Servers constitute the most basic elements in the network infrastructure and are also the most critical part of network security. Although Unix servers are well known for their security and reliability, they do not mean they are impeccable. In addition, the security of UNIX servers affects or determines the security of the basic network structure.

1. Cluster Technology
Cluster technology is a new high-performance computing technology in recent years. It is a single computer system composed of a group of independent computers through high-speed communication networks and managed in a single system mode. Its starting point is to provide high reliability, scalability, and disaster resistance.
A server cluster contains multiple servers with shared data storage space, and each Server communica
Traditionally, servers can be divided into many types based on different criteria. For example, different processors and architecture can be divided into x86 servers, GPU servers, CPU-level computers, and large hosts. Based on different performance levels, it can be divided into entry-level servers, working group-level

Performance Analysis and Optimization of CentOS servers
As a Linux system administrator, the most important task is to optimize system configuration so that applications can run in the optimal state on the system. However, hardware, software, and network environments are complex and changeable, as a result, the optimization of the system becomes abnormal and complex. How to locate the performance problem is a major problem in performance optimization.

For dedicated MSSQL database servers, open only 1433 and 5631 ports, as described above, to set up TCP/IP filtering and policy. For MSSQL, first you need to set a strong password for the SA, use mixed authentication, strengthen the logging of the database log, and audit the "success and failure" of the database login events. Remove unwan
