Connect to MySQL on AWS from local machine - mysql

I am trying to set up a dev environment on my local machine that accesses a MySQL DB on AWS, but I keep getting a "Can't connect" message.
mysql_connect('xxx.xxx.xxx.xxx:3306', 'USERNAME', 'PASSWORD');
I also commented out the bind-address in the my.cnf file, and granted permissions to the IP address that is connecting.
Anyone ever successfully get this working?

My experience in Aug-2013 was as follows for an RDS instance created through Elastic Beanstalk.
0) Assuming the RDS instance has already been created
1) Log in to the management console: https://console.aws.amazon.com/console/home
2) Select Services->VPC
3) Select Security Groups (on the left hand side)
4) Select the group whose description says "Security Group for RDS DB..."
5) In the Security Group Selected panel at the bottom of the page, choose "Inbound"
6) Select MySQL as the rule.
7) Type the ip address of my local machine e.g. 145.23.32.15/32
8) Click Add Rule and Apply Rule Changes
After doing this I could connect to the database using mysql from my local machine.
a) From management console select Services->RDS
b) Click on DB Instances (I have only one) and select "Go to Details Page" for the required instance
c) Obtain Host and Port from the endpoint
d) From a terminal session do soemthing like: mysql --host blah.blah.blah.us-west-2.rds.amazonaws.com --port 3306 -u my-user-name -p

If you are using MySql on AWS via an RDS instance you must add the IP address you want to connect from to the "DB Security Groups". To do this go to your AWS Managment Console and select RDS.
1. Select "DB Security Groups" on the left panel
2. Select "default"
3. Select "CIDR/IP" from the select box and enter your workstations public IP address. Example:
23.234.192.123/32 (dont forget the /32 for a single ip)
4. Click "Add"
5. Wait a few minutes for it to go into effect and then connect your MySql client.
This only applies for RDS instances, if you are using MySql installed on an EC2 instance then the instructions are the same as accessing MySql from any remote machine.

I suppose this is firewalled by Amazon, try using a SSH tunnel:
http://blogs.oracle.com/divyen/entry/connecting_mysql_server_on_amazon
Note: Do not open MySQL to the public internet, not even when using IP filtering. SSH tunnels are way more secure. Best part of it: The tunnel could be accessible with localhost:3306 on your machine, no need to change the config : )

I am on a Windows 7 machine, and had to make the following 3 changes to be able to connect to AWS RDB.
VPC Security Group update in AWS Console (similar to what mikemay has above)
From https://console.aws.amazon.com, click on Services (top left) and choose VPC.
Next select Security Groups
Click on the Security Group which has the description "Security Group for RDS DB..."
On the "Inbound" tab, choose "MYSQL" in the Create a New Rule dropdown.
Add your IP address in CIDR format and click on Add Rule.
Click on Apply Rule Changes.
my.cnf update in local MySQL configuration
Change "bind-address = 127.0.0.1" to "bind-address = 0.0.0.0"
Comment out "skip-networking"
Turn OFF Windows Firewall
Go to Control Panel/System and Security/Windows Firewall and turn OFF Windows Firewall.
After these changes, I am able to connect through both
MySQL WorkBench using Database->Connect to Database
Command Prompt with
mysql.exe -h <AWS DB Endpoint> -U <UserName> -P <Port Number, likely 3306> -p

I have been using MySQL Workbench http://www.mysql.com/products/workbench/ with RDS and it works great. Very easy to create and save a new database service instance. Click "New Server Instance" under "Server Administration" and follow the prompts. You will need to enter the information provided in the AWS RDS webpage for that instance (for example, it's endpoint).
NOTE: In order for you to actually connect, you MUST add your IP address in the "DB Security Groups." The link is in the left-hand column, which is titled "Navigation." I use the "CIDR/IP" option (the other is EC2 Security Group). Make sure to include a "/##" after the IP, such as the "/32" they use in the example (you will see it on the page). In a few seconds, the IP address should be authorized.
After that, go back to MySQL Workbench and complete the New Server Instance creation process.
To use the connection, your code might look something like this (that excerpts of my Java code):
String url = "jdbc:mysql://yourdatabasename.foo.us-east-1.rds.amazonaws.com:3306/";
String userName = "your_user_name";
String password = "your_password";
String dbName = "your_db_name";
String driver = "com.mysql.jdbc.Driver";
Connection connection = DriverManager.getConnection(url + dbName, userName, password);

When we create RDS need to configured the firewall to accept mySQL connections from local or other instance, as such the packet is being dropped at the firewall level, to resolve this you need to:
Login into your AWS console Go to RDS
Note down the security group of your mySQL server (in my case awseb-e)
click security groups
click your group in the center menu awseb
click inbound tab
Select mySQL from the list, add the details of your client server and save the rule
NOTE : once you choose my IP ,AWS select your IP , if you need other ip use
https://www.whatismyip.com/my-ip-information/
and add your IP4 IP

Why can't I connect to AWS RDS?

