Linux runs shengxunwei online customer service system: implementation method of supporting SQL server and MySQL at the same time

Some time ago, I published a series of articles , Let's start with .net core Online customer service system development process .
A lot of friends have been hoping to support MySQL database , Considering that some friends are already using it SQL Server, I can't leave you in the process of upgrading SQL Server Support for , The system must support at the same time SQL Server and MySQL.

To simplify the installation and deployment process , I developed a matching configuration tool .

Using automated configuration tools , Can be in “ Database engine ” In this item , Switch SQL Server and MySQL, Instead of deploying two different programs .

In this article, I will introduce ：

• CentOS Installation configuration MySQL database , Create database , Execute the script to create the table structure .
• install Nginx, Reverse proxy to customer service system server , And set the power on self starting
• install .net core , Deploy the customer service system and start it automatically

I detailed the entire process of the commands that need to be executed , Follow this article in 30 Deploy in minutes .

brief introduction
