1. Server System Management

In general, server system management is the top priority in network management. Especially in small-sized networks, the network size of a unit is relatively small, and network devices are relatively simple, basically, it is silly.

The server system here includes two aspects: network server and application server system. Server System Management is the most important part of network management, because it is the core of the entire network, whether it is the network operating system itself, a variety of network servers and application servers.

Specifically, server system management mainly involves installing, configuring, and managing network operating systems, file servers, DNS, WINS, DHCP, and other network servers, and application servers such as Web, FTP, E-mail, RAS, and NAT. The ultimate goal of server system management is to ensure that various protocols and services of the server work properly and that all performance indicators of the server are properly played. In addition, you also need to update the server system version or patch in a timely manner, which is not only related to the performance of the server, but also to the security of the entire network system, because new security vulnerabilities are constantly detected in the operating system, installing patches in time can effectively block and fill these security vulnerabilities.

At present, the emphasis and difficulty in server system management are of course the management of various network operating systems. This includes the management of mainstream Windows, Linux, and UNIX network operating systems of different versions. Each system involves a lot of specific management work, which is very complicated. However, these are necessary for the network administrator. At least, in most small and medium-sized enterprises, network administrators should master the management of mainstream Windows and Linux network operating systems. UNIX and Linux systems are the most widely used among some large enterprises or special industries such as finance, securities, and insurance. Therefore, for professional network administrators, UNIX and Linux System Management, and must be mastered. Of course, the management of other application servers is also very important and must be mastered.
