MYSQL Connection: Access Denied

Question

These are my codes for the database connection:

Class.forName("com.mysql.jdbc.Driver");
con =DriverManager.getConnection("jdbc:mysql://10.44.222.111/try?" 
+ "user=jenny&password=perez");

After running the program, it display this error :

com.mysql.jdbc.exception.jdbc4.MySQLSyntaxErrorException:
Access denied for user 'jenny' @ '%' to database 'try'

I am using MySQL Workbench.

Answer 1

Go to MySQL Workbench, then User Privileges, click your username, then check all Administrative Roles then click apply. This will allow connection for user 'jenny'.

Answer 2

As the error says, user 'jenny' does not have access to connect to database from any host(%). On mysql prompt, run the following command to provide privileges to user 'jenny' to connect from any host.

GRANT ALL PRIVILEGES ON try.* TO 'jenny'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;

You may use specific PRIVILEGES instead of ALL as per your requirement.

Answer 3

This would indicate that your user does not have permission to access that database from any client host ('%').

MySQL uses a four part mechanism for allowing access:

• username
• password
• database
• client host

You need to make sure that the user is authorised in MySql to access the 'try' database and is allowed to connect from any client host ('%') and has the correct username and password.

Also, you should ensure you are connecting to port 3306 (unless MySQL is running on a non-standard port).
