To install Sun Cluster HA for Apache, SunPlex Manager uses the version of the Apache Web server that is included with SolarisTM .

For a list of Apache Web server releases supported by Sun Cluster, contact your Sun sales representative.
SunPlex Manager sets up a basic Sun Cluster HA for Apache configuration with the following structure:

Note: Multiple instances of Sun Cluster HA for Apache
can run on the cluster if the following conditions are met:
For a more advanced configuration, after SunPlex Manager completes the installation, edit the httpd.conf file installed in the configuration directory. See the documentation for the Apache Web server for more information.
To customize your Sun Cluster HA for Apache installation, follow the relevant procedures in the Sun Cluster documentation set.
Before you install Sun Cluster HA for Apache:
Note: If you exit SunPlex Manager or click the Back button in your Web browser after you begin the installation, the installation is disconnected. This disconnection can result in an incomplete installation because of insufficient information or an unresolved error message.
To clean up an incomplete installation, remove the application
files and the resources and resource groups that were created.
The following table describes the input you must provide during installation:
Property | Description |
---|---|
Web Server Port | The port on which the web server accepts requests. Typical values are 80 or 8080. |
Installation Directory | The directory where Sun Cluster HA for Apache will be installed. This directory can be either local or global. |
Root Directory for Web Pages | The directory that contains the Web pages that are served by Sun Cluster HA for Apache. This directory is typically a global directory. |
Web CGI Script Directory | The directory that contains the CGI scripts that are served by Sun Cluster HA for Apache. This directory is typically a global directory. |
Local Log Directory | The directory that will hold the Sun Cluster HA for Apache logs of accesses and errors. This directory must be a local directory. |
Network Resource | Specifies the logical host name or shared address that is to be used to access Sun Cluster HA for Apache over the network. If a logical host name is used, one Sun Cluster HA for Apache instance runs as a failover service. If a shared address is used, multiple Sun Cluster HA for Apache instances run as a scalable service. |
Resource Name | Specifies the name of the Sun Cluster HA for Apache resource that is to be created. This name must be unique within the cluster. |
Resource Group Name | If a shared address is used, this property specifies the name of the resource group that is to be created. This resource group will hold the scalable Sun Cluster HA for Apache resource. If you specify a logical host name, the failover Sun Cluster HA for Apache resource is placed in the same resource group as the logical host name. |
Name Service | The option that controls the Sun Cluster HA for Apache BindAddress parameters. This option normally matches the type of name service in use on the cluster. If you choose DNS, the BindAddress is the logical host name or shared address. If you choose NIS, the BindAddress is the numeric IP value that is associated with the logical host name or shared address. |

installs additional Web pages on the cluster to demonstrate load
balancing across the cluster.
