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.

I have windows and am running ubuntu 16.4 on a virtual machine for my analysis, I have installed and created user login and password to mysql databank through VM using this instruction:
https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-20-04
but now I don't understand how I can connect to it with my windows browser? Is it even possible to connect to mysql from my windows because technically I have installed it on another system (VM Ubuntu 16.4)?
I would appreciate if someone could guide me since I am a beginner. thanks
You don't connect to a database server like MySQL using a browser, but rather with a dedicated client program.
Some installations of MySQL also have a web program running called phpmyadmin. You can use that web program from your browser to do things to your MySQL server. But the digital ocean tutorial you followed doesn't install that.
You need a MySQL client program running on your Windows machine to connect to the MySQL server on your VM. Ansgar Becker's HeidiSQL is a good choice. So is MySQL Workbench from the MySQL team.
And, be sure you can ssh from your Windows machine to your VM before you try all this stuff. You'll need to know the IP address of your VM when you connect to your MySQL server from your MySQL client.
Let's say your Windows machine has IP 192.0.2.101 and your VM has IP 192.0.2.121. You need to follow the steps in this part of your tutorial to create a MySQL user profile that can connect from your Windows machine. Something like this.
CREATE USER 'xyz0o'#'192.0.2.101' IDENTIFIED BY 'someHardToGuessPassword';
FLUSH PRIVILEGES;
To create that user you need to ssh into your vm and run the mysql command line program.
Then from your client on your Windows machine you'll connect to the MySQL server on 192.0.2.121 using whatever username / password combination you gave in the CREATE USER command.
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'm trying to connect my local MySQL to a test 2nd generation MySQL instance on Google SQL platform using the following command on my windows laptop.
mysql --host=130.211.xx.xx --port=3306 --user=root --password
I double checked my IP address with whatismyIPaddress.
I can connect via Google Cloud Shell on the Google Platform itself and also ping the IP address from the local cmd prompt.
As a troubleshooting step I have disabled the local firewalls on my laptop and granted full access to 0.0.0.0/0 to allow all connections on the google platform console.
still no joy from either a cmd line connection on windows or using a putty client, can anyone give me any further pointers on the missing step?
Cheers..
If you are behind a NAT your IP might change which prevents you from accessing the Cloud SQL instance. I would recommend setting up access using SSL certificate. More information about the setup can be found in this Help Center article.
You may need to allow remote connections to your remote database in the server and database configuration. These kinds of connections are typically disabled by default.
I have tried many ways to debug my remote server but I am unable to do so. My ftp and sftp and remote db is configures to my phpstorm 9 but I cannot debug my remote server it is connecting to my mamp server and debugging ,y local files but not connecting to server username and password . Basically it fails at mysql_connect but works for mamp.How can I make it deubug with server.Everything else is synced with server but I cannot debug. I really appreciate any help.
Edit: Should I install x-debug on my server(cpanel) also ?
php.ini
[xdebug]
zend_extension="/usr/local/opt/php55-xdebug/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.idekey=PHPSTORM
xdebug.remote_connect_back=1
Maybe I didn't understand your question/problem. These are the ways you can debug your code
Debug the local code that uses the local database
This is the easiest setup and it probably already works on your system. You have all the files on the local computer and also you have an instance of MySQL running on it. The code connects to localhost:3306, the xdebug extension is installed and it can connect to PhpStorm, everybody is happy.
Debug the local code that uses the remote database
You can have all the PHP files on localhost and use the local mamp stack to debug it; you control the environment, xdebug works and happily collaborates with PhpStorm. You want the code to be able to use the remote (live) database.
In this case you need a way to access the database. Either you create a MySQL user that allows you to connect from the IP address of the local computer (a firewall along the way might prevent this), or start a ssh session that creates a tunnel from the local port 3306 (or any other open port you choose) to port 3306 of the database server (assuming the host where you ssh is allowed to connect to it). You can do this by running
ssh user#remote_host -L 3306:database_host:3306
(replace user, remote_host and database_host with your actual values)
If you have a MySQL server installed and running on localhost then the local port 3306 is not open and ssh cannot use it as the source port of the tunnel. Use another port instead (let's say you use 13306):
ssh user#remote_host -L 13306:database_host:3306
Modify the local configuration files of your application to use localhost as database server and 13306 as database port.
Debug the remote code
If you want to debug the live code (it uses the live database) then you have to upload the code on the web server (the live environment) and make it work there (be able to connect to the database etc).
In order to be able to debug it you need to have the xdebug PHP extension installed on the server and properly configured in the server's php.ini configuration file.
The debugger (the remote xdebug extension) needs to connect to your local computer where PhpStorm is listening on port 9000. This is either impossible or making it happen requires changing configuration here and there in several places (that might be out of your control); we better forget about it.
We can use the ssh tunnel trick: start a ssh connection to the server that creates a tunnel from local port 9000 to the servers port 9000:
ssh user#remote_host -L 9000:localhost:9000
Test if it works
PhpStorm provides a tool that uploads a script on the web server then tries to access it to check if the xdebug extension is properly configured. Depending on the version of PhpStorm you use, you can find it either in the menu (Run -> Web Server Debug Validation, on PhpStorm 9) or somewhere in the Settings (PHP -> Servers or around, on older versions).
Is it possible to do the following?:
I have a local Mac running OS X Lion with a MySQL Server installed which runs different processes regularly and stores data into a local DB.
On the other hand I have an Amazon EC2 instance.
What I would like to do is to use the Amazon instance to perform certain cronjobs (using its own resources) but connecting to the data that is on my localhost (my computer) and performing basic SQL actions like updating the data, inserting, etc.
I don't know if this helps, but I have a static IP. Is there any way I can "open" my IP so the Amazon instance can recognize my home computer as a valid MySQL server?
Thanks for your help, any tip in the right direction will be much appreciated.
If your EC2 instance is connecting to your local db you'll need a static IP locally. Well not need... but if you don't have it anytime you reset your router or loose power etc your ip will change. You can look into Dynamic DNS as well for your local instance.
Your ISP will not block your port on your local instance. This would be a firewall inside your network that is preventing you from connecting to mysql or a configuration with mysql itself. Users can only connect to mysql from certain IP addresses.
You would have to open up the mysql port on your firewall if you are using one, have the mysql client installed on your EC2 instance, and make sure that the user that had proper grantable permissions.
That said why not run cron locally on the mac?
If you can login to your server via SSH then there's no need to open any other port and no static IP is required. You can use SSH port forwarding instead. From your local machine run:
ssh -C -R 5555:127.0.0.1:3306 <your-server-host>
Now you should be able to connect to your Mac's database running on localhost:3306 from the remote server at localhost:5555.
