I am trying to connect HeidiSql from the host to my WSL Mysql but I could not get it to connect it
Error "can't connect to Mysql server on '127.0.0.1'"
Tried SSH too but could not connect to the server
I'm also hosting mysql-server on WSL and running MySQL workbench on Windows.
I had to get the IP inside of WSL
And use this IP in MySQL Workbench
By default, MySql only listens on 127.0.0.1. If you are connecting using the IP address returned by wsl hostname -I (as mentioned by Permana) then you need to change /etc/mysql/mysql.conf.d/mysqld.cnf to listen on all IPs or your specific IP.
Edit your MySql config by typing this in your Ubuntu instance:
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Change the line:
bind-address = 127.0.0.1
To:
bind-address = 0.0.0.0
or change 0.0.0.0 to the IP returned by wsl hostname -I.
Restart MySql using: sudo service mysql restart
Since your question is asked before WSL2 release, I assume you were using WSL1.
For WSL1
You can access WSL1 MySQL directly from Windows, but you were attempting access in a wrong way.
In the Network type, you should choose MariaDb or MySQL(TCP/IP) instead of MySQL (SSH Tunnel).
For WSL2
Check this WSL github issue. Save #edwindijas's powershell script and execute it by administrator. If you still cannot access MySQL and got access denied for user ... <you-computer-name>.mshome.net, you need to allow this user access from this host.
For example: let's say root, you need execute this in mysql cli:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%<you-computer-name>.mshome.net' IDENTIFIED BY '<password>';
Or allow root user access WSL2 MySQL from any host:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'password';
As for me who's also using WSL for making web based application
first make sure mysql is running on WSL like sudo service mysql start
then once started, open HeidiSql and simply connect to it, here the example on my part
make sure the IP address is 127.0.0.1 not any IP, not your IP used to connect on the internet

I have visited many websites for remote connection of MariaDb.
I have executed the command as below to create user with password in sql.
GRANT ALL PRIVILEGES ON . TO 'root#(my server ip)' IDENTIFIED BY '(my password)'
And i've added one line below [mysqld] in the file of /etc/my.cnf.d
bind-address = 0.0.0.0
Then restart MariaDb service as below
sudo systemctl restart mariadb
Everything runs good.
However when i access by below command, it runs failed.
mysql -u root -p -h (my server ip)
I've turn off my firewall in my server, and turn on the port 3306 in GCP server, and it can be expected, i must fail to connect in my local machine.
Since you want to use a TCP connection, I assume that you want to connect to a remote server, not to a server running on the same machine.
Make sure that you are able to connect physically to the database server, e.g. with telnet server_ip:3306.
Determine the IP address of the computer from which you want to connect to the server (= client_ip).
Add a user on the server:
GRANT ... TO root#client_ip
If client and server are running on the same machine, the preferred way is to use a linux socket (user#localhost) which is way faster.
I searched a lot but not able to solve that problem.
i am able to access MySQL server running on different windows machine. steps i have taken are
changing my.ini file bind address to 0.0.0.0
creating user and granting permission by GRANT ALL PRIVILEGES ON DATABASE.* TO user#'%' IDENTIFIED BY 'password';
from command line to windows MySQL server mysql -h windows server ip -u user -p
it works fine and from MySQL workbench i am able to connect for windows MySQL server from my machine. BUT when in Linux virtual machine i have done the same thing
changing my.cnf file and change bind address to 0.0.0.0.
creating user and granting permission by GRANT ALL PRIVILEGES ON DATABASE.* TO user#'%' IDENTIFIED BY 'password';
From command line to LINUX MySQL server mysql -h linux server ip -u user -p
but for that i am getting following error after giving password ERROR 2003 (HY000): Can't connect to MySQL server on 'linux server ip' (10060) also when connecting from c# by following connection string <add name="MySqlConnection" connectionString="Server=LINUX_VM_SERVER_IP;Database=database;Uid=user;Pwd=password" providerName="MySql.Data.MySqlClient" />
i am getting Error : Unable to find and specified mysql host
i have checked in LINUX_VM that 0.0.0.0:3306 is in listening status.
if i try to telnet LINUX_VM MYSQL Server service using />telnet
LINUX_VM_IP 3306 i got the ERROR : Connecting To
LINUX_VM_IP...Could not open connection to the host, on port 3306:
First, try to connect to the database on the VM hosting the database. If the connection is successful, then the configuration of the database is correct. Otherwise, please check the configuration of your database.
Second, if you are able to connect to database on the VM, then the most possible cause of this issue is firewall. Please check if the local firewall (iptables) allows inbound connection on port 3306. For test purpose, you may disable the firewall temporarily. Also, please check if the NSG has been configured properly to allow the inbound traffic on port 3306.
