B.3.2.2 Can't connect to [local] MySQL server
A MySQL client on Unix can connect to the mysqld server in two different ways: By using a Unix socket file to connect through a file in the file system (default ), or by using TCP/IP, which connects through a port number. A Unix socket file connection is faster than TCP/IP, but can be used only when connecting to a server on the same computer. A Unix socket file is used if you do not specify a host name or if you specify the special host name .
If the MySQL server is running on Windows, you can connect using TCP/IP. If the server is started with the system variable enabled, you can also connect with named pipes if you run the client on the host where the server is running. The name of the named pipe is by default. If you do not give a host name when connecting to mysqld, a MySQL client first tries to connect to the named pipe. If that does not work, it connects to the TCP/IP port. You can force the use of named pipes on Windows by using as the host name.
The error (2002) normally means that there is no MySQL server running on the system or that you are using an incorrect Unix socket file name or TCP/IP port number when trying to connect to the server. You should also check that the TCP/IP port you are using has not been blocked by a firewall or port blocking service.
The error (2003) indicates that the network connection has been refused. You should check that there is a MySQL server running, that it has network connections enabled, and that the network port you specified is the one configured on the server.
Start by checking whether there is a process named mysqld running on your server host. (Use ps xa grep mysqld on Unix or the Task Manager on Windows.) If there is no such process, you should start the server. See Section 2.10.2, “Starting the Server”.
If a mysqld process is running, you can check it by trying the following commands. The port number or Unix socket file name might be different in your setup. represents the IP address of the machine where the server is running.
Note the use of backticks rather than forward quotation marks with the hostname command; these cause the output of hostname (that is, the current host name) to be substituted into the mysqladmin command. If you have no hostname command or are running on Windows, you can manually type the host name of your machine (without backticks) following the option. You can also try to connect with TCP/IP to the local host.
Make sure that the server has not been configured to ignore network connections or (if you are attempting to connect remotely) that it has not been configured to listen only locally on its network interfaces. If the server was started with the system variable enabled, it cannot accept TCP/IP connections at all. If the server was started with the system variable set to , it listens for TCP/IP connections only locally on the loopback interface and does not accept remote connections.
Check to make sure that there is no firewall blocking access to MySQL. Your firewall may be configured on the basis of the application being executed, or the port number used by MySQL for communication (3306 by default). Under Linux or Unix, check your IP tables (or similar) configuration to ensure that the port has not been blocked. Under Windows, applications such as ZoneAlarm or Windows Firewall may need to be configured not to block the MySQL port.
Here are some reasons the error might occur:
mysqld is not running on the local host. Check your operating system's process list to ensure the mysqld process is present.
You're running a MySQL server on Windows with many TCP/IP connections to it. If you're experiencing that quite often your clients get that error, you can find a workaround here: Section B.188.8.131.52, “Connection to MySQL Server Failing on Windows”.
Someone has removed the Unix socket file that mysqld uses ( by default). For example, you might have a cron job that removes old files from the directory. You can always run mysqladmin version to check whether the Unix socket file that mysqladmin is trying to use really exists. The fix in this case is to change the cron job to not remove or to place the socket file somewhere else. See Section B.3.3.6, “How to Protect or Change the MySQL Unix Socket File”.
You have started the mysqld server with the option, but forgotten to tell client programs the new name of the socket file. If you change the socket path name for the server, you must also notify the MySQL clients. You can do this by providing the same option when you run client programs. You also need to ensure that clients have permission to access the file. To find out where the socket file is, you can do:
See Section B.3.3.6, “How to Protect or Change the MySQL Unix Socket File”.
You are using Linux and one server thread has died (dumped core). In this case, you must kill the other mysqld threads (for example, with kill) before you can restart the MySQL server. See Section B.3.3.3, “What to Do If MySQL Keeps Crashing”.
The server or client program might not have the proper access privileges for the directory that holds the Unix socket file or the socket file itself. In this case, you must either change the access privileges for the directory or socket file so that the server and clients can access them, or restart mysqld with a option that specifies a socket file name in a directory where the server can create it and where client programs can access it.
