I need connect mysql via ssh - mysql

is there a valid extension for connect mysql via ssh on visual code studio?
I can't find nothing!;
I've been tryed with Mysql managment tool but seem there are not options for ssh

I guess you mean that you want to connect to MySQL via an SSH tunnel.
I don't know any specific solution for visual studio code, but if you have an extension to browse your database (and it doesn't support SSH tunneling) on its own, you can just create a ssh tunnel by yourself. Just run:
ssh -L 3306:127.0.0.1:3306 user#remotehost
And keep that session opened for the time you want to use your DB. Point your DB browser at 127.0.0.1:3306 and that's it.
Keep in mind that 127.0.0.1 in the example is the host you're tunneling TO, so if your MySQL server listens on, say, 1.3.3.7, just do -L 3306:1.3.3.7:3306.

Can't connect to mysql server (LAMP) in google cloud

I installed LAMP on a VM instance on Google cloud but when i try to access mysql database remotely from my linux terminal using
$ mysql -u username -h ipaddress -p
after entering password nothing happens (no error). I tried accessing it locally via ssh it works.
Is there any other setting on cloud platform. I need to change before accessing database from a remote pc. Followed this tutorial but it just stops after entering password.
Tried commenting out bind address but didn't work. Need help.
Just to be clear, are you using the mysql command on your remote machine or through SSH?
Normally, you should never allow external access to remote MySQL for security reasons, especially if the only app accessing the data is local. (however, it's unclear if that is the reason why you can't connect)
This is how you should connect:
Connect to your remote VM using SSH (ex: ssh user#ipaddress)
THEN, connect to your MySQL instance.
When connecting using a DB editor, some editors allow MySQL connections through SSH. Sequel Pro for Mac does this very well.

How can I connect a Jupyter Notebook to a remote MySQL DB using Peewee?

I am trying Peewee to connect and retrieve data from a MySQL remote database, but I get the following error:
InternalError: (1130, "Host 'x.x.x.x' is not allowed to connect to this MariaDB server")
Could you help me?
"retrieve data from a MySQL remote database"
"Host is not allowed to connect to this MariaDB server"
Seem to point on a simple problem:
You're not allowed to connect on the DB from "outside".
By default, MySql / MariaDB are only listening on the "inside" of the server, from MariaDb doc :
MariaDB packages bind MariaDB to 127.0.0.1 (the loopback IP address) by default as a security measure using the bind-address configuration directive.
This mean apart for an application that run on the same machine (accessing 127.0.0.1 or localhost), you'll not be able to connect.
Solutions:
SSH tunnelling
This is probably the safest way to allow a connexion on a remote DB.
SSH is a protocol that allow you to connect to a server. It's mainly used on unix server to manage them, but can do a lot more.
How to use it in your case?
if you can connect with SSH to your DB server, then running this simple command on your notebook the will do the trick:
ssh -L 3306:localhost:3306 user#x.x.x.x
Lets explain a bit: first, your run SSH, then, you tell him to enable a port forwarding from your 3306 port to the localhost:3306 port of the server you connect through user#IP.
With this command running, every query from your local machine:3306 will by send to your MariaDB:3306 server, allowing you to use it as if you where on the server.
Allowing a remote-access user
This one is way more dangerous than the previous one. You'll need to take your time and think about every outcome it mean.
As already said, you're not allowed to connect from outside, ssh let you be "inside", but if you know what you do, you can just remove the security.
The point is:
to make an account that'll be able to login from a remote IP,
allow MariaDB to listen on external requests,
and at least, secure other account to disable remote connection.
[I'm not putting the how-to now, if you really need it, I'll update this answer]

Remote access to local MySQL

I want to connect to MySQL. Unfortunately target server is accessible only from localhost. It is able to work around for example by uploading some PHP script on the server? I mean a single file rather than the entire PHPMyAdmin or something similar.
can you please elaborate more about your issue?
If you want to connect to mysql server remotely then you need to grant user in mysql users table with your local system IP range.
You could look at using ssh to tunnel the connection through your local host .. Will need to know a bit about your network layout
http://www.howtogeek.com/howto/ubuntu/access-your-mysql-server-remotely-over-ssh/
ssh -L 3306:localhost:3306 geek#webserver.com
you can use ssh tunneling for that here is a link
ssh -L 3306:localhost:3306 root#remote-mysql
The syntax is
ssh -L <localport>hostname<remoteport> <username>#<servername>.
We’re using localhost as the hostname because we are directly accessing the remote mysql server through ssh. You could also use this technique to port-forward through one ssh server to another server.

