Installation guide

2. Use the mkfs command to create an ext3 file system on the partition you created in the

previous step. Specify the drive letter and the partition number. For example:

# mkfs -t ext3 /dev/sde3

3. Mount the file system that contains the document root directory. For example:

# mount /dev/sde3 /var/www/html

Do not add this mount information to the /etc/fstab file because only the cluster software

can mount and unmount file systems used in a service.

4. Copy all the required files to the document root directory.

5. If you have CGI files or other files that must be in different directories or in separate partitions,

repeat these steps, as needed.

A.3. Inst alling and Configuring t he Apache HTT P Server

The Apache HTTP Server must be installed and configured on all nodes in the assigned failover

domain, if used, or in the cluster. The basic server configuration must be the same on all nodes on

which it runs for the service to fail over correctly. The following example shows a basic Apache HTTP

Server installation that includes no third-party modules or performance tuning.

On all node in the cluster (or nodes in the failover domain, if used), install the httpd RPM package.

For example:

rpm -Uvh httpd-<version>.<arch>.rpm

To configure the Apache HTTP Server as a cluster service, perform the following tasks:

1. Edit the /etc/httpd/conf/httpd.conf configuration file and customize the file according

to your configuration. For example:

Specify the directory that contains the HTML files. Also specify this mount point when

adding the service to the cluster configuration. It is only required to change this field if the

mount point for the web site's content differs from the default setting of /var/www/html/.

For example:

DocumentRoot "/mnt/httpdservice/html"

Specify a unique IP address to which the service will listen for requests. For example:

Listen 192.168.1.100:80

This IP address then must be configured as a cluster resource for the service using the

Clu st er Co n f ig u rat io n T o o l.

If the script directory resides in a non-standard location, specify the directory that

contains the CGI programs. For example:

ScriptAlias /cgi-bin/ "/mnt/httpdservice/cgi-bin/"

Specify the path that was used in the previous step, and set the access permissions to

default to that directory. For example:

Red Hat Ent erprise Linux 5 Clust er Administ rat ion
