systems from accessing the same data simultaneously, which may result in data corruption.
Therefore, do not include the file systems in the
/etc/fstab
file.
2. Configuring Shared Storage
To set up the shared file system resource, perform the following tasks as root on one cluster
system:
1. On one cluster node, use the interactive
parted
utility to create a partition to use for the
document root directory. Note that it is possible to create multiple document root directories
on different disk partitions.
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.
3. Installing and Configuring the Apache HTTP 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
Appendix A. Example of Setting Up Apache HTTP Server
