Allow Remote Mysql To Centos Server - mysql

I have a development server in my office, which runs through my domain server with routing.
Everything is fine, however i cannot connect to the development server mysql remotely.
The dev server is with ip 192.168.1.3 on the subnet in the office. I can ssh to it, reach apache and ftp. But mysql says: Host "192.168.1.2" is not allowed to connect to this MySql Server"
any help is appreciated. the ports are open on the firewall.

Unable to connect to MySQL installed on another virtual machine or over network

I have several vms instances running in my vm player. Several of them are cent-OS acting as HTTP servers. The HTTP server is/are accessible over network. The HTTP server is on nginx.
Then I have a vm running on cent-OS having MySQL installed. And another vm instance running MS Server 2019 having MySQL Installed. Am using MySQL 8.0.18 on both these machines.
All these machines are on same sub-net and gateway. for example the IP of one of my vm having HTTP server is 192.168.0.133. And the machines with cent-OS having MySQL Server installed is having IP 192.168.0.140 and machine with MS Server 2019 having MySQL server is having IP 192.168.0.141.
Now the issue is am unable to access any of these MySQL servers from the network(LAN) or in other words am unable to access the MySQL server running on either .140 or .141 from the machine .133 meanwhile am able to access the HTTP server across the network.
But if I running MySQL server on the same machine having HTTP server. There occurs no problem whether I use 127.0.0.1 or localhost in my db host configuration
My application is based on a PHP framework known as laravel.
I have disabled firewall from both the above machines. The port 3306 is open on both machines. Am able to ping all machines with each other.
I had tried things like:
skip-networking(commenting out this one or just deleting),
bind-address(IP of the machine running MYSQL server),
grant privileges on an ip or from any IP to users/user,
flush privileges
Even modified iptables.
Am entering db host as the IP of the machine where MySQL is running.
The error am getting is SQLSTATE[HY000] [2002] Connection refused
You've nearly done it all right. Setting bind-address to the server's IP however means that you must connect via SSH.
Change the IP to 0.0.0.0 and restart MySQL, and hopefully that should be you all set.

cannot connect remotely with online database on localhost phpmyadmin

i have configured the phpmyadmin's config.inc.php file and a drop down menu has appeared accordingly in localhost/phpmyadmin to select the server. But when i try to connect to the server it says:
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.
i have added my ip address to the online host server in the cpanel and have access to the remote sql connection.
please help.
Most hosts block incoming connections to the MySQL server as a security measure. You'll have to ask your host about unblocking port 3306 and how to access your MySQL directly -- or run an API on your web host, which would have access to the MySQL server due to being on the same network, and access the database through that. For phpMyAdmin specifically, just install it on your web host instead of your local machine, then access it through the internet rather than localhost.

"Can't connect to MySQL server", only when client is remote server

I'm having a weird problem where I can connect to a certain database server from my local machine (and my friend can also connect to the database server from his local machine) but we can't connect to the database server from his AWS server.
What I get on the AWS server is:
"Can't connect to MySQL server on '<IP address>' ".
It's not as if the database server is only allowing connections from certain IP addresses; it didn't know about my IP address before I tried to connect.
Any idea what could be different about my AWS machine that could be making the connection not work?
Is the MySQL server inside the same network as the local machines? If so, it might explain why local machines can connect but the remote AWS can not.
By default, MySQL disables all remote connections. You can check if the remote connections are enabled. It could also be an issue with port block. MySQL uses port 3306 by default. Either MySQL or the AWS might not be configured to send data through the firewall on port 3306.
Here is a decent article explaining how to open these things up.

connect and fetch remote MySQL server from Mac

I ma following this tutorial on how to connect to a remote MySQL server, however It seems the command doesn't work and often results in Operation timed out when trying to connect to the server:
ssh mysql.xxxxx.com
I can connect directly from my hosting account but not through the Shell on my Mac OS.
There may be a firewall or other network security device in place that prevents you from being able to connect from your Mac. Also, it is possible that the MySQL server is not configured to allow inbound network connections.
You might ask your hosting provider if they filter access to the MySQL port (default is 3306), or if your host is pre-configured with a firewall, and you might check your MySQL configuration file to ensure it is listening for inbound connections.
When you ssh into a remote server, and you do not specify a user name, ssh defaults to your current user.
bobs-macbook-pro:~ bob$ ssh server.acme.com
is the same as:
bobs-macbook-pro:~ bob$ ssh bob#server.acme.com
Try using your username when 'sshing' into the remote mysql machine.
There are two ways to specify your username, either one should work.
1. bobs-macbook-pro:~ bob$ ssh bob#server.acme.com
2. bobs-macbook-pro:~ bob$ ssh server.acme.com -l bob

Having issue accessing mysql server from other machine

I have installed mysql server and workbench on a machine that is running on Ubuntu Linux platform.I also have installed mysql server and workbench on my machine that is running with Windows 7 OS.Both the machine are connected to network.I want connect to the mysql server from my machine.i tried changing the bind address of mysql server according to the machine's ip, and gave that ip as host name while connecting through mysql workbench from my machine.But i am not able to connect successfully.Please Help
Well, IMHO, the only problems that could be are ither:
Username does not have enough priveleges
Server does not accept connections
Firewall Blocking port
You should investigate each of these cases
