HP Serviceguard Contributed Toolkit Suite Version A.04.02.02 on Linux User Guide (December, 2012)

1. When the Apache server is installed, the default Apache instance might be configured to

automatically startup during system startup via the runlevel (rc) scripts in the /etc/rc.d

directory. In such a case, disable the automatic startup of Apache.

2. Configure the Apache server.

For more information about configuring the Apache server, see Apache Web Server

documentation.

3. Create a separate, distinct server root directory and server configuration file for each Apache

SG/LX package.

This server root directory corresponds to the Apache ServerRoot directive specified in the

configuration file. Each package corresponds to a unique Apache instance with its associated

configuration and server root directory.

4. Configure all Apache instances to listen to package re-locatable IP addresses using Listen

directives.

For example, the configuration file for an Apache instance that combines IP-based and

name-based virtual hosts would include the following directive:

Listen aaa.bbb.c.d:ee

NameVirtualHost aaa.bbb.c.d:ee

ServerName web.site1.url

DocumentRoot /shared/httpd/www-site1

</VirtualHost>

ServerName web.site2.url

DocumentRoot /shared/httpd/www-site2

</VirtualHost>

For more information about configuring virtual hosts, see the Apache Web Server

documentation.

Supported configuration

This section explains the following supported configurations for Apache toolkit packages:

• Local configuration

• Shared configuration

• Multiple instance configuration

Local configuration

In a typical local configuration, files are not shared among the nodes. Identical copies of the

Apache server configuration file and web documents reside in exactly the same locations on each

node. If you update the information in a file on one single node, you must update the files on all

the other nodes with the same changes. The administrator must ensure that all the files on all the

nodes are identical and always up-to-date. This local configuration setup is more useful in scenarios

where the information on the Web page is static and does not change very often.

Shared configuration

In a typical shared configuration, the document root directories reside on a shared file system. You

can place the server root directory in this shared file system. However, this is optional. By placing

the files and directories on a shared file system, the information automatically becomes accessible

to all the nodes in the cluster. You need not maintain copies of all the files and directories on every
