带有RDS和Elastic Beanstalk的phpMyAdmin

Question

I have an app loaded with Amazon Elastic Beanstalk and DB at Amazon RDS. My Application is able to contact Database which is functioning well and I can connect to mySQL from AWS EC2 CLI.

Problem: I can't get phpMyAdmin to connect to my Amazon RDS instance. (Error #2002 Cannot log in to the MySQL server)

Answer 1

In config.inc.php try using $cfg['Servers'][$i]['host'] = 'localhost'; or $cfg['Servers'][$i]['host'] = '127.0.0.1';

What is probably happening is that your MySQL server is not accepting connections from outside IP addresses; when you use the full hostname in the host directive it appears to come from an external connection (even though it's on the same machine the networking looks up the host differently). Either of those values will force it to connect without going to the external address (though they use different means which is why we'll try both).

When trying with 'localhost' you may also need to change the connect_type to 'socket'.

Answer 2

This was taken from a comment in another similar question:

Try changing the host to your RDS endpoint:

$cfg['Servers'][$i]['host'] = 'localhost' to $cfg['Servers'][$i]['host'] = 'xxx.xxxxxxxxxxxx.us-east-1.rds.amazonaws.com'
