Database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2) on mac os x 10.9.2

Dear Fellas:
I received "database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2)" on mac os x 10.9.2.
mysql info:
ps -ef | grep mysql

Please help!!

Fascinated and guessing:
Something related to sock(2) because that's not part of your copied info. I'm thinking you've doubled up on sockets and the second socket doesn't exist, meaning you should be connecting to the first socket "mysqld.sock" whether automatic or not.
I've only used GUI tools on purpose, so does this mean you've already got MySQL running and you tried to launch it again manually? Perhaps you already have one instance of a db and you're trying to launch a second instance, and the two can't coexist with a single user local db?
Assuming this is all local, I'd shut down the db service and restart it, out of hand. I've seen similar messages when I set the db to start up on boot, and it didn't finish shutting down when I tried to restart it manually. Usually the GUI won't let me turn it on because it reports it's already running, but in that case it hadn't finished performing what the GUI was reporting.
Just speculating.

ERROR#: 2002 can't connect to MySQL server through socket '/var/mysql/mysql.sock'

I was following this adobe article (
http://www.adobe.com/devnet/dreamweaver/articles/php_macintosh.html)
to set up PHP and MySQL and connect a MySQL database to dreamweaver
in Mac OS 10.4.8 and I kept getting:
"Can't connect to MySQL server through socket
'/var/mysql/mysql.sock' ERROR#: 2002".
After a lot of searching I came across
this
article which said that there was an error in the PHP and MySQL
connection or something.
Anyway all I had to do was type (in a TERMINAL window):
$ sudo mkdir /var/mysql
$ sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
and that fixed the problem, otherwise the adobe article
worked very well.

}the problem occars when there are a lot of queries that the project is sending to the DB (about 10000) the last half queries fails and send an excaption .
after 2 minutes the system seems like working fine.
I am stack with this problem about a year and cann't resolve it.
any idea????
regards
amnon m

well...new it seems to work fine, but is it ok to
keep connection open for good ???
isn't there any other alternative ???I am bit confused are you pooling the connections?
If so, actually the connections will not always stay open.. they will time out after a while when they are not in use but to specifically answer your question.. how could it possible be a bad thing. If the server/your app was getting bogged down with opening and closing connections then pooling solves this..
Finally as to your question of the alternatives... if the problem was opening and closing connections and reusing them through a pool solved this then I think the answer is no. If you don't like a specific part of the way the pool works it is probably configurable in some way and you could always implement your own pool.. although I wouldn't overly recommend that. The bottom line is that you need to keep your connections open for reuse.. pooling is the simplest way to achieve this.. but no there is no alternative to keeping your connections open if you are having the load problems you described.

MySQL conversion: can't connect to mysql server

Hi all,
I've downloaded the latest migration workbench with the mysql plugin. After I've choosen the source database, I don't get a connection to the source database. The hourglass stays visible for about an hour, no message is shown.
The error.log file complains about a NoClassDefFound, but I've installed the latest mysql jdbc driver.
Did I miss something?
Any help appreciated.

Plz help me--error connecting to MySQL server

While trying to connect to the MySQL server database,
SqlConn = DriverManager.getConnection("jdbc:mysql://" + "database_server_addr/database_name?user=kiosk&password=!xyzabc");
I get the following error.
Error while connecting to mysql
Communication link failure: null
Notice the ! symbol(exclamation mark) present in the connection string above for the password value i.e., !xyzabc
Is the problem with the ! symbol in my password, coz I am able to connect
if I changed my password omitting the ! symbol. But I would like to connect with the ! symbol in the password. Any quick help is appreciated.
Thanks,
Bussa.

specify the database Server address, you can't do it with the "HTTP URL"
String url = "jdbc:mysql://xxx.xxx.xxx.xxx";
Class.forName("mySql spec");
Connection con = DriverManager.getConnection(url,"user", "pass");

Problem of remote connection on MySql Server from Mac OSX

Hi everyone,
I have a flash application that work on both plateforms Pc and Mac. In this application i do a connection to a MySqlDatabase to activate it.
so, to make my tests i have a pc and mac on the same home network
to make sure it works fine, i have installed EasyPhp on my PC and MAMP on the Mac, to be able to test the connection to local MySqlServer.
the syntaxe that i use to connect to the database is this one :
mdm.Database.MySQL.connect(host:String, port:String, compression:Boolean, userName:String, password:String, databaseName:String)
So, to connect to local MySqlServer : i have this code:
mdm.Database.MySQL.connect("localhost", "3306", true, "root", "", "DBName");
and it work just fine on the PC using EasyPhp and on the Mac using MAMP. I can connect on my database on each plateform.
So now, i want to connect to our remote MySqlServer, so, to connect to our Private server : i have this code:
mdm.Database.MySQL.connect("64.150.160.230", "3306", true, "userName", "userPassword", "DBName");
on the PC: it works just fine, i am able to connect to our database and do queries on our private server.
on the Mac : it cannot connect... errore message: unable to connect to server
I really don't know where it is coming from.
I would like to test a connexion to my remote MySqlDatabase, by sinf just the terminal. Does anyone know the syntaxe to use to connect to a remote MySqlDatabase using the Terminal?
It can be a blocked port on my Mac, because i am able to connect with this port on my local MySql Server...
Any help will be welcome.
Best regards.

Establishing connection to MySQL server/database

Hi! I've got a question about subj. Here is my code:

Unidentified error when connecting to Mysql server

Hello,
I have two computers. Both computer 1 is configured with dreamweaver cs5 and is successfully connected to the ftp server and its database.
Computer 2 on the other hand with the same version of Dreamweaver and the same settings gives me an unidentified error when I try connecting to the database. I spoke to help chat for my server and confirmed all of the fields are entered in correctly and that I have allowed access to my server from any IP!
I have tried re-installing !
Localhost with Xampp works also!
No success !

