When I attempt to connect from Windows 7 using 32bit and 64bit mysql-connector-odbc-5.3.2 and the connectionstring:
Provider=MSDASQL;Driver={MySQL ODBC 5.3 Driver};Server=192.168.1.13;Port=3306;Database=mydb;Uid=root;Pwd=****;
I get
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Likewise with version 5.2.6. After downgrading the provider to 5.1 I get:
[MySQL][ODBC 5.1 Driver]Can't connect to MySQL server on '192.168.1.13' (10060)
which is more encouraging as it has at least recognised the provider.
I have tried adding a firewall rule to allow outbound connections to port 3306. I've tried disabling my local firewall. I have checked that the server is listening on port 3306 and verified the IP address. (tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN) I have further verified that I can access the server and that MySQL is running.
When I attempted to connect using the IP address from an ssh terminal to the server itself:
mysql -u root -h 192.168.1.13 -D whiskeywheel -p
I am prompted for the password after which I get:
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.13' (111)
I have added the host/user to the user table in the mysql database and restarted MySQL. I've granted 'ALL' on the database to the user at anyhost ('%') and I've explicitly added access to port 3306 to the ubuntu firewall:
iptables -A INPUT -p tcp --dport 3306 -j ACCEPT
I will of course restrict access prior to deployment but I need to be able to interact with the database in a meaningful form while I'm developing it. I'm happy to re install any of the various components and start again as this is early enough in the project but ideally I'd like to know what I've misconfigured or where I went wrong.
mysql server by default only bind to the loopback address on the sever (127.0.0.1). you have to edit the my.cnf file of the server and do a restart of the mysql server.
also note that specifying localhost is treated special by mysql server. it does not call 127.0.0.1 as one would expects.

I have installed MySQL 8.0.25 on Ubuntu 20.04 LTS (ARM) instance on AWS.
I can access it using 127.0.0.1 address locally, but can't access it remotely from another instance.
"Bind-address" was commented out originally, I uncommented it and changed to "0.0.0.0" (mysql service was restarted) - didn't help, so I commented it back.
"Skip-networking" is not in the cnf file.
I changed the port to 3307 just to be sure that I'm looking at the right cnf, and now MYSQL does listen to port 3307:
locally I can connect using port 3307, but not remotely:
Here are the iptables:
I know that firewall works well, because if I remove port 3307 from the rules, the error is different:
As you can see, TCP error 111 ("Connection Refused") became error 113 ("No Route to Host").
Telnet connection is refused with the same error:
I've rebooted the MySQL instance - no change.
Why would MYSQL refuse remote connection, if "bind-address" is commented out, and firewall is open?
#stdunbar's comment pointed me in the right direction.
The problem happened because I followed the MYSQL installation instructions at https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-20-04 , and ran the security script while configuring MYSQL:
sudo mysql_secure_installation
For some reason, this script causes MYSQL to ignore the bind-address setting in the cnf file, while it still uses the port setting - very confusing!
When I installed MYSQL without running the security script, the "local address" of the MYSQL daemon in the netstat -lnp | grep mysql command changed from 127.0.0.1:
to 0:0:0:0 :
After this, MYSQL started to accept remote connections.
Of course, I still had to create a remote user:
CREATE USER 'root'#'remotehostname' IDENTIFIED WITH caching_sha2_password BY 'newpassword';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'remotehostname' WITH GRANT OPTION;
I'm trying to connect to mysql workbench but I get the following error
Error Message Cannot Connect to Database Server
Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306: Could not open database.
Please: 1. Check that mysql is running on server 127.0.0.1
Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
Check the root has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines).
Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting.
i installed mysql server too in with workbench.help me
I have setup a MySQL 5.6 Server on an Ubuntu 14.04 Server distribution on Virtualbox, and am trying to connect to it via TCP/IP from the host Linux Mint 17 Desktop OS over the WAN.
Connection through the MySQL client on the VM works fine, but whenever a connection is attempted from the host machine (via mysql-client-5.6 package) an error comes back with one of 2 errors:
INPUT: $ mysql -u client -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
or
INPUT: $ mysql -u client -p protocol=tcp -h 127.0.0.1
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)
Server Setup:
Fresh Ubuntu 14.04 Server installation with only mysql-server-5.6 and openssl packages installed from Ubuntu APT repository.
Users created are 'root'#'%' and 'client'#'%', both with full privileges given to them.
Iptables was modified to try and fix the issue (it came completely stripped) and shows: accept tcp connection from mysql and shows:
target: ACCEPT prot: tcp opt: -- source: anywhere destination: anywhere tcp dpt:mysql .
Configuration file "/etc/mysql/my.cnf" was hardly touched, only tried to change bind-address to values 127.0.0.1 , 0.0.0.0 , commented : all unsuccessful. Server and Client socket is set to 3306.
"service mysql status" returns output: "mysql start/running, process 10650"
Checked that tcp port 3306 is being listened to through "netstat -tulpn" command. returns output: PID=tcp6 Local Address=:::3306 Foreign Address=:::* State=LISTEN .
Client Setup:
Installed package mysql-client-5.6 from Ubuntu APT repository
All configurations are preset and untouched.
Would like an affirmation on the following: Was getting the idea that connecting through Unix socket is only possible through the OS hosting the server (internally), while any external OS has to use TCP/IP and so I tried the "protocol=tcp" bit in my 2nd input.
Was searching for a solution for over 2 days now, starting to feel really frustrated. Any useful help would be greatly appreciated!
I am trying to remotely connect to a MySQL server. I have followed advice from (1) and setup a user on the ip address I will be remotely accessing from.
user$ mysql -u TestUser -p -h 129.169.66.149
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '129.169.66.149' (60)
I have checked and the port (default, 3306) is correct and the ip address is correct. MySQL is also running.
From a remote computer, I can successfully ping the server
ping 129.169.66.149
64 bytes from 129.169.66.149: icmp_seq=48 ttl=63 time=1.010 ms
But when I use Telnet:
TELNET 129.169.66.149
Trying 129.169.66.149...
telnet: connect to address 129.169.66.149: Operation timed out
telnet: Unable to connect to remote host
Can anyone advise? Is this a firewall issue?
(1) - https://superuser.com/questions/826896/access-wordpress-mysql-database-remotely
First try to check TCP connection issue, using netcat and telnet : on the mysql server, stop mysqld (to release port 3306) and run netcat on listen mode :
nc -l -p 3306
Now, netcat is listening port 3306 (like mysqld does when it's running) and will show what happen on that port (incoming connections, what's in the wire...).
On your remote computer (mysql client), try to connect to the mysql server host :
telnet 129.169.66.149 3306
or :
nc 129.169.66.149 3306
If this is not working, this is not a mysql server configuration issue but a network issue, and you must check your router firewall rules.
Otherwise, your problem comes from mysql server settings. Check your mysql configuration file for bind-address, and remove them to make mysqld accept clients from any IP address.
The 3306 port on the 129.169.66.149 server is closed you'll have to open this port

I am using Fedora 18 and recently installed MySQL workbench.
I created a new connection in MySQL workbench, but when trying to open I get the following error:
Cannot Connect to Database Server
Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306:
Can't connect to MySQL server on '127.0.0.1' (111)
Please:
Check that mysql is running on server 127.0.0.1
Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
Check the root has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines)
Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting from
Any idea what the issue would be?
Fedora 18 is a Linux Based Operating System and it works on chmod 777. so there should be authentication problem. otherwise server 127.0.0.1 and host name , username same as we keep in windows. you need to set authentication.