I'm trying to connect to my new AWS RDS I just made.
I followed the "Setting up for RDS" (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_SettingUp.html), then the "Tutorial: Create an Amazon VPC for Use with a DB Instance" (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Tutorials.WebServerDB.CreateVPC.html), then the "Creating a MySQL DB Instance and Connecting to a Database on a MySQL DB Instance" (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_GettingStarted.CreatingConnecting.MySQL.html) but I'm not able to connect to my DB from my computer or my dedicated server on the web.
Following the previous docs, I have this config :
My DB instance
The VPC
The subnetworks
Example of subnetwork's details :
The first security group :
The second security group, calling the first one :
For the first security group, I put both my private IP and the IP of my dedicated server, and their ports.
I even tried to put 0.0.0.0/0 for SSH and TCP, it didn't work either.
For the DB instance, I tried to add the two security group instead of only the db-securitygroup, it didn't work.
I tried to use a different Port for the DB instance, it didn't work.
With MySQL Workbench or with PDO on my dedicated server, I'm unable to connect to the DB : "SQLSTATE[HY000] [2003] Can't connect to MySQL server on [...]"
I think your security groups are incorrect. If the RDS instance is the only thing you currently have running in the VPC, then you should only have one security group, which is assigned to the RDS server, and that security group should have a rule for port 3306 that allows ingress from your personal IP address, and your dedicated server's IP address.
Take a look to this instruction, pay attention to step 3, 4 and 5. It is for ElasticSearch but I think in your case steps are similar

I am not able to connect to mysql server running on Google Compute engine from another instance using internal IP

I located the /etc/mysql/my.cnf file
I changed the bind-address
first to 0.0.0.0 I received a '111 Connection refused'
then I changed it to the instance I am trying to connect to It still says '111 Connection refused'
the firewall rule allows connection on port 3306 using internal ip so I dont know the problem. Thanks
It seems that you have already taken the necessary steps to connect to MySQL server from GCE your instance. Based on the Stackoverflow case here the recommendation to resolve this problem is to comment this line below (add # at the beginning of the line) in your my.cnf file:
skip-networking
Once done you need to restart MySQL service
sudo service mysql restart
On the GCP side, if you have allowed the IP ranges you want to use with the specified port(3306), it should work fine.
You can also use “nmap” command to verify if port 3306 is open on your GCE instance with MySQL installed.
GCP provides CloudSQL which is a managed MySQL instance. You can access CloudSQL from your GCE VM using private address. This feature reached beta recently. This link provides detailed information about using private IP to connect to your Cloud SQL instances.
Before configuring a Cloud SQL instance to use private IP, you need some steps to be taken. This document provides step by step instructions for configuring an instance to use private IP.
You can use 'netstat -tunlp | grep 3306' command to verify that the MYSQL process is running on port 3306.
This error can also occur when mysql user account does not accept connections from any IP addresses. It may still use localhost parameter to connect to the server. I would recommend adding a user with remote access or granting existing user access to remote sources. You can see this: link for the similar issue and follow the steps recommended there to resolve.

Connecting MySQLWorkbench to Amazon Web Services EC2 Instances

I have no idea how to connect mySQL to amazon EC2 Instance. Here is the screenshot of mySQL workbench: mySQL. I try to change the HostName to the Public IP being provided by the instance, however when i press test connection, it keep promoting this error: Error Message. So what should i do as of now? Thanks!!
Since I cannot put a comment, pardon me for putting this to the
Answers Section
Error 10060 is a generic error that means your client cannot reach the server.
Try pinging your server IP, if it responds, it is online.
Are you sure that the port that EC2 uses is also 3306? Configure your EC2 Instance to allow remote connections. Check the EC2 Security features, something might be blocking you.
AFAIK, the root user is only limited to localhost. So it won't work if you use it remotely. Create a new user with the privileges that you only need, then use the '%' wildcard which means any host.
And finally, you may want to try this: Step by Step instructions
In your EC2 instance you will have a Security Group Column.
Click on that will open the security group page
In the bottom of the page you have a tab called Inbound
Click Edit and then Add Rule to allow port 3306.
In source select anywhere option.

