MySQL performance tuning and Architecture Design-Chapter 1 Performance Design-MySQL Replication and replication Optimization Chapter 1 scalability design-MySQL Replication Preface: MySQL Replication is a unique feature of MySQL. It can completely copy data from one MySQL Server Instance to another MySQL Server Instance. Although the replication process is not implemented in real time but asynchronously, the

: This article mainly introduces the Nginx + IIS + Web front-end (SpringMVC)-server load balancer (1). If you are interested in PHP tutorials, refer to it. Introduction When developing a large Web project, if our web is published on the IIS of a server, when a large number of requests are sent to the IIS service, the computer will crash easily. So we thought, why don't we put our services on multiple computers? In this way, a request is sent to

SSH represents a "Secure Shell", so you may think that the most common method is to use it as a remote shell. Maybe this is the most common application, but it is not the only interesting method to use SSH. 1. Connect and execute remote commands and use the authorization key 1. Create a connectio

In other words, source distribution cannot be closed. I heard that MariaDB uses the same communication protocol, so its client library can be compatible with MySQL. It is LGPL, but it does not have a. Net version. Oh, no such bullying. Net. Therefore, I came up with the idea of writing connector first). So I want to study the
