MySQL problem -- ERROR 2002 Can't connect to local MySQL server

Not Sure if this would be a right forum for my problem...
I'm installing mySQL on my iBook, and thought that I have configured it. But then, after followring some instuctions from Adobe and Marc Liyanage sites, I have a problem to connect. This is what I've done in "TERMINAL"
~username$> cd /usr/local/mysql
mysql ~username$> sudo chown -R mysql data/

Your biggest 'issue' right now is that your mysqld process is stopping on you -- making a connection impossible.
Why it's bombing might be in a log .. try in mysql/data/usr.local.err .. and fix why itsbombing.
To connect to it it'll be : mysql -u root -ppassword -D database

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:

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.

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

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.

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.

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

Data Services=3.1
Repository=12.2.2.0000
Red Hat Enterprise 5
Designer,Job Server,Job Engine=12.2.2.3
After an unscheduled server reboot with DS up and running when trying to start a job in either Data Services Management Console or DS Designer getting the following:
"Can't connect to local MySQL server through socket '/tmp/mysql.sock'"
The mysql.sock have never been in /tmp and on the production server it does not exist there and the production server is up and running correctly. If a link is created to mysql.sock(/home/user/boedge31/bobje/mysql) the job will start but return this message:
"Cannot retrieve <Version> from the repository. Additional database information: <SQL submitted to ODBC data source <localrepo> resulted in error <MySQL ODBC 3.51 Driver mysqld-5.0.46-enterprise No database selected>. The SQL submitted is <select VERSION, SECURITYKEY, GUID from AL_VERSION where NAME = 'Repository Version'"
I checked and AL_VERSION and the Version field exist.
Before the shut down DS was working correctly and had no issues. My best guess is a part of the repository was corrupted during the unscheduled shut down. It seems like DS has "forgotten" some of the settings.
Any suggestions on a possible solution?

The issue has been solved.
There was a bad path in $LD_LIBRARY_PATH.
Removed the path and DS started working again.

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:

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.

Can't connect to local web server

I'm not quite sure when this happened; I think it was upgrading to iPhoneOS 3.x but I can't swear to that (currently running 3.1). Anyway, the problem is that, whether from my app or even simply using Safari, I can't connect to a local webserver. If I'm on one computer in my office (working over WiFi just like my iPhone), and type "http://192.168.1.110/file", where 110 is a different computer, Safari will display the page just fine. But if I'm using my iPhone in the office, on the same network, and type the same URL, it will not connect. For SURE this used to work, and I haven't changed any settings on my network or on my iPhone for that matter.
No problem with connecting to external websites, clearly.

Web services are not relevant to DNS host names. You'll need to configure a default domain name for whatever is being used as the local domain, whether that is established via System Preferences or via DHCP settings. If your Windows box is running a DNS server, you'll need to set the Mac DNS resolver address at the Windows DNS server.

MySQL Error 2002 when attempting to make a MySQL Connection

I'm trying to make a MySQL Connection and I've got my Staging/Testing Server setup as FTP with the proper host, username and password for FTP, root directory set to '/' (without the quotation marks) and Web URL set to http://www.mysite.com/
Tested the FTP and it connects.
For mySQL connection in my bindings, I'm using:
Connection Name; connRecords
MySQL Server: localhost
Username and then my Password for my DB which obviously I won't list here.
I click Select Database and that's when I get the prompt:
MySQL Error: #2002
Can't connect to local MySQL Server through socket '/tmp/mysql.sock' (2)
What does that mean and how do I get this to work?

On a Mac, connection to MySQL is done through a socket (mysql.sock). The fact that there's a (2) after mysql.sock indicates there's something wrong with the socket. Usually, you can clear the problem by powering down your computer and then restarting. Don't just do a restart. Make sure the computer switches off completely to clear the socket.

Can't connect to X11 Windows Server - Error

Error -2147467259, can't add item to OPC Server

I am using a DataSocket connection to read/write through an OPC Server (GE SRTP) to PLC software (PME). Everything works fine on my 2 different development PC's in my office, both in .vi form, and executable. I have distributed my executable on our network, and 2 of the 4 PC's we use to test product work fine. The other 2 PC's have the same problem, error -2147467259, can't add item to OPC server. When the OPC Server is called by LabVIEW, it launches successfully, but immediatly shows the 'can't add item to OPC Server'. I believe that it has to do with the registry. I registered the opcproxy.dll, and it still fails. LabVIEW 7.1, Windows XP machines.
Thanks, Alan

Duplicate post, please refer to:

For original thread.
I would like to echo Sam's inquiry about launching the OPC server outside of LabVIEW and verifying that it can be connected to. Also, under what user name is the OPC server being launched? Sometimes you can run into trouble if the user name is not the current user logged onto the system, but I haven't heard of it causing this error. You can see what user launched the service under Control Panel >> Administrative Tools >> Services. You can verify the default user running the application by going to Control Panel >> Administrative Tools >> Component Services and navigating to Component Services >> Computers >> My Computer >> DCOM Config Right click on your DCOM server and select Properties. Then go to the Identity tab and make sure The Interactive User is selected.

"oemcrtl start oms" doesn't work, the error is "can't connect to OMS"

I created the repository by emca successfully, "lsnrctl start" is no problem, but when I run "oemctrl start oms", I got error message "can't connect to OMS", I should check which configure files?

Hi,
May be this is unnecessary to say. Behalve your listener also the database where your management server repository resides has to be open. Then start the management server with the following command:
"oemctrl start oms sysman/oem_temp@<name of your machine>" (so replace name of your machine). Should be working if you can open your database.

Mysql socket error 2002

I've read all about this error and have played around with it for a while and still can't get it to work. This is how I got to where I am.
1. installed OS X Server fresh and updated to 10.4.7
2. installed entrophy php 5.1.4 from the installer pkg
3. installed mysql standard 5.0.22 from the installer pkg
4. installed phpMyAdmin and am trying to browse to http://localhost/phpMyAdmin/index.php and am getting the socket error 2002
I read the technote http://docs.info.apple.com/article.html?artnum=302977 which refers to the mysql.sock file.
when I start up mysql, it says 'running' and the mysql.sock file is in /var/mysql/ my php.ini file is pointing there. the /etc/my.conf file is pointing there.
yet I'm still getting this error.
What am I missing?

At this point, you have two versions of PHP and two versions of MySQL installed on your system. So, when you say you start up MySQL, how are you doing that?
For a MySQL-package installed version, you need to start up MySQL in the path /usr/local/mysql/bin/... or use the StartupItem they provide, which would be "/Library/StartupItems/MySQLCOM/MySQLCOM start". Then check where the mysql.sock file is with "/usr/local/mysql/bin/mysqladmin -u root variables" (or "/usr/local/mysql/bin/mysqladmin -u root -p variables", if you've given your root user a password so far).
Also, you can check your PHP installation's default MySQL socket file search path with "/usr/local/php5/bin/php -i" and see what the "MYSQL_SOCKET" variable states is the location for the MySQL socket file.
You just have to make sure these two things are in sync in order to get something like phpMyAdmin to run.
NOTE: If you just type "php" or "mysql" at the command line, you're going to be launching/using Apple's preinstalled versions, so you'll always need to use the full path when working on the command line.
