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 need to connect to remote mysql on different server and my nodejs code is deployed on google cloud. I have tried with host ip, username password of remote mysql, but giving following error:-
{"errorno":"ETIMEDOUT","code":"ETIMEDOUT","syscall":"connect","fatal":true}
ETIMEDOUT is a Node.js networking error. You will need to tinker with you firewall rules to allow the connection.
Probably opening port 3306 will solve the issue. Here's the documentation for setting up a remote access to MySQL [1] and the networking side [2]
I have working WebAPI in .net core in Docker. I want to deploy this API on AWS EC2 instance with local mysql database working with other web app.
How can I reach this Mysql from inside docker?
Locally I can do it by using my private ip addres in
=> optionsBuilder.UseMySql(#"Server=$my_local_ip;database=db_name;uid=user;pwd=pass;");
Ho to determine which $my_local_ip should I use in order to connect to DB?
But while using the private ip on EC2 I got error while sending request that it can't connect to any MYSQL host.
For MySQL server you generally have to specify the port to connect to, as each instance on the same server uses a different port.
Use --network=host flag while starting the Web API container and use the localhost in you connection string as the host name. This will enable the Docker container to access the host network. Hence you can access MySQL Database from the container.
Note: This is an insecure for running containerized workloads. Click Here to learn more
I am pretty new to aws stack and trying to setup a simple node-mysql app.
Node is running on AWS EC2 Ubuntu 14.04 instance, and MySQL is running on AWS RDS instance.
I am trying to connect to MySQL from my Node client using popular MySQL connector https://github.com/mysqljs/mysql but for some reason always getting 'Connection timeout'. Since node connection doesn't work, I tried to connect using a Telnet just to see if I at least can create any kind of connection.
telnet instance.12345.amazonaws.com 3306
but also unable to connect. Please note both of the connections e.g. though node app and through telnet do work when I try running them from my Windows localhost.
Things I've considered:
EC2 Ubuntu instance has Outbound rules to allow any kind of out
request.
Running app as sudo.
RDS MySQL instance has inbound
port 3306 open.
Installed MySQL client on my EC2 machine.
Basically have no idea on what exact step I've missed during setup and just trying to poke anything possible, any help/suggestion is greatly appreciated.
I have purchased a Azure VM(Ubuntu 12.4) and setup-ed MySQL server in my VM . My problem is like when i tried to access mysql db from my local Azure Vm machine through Workbench its working fine, but when i try to access it from an external server which is outside VM i am getting some error.
I have opened Endpoint in Azure VM for port 3306, still its showing error.
Is there any setting i need to change in My Azure VM to enable remote access.

Any help is appreciated..
I recently deployed a .war from Netbeans IDE on my local machine to Amazon EC2. The Servlet in my Webapp used JBDC Connector/J, the jar file for which was copied into Libraries in Netbeans. The WebApp was working well on my local machine. But the logs of Tomcat on Amazon EC2 shows an error the host 'xyz' is not allowed to connect to this MySQL Server.
confirm host information for mysql - run this on mysql:
select host, user from mysql.user;
If your host/port information is correct, try checking privileges being used for the web application. Also, make sure that your database server is able to bind on the specified port (netstat -an | grep 'port number') & that the client app can connect to that port (on the host). hope it helps