If you get the error message , you can try the following things to find out what the problem is:
Check whether the server is running on that host by executing and pressing the Enter key a couple of times. (3306 is the default MySQL port number. Change the value if your server is listening to a different port.) If there is a MySQL server running and listening to the port, you should get a response that includes the server's version number. If you get an error such as , then there is no server running on the given port.
If the server is running on the local host, try using mysqladmin -h localhost variables to connect using the Unix socket file. Verify the TCP/IP port number that the server is configured to listen to (it is the value of the variable.)
If you are running under Linux and Security-Enhanced Linux (SELinux) is enabled, see Section 6.7, “SELinux”.
B.184.108.40.206 Connection to MySQL Server Failing on Windows
When you're running a MySQL server on Windows with many TCP/IP connections to it, and you're experiencing that quite often your clients get a error, the reason might be that Windows does not allow for enough ephemeral (short-lived) ports to serve those connections.
The purpose of is to keep a connection accepting packets even after the connection has been closed. This is because Internet routing can cause a packet to take a slow route to its destination and it may arrive after both sides have agreed to close. If the port is in use for a new connection, that packet from the old connection could break the protocol or compromise personal information from the original connection. The delay prevents this by ensuring that the port cannot be reused until after some time has been permitted for those delayed packets to arrive.
It is safe to reduce greatly on LAN connections because there is little chance of packets arriving at very long delays, as they could through the Internet with its comparatively large distances and latencies.
Windows permits ephemeral (short-lived) TCP ports to the user. After any port is closed, it remains in a status for 120 seconds. The port is not available again until this time expires. The default range of port numbers depends on the version of Windows, with a more limited number of ports in older versions:
Windows through Server 2003: Ports in range 1025–5000
Windows Vista, Server 2008, and newer: Ports in range 49152–65535
With a small stack of available TCP ports (5000) and a high number of TCP ports being open and closed over a short period of time along with the status you have a good chance for running out of ports. There are two ways to address this problem:
Reduce the number of TCP ports consumed quickly by investigating connection pooling or persistent connections where possible
Tune some settings in the Windows registry (see below)
The following procedure involves modifying the Windows registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore it if a problem occurs. For information about how to back up, restore, and edit the registry, view the following article in the Microsoft Knowledge Base: http://support.microsoft.com/kb/256986/EN-US/.
Start Registry Editor ().
Locate the following key in the registry:
On the menu, click , and then add the following registry value:
This sets the number of ephemeral ports available to any user. The valid range is between 5000 and 65534 (decimal). The default value is 0x1388 (5000 decimal).
On the menu, click , and then add the following registry value:
This sets the number of seconds to hold a TCP port connection in state before closing. The valid range is between 30 and 300 decimal, although you may wish to check with Microsoft for the latest permitted values. The default value is 0x78 (120 decimal).
Quit Registry Editor.
Reboot the machine.
Note: Undoing the above should be as simple as deleting the registry entries you've created.
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost’ (10061)
I have installed MySQL version 5.6 on windows 7. My Installation was successful and without any error. I received “ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost’ (10061)” while I was trying to start MySQL server from command prompt. I am attaching the screenshot of the error I received.
|Starting MySQL From Command Prompt|
When I could not connect to MySQL server installed on my windows. I tried to connect MySQL Server directly by using “MySQL5.6 Command Line Client”. Same error was occurring and MySQL Command line was disappearing.
I was little worried of this error – ERROR 2003 (HY000). I did not get any of issues while installing MySQL5.6 on windows so MySQL server should work properly.
I did search on internet (MySQL forum, DB related forums) and I resolved Can’t connect to MySQL server on ‘localhost’ (10061) error. Now I was able to run MySQL server from command prompt.
Reason for ERROR 2003 (HY000): Can’t connect to MySQL server on ‘localhost’ (10061) – MySQL services has not been started.
