Web Server Concerns
Apache systems can normally be synchronized between cluster systems. However, some versions of the Apache-based web server may not function properly if they are cloned rather than installed directly.
Additionally, other supported web servers may not allow for synchronization. In these cases, the individual web servers may need to be installed and configured separately on each system.
The following information is necessary to configure the web server on each system regardless of whether synchronization is used:
• The host name referenced by the web server on the Cache Master must be the real host name of the system (master.company.com and not the cluster host name).
• The host name used by the servlet engine connector (in the case of mod_jk configured using the workers.properties file) must be the real host name of the system running the servlet engine. For example on the slaves, the host name would be slave1.company.com or slave2.company.com and on the master, the host name would be master.company.com.
