crt » /etc/apache2/ssl-certs/secure.domain1.com.crt
