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

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 have a MySql Server 5.7 running as service on one computer of a LAN.
My application is installed and running fine on the same computer. I have 'Shared with everyone' set for the directory where my application is located. In the same directory I have put the libmysql.dll and the FDConnectionDefs.ini files.
My application is running fine on that computer. On the other computers on the LAN I created a link to the directory where my application is shared. When I try to run my application from these LAN systems they produce the error message
[FireDac][Phys][mySql] can't connect to mySql server 127.0.0.1 on port 3306... (10061).
All machines are running Windows 10 on 64 bit processors.
Here what i've tried to resolve the problem:
make sure that the user, password and host (%) are the same in mySql Profile and FDConnectionDefs.ini.
I've tried with different users even with root, i've tried to change host (%) to put the IP address of the computer trying to connect in the mySql profile.
I make sure that i have permissions to run my application and mySql and that the port 3306 is open in the Firewall/Kaspersky on each computer of the LAN. But always the same error message.
127.0.0.1 is a special IP address - the "loopback" address that is typically resolved for localhost on most systems. It is a private internal IP address that a computer can use to refer to itself. It has no meaning to other systems on a LAN since every computer will recognize 127.0.0.1 as meaning itself.
This means that when you are running the application on a remote system it will be trying to connect to a MySQL server running locally rather than on a server elsewhere.
You'll need to configure your FireDac components to connect to the actual LAN IP address that belongs to the system hosting the MySQL server. You will probably also need to make sure that your MySQL users are set up to authenticate from an IP other than localhost.
I have installed MySQL on Ubuntu using SSH and would like to connect phpMyAdmin installed on a Windows machine.
I tried to add a server like standard server, but I can not log in to MySQL server using SSH.
Does phpMyAdmin support to connect a remote server using SSH? If yes, how can I configure a private key for phpMyAdmin or do I need a SSH client for this?
I think there's a bit of misunderstanding that might be hindering you sorting this out.
SSH is the Secure Shell protocol, which allows a user to remotely access the command line of a server. You can access MySQL via SSH by using SSH to start a command line session on the server and using the mysql command line client as if you were at the machine directly.
phpMyAdmin can connect to a local MySQL instance (where MySQL and your webserver run on the same machine) or connect to another machine through the network (where MySQL is running on one machine and your webserver is running on another -- the connection in this case is via the the port used by MySQL itself, 3306). In either case, you can access phpMyAdmin itself from any browser on the network; it just appears as any web page. The communication between MySQL and phpMyAdmin can be encrypted (via SSL) if you wish, but still happens via MySQL communication and not over SSH. At no point is SSH used for the communication from the web server to the MySQL server.
So in your case, since you wish to install phpMyAdmin on the Windows box, you'd simply edit your config.inc.php to connect to the IP address or hostname of the Ubuntu server with the $cfg['Servers'][$i]['host'] = 'hostname'; directive, using the actual hostname instead. You'd then access phpMyAdmin from anywhere on the network by using the hostname or IP address of the Windows machine.
If, instead, you wish to install phpMyAdmin on to the Ubuntu machine, you could use the host name 'localhost' in config.inc.php and then access phpMyAdmin from the Windows machine (or any other machine) using the Ubuntu IP address/host name in your web browser.
It all depends which machine you wish to be the web server. phpMyAdmin runs under IIS or Apache runs under Windows, but Ubuntu makes installing all the programs easy through the package manager, so that's what I generally do in this situation.
Hope that helps clear it up a bit.
