Summary


Updating servers can be quite a complex task. It is, however, mandatory in order to maintain a secure and robust environment. This chapter touched on a number of the more common configuration tasks. We explored examples of

  • Navigating the two interfaces available for the YaST tool

  • Adding and removing software modules

  • Adding additional storage resources

  • Maintaining the network interface

SUSE LINUX provides the YaST tool that can be leveraged to make server configuration tasks easier and consistent across an enterprise. The YaST utility is provided in both an X Windows System and ncurses interface, allowing the use of this tool on even the most minimal of configurations. In the following chapters, YaST will be the tool of choice used to maintain the various services available on SUSE.

This chapter also explored the various steps required to add additional storage capacity to a server. In doing so, we covered a number of topics ranging from disk partitions, filesystems, mount points, and permissions. In moving data from old directories to the new mount points, we have, in essence, covered methods for backing up data and preserving directory structures and per missions.

One of the most important concepts introduced in this chapter revolves around the network connectivity of servers. We introduced the concept of a secure environment for servers to prevent compromises as we build them. We touched on the importance of keeping systems offline as we are maintaining them. The concept of a DMZ was introduced as a standard practice for securing environments exposed to potentially hostile networks.