Workbench migration via ssh - how to set up a tunnel

I try to migrate MSSQL (local machine) to MYSQL (Amazon Web Services) usin Workbench. I can connect to both databases. However when I migrate I get this error:
Mysql connections through SSH are not supported in this version...
Well, I found this in documentation:
A workaround is to set up an encrypted tunnel, and then treat the MySQL target as a standard TCP (unencrypted) connection.
But I don't know how to set up a tunnel. Does anyone can help?
Okay, if I'm understanding this correctly, I think I'd prefer to set up a tunnel in Putty. I don't have a solid grasp of how MySQL Workbench works (I'm assuming its analogous to SSMS), but I have used maaany SSH tunnels in my day. Here are some basic instructions:
http://www.electrictoolbox.com/putty-create-ssh-port-tunnel/
You'll want to create a local tunnel from any port you choose (although I'd go with the MySQL default 3306) to the destination of 127.0.0.1:3306. Be sure to click add and save your session settings in Putty.
Open the SSH connection to the AWS machine. Try to connect to your MySQL instance through 127.0.0.1:3306. This should allow you to pull from your local SQL Server and send data to your AWS instance (through the tunnel, 127.0.0.1:3306 of course).
Hope this helps. Let me know if this doesn't solve your issue.
If you have Amazon ec2:
On Windows machine connect using putty via ssh:
In session host name (user#public_ip_address)
Connection -> SSH -> Tunnels (Source port: 3306 OR choose free one) AND (Destination 127.0.0.1:3306)
You can check if tunnel was establihed in event log (right click on terminal bar)
In Workbench now you can use TCP/IP without SSH.
Thanks guys!

Can I SSH to MySQL with the GUI tools?

I have a ubuntu server which I've locked down to only HTTP, HTTPS and SSH (port 30000). On this box I have a MySQL server which 99.9% of the time is only used locally. Every now and then I want to connect to the MySQL instance with the GUI tools, but without touching the firewall.
Therefore, it is possible to set things up so that I can connect to the MySQL box with the SSH connection? Is there any sort of port forwarding magic I can do?
ssh -L localport:127.0.0.1:remoteport user#remotehost
where localport is an unbound port on your local system, remoteport is the port on which MySQL listens, 127.0.0.1 is the loopback address on your remote system, user is your user name and remotehost is the address of the remote system.
Then point your MySQL client to 127.0.0.1:localport. The connection will be forwarded over the SSH tunnel to the remote port.
If you are using Windows or Unix on your local machine, PuTTY is an excellent tool for this. Here's a tutorial on port forwarding:
http://www.cs.uu.nl/technical/services/ssh/putty/puttyfw.html
Set up a tunnel using the SSH client to map a local port, through the tunnel, to a port on the remote machine, then connect to the local port using the client.
man ssh will have the gory details, but you're probably better off searching the web for something a wee bit easier to read.
I'd suggest using HeidiSQL if you are on Windows. It handles the SSH tunnel by itself (you just need to download the plink.exe utility).
In my humble opinion, it is the best MySQL tool out there (and it's free and open source).
There two ways to use the GUI mysql tools on a remote MYSQL machine.
I'm assuming the remote machine is running linux.
Option 1.
SSH port forwarding.
ssh -L 3306:proxy:3306 username#remotehost
Basically you forward port 3306 on your local machine to 3306 on your remote machine, then you tell your graphical MYSQl tool to connect to localhost:3306 and you assume that your remote machine is listening on the standard port of 3306
http://magazine.redhat.com/2007/11/06/ssh-port-forwarding/
Also ssh -D 3306 username#remotehost should be similar
Option 2.
If you are running xserver on your remote machine and have the GUI tools installed on your remote machine you can tunnel your GUI over the SSH connection.
ssh -X username#remotehost and then start your GUI tools over on remote machine from the command line.
SSH/HTTP tunneling in SQLyog is good. There is public/private key authentication which adds an additional layer of security.
I suggest looking to phpMyAdmin a web based tool to administrate MySQL, and is very good (requires PHP). It can be installed through the normal Ubuntu methods (e.g. Synaptic)
Or do X tunnelling with SSH as mentioned above.
