尝试了所有事情仍然得到 ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) in mac

Question

Every time I run XAMPP and try to run $mysql -u root -p , its throwing me an error which is:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

I am using XAMPP version 1.7.3 in Mac OS-10.9. Starting Apache and MySQL is not a problem and I have confirmed Apache has started by going to activity monitor.

Few things I tried:

1. checked if MySQL is running by typing this command in terminal: mysqladmin -u root -p status . Result was:

   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!

2. I checked and found mysql.sock file in /var/mysql/mysql.sock .

Things that could have triggered this error but cant say what is wrong:

1. I recently upgraded my OS to Mavericks from Mountain Lion.
2. I had also installed separate MySQL to work with Ruby on Rails. I have made sure that version is off.

Without fixing this problem I am not able to do any development locally and connecting MySQL in PHP script seems impossible. So any help will be appreciated.

Here is error_log file from /applications/xampp/xamppfiles/logs/error_log :

Answer 1

Finally manage to solve it. First I was looking on wrong directory, I should have looked into /applications/xampp/xamppfiles/ .

List of things I did:

1. there was not tmp folder under /applications/xampp/xamppfiles, so I created it (mkdir tmp).

2. I searched for mysql.sock file and found it under /applications/xampp/xamppfiles/var/mysql/mysql.sock .

As mysql server connection was not working via socket /tmp/mysql.sock , I used following command to point my /applications/xampp/xamppfiles/var/mysql/mysql.sock to /tmp/mysql.sock file.

So this command did the trick:

ln -s /applications/xampp/xamppfiles/var/mysql/mysql.sock /tmp/mysql.sock

3. now I restart xampp services and run: mysql -u root -p , I can get into mysql console. And I also tried connecting mysql from php script and its running ok.

After pulling hair for a day and half I finally managed to get it working hope people will find this helpful.

Answer 2

Not sure how you get a list of running programs on a mac but you should try and verify that mysqld is actually running. (on linux "top -bn1 | grep mysql" would normally show a line of info if it is running, or nothing if it is not.)

You could also try stopping mysqld and see if /tmp/mysql.sock vanishes. If it doesn't then try deleting it and restarting mysql to see if it appears again. (it should)

Do you have any log files that might show what is going on?

Answer 3

Looks like your mysql server is not started. Use the following commands:

mysqld stop
mysql.server start

Answer 4

ln -s /applications/xampp/xamppfiles/var/mysql/mysql.sock /tmp/mysql.sock

在High Sierra上帮了我大忙。

Answer 5

XAMPP mac has the default settings to store mysql.sock another location. Just change it :)

$ vim /applications/xampp/xamppfiles/etc/my.cnf

[client]
#password   = your_password
port        =3306
#socket     =/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
socket      =/tmp/mysql.sock         <---------

...

[mysqld]
user=mysql
port=3306
#socket     =/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
socket      =/tmp/mysql.sock        <---------

Restart mysql, then works.

Answer 6

ln -s /applications/xampp/xamppfiles/var/mysql/mysql.sock /tmp/mysql.sock 

That worked for me. I have MacOs sierra in my Mac and XAMPP 5.6.30-0
