多个应用共享一个 MySQL 数据库

Question

I'm building project that has many apps in it (microservice architecture) and all of them are sharing one mysql database. Is it possible to grant access to several tables in database? For example, I want that my app1 only has access to one table in database not all of them. Thank you!

Answer 1

Yes, you can grant various privileges to various users in MySQL, and in most database servers such as Postgres, H2, MS SQL Server, and so on.

Create a user for each application. Grant permissions to certain tables for each of those users.

GRANT type_of_permission 
ON database_name.table_name 
TO ‘username’@'localhost’ 
;

Commonly used permissions include:

• ALL PRIVILEGES (full access to database or entire database server)
• CREATE
• DROP
• DELETE
• INSERT
• SELECT
• UPDATE
• GRANT OPTION (granting/revoking privileges to other users)
