Can't query data base after deploy app

Question

Hi everyone, I’m having an issue after deploy app. I’m using Tomcat8 and MySQL, everithing is running ok. I reach the app deployed from web browser and if I test database conection from console is running too: root@pgi:~# mysqladmin -u root -p status Enter password: Uptime: 51967 Threads: 1 Questions: 45 Slow queries: 0 Opens: 115 Flush tables: 1 Open tables: 34 Queries per second avg: 0.000

The problem is when I try to query the database from app, I can’t login. I can’t reach the db from app-.

this is the spring conf conection file:

		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/xxxxx_db" />
		<property name="username" value="test" />
		<property name="password" value="xxxxxxxxxxx" />

is there some extra config in this scenario? Thanks!

When creating a user from the CLI, you should use something such as:

create database dbname;

grant all on dbname.* to 'dbuser'@'localhost' identified by 'dbpass';

That should allow a successful connection to the database dbname using the user dbuser and the password dbpass (of course you should sub in your own details).

From looking at their documentation, you shouldn’t need the port 3306 attached since you’re using localhost. If you were connecting remotely, then you would specify a port. When connecting locally, it shouldn’t be needed.

So we’d change this:

<property name="url" value="jdbc:mysql://localhost:3306/xxxxx_db" />

To:

<property name="url" value="jdbc:mysql://localhost/xxxxx_db" />
