I've run into a problem here, and I'm not sure what to do. I migrated a Yosemite Mac to a new Mac Pro. Apache turns on, but MySql does not with this error: The operation couldn’t be completed. (XAMPPErrorDomain error 1.)
I didn't know if I need to reinstall MySql or upgrade it, or what this error means. I created the plist file as in the example and ran permissions, but that did not change the outcome. Going to websites in localhost, WordPress shows an error establishing db connection.
I went to Github to install MySql and it went fine, but it does not work with Xampp and Desktop Server. I chose to NOT start MySql when I rebooted, but apparently the Github version started anyway (and I cannot find a way to turn it off!) Now when I try to start MySql from Xampp, it says another version is already running.
Any help appreciated.
When I ask for version number in terminal I get this response:
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
HOWEVER, when I went to /var/ and temp I found an alias for mysql.sock, BUT it was not connected to an original file... Now that file does not exist anywhere on my computer.
Open /Applications/XAMPP/xamppfiles/xampp and add this line somewhere at the top:
unset DYLD_LIBRARY_PATH
I found that what was required was a complete uninstall of MySql following this procedure: http://bytearrays.com/completely-uninstall-mysql-mac-osx/
And then a reinstall. ServerPress.com was very helpful in diagnosing the problems.

I recently upgraded my Mac Pro to a Mac Mini and used the migration assistant to transfer all my files and applications across to the Mac Mini.
I also re-installed macports and configured apache etc. So I've managed to get my localhost and php working on the new machine.
However I am now unable to start mysql from terminal?
When I try my usual:
mysql5 -u root -p;
and got the following error:
Error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)
I've also tried restarting mysql:
sudo opt/local/share/mysql5/mysql/mysql.server restart
and got the following error:
ERROR! Manager of pid-file quit without updating file.
When I navigate to my mysql5 directory /opt/local/var/db/mysql5/ I see a list of my databases, and see the following PID files:
myName.local.pid
and
localhost pid
So the structure is similar to what was on my old Mac but I confused as to what is causing mysql to not start?
Interestingly, mysql must be still working because when I run an .php scripts in my browser the mysql queries work and the data is being retrieved.
Any help much appreciated.
SOLVED
I would like to share the solution that I came across to resolve this issue.
When you update to El Capitan from a previous version of OSX your mysql settings get lost. When you try to connect via:
mysql5 -u root -p;
I was getting the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)
The problem was with my.cnf!
The default configuration of macports mysql does not come with a my.cnf (it does however have others my-medium.cnf, my-small.cnf) so the Macports mysql client is going to look where the Macports server is set to look.
I also learned that if you've changed the socket path away from the default then you need to tell everything where it is. Most programs have a hard coded default that can be overridden, I had overridden the macports default to the one php is compiled to, so you need to tell the client what you've changed it to otherwise how is it supposed to know.
Because I did not have a copy of my.cnf in opt/local/share/mysql5/mysql, the client did not know where to look for the socket. So I had to define the path to the socket in the my.cnf for both the [client] and [mysqld] configurations.
The in my case the path to the socket should have been:
socket = /opt/local/var/run/mysql5/mysqld.sock
I then restarted mysql:
sudo /opt/local/share/mysql5/mysql/mysql.server restart
And SUCCESS at last.
Hope this helps.
I downloaded Mac OSX MySQL Community edition (http://dev.mysql.com/downloads/mysql/), and when I start it at
/usr/local/mysql/bin/mysql
I meet with the following issue:
ERROR 2002 (HY000):
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Anyone have any good ideas? Thanks in advance.
Meeting with new issues cannot connect to local MySQL instance using MySQL WorkBench, here are my setup and error, looks access denied and anyone have any ideas?
Most likely the service isn't running or it's looking for the socket in the wrong path.
The /usr/local/mysql/bin/mysql call you made is actually the client, not the server/service.
There should be a mysql_safe executable in that same directory -- try calling that first (you may have to be root).
sudo /usr/local/mysql/bin/mysqld_safe
I have my websites on a VPS - CentOS. Suddenly all of them stopped working and are showing database connection error.
I have tried restarting mysql with the following command in SSH /etc/rc.d/init.d/mysqld restart but when it tries to stop it it says "Failed".
Any idea on what could I do?
Please check you mysql log file (/var/log/mysqld.log).
I just installed mySQL and when I try to type mysql in my mac terminal I'm getting
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
I tried searching for an answer but I'm still stuck. Also, I don't know if this is relevant or connected, but when I go to my preference panel to try to start mySQL it doesn't start. On some sites such as other stackoverflow pages, it says to try running "/usr/local/mysql/bin/mysqld_safe" but for me it just permission denied..
I tried to do ps -u mysql to check if it's running and it printed out and an address: usr/local/mysql/bin/mysqld --basedir=/usr/local. So I assume it's running? Even though I can't physically press the button and enable it in the preference panel which is weird.
EDIT: I typed
$ sudo /usr/local/mysql/bin/mysqld_safe
Password:
130930 11:55:15 mysqld_safe Logging to '/usr/local/mysql/data/myname-mac.att.net.err'.
130930 11:55:15 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
130930 11:55:18 mysqld_safe mysqld from pid file /usr/local/mysql/data/myname-mac.att.net.pid ended
why did it end right there?
I had this same error message for days and finally figured it out.
I had somehow gotten a my.cnf file on my computer from AMPS or possibly another MYSQL install (that I believed I had deleted).
But it turns out it was a hidden file in /etc/ that I had to manually delete. http://ianlunn.co.uk/articles/quickly-showhide-hidden-files-mac-os-x-mavericks/
Finally, I installed MySQL with homebrew one more time –– and success! It works. Also of course this time I spot a message in the homebrew setup process that points out the problem I was having:
A "/etc/my.cnf" from another install may interfere with a
Homebrew-built server starting up correctly.
Hope this helps.
I also experienced a similar error. After trying all prescribed solutions like in this related post, noticed that it was a simple solution: first make sure the mysql daemon is running. For example, on a Homebrew installation (macOS), start mysql with: brew services start mysql
I recently upgraded to a new macbook pro and haven't been able to get mysql to install. I have been trying to install using the:
mysql-5.5.8-osx10.6-x86_64.dmg
which 'should' work for my machine, but is not. After installing the three pieces (mysql.pkg,
startup.pkg, prefpane) I get nothing. Trying to start mySQL through the prefpane freezes sysprefs. Trying to start via the terminal gets this error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
So I deleted all of the mysql install files and reinstalled following these instructions:
https://discussions.apple.com/message/12820394
when I get to the step where I would set up the root password i get the following error:
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
This is perhaps due to the fact that there are no mysql related files in /tmp ? I can't find anything *.sock anywhere on my machine at all. I really don't know much about server admin, so I could be totally confused and off here.
It can have moved to /var/mysql/mysql.sock. I think it is the new position. You may need to point your php.ini to that or create a symbolic link to ln -s /var/mysql/mysql.sock /tmp/mysql.sock...
