I installed a new mysql server into an amazon ec2 instance. My instance is configured with a domain name protected by an amazon ssl.
All works perfectly:
My wordpress is running under an https.
I configured mysql to perform remote connection and I can connect to it with intellij using the IP_adress:3306
But I can't connect to remotely using the domain name:
This is how I configured the url into intellij: jdbc:mysql://mysiteweb.com:3306
And this is what i obtain as error:
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
java.net.ConnectException: Connection refused (Connection refused).
Have you point your domain to the server's IP address ?

I am working on deploying my Django project on Linode. My MySQL database that I used during development was on a ubuntu server that I have at my house. This was different that the computer I wrote the program on. In the settings.py file I had the database connections set up and working. On my personal server at home I have updated the UFW to allow the new linode ip address and granted privileges to the ip address also. When I go to run the server on deployed project on linode, I get an error (2003, "Can't connect to MySQL server on 'personal server ip address':3306' (110)").
How do I get the linode server to be able to talk to my personal server's MySQL database?
Iiuc, you are trying to connect from linode to your home server - this is an odd configuration and will be problematic
what you need to do is to allow incoming connections at the router level so that packets are not dropped via port forwarding - I think your router is blocking the incoming DB connection
But like Yevhen said - it is a better approach to have MySql in Linode directly
I have a VM (OS: Ubuntu 18.04) running in azure cloud in which I have installed docker. In docker I have two containers MySQL(8.0.20) and node-red(v2.1.3), I am trying to connect my MySQL with node-red and I get the following error message in Node-Red
"Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client"".
MySQL is working fine, I am able to access the database via putty but somehow I am not able to make a successful connection with node-red as well as Grafana.
I am using following configuration. My VM's IP address is 20.107.194.152 and MySQL port is 3306
Can some one tell me what I am doing wrong here. Thanks.
I am trying to connect to db server from ETL servers through SSIS package. Connection is not working from any ETL servers through SSIS. Below is the screenshot. Please let me know what I am missing.
We also performed a test with the telnet client and test was successful.
Error Message:Test Connection failed because of an error in
initializing provider. Client unable to establish connection TCP
provider. An existing connection was forcibly closed by the remote
host.
Restart all SQL Server services
Check if SQL Server browser is running and SQL Server is configured
to allow remote connections.
Check your SSL and TLS settings from the registery settings. The settings between the client and server should be logical and consistent (i.e. if the server only allows 1.2 and the client only supports 1.0)
I am new to setting up SSL certificates on servers and would need some help to secure a MySQL database connection. I have a simple mobile app (client) which needs to connect to a remote MySQL database (server) connection. I am using AWS EC2 for the remote server and I have installed Let's Encrypt SSL certificates on a domain that I am hosting there. The machine runs on Ubuntu 18.04 and NGINX.
The same server also runs a MySQL database and I want to connect to it securely using a mobile app client. How can I encrypt the connection between the mobile app aclient and the MySQL database server?
I do have a static ip address for the database server but I am unable to install SSL certificates on the ip address directly. Only the domain name has an associated SSL certificate.
I did some digging around but was unable to find anything that serves my purpose. Any suggestion or reference to an article would greatly help.
This article provides a detailed step by step procedure for securing the connection between a remote MySQL database server and a client.
Securing a remote MySQL database server connection
We have a small network behind a firewall (WatchGuard XTM 2 series) and network switch. On our network we have multiple instances of SQL server, but 1 in specific that I would like to be able to access remotely from our website. We have a static IP address from our ISP and then all the machines on the network have a locally assigned dynamic IP address. When trying to connect to the database from outside our network how do I get the request to be directed to the proper machine / SQL instance? Is it a parameter in my connection string or something in my firewall?
A few things to rule out:
1) The firewall is allowing access from the website to our network. I added the site's IP and opened up port 1433. Also, when trying to connect and monitoring the firewall no exceptions come up as they did before I added the proper IP address.
2) Remote connections on the SQL server has been setup and enabled. I've done a lot of reading up on remote connections and I am sure it has been setup properly.
I am currently getting this error message on my site:
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: TCP Provider,
error: 0 - A connection attempt failed
because the connected party did not
properly respond after a period of
time, or established connection failed
because connected host has failed to
respond.)
The Server parameter of the ConnectionString indicates what server to connect to. Assign an ip address or URL to the server that you want to access and put that in your connection string.
