I'm using Outsystems Service Studio to develop a web application. I need to configure a connection to access a local server database. I get "Connection String test failed: Unable to connect to any of the specified MySQL hosts." I just figured out I can't connect using "localhost", because the Outsystems server is not local, but I'm not able to find a solution. what is wrong? Other details:
MySQL Server is up and running
I selected MySQL in DBMS
Inserted my schema name
Inserted the username (with all privileges granted)
Inserted the user password
Tried both basic and advanced configuration. I inserted j"dbc:mysql://127.0.0.1:3306/mydb?user=outsystems2" as connection string parameters and I get "Connection String test failed: Keyword not supported.Parameter name: mysql://127.0.0.1:3306/mydb?user". I know this connection string can't work , but I'm not able to find a functioning one. I've read many guides about this configuration, but no solution was found. Thank you all for your time and help, feel free to ask for more details
Luciano,
Is your OutSystems environment on-premises or in the cloud? Either way, you need to make sure that this server is able to reach - it as connectivity - to your MySQL database server. Using localhost or 127.0.0.1 is pretty much the same thing as this is an address for the machine where the request is running, which is, in this case, the OutSystems server. Do you have the MySQL database on your local machine? This is not a good approach as you will need to have an address that won't change otherwise the connection won't be stable and you'd have to reconfigure it all the time.

I just opened an account on Amazon AWS. In this account, I created a mysql database instance, that I am now trying to connect to on my home computer use mySQL Workbench. I have entered the database endpoint (as listed in my account) and added the user name I set up for the master username for the database. When I hit "test connection" (using standard TCP/IP connection) however, I get a "Failed to connect..." message. I have a feeling that the problem may be that I need to use SSL and/or SSH. But I am a neophyte here, and I don't know how to properly set this up or configure mySQL Workbench with this. I am seeking assistance
You need to allow your mysql server to the user my user policy.
You can allow your Public IP address.
Please refer below case:
Cannot ping AWS EC2 instance
I think there that my database instance was misconfigured somehow, though not as JERRY suggests. I created a new MySQL DB instance and was able to connect to that without needing any other special configuration changes. So I am now using the new instance, and have deleted the old one. I wish I could provide more insight into what the problem with the first DB was, but the insight I have is (as I said) after I created the 2nd DB instance, no other configuration was necessary
Backstory, I would like to build shiny apps to give to some of our data collectors so they can review what has been collected. We currently house all of our data in a cloud based MySQL server. Ideally, I would like the shiny app to pull data directly from the MySQL server so it can be fully automated without any data pulls and up 24/7.
I have been trying to first just build the connection between R and MySQL using the RMySQL package and can't seem to get it working. I have set up a specific username/password for this connection that is read only(however I have also tried my regular username which has all privileges granted). This is the code I am running;
mydb=dbConnect(
MySQL(),
user='myuser',
password='mypass',
dbname='vgtg',
host='ipaddress',
port=3306,
)
Obviously the 'ipaddress' of the server has been changed for the sake of posting here but it is a generic looking address like
'192.168.1.1'
When I run the code above I get this error message;
Error in .local(drv, ...) :
Failed to connect to database: Error: Can't connect to MySQL server on
'ipaddress' (0)
I have tried looking for previous questions posted but none seem to be exactly this error message that I am receiving. It makes me think that for some reason RMySQL is looking locally for the server when it is actually a cloud based, remote, server.
Also, is there anything more I should set up server side to allow the connection? I do have a server admin to help out but I am not sure how familiar he is with R and likewise I am not particularly familiar with working with servers. He has opened port 3306 for me and is able to see my attempts to connect through the port.
Your syntax is correct with the exception of
port=3306,
You need to drop the comma. That said, the error you received is unrelated to the syntax.
Without knowing the details of your setup, it is hard to diagnose. Where does the MySQL DB reside? For example, if it is on an AWS RDS instance, then the host isn't a standard IP address, it is something like this
mydb.cm1abc2v4mod.us-west-1.rds.amazonaws.com
Assuming that the IP address you used is correct, then the problem is most likely on the server. You need to ensure that port 3306 is open to traffic. Otherwise, R will not be able to connect to the DB.
I have the following information to a SQL database
Server : MyUserName.mysql.db
User : MyUserName
Password : MyPassWord
I am a little noob in this context, so I have some questions:
How to know where is hosted my database? Is it in mysql domain? (Isn't that the type of database?)
How can I access it and visualize it?
To begin with, you need a CLIENT to be able to access your database. For MySQL, you can use either Workbench or MySQL CLIENT (the last giving you command-line level access).
Second, and according to your information, the server is MyUserName.mysql.db so if you try to PING that server you should get some response.
Third, MySQL has a default port number so you need to configure your client to access that server though that port (if I'm not mistaking, 3306).
You will also need access credentials to your database.
Your DB administrator should be able to provide all the information you need.
Contact your database administrator.
If you're trying to acess/visualize sql server database on your local computer install ssms to connect to your local database , similarly you can access any other database through ssms.
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 have a database on my server and I want to connect to it through MySql Workbench, I entered my HostName, Username, Password, When I click Test Connection I get this Error Message:
Failed to Connect to MYSQL at **.**.***.**:3306 with user root.
Host '**.171.199.66' is not allowed to connect to this MySQL server
I am 100% sure my Hostname, username and Password are correct, I did some research and from what I managed to find out that I have to actually permit an access from my IP address to the database before I can connect.....if this is correct could someone explain to me how to give myself e permission to connect to my database on server.
It is likely that your MySql root account is configured to not accept remote root logins (its a default). If you are trying to connect from anywhere but localhost its not going to allow it. Your're right you need to permit access for your IP. You need to do it from within the server your MySql is installed on. In case of if you have managed hosting, your hosting company should provide you with a tool like phpMyAdmin or such, to manage your MySql. If it is your own installation, you can connect to mysql server instance from the console and go from there.