Finding Hostname of MySQL installed on AWS

I am not able to figure out hostname of my MySQL database which is installed on AWS T2 micro server.
I can connect via phpmyadmin. And connecting via PHP code as localhost works ok too.
However can't find hostname or ip which is needed to connect it from service hosted on other server (where localhost won't be an option)
Tried running following
SELECT variable_value FROM global_variables WHERE variable_name = 'hostname'
However the output is ip-172-31-23-11. This doesn't work as hostname when I try to connect.
The output from SELECT variable_value FROM global_variables WHERE variable_name = 'hostname' is showing you the non fully qualified private DNS name.
This should be fine to connect to this instance from the same VPC but if you need to connect from outside of the VPC then instead you should use the public DNS. This, as with the private DNS, is shown in the EC2 dashboard under the instance details (and elsewhere).
As an example:
You then also need to consider network controls such as VPC ACLs and Security Groups. Make sure the security group of your instance allows access from the originating IP over 3306 (default MySQL port).
You'll also want to check the bind-address in /etc/my.cnf to either allow connections specifically from certain addresses as well as localhost/127.0.0.1 or simply remove or comment out the line to allow MySQL to listen to all incoming traffic.
If the application you're trying to connect to the DB with lives on another server, you'll need to get either the public DNS, public IP address, or create an entry in DNS (Route53) that points "database.example.com" into your public IP/DNS name. You can then use one of those as the connection string within the app.
depending on settings, you may also have to follow some of the instructions here.
you might need to bind mysql to listen on the hosts network interface in order to get outside connectivity.
I suggest using telnet to figure that out. if you can't connect (via the command: "telnet 54.4.54.4 5432" (where 54.4.54.4 is your public ip/DNS/route53 entered hostname) then you need to check your security group as well and make sure port 5432 is open to connections from where you're trying to telnet from.

Unable to connect from local mysql server to AWS RDS db instance

I'm trying to import my .sql dump from local machine to AWS RDS db instance using the command:
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump --host=localhost
--user=root --password=admin e_learning_system | mysql
--host=mydbinstance.cyz1k1vacvdd.us-east-1.rds.amazonaws.com
--user=root --password=adminadmin e_learning_system
but it is throwing this error:
ERROR 2003 (HY000): Can't connect to MySQL server on
'mydbinstance.cyz1k1vacvdd.us-east-1.rds.amazonaws.com' (10060)
mysqldump: Got errno 22 on write
How do I correct this?
In case there is anyone who is still looking for a solution like I was, I managed to get it done by setting the security group in my RDS instance. Just go to that security group, you will find the click in "Security and Network" section. After you are on that security group page, edit the inbound rule, change the source to 0.0.0.0/0 (meaning accept from all) temporarily, and then import your db dump. That should work. But keep in mind you might want to revert it back this setting on production.
Yes, Amazon Beanstalk application and RDS security groups must be same for connecting application to database instance..
Right click on database instance and add a new security group using by beanstalk application..
error 2003 means no connection to mysql server. Check if you allowed the machine from where you connect to RDS in the RDS security group.
I prefer using MySQL workbench. It's much more easier & user friendly than the command line way.
It provides a simple GUI.
MySQL workbench or SQL Yog.
These are the steps that I did.
1) Install MySQL Workbench.
2) In AWS console, there must be a security group for your RDS instance. Add an inbound rule to that group for allowing connections from your machine. It's simple. Add your IP-address.
3) Open MySQL workbench, Add a new connection.
4) Give the connection a name you prefer.
5) Choose connection method- Standard TCP/IP
6) Enter your RDS endpoint in the field of Hostname (mydbinstance.cyz1k1vacvdd.us-east-1.rds.amazonaws.com).
7) Port:3306
8) Username: master username (the one which which you created during the creation of your RDS instance) (root)
9)Password: master password (admin admin)
10) Click Test Connection to check your connection.
11) If connection is successful, click OK.
12) Open the connection.
13) you will see your database 'e_learning_system' there.
14) Now you can export your mysqldump file to this database. Go to-> Server. Click Data Import.
15) You can check whether the data has been migrated by simply opening a blank SQL file & typing in basic SQL commands like use database, select * from table;
I was getting the same error and I solved it by adding mysql.exe... to the firewall of the machine I was connecting to.
