Although Linux has not made noticeable progress in the world of desktop computing, it is already a small celebrity as a Web server. Thanks to its excellent reliability, we can safely run all the important service programs that are necessary for today's internet age on Linux. As a result, some of the most common uses of Linux include being used as mail servers, Web servers, and DNS servers. Here we'll look a

As shown in the following figure, this task consists of the high-availability server Load balancer component and cache DNS. High-availability server Load balancer component requirements: optimize some key links in the business system architecture, load balancing for TCP layer data traffic, and ensure high service availability.

DNSRelated ConceptsDNS (domain Name System), a distributed database of domain names and IP addresses that are mapped to each other on the Internet, makes it easier for users to access the Internet without remembering the number of IP strings that can be read directly by the machine. The process of obtaining the IP address of the host name through the hostname is called Domain name resolution (or hostname resolution). The DNS protocol runs on top of th

DNS (Domain Name server) is a huge distributed database that provides domain-specific information through a domain name server, which is responsible for translating domain names into IP addresses. It is not possible to put all domain name information from the Internet on the same computer, so the DNS system uses a tree