Are you using any firewall/antivirus on computer 2?
If so, try to disable and then try,
Also make sure you have the Admin rights on Comp2.
Thanks

Cannot connect to mysql server

Even i already set mysql-connector-java-5.1.3-rc-bin in JDK1.5\lib\ext folder.

Address book application in java using jdbc to connect to mySQL server

hi there .....
as clear from the topic i want to make an address book.....as above
this is my first ever proper application of java
i have this plan
class GUI{* contains all components */}
class links_GUI_to_db{* contains business logic simple enough from name */}
then i make objects of both classes in "Main" class and all processes are done there
as i am totally new to this thing , i would like some advice and an initial guideline on how to proceed
i am NOT ASKING for code but advice on interaction of classes and how to proceed intitially
thanks

Hi,
The answer depends pretty much on how ambitious you are, and several articels and books can be written on the topic, so it's unfortunately not something that can be fully answered in a short post.
My best advice is that you google on MVC and on how to create layered applications. You can after that start reading e.g. JDBC tutorials and Swing tutorials (if that is the UI that you are going to use).

Ps. I would probably not use MySQL as database for an address book. I would instead use a database that doesn't require installation. E.g. H2 or Derby.

Can't connect to local MySQL server through socket '/var/mysql/mysql.sock'

I'm using the pre-installed versions of php and mysql under Mac OS X Server 10.4.4 running on a G4 and am unable to get anything involving mysql to work.
I ssh to the server and enter various commands in Terminal:
on typing "mysql" I get
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2)
and on typing "mysqladmin version" I get
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/mysql/mysql.sock' exists!
On typing "sudo mysqld_safe" I get

I'm trying to get a bug database running (mantis) under Mac OS X Server 10.4.4 that I can access from local clients.
I'm trying to follow directions at http://www.mantisbugtracker.com/manual/manual.installation.php
without knowing anything about mysql or php and I'm stuck on step 3:
"Next we will create the necessary database tables and a basic configuration
file."
I get a message saying
"Does administrative user have access to the database? ( Lost connection to MySQL server during query )"
I don't even know if following the mantis directions has resulted in the creation of a database or not. Where would it be?
Thanks for any help.
Intel iMac Mac OS X (10.4.10)

I've just done a clean install of OSX Server and added the latest MYSQL packaged installer. Afterwards I found the lock file in /private/tmp/mysql.lock
The easiest way to solve this problem is to create a symbolic link so that the lock file appears to be in right place.
e.g.
cd /var
sudo mkdir mysql <== this assumes the directory is missing
cd mysql
sudo ln -s /private/tmp/mysql.sock mysql.sock
After this msql commands should work fine, and you've not fiddled with the security settings on users/groups.

Cannot connect java to mysql server 2000

I was unable to connect to the mysql server 2000 with the jcreator.
The following exception was thrown:
java.net.SocketException
MESSAGE: java.net.ConnectException: Connection refused: connect
STACKTRACE:
java.net.SocketException: java.net.ConnectException: Connection refused: connect at com.mysql.jdbs.StandardSocketFactory.connect<StandardSocketFactory.java:156?
at com.mysql.jdbc.MysqlIO.<init><MysqlIO.java:284>
** END NESTED EXCEPTION **
and the code i used was :
package com.stardeveloper.example;
import java.sql.*;
public class JCustomer {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql:///Customer", "user", " ");
if(!con.isClosed())
System.out.println("Successfully connected to MySQL server...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
I donot have any user and pwd for the MYsql server, it is local host connection and window authentication is used.

eventhough it is local ,you may need to specify dns/localhost/ip with port number.
otherwise you can use myODBC driver which is freely available in mysql website. you can connect to the database using Data source Name, just like using any other ODBC connectivity.

Connecting to SQL Server and MYSQL from a Java stored procedure

hope someone can help with this. i'm trying to connect to different databases (My SQL, SQL Server) from a java stored procedure. when invoking from within an oracle 9i database, i get the java exception error -
"Cannot connect to MySQL server on 135.177.196.75:3306. Is there a MySQL server running on the machine/port you are trying to connect to?java.security.AccessControlException)".
this store procedure works fine when invoked from outside of oracle. any replies would be greatly appreciated. thanks!

the correct drivers have been loaded. it works when called from outside of oracle. only when invoking from within oracle do we get the error message "Cannot connect to MySQL server on 135.177.196.75:3306. Is there a MySQL server running on the machine/port you are trying to connect to?(java.security.AccessControlException)". it sounds like a permissions/security/configuration issue - oracle is not allowing access to the machine/port for the MySQL or SQL Server database. appreciate the responses so far.

Mysql_connect "Lost connection to MySQL..." error 61

A web developer is getting this error on a test web server of ours that is running 10.5.7 Server.
"Warning: mysql_connect() function.mysql-connect: Lost connection to MySQL server at 'reading initial communication packet', system error: 61 in..."
I've seen other postings online for this error suggesting that the line containing 'bind-address 127.0.0.1' be commented out within /etc/my.conf... but this line doesn't exists on my installation.
MySQL and php have been working well for other databases and developers. This is a newly created database.
Has anyone else seen this error and found a fix?
Thanks!

This is more than likely a firewall problem on your users end. I just ran into this when moving my servers to a colocation. Everything was fine until i tried to connect to an outside database from the machines behind the new firewall. was set to allow 3306 in, but not out. And would connect without issues to localhost:/var/mysql/mysql.sock .
from the machine trying to connect from try
shell> telnet <servername> 3306
should be able to login. if refused, then port is closed.