Besides, if the VNET has been associated with a NSG, then we need to allow the inbound traffic in the NSG too.
I have been using ubuntu 14.04 LTS OS and now i want to give permission of my local mysql server for my colleague system in my network. I need the answes for the following question,
How to bind my system IP address to mysql server. If i execute the command line "mysql -uroot -proot -h192.168.1.198", then received the error message below
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.198' (111)
Then how to give permission to other system user to access my local mysql server.
Your MySQL service is bound to serve localhost only (interface binding). This is the default for security reasons. If you really need to access it directly from other hosts, there is a nice How to enable remote access to MySQL on Ubuntu which you could follow:
as root, open your /etc/mysql/my.cnf with your favorite editor
look for the [mysqld] section, and in there for the bind-address keyword. This usually is set to 127.0.0.1 -- change that to match your "normal" IP-address
save the file, and reload the service (e.g. using service mysql restart)
Remember you must enable your remote users to access their database(s) from remote, by setting the appropriate GRANTs -- e.g.
GRANT ALL ON mydb.* TO remoteuser#'%' IDENTIFIED BY 'SomePASSWORD';
Note the #'%', which means "from any host".
Try to telnet MySql server from that PC
telnet 192.168.1.198 3306
If that fails there are two cases:
You have not properly opened MySql Server required ports (default: 3306)
Go to my.ini (or my.cnf) and comment out bind-address and change it to 0.0.0.0 (to listen to all available interfaces) or perhaps the server's LAN IP (192.168.1.XYZ).
Is it possible to connect mysql of my webhost from cmd on my pc, in the same way as I am connecting to mysql installed on my localhost using XAMPP.
You'll need to download and install the Windows MySQL client
http://www.mysql.com/downloads/installer/
After installation, make sure the mysql executable is in your cmd PATH.
You need to specify the hostname or IP address of the server with the -h parameter.
mysql -u username -p -h myhost.example.com
Yes its possible to connect to MySQL on web host. MySQL runs on port number 3306. You need to check if the web host has this port open. if not you can request your hosting provider to get it opened. Once its done you can connect to MySQL as you do on localhost May be you need to add privileges to user account to connect from remote machine(your localhost IP).
Other option would be to use PhpMyAdmin.
I have my dev environment set up as a Ubuntu Server (with LAMP installation) inside a vmware. The vmware is running on my local windows 7 machine. When I try to access my mysql server via HeidiSQL program the connection fails. I get a:
Server Error 2003, can't connect to mysql server on <IP ADRESS HERE>
I can however access the db server via PhpMyAdmin. MySQL is running and my connection credentials and port are all correct.
I read that you should enter the IPs of the computer you are trying to connect from as the "bind address" in the my.cnf file. Which I did. I tried both the internal network IP as well as the online IP. Still no luck, same message.
Since this isn't a production environment I would ideally like to allow anyone to access that server, not limit it by IP. Especially since my ISP assigns dynamic IPS. So I would have to change it all the time, assuming that even works.
So does anyone know how I can connect to my MySQL server from a remote computer?
P.S. I assume this is something developers have to deal with that's why I posted it here and not Super User. If it must be migrated please send it to Server Fault not Super User.
Ok, be aware this gives the world and his dog access to your mysql server.
GRANT ALL ON *.* to '%'#'%' WITH GRANT OPTION;
But say you are on your home network of 192.168.1.2/16 then you can at least limit it like this.
GRANT ALL ON *.* to '%'#'192.168.%' WITH GRANT OPTION;
Another option is that you have a user and password but want to connect from anywhere
GRANT ALL ON *.* to 'mysecretuser'#'%' IDENTIFIED BY 'mysecretpassword' WITH GRANT OPTION;
first check the ip assigned to vmware using from cmd
ipconfig/all
suppose ipassigned to vmware is 192.168.11.1
now in vmware in ubuntu check the ipadress
ifconfig
suppose ip adress of ubuntu is 192.168.11.137
now open mysql configurations
sudo nano /etc/mysql/my.cnf
change the bind address to ubuntu ip address
bind-address = 192.168.11.137
restart mysql
now connect to mysql
mysql -u root -p
and create a user with all privileges and host ip of vmware i.e 192.168.11.1
GRANT ALL ON db.* TO user#'192.168.11.1' IDENTIFIED BY 'PASSWORD';
now try to connect from windows.
also open port of mysql
/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
restart mysql and try to connect on ubuntu host ip address 192.168.11.137
For Heidi SQL I was able to get it to work following the instructions on this article:
http://mysql-tools.com/en/articles/http-tunnel/73-heidisql-a-http-tunnel.html
It uses a program called HTTP Tunnel. It's a lot slower but at least it works. If you use Navicat it comes with a PHP file that you can upload to your server and it will connect via that.
