INSTALLING THE LAMP STACK ON CENTOS AND THE
DELL POWEREDGE C6220
The LAMP stack – An overview
LAMP describes the components of a possible multi-tier software stack that an
infrastructure may run: the Linux operating system, Apache Web server, MySQL
database, and PHP scripting language. This application stack has been used for years by
service providers to provide powerful and flexible multi-tier environments for
customers. Below, we briefly describe each component and then review the specific
methods for setting up a single-server LAMP stack on the Dell PowerEdge C6220.
Apache

such features as Secure Sockets Layer and Transport Layer Security support, filtering
support, and custom log files. For more information, visit http://www.apache.org/.
