 ## 如何使用 mysql 数据库进行集成测试
 首先在docker容器里部署一个 mysql 数据库
 ```
-docker run -e "MYSQL_DATABASE=test" -e "MYSQL_ALLOW_EMPTY_PASSWORD=yes" -p 3306:3306 --rm --name mysql mysql:5.7 #(just ctrl-c to stop db and clean the container) 
+docker run -e "MYSQL_DATABASE=test" -e "MYSQL_ALLOW_EMPTY_PASSWORD=yes" -p 3306:3306 --rm --name mysql mysql:8 #(just ctrl-c to stop db and clean the container) 
 ```
 之后便可以基于这个数据库进行集成测试
