System Performance Tuning for CentOS servers Linux is an open-source operating system that supports various hardware platforms. Linux servers are world-renowned. The main difference between Linux and Windows is that, by default, a Linux server does not provide a GUI (graphical user interface) but a command line interface. The main purpose of the GUI is to efficiently process non-interactive processes. The r

More and more IT organizations tend to use server virtualization to transform the data center into a "service-centric" Resource Sharing pool, A smart network is used to dynamically merge, layer, configure, and access these resources. Standard Server resource virtualization can dynamically increase the performance level and reduce the total cost of ownership (TCO). At the same time, through virtualization, IT organizations can quickly deploy and expand resources as needed, to meet business and

Overview of how Web servers work Many times we want to knowhow a Web container or Web server (such as Tomcat or JBoss) works. how do they handle HTTP requests from all over the world? What did they do behind the scenes? What role does the Java Servlet API (such as Servletcontext,servletrequest,servletresponse and Session classes) play in? These are important questions or concepts that a Web application deve

Interface, referred to as "WSGI") appears. The advent of WSGI allows developers to separate the network framework from the choice of Web servers, no longer restricting each other. Now you can really mix and match different Web servers with network development frameworks and choose the combination that meets your needs. For example, you can use a gunicorn or Nginx/uwsgi or waitress server to run a Django,

Virus classification in LinuxString 2 Linux has always been regarded as an enemy of Windows systems, because it is not only secure, stable, and cost-effective, but also seldom finds virus spreading. However, as more servers, workstat

systems (including DOS and Windows) were rarely intruded by various viruses at the beginning of their production. After 27 years of development and improvement, Unix has become very solid, and Linux basically inherits its advantages. In Linux, if it is not a super user, it is difficult for programs that maliciously infect system files to succeed. With the wide application of Linux on servers, a variety of

However, if you think MAC tools are too complicated, you only need to change the permissions of some executable files to 700, and only allow root users to use them. ◆ Firewall. You must restrict inbound and outbound traffic to prevent malicious connections to and from the server. For various types of servers, protecting inbound traffic is a

the shortage of physical memory, it occupies too much virtual memory, and the performance of applications will be significantly reduced, to ensure high performance of applications, physical memory must be large enough. However, excessive physical memory may cause a waste of memory resources. For example, in a 32-bit processor Linux operating system, physical memory exceeding 8 GB will be wasted. Therefore, to use larger memory, we recommend that you install a 64-bit operating system and enable

. 　　Virtualization as the only way to integrate When it comes to server consolidation, the idea that many CIOs view virtualization as the only way is too limited. Virtualization is powerful and flexible, but some of the consolidation approaches like application software and operating system (storage) stacks are also attractive because they do not increase administrative costs for the enterprise, nor do they require complex virtualization processes.

Microsoft's IIS and SQL Servers are often a major part of the windows-based Distributed application environment. This means that they are also the most frequently targeted targets. In this article, we will provide some specific recommendations to improve the security of these products. Recommendations for improving IIS security There is a programming interface called ISAPI in IIS that is related to files th
