Chapter 14. Apache HTTP Server

Note

Any name based virtual hosts you set up will only work with non secure HTTP connections as you

cannot use name based virtual hosts with a secure server. If you need to use virtual hosts with a

secure server, you will need to use IP address based virtual hosts.

If you are using name based virtual hosts, uncomment the

NameVirtualHost

configuration directive

and add the correct IP address for your server after

NameVirtualHost

. Then add more information

about the different domains using the

VirtualHost

tags which surround the

ServerName

for each

virtual host, plus any other configuration directives which are only applicable to that virtual host.

14.5.70.

VirtualHost

VirtualHost

and

/VirtualHost

tags surround any configuration directives which are in 

tended to apply to a virtual host. Most configuration directives can be used within virtual host tags,

and then they only apply to that particular virtual host.

A set of commented out

VirtualHost

tags surround some example configuration directives and

placeholders for the information you would need to fill in to set up a virtual host. Please see Section

14.8, for more information about virtual hosts.

Note

All SSL virtual hosts contexts have been moved into the file /etc/httpd/conf.d/ssl.conf.

14.5.71.

SetEnvIf

The Apache configuration directive

SetEnvIf

can be used to set environment variables based on

headers in the request. In the supplied

httpd.conf

file, it is used to disable HTTP keepalive and to

allow SSL to close the connection without a close notify alert from the client browser. This setting is

necessary for certain browsers that do not reliably shut down the SSL connection.

14.5.72. SSL Configuration Directives

The SSL directives in

/etc/httpd/conf.d/ssl.conf

file can be configured to enable secure Web

communications using SSL and TLS.

For

more

information

on

SSL

directives,

please

point

your

browser

to

http://localhost/manual/mod/mod_ssl.html or the Apache group

mod_ssl

documentation at

http://httpd.apache.org/docs 2.0/mod/mod_ssl.html.

For information about setting up an Apache HTTP Secure Server see the chapter titled Apache HTTP

Secure Server Configuration in the Official Red Hat Linux Customization Guide.

Note

Do not modify your SSL directives unless you are absolutely sure about what you are doing. In most

cases, the SSL directives are configured appropriately as installed.
