I am try to using MySQL Workbench but its showing error "Cannot connect to database".Neither it taking it localhost or my Endpoint of AWS RDS as DNS in host in workbench.
"I am using Xampp for mysql server running on port number 3306 "
Error :
Cannot connect to DataBase Server
Your connection attemp to failed for user 'root' from host to server at localhost:NULL;
can't open named pipe to host:pipe:MySQL (2)
Please:
1.Check that mysql is running on server localhost.
2.Check that mysql is running on port NULL (note 3306 is the default,but this can be changed)
3.Check the root has rights to connect to localhost from your address .
4.Make sure you are both providing a password if nedded and using the correct password for localhost connecting from the host address you are connecting from.
If you want to test the connection to MySql, Use Heidi (i recommend it). If it didn"t work, check if your DataBase server is running in port 3306 by taping:
netstat -atp tcp | grep -i "listen".
You can also change listenning port in /xampp/mysql/bin/my.ini:
my.ini:
Password = your_password
port = 3306 ---> 3307
socket = "/ xampp / mysql / mysql.sock"``
Looks like you have no port configured. Check your connection settings that you have a port set.

I deployed a SQL server on my Mac and configured so that root#% has access to it. I also modified my /etc/hosts to have a mapping between my Mac IP (192.168.1.60) and my MySQL server (192.168.1.60 mysql-server). I also added a binding in my.cnf and then restarted the server:
bind-address = 192.168.1.60
port = 3306
However, when I do (from my Mac): mysql -u root -h mysql-server, I can't connect to the MySQL server (and also when I do a "netcat mysql-server 3306", I have this response: nc: connectx to mysql-server port 3306 (tcp) failed: Connection refused).
Any recommendation ?
Many thanks - C
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 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.
I'm running Linux Mint and trying to connect to mySQL this way
mysql --port=3306 -u root -p
Then it prompts me for my password. This is all fine. Why is it that when I type something like this it still works....
mysql --port=1234 -u root -p
Should that not fail since there is no mySQL server running on port 1234?
The reason I am asking this is because I want to create a SSH tunnel to connect to a database on another server. Let's say the SSH tunnel will forward all my traffic from localhost:3308 to myremoteserver:3306. Since my local mySQL server is accepting my connections on all ports, I cannot actually connect to port 3308 and hit the remote server. I am still hitting my local server....
Even if my SSH tunnel options might have been wrong, I was wondering if anyone knew why I can connect to port 1234 and it still hit my local mySQL server running on 3306?
IIRC mysql connects you to a Unix socket if you are connecting to localhost. Since it does not connect you via TCP in this case, there is no port involved and the port number you give does not matter.
Edit: Not sure if this is true on all systems, but If I use 127.0.0.1 or the hostname instead of localhost, mysql connects via TCP and the port number does matter - I can connect with the correct port number only.
To force a TCP connection use --protocol=TCP.
Example:
First the SSH tunnel
ssh -L 4000:localhost:3306 server.ch
and then connect to the remote mysql server with
mysql -h localhost --port=4000 --protocol=TCP -u root -p
It will ask you for your password before it tries to connect. If you enter your password (or anything else for that matter), and let it proceed, it will respond with something like:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock'
#titanoboa, thx for this! I was having the same issue. Just to add you can actually force TCP connection even for localhost using the following
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
protocol = TCP
Cheers
