Nginx is a server software that is also a high-performance HTTP and reverse proxy server, as well as a proxy mail server. In other words, we can publish the website on the Nginx, can realize the load balance (enhances the reply efficiency, avoids the server crashes), but also can realize the function as the mail server to send and receive the mail. And the most common is to use Nginx to achieve load
In general, load balancing is the client's request to the backend of the various real servers to achieve load balancing purposes. There is another way is to use two servers, one as the primary server (master), the other as a hot Standby, the request is all to the primary server, when the primary server, immediately swi

1. Load Sharing-solutions for large service nodesA large amount of access traffic and users are the goal of information service providers. However, a large amount of access will impose a heavy burden on servers. As the number of users of excellent Internet application services increases, the server becomes overloaded. If a large number of user service requests cannot be processed in a timely manner, service interruption may occur. In the past, when so
