在web应用程序中更新Dockerfile，如下所示：

更新app db中的Dockerfile，如下所示：

然后运行命令：

docker-compose up
docker ps

输出如下，系统启动：

要在

app db

容器中连接MySQL服务器，项目中的JDBC连接url应如下所示：

"jdbc:mysql://DOCKER_MACHINE_IP:3306/DB_NAME".

在app db容器端，从命令行访问MySQL，为具有DOCKER\u MACHINE\u IP的用户创建并授予权限：

> CREATE USER 'root'@'DOCKER_MACHINE_IP' IDENTIFIED BY 'root_password'; 
> GRANT ALL ON *.* to root@'DOCKER_MACHINE_IP' IDENTIFIED BY 'root_password';
> FLUSH PRIVILEGES;

您可以添加一些日志或输出吗？并确保端口3306未被任何应用程序使用。您的意思是

docker compose logs

？是的，如果有任何应用程序日志，也可以

运行。sh

做什么？你能提供脚本的内容吗？容器已经安装好了，但我想它没有连接到MySQL。有人能帮我吗？似乎目标文件夹下的项目在连接数据库之前无法启动。能否添加catalina和localhost完整日志？另外，请检查mysql是否有您想要创建的数据库。是的，没有我想要创建的数据库，并且请发现部署过程看起来很正常。严重日志与和有关。我编辑了从应用程序访问MySQL的答案。
