35
To test, try to run the clog package on each node in the cluster. From the “Summary” page, select the
clog package, then from the “Administration” menu, select “Run Package” to run the package on the
first node, then “Move Package” to run the package on the second node.
Configuring a sample package
In this section, you will configure a Serviceguard for Linux package, called ws, for an Apache web
server using scripts from the Apache Toolkit. The content for the web server will reside on the shared
volume group, vgws, and will be accessed from a browser at a relocatable IP address. This way the
user browsing the content will not need to know which node is hosting the web server. He or she can
access the web browser from using a single URL, regardless of which node is hosting the web server.
