Our company has a database server on AWS which other the employees can connect to it with MySQL, but when I tried, I got this error message, how can I solve it?
I tried to reconfigure MySQL server but it didn't work. also I double checked username, password, url and port.
To connect to an RDS MySQL instance from MySQL WOrkbench on your dev machine, check a few things.
First, get the full endpoint to the database from AWS Management console.
Ensure the database is publicly accessable.
Also, make sure that you set up your inbound rules correctly.
Once you do these things, you can use MySQL Workbench to connect.
In the hostname field, make sure you put in the hostname you copied from AWS Management console. Do not put in extra information such as:
dbc:mysql://forxxxxxxxxxxxxx.us-west-2.rds.amazonaws.com
make sure it is:
forxxxxxxxxxxxxx.us-west-2.rds.amazonaws.com
THen specify the user name and password and MySQL Workbench will connect:
I use docker-compose.yml to deploy MySQL, InfluxDB and Telegraf. I want to write the data of a MySQL database to an InfluxDB database through Telegraf. How to set the dsn of [inputs.sql] plugin while using telegraf to connect MySQL? Here are my settings:
It is said the dsn should be set as followed:
username:password#protocol(address)/dbname?param=value
My config turn out to be wrong:
E! [telegraf] Error running agent: starting input inputs.sql: connecting to database failed: dial tcp 192.168.48.5:3306: connect: connection refused
Can you tell me how to fix it?
Thank you very much.
Looks like there is connection issue there. Could you first test your MySQL connection from where the Telegraf agent is deployed?
Open a terminal from where the Telegraf agent is deployed
From inside the command prompt, type the command telnet 3306. In your case, that would be:
192.168.48.5:3306
Hit enter to activate the command. If the MySQL service is running, you will receive a response from the server. If not, please make sure the MySQL is up and running and the firewall is clear.
I am trying to use R-studio and R script to connect to mysql database which is on an Ubuntu system. The error is:
Error in .local(drv, ...) : Failed to connect to database: Error: Can't connect to MySQL server on 'x.x.x.x' (0)
I tried using telnet to connect, but I get an error saying:
Could not open connection to the host, on port 3306: Connect failed
I tried using putty, and I am able to connect to the ubuntu system with proper credentials. But I am unable to connect thru R. Windows firewall has been disabled. Password and IP address are fine. I tried using localhost but no help.
Any suggestions would be greatly appreciated.
I figured out. there were some internal issues, otherwise, everything as fine. the port was open and the password was right..
I've confused about this problem, and still stuck out of it for a week.
I've trying to federated table in mysql, but when tried to do query select to remote table. I got this message
Error Code: 1429. Unable to connect to foreign data source: Host '172.25.97.136' is not allowed to connect to this MySQL server
while 172.25.97.136 is my ip static address not remote server's ip address
i've read this solution Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server But still didn't work.
anyone can help, please?
Can you check, are you able to connect to that mentioned ip using mysql as,
mysql -hXX.XX.XX.XX -u -p
If you are unable to login with above command,clearly it is a permissions issue.
Please check.
Thanks,
Lakshmi
When I try to connect to my MySQL server using MySQL Workbench - I get the following error:
'Error Connecting to Server (root#ipaddress)
Could not establish SSH connection: Error reading SSH protocol banner.'
Has anyone experienced this issue before? I would love a pointer!
Solved this issue.
The issue was that I was trying to connect to the SSH port instead of the MySQL port. When using this over SSH connections - you want to configure the SSH connection, and make sure you connect to the 'MySQL' port, since this is a pseudo-VPN connection.
