Using HP Serviceguard for Linux to Provide High Availability for LAMP, December 2005

Conclusion

HP Serviceguard for Linux provides high availability to the LAMP stack in business critical

environments. By following the recommended procedures one can get a highly available

LAMP stack in an environment where both the database and the web server run in a

consolidated environment on a single server and also in an environment where the web

server and the database run on separate servers.

This white paper has given guidelines on two possible configurations. Variations are

possible such as having Apache along with its Server Root and the Document Root on the

shared file system. Typical configurations for Apache and MySQL are described in the

respective toolkit README’s. The choice of local or shared configuration largely depends

on the cluster manageability and shared storage accessibility.
