windows10 under Mysql5.7 Installation Guide

background

On the occasion of the 70th anniversary of National Day, in order to carry forward the majority of domestic software development industry, I decided to use MySQL5.7.
Pooh! The reality is that the company's project using a Mysql5.7, but the official server in a foreign country, but also a test server in a foreign country, the key problem is that my development is domestic, so I started a project is likely to error: Database connection error / MongoDB connection error / Redis connection error / MQ connection error, then I have to build a set of their own. In fact, I have a set of environmental else, but my Mysql is 8.0, so the production and development with the environment is not the same. So I just installed Mysql5.7 2 on my little HP shadow elves. (Yes, I have a Mysql5.6 installation, Mysql5.7 and Mysql8.0 on this notebook, ports are 3306,3307,3308)
