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've imported my databases on the server and I want to access them locally. The problem is I cannot. I mean the server doesn't response to my request.
I've added root to having access to "mydb" user list and I've given (granted) all privileges to it. Also I've commented bind_address in my.conf file and then I've restarted the mysql.
Still when I run this command:
telnet <ip> 3306
No response received.
Any idea how can I make a connection between my local and the database on the server?
MyTests:
sudo netstat -plnt
tcpdump port 3306
sudo netstat -tulnp | grep 3306
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 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?

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

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.
