I used a quick start guide to create a mysql database on EC2 that I can access and query using RStudio. However, I'd like to use Tableau Desktop to visualize the data as well. Tableau can connect to MySQL, but Im not sure how to make it work with EC2. I think I need to use port forwarding. I've Googled extensively and found a few examples but I'm completely new to this and don't know where to begin.
I'm using Terminal on Mac OSX. I'm able to login to SSH and to MySQL once in SSH.
Tableau needs a server, port, user, pass, and initial SQL statement. I'm assuming the initial SQL statement is just "use MyDatabase;"
I remember running into this issue awhile ago and found the solution again. I think the main thing to remember is that you have to use the localhost as the address in Tableau after you ssh into EC2 instead of the address of the actual EC2. You also have to setup your ssh to forward the port as you mentioned. Here is how you do that with PuTTY.
In the first screenshot you will see I added 127.0.0.1:3306 as the destination. This is the address of MySQL as setup on your server. I included 9990 as the source port. This is the port that PuTTY will be monitoring for any given calls. Once you have these defined click add and then save your session and connect with your server credentials through PuTTY. Go to Tableau.
In the second screenshot you will see that I used 127.0.0.1 for the server and 9990 for the port that I defined in PuTTY. You then add the credentials in Tableau that correspond to your MySQL user that is setup on EC2.

I followed this article to setup mysql server in my aws vm. At the time of creation of the vm itself I had allowed inbound traffic to port 3306 from all ip addresses.
After creating an admin account, I cannot access the account from outside the vm using sql workbench. I made changes in the property file to change the bind-address to 0.0.0.0 so that remote connections maybe allowed from outside. That also did not help.
What am I missing here? I did everything and still it won't connect. Appreciate any help on the matter.

Based on the comments.
The issue was that mysql was setup to allow access from localhost. To solve the problem, external access needed to be allowed. This can be done by following the guide:
How To Allow Remote Access to MySQL
I just set up a new MySQL database with the MySQL workbench & created a user for it with all necessary privileges. I am using this database for use with my php code. But I can't seem to connect to it on my live server (pages are hosted on windows server 2012). Everything works fine in my local environment with xampp and the new MySQL database is exactly the same as the xampp one. I think I am maybe using the wrong host name or something. As host name I copied the name that is displayed after "Host:" when you click on Server Status in MySQL workbench. The database name, user & password should all be correct. But when my code tries to access the db I get a "The domain page isn’t working. Domain is currently unable to handle this request."
You either have no network connection to the server at all or it is blocked due to firewall or routing misconfiguration.
If you do have network access in general, you might forgot to
FLUSH PRIVILEGES;
or you have not enabled networking over TCP, the default is to listen only to localhost (on unix systems via unix sockets, on microsoft I guess it's simply TCP).
Read about the following configuration parameter which will solve your networking issue:
bind-address
If you have a very old MySQL server version, the parameter is enable-networking but it shouldn't be the case anymore.
I am trying to connect Power Bi (Desktop version) with my online amazon mysql database. It demands for following information once you try to establish connection
Server: server ip
Database: database name
Username: mysql username
Password: mysql password
First time I received a bit lengthy error, which was because of unavailability of mysql-connector-net-6.6.5.msi. So I followed this link to solve the issue
Microsoft Power BI connect to mysql
After installing mysql-connector I am facing another error.
Whats wrong? One of my mates has successfully connected using the same credentials that I am using.
Okay, I just figured this out for myself. I'm able to connect directly to a MySQL database on port 3306. As I understand, it would be more secure to go through an SSH tunnel, but this doesn't work yet with Power BI.
So here are instructions for connecting directly:
First, let's make sure that everything besides the PowerBI connection is working.
1) Download and install the correct version of the MySQL/Net Connector. Right now, version 6.6.5 is the one that works. But from other forums, and from within PowerBI itself, I linked to other versions that did not work. (You will know it isn't working, because you probably won't be able to even open Get Data/MySQL Database/Connect.)
2) See if you can connect remotely to your database through some well established utility like MySQL workbench. If you can't,
- look at ports on the remote server. Here's a cool utility to check ports&IPs: http://www.yougetsignal.com/tools/open-ports/
- Check the permissions of the DB user. Realize that they may be affiliated with an IP address: 'username'#'ipaddress'. So that user can only connect for a particular IP.
- Check the bind address setting. In newer versions of mariadb, it should probably be commented out. I'm not sure about older version and pure mysql.
- other troubleshooting.
So after that's working, here are the settings which worked for me in MySQL:
go to Get Data/MySQL database/connect
Server: ipaddress:3306 (include ":port#")
Database: dbname
PowerBI interface. Select "Database" instead of "Windows"
Make sure you select Database instead of Windows.
Good luck.
Just a small tip. If you haven't already, restart the machine you just installed the connector on. I had to restart before it started working.
My solution for this was to add the port number to the server name/ip
eg. 192.168.0.1:4664
I am trying to connect mysql database in phpmyadmin to the access file. I am using mysqlconnector ODBC for that. Tutorial I am following is this
The problem is that when I give the credentials to connect to database, it gives me error as shown in this snapshot
I have tried hard to search on internet but failed. What mistake I am doing. I am putting the ftp information of the server there. Is there any database credentials i need to put?
You can't use the FTP credentials to connect the MySQL database. You have to use the database credentials. Make sure you have done followings before connecting.
Make sure MySQL server is up and running on the HOST IP and PORT.
Your MySQL server can accept connections from your IP or use % for
all IPS
Make sure you have a valid USER account
EDIT
Or tell us where(local server, internet, IP) the MySQL database is installed. The port number the server is listening on. How you access MySQL server normally.
I'm trying to connect MySQL Workbench to an Amazon EC2 (Linux) instance that hosts a MySQL Database. (Not RDS but localhost). However for some reason, I can't get it to connect remotely.
Things Ive done:
- Set the security group to allow any IP to access port 3306
- Created a mysql user and granted all privledges on it.
- Modified the my.cnf to include bind-address=0.0.0.0 However i still cant connect.
On this instance I do have SSL cert installed and I am forwarded all http request to https?.. But im not sure if this has anything to do with it.
If anyone could guide my in the righ direction I would appreciate it.
I would personally give it an Elastic IP so it will have a public IP, then bind the mysql to that IP. Make sure the iptables are set to accept the mysql connections. I also wouldnt suggest leaving mysql open to every ip unless this is an absolute necessity.
