I have successfully created an AWS RDS SQL Server 2016 instance. I specified a master user name and password. I was able to log into that instance via SSMS using the master user name and password. I then created a database. However, it seems the master user doesn't have any permissions to do anything in that database, such as creating any schema objects. What do I have to do to have essentially db_owner permissions in the database I just created?
Going to sound funny, but try resetting the master user password. Don't know why it works, but it worked for me with a similar problem.

When I create a new database instance in Google CloudSQL, it creates a default user called postgres. I created another user and when I tried to remove the default postgres user I received a message: Can not remove a System user.
Some months ago I could remove the default user without problems. Did google change anything in CloudSQL? How can I remove the default user?
The postgres user is part of the cloudsqlsuperuser role. Because Cloud SQL for PostgreSQL is a managed service, it restricts access to certain system procedures and tables that require advanced privileges. In Cloud SQL, customers cannot create or have access to users with superuser attributes, including the postgres user. This is documented on the PostgreSQL users documentation page.
I have created a read replica for my Production RDS instance,
However I don't know where can I see the log-in credentials of the replica.
When I go to the secrets manages screen and try to create a new secret the replica instance is not present.
And I dont know the password (It usually displays the password after creating a DB in the console).
how would I get the following Info?
username,
password,
dbname
The credentials are the same as the master node.
It is advised to configure credentials on the master node so that they will be replicate to each read only node.
I am using AWS MySQL RDS for my application. Last few days every day my RDS password is reset. Every day, I need to reset master password for my RDS. Is there any solution?
Amazon RDS will not automatically reset your password. Either somebody is changing it, or you have an automated process that is changing it.
If it is the Master password that is changing, you should be able to find a ModifyDbInstance call in your AWS CloudTrail log. It will show the credentials that were used to issue the modify command.
In my case that was a Secrets Manager who automatically rotated RDS instance master password.
Completely forgot about that and panicked a bit when notification about password reset that I didn't issue showed up.
I set up IAM authentication on an RDS instance, and I'm able to use IAM to get database passwords that work for 15-minutes. This is fine to access the database for backups, but this database backs an web application so currently after 15 minutes the password used by the app to connect to the DB becomes invalid and the app crashes as it can no longer access the DB.
However, in the RDS IAM docs there's this line:
For applications running on Amazon EC2, you can use EC2 instance profile credentials to access the database, so you don't need to use database passwords on your EC2 instance.
This implies that on EC2 there's no need to use the IAM temporary DB password, which would mean that my app should be able to connect to the DB as long as it's running on EC2 and I set up the role permissions (which I think I did correctly). However, I can't get my app running on EC2 to be able to connect to the RDS DB except by using the 15-minute temporary password. If I try connecting with a normal MySQL connection with no password I get permission denied. Is there something special that needs to be done to connect to RDS using the EC2 instance profile, or is it not possible without using 15-minute temporary passwords?
According to the documentation you linked (http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.html), you need to perform the following steps (See under "Authenticating to a DB Instance or DB Cluster Using IAM Database Authentication"):
Use the AWS SDK for Java or AWS CLI to get an authentication token you can use to identify the IAM user or role. To learn how to get an authentication token, see Getting an Authentication Token.
Connect to the database using an SSL connection, specifying the IAM user or role as the database user account and the authentication token as the password. For more information, see Connecting to a DB Instance or DB Cluster Using IAM Database Authentication.
That means for every connection you intend to open, you need to get a valid Token using the AWS SDK. This is where using the correct instance profile with the RDS permission is needed. See also the code examples further down the AWS documentation page.
I think however this requires quite a bit of effort on your side, to always get a valid token before opening a connection. It makes using an off-the-shelf connection pool difficult. Probably once open, the connection will remain open even after the token expires, but you still need to handle the case where more connections need to be opened at a later time.
I would stick with a normal user/password access for the application, using IAM for this case seems to be too much effort.
For applications running on Amazon EC2, you can use EC2 instance profile credentials to access the database, so you don't need to use database passwords on your EC2 instance.
You're misinterpreting what this means. It means you don't have to use static passwords or store them on the instance.
The idea is that you generate a new authentication token each time you establish a connection to the database. The token is generated on your instance, using the instance role credentials. It can only be used to authenticate for 15 minutes, but once connected, you don't lose your database connection after 15 minutes. You remain connected.
If your application doesn't reuse database connections, then you likely have a design flaw there.
I need to create a new MySQL user with limited permission on an existing Amazon RDS instance. After encountering a couple error messages I was sort of able to do this using the official MySQL Administrator tool and the user now appears in the list. However, I'm unable to assign any schema privileges as all the users are greyed out. I'm logged in as the "master user" created when the instance was launched. Not sure where to go from here. I do have the RDS command line tools installed but wasn't able to track down anything there either. Ideas
Your best bet is probably to connect to the database with a mysql command line client and call the SQL commands to create a new user and assign him privileges.
For instance, you might run something like this:
mysql -u [your_master_username] -p -h YOURRDSENDPOINT.rds.amazonaws.com
CREATE USER 'jeffrey'#'%' IDENTIFIED BY 'somepassword';
GRANT SELECT ON [your_database].[some_table] TO 'jeffrey'#'%';
On windows you could use the mysql.exe client, wherever that is.

I know this thread is a couple of years old and well I keep finding it so I wanted to get an update out about the AWS RDS and User Permissions.
You cannot use GRANT ALL for any user with an RDS. When you use the GRANT ALL statement you are also attempting to provide Global (as AWS Calls them Super Permissions) and with the way that the AWS RDS System is setup they do not allow assigning of Global Options to users.
You have to break out the Permissions to the following:
GRANT SELECT,INSERT,UPDATE,DELETE,DROP on
This will allow your user to be able to connect to the RDS once the security settings are setup to allow access from your EC2 Instances or from the Internet.
Hope this information helps anyone else that is running into the same issues that I was seeing with the AWS RDS Systems.

I created like this:
CREATE USER 'jeffrey'#'localhost' IDENTIFIED BY 'somepassword';
GRANT SELECT ON mydatabase.* TO 'jeffrey'#'localhost';
But then, AWS rejected to login to that user. And I tried to change Admin privileges, but not success. And I change 'localhost' to '%' through mysql workbench. (or you can remove the user and recreate) like :
CREATE USER 'jeffrey'#'%' IDENTIFIED BY 'somepassword';
GRANT SELECT ON mydatabase.* TO 'jeffrey'#'%';
Then only I was able to loggin through this new user.
In addition:
Once you done this change, then your database allowed to connect from any ip. If you need to improve the security and restrict the accessing ip (Ex: if this is a staging database), you can set the bind-address in my.cnf file in your server.
bind-address = your.ip.add.ress

I had the most success using MySQL Workbench and executing raw SQL against RDS:
CREATE USER 'foo'#'localhost' IDENTIFIED BY 'password';
The bigger problem was permissions. Initially I tried:
Grant ALL on *.* to 'foo'#'localhost'
... which results in an Access Denied error.
Error Code: 1045. Access denied for user 'foo'#'%' (using password: YES)
The troublesome permission is "super" which RDS doesn't give me, and in turn I can't grant. As a result, I'm stuck doing permissions by hand:
Grant SELECT on *.* to 'foo'#'localhost';
Grant INSERT on *.* to 'foo'#'localhost';
Grant CREATE on *.* to 'foo'#'localhost';
I have used mySQL workbench and it works fine. just go to management/Users and Privileges, press "Add Account" button bottom left, and configure. You cannot give SUPER privileges, but most of the rest
