I'm running mysql on ec2 instance. I can connect to this db by doing an SSH to that instance and then connecting to mysql server on command line. But when I try connecting to it via mysql JDBC I get connection timeout error. I have an RDS instance also that has mysql to which I can connect through mysql JDBC. What might be the issue?
转到ec2实例的安全设置,请打开端口号3306,您应该可以连接到mysql
