Nowadays, many small and medium-sized enterprises are joining the ranks of deploying enterprise networks to improve their core competitiveness and quickly transfer internal and external information. To achieve centralized network management and reliable use of data information, servers have become an indispensable device. Many users still have vague definitions of servers. In fact, from my own point of view

Source: http://blog.csdn.net/AppleBBS/ ReprintedA few days ago, I suddenly wanted to find a Web server with better performance than Apache. I remember that I was in a large BBS (which has been forcibly disabled by relevant departments) we can see that they are running a 64-bit open-source WebServer on the AMD64 server, which is three times faster than Apache. So I went to Google to find it. Unfortunately, I cannot remember the name of the WebServer at all.Unexpectedly, I saw such an article, whi

With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load

adopts a completely new configuration system that can fully delegate site management, and finally make xcopy deployment of Web applications a reality. The new management API and diagnostic functions make server deployment, management, and troubleshooting easier and more convenient than before. But before the next Windows Server version (codenamed "Longhorn") is about to be released, why should we consider the IIS server application? It is important to consider using it Because Windows Vista wil

Most people run a single MySQL server on a specified machine, but in some cases, running multiple servers is advantageous: you can test the new version of server when the finished server is running. In this case, different servers will run. The operating system usually limits the total process on the number of opened file descriptors. If the system Most people run a single MySQL server on a specified machin

Prerequisites for using IPMITo achieve IPMI management of the server, you must meet the following aspects: hardware, OS, management tools, etc.2.1 The server hardware itself provides support for IPMICurrently, most vendors such as HP, Dell, and NEC support IPMI 1.5, but not all servers are supported, so you should first determine whether the server sup

It is necessary to write concurrent service-side programs while doing network service. The stability of the front-end client application is partly dependent on the client itself, and more depends on whether the server is fast enough and stable enough.

I. Introduction (Baidu Encyclopedia)Samba is a free software that implements the SMB protocol on Linux and UNIX systems, consisting of servers and client programs. SMB (Server Messages block, information service blocks) is a kind of communication protocol for sharing files and printers on LAN, which provides shared services of files and printers among different computers in LAN. The SMB protocol is a client/server protocol that allows clients to acces

Remote backup large capacity often there is the case that the file from remote backup is very large, it takes a long time, you want to exit SSH after the program can still continue to download in the background, can be established through the establishment of inter-server security information relationship and nohup way to solve.There are two servers: a server IP 192.168.3.100, b server IP 121.41.111.46.I.

Currently Azure offers two types of storage for virtual machines, one is standard storage, HDD-based, and one is high-performance storage premium Storage ( PS, hereinafter abbreviated), SSD-based. Provide good support for high performance, low latency, I/O intensive applications such as database MySQL, MONGODB,SAP, etc.This article focuses on best practices for building database servers using premium storage on CentOS, including how to build a 50,000

Design patterns of several concurrent servers under Linux1> single-threaded or single-processThe equivalent of a short link, when the accept, the start of data reception and data transmission, do not accept new connections, that is, a server, a clientThere is no concurrency.2> Loop server and concurrent server1. Loop server: A server can only receive one client at a time, and the next client connection can be made after the current client ends access.
