I have installed MySQL server and trying to connect to it, but getting the error:
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) I have checked my /tmp directory and there is no mysql.sock. I can't find mysql.sock anywhere. I read that it might be in
/var/lib/mysql/mysql.sock But I checked there as well and there is even no mysql directory, only some postfix thing inside /lib. Could anyone help me with this problem?
Try to start the MySQL server:
mysql.server start
mysql.server startI got the same question after updating OS X Yosemite, well the solution is quite simple, check system preference -> mysql, the status was STOP. Just restart it and it works fine on my mac now.
For MAMP
ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock UPDATE: Every time my computer restarts I have to enter this command, so I created a shortcut.
Do the following in terminal type:
~: vi ~/.profile Add
alias ...='source ~/.profile' alias sockit='sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock' Save.
In terminal type:
~: ... to source the .profile config.
Now in terminal you can just type
~: sockit 
Following command resolved my issue:
sudo chown -R _mysql:mysql /usr/local/var/mysql sudo mysql.server start 
brew install mysql but nothing of the commands homebrew told me to run worked properly. This made every problem go away... Thank you!! What exactly is that first line that you wrote? What does it mean?
sudo brew services start mariadbalso works to start mariadb at boot (not just at login). YAY! Thank you!After trying all solutions it worked only for me after specifying the host
mysql -u root -p -h127.0.0.1 when asking for password
Enter password: press enter
and it will work , if everything is ok as above .
-h 127.0.0.1, it always prompt Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2); after adding the argument, it works well.
mysql -u root -h127.0.0.1 without the -p flag worked for me, since when i installed MySQL I never ran the mysql_secure_installation command. My understanding is that in this case the installation defaults to no required password.After struggling for hours the only thing which worked was
sudo mysql.server start Then do a secure installation with
mysql_secure_installation Then connect to the db via
mysql -uroot -p Mysql is installed via homebrew and the version is
Server version: 5.7.21 Homebrew Specifying the version might be helpful as the solution may be different based upon the version.
Try this it worked for me.
sudo /usr/local/mysql/support-files/mysql.server start 
In your mysql config file, which is present in /etc/my.cnf make the below changes and then restart mysqld dameon process
[client] socket=/var/lib/mysql/mysql.sock As well check this related thread
Can't connect to local MySQL server through socket '/tmp/mysql.sock
/etc/mysql/my.cnf
/tmp/mysql.sock as the sock locationFollowing resolved my issue:
Check where is your MySQL server is listning to: netstat -nlp If it is listning to TCP then use 127.0.0.1 while connecting to DB instead of "localhost"
Check MySQL doc here
First Type this-:
brew services start mysql Then this -:
mysql -uroot Type in the terminal as follows:
mysql.server start If you are using XAMPP in Mac OS X and have installed MySQL with Homebrew you may have this problem. In XAMPP manager window go to Manage Servers and select MySQL, then click configure and open the configuration file, there you have the socket file path, put the path in your MySQL host config and it should work.
It's something like this:
... [client] #password = your_password port = 3306 socket = /Applications/XAMPP/xamppfiles/var/mysql/mysql.sock ... then, for instance in Django:
... DATABASES = { "default": { "ENGINE": "django.db.backends.mysql", "NAME": "database_name", "USER": "user", "PASSWORD": "password", "HOST": "/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock", "PORT": "", } } ... Hope this helps.
First, knowing where the data directory was for me was the key. /usr/local/var/mysql In here, there was at least one file with extension .err preceded with my local machine name. It had all info i needed to diagnose.
I think i screwed up by installing mysql 8 first. My app isn't compatible with it so i had to downgrade back to 5.7
My solution that worked for me was going to /usr/local/etc/my.cnf
Find this line if its there. I think its mysql 8 related:
mysqlx-bind-address = 127.0.0.1 Remove it because in the mysql 5.7 says it doesnt like it in the error log
Also add this line in there if its not there under the bind-address.
socket=/tmp/mysql.sock Go to the /tmp directory and delete any mysql.sock files in there. On server start, it will recreate the sock files
Trash out the data directory with mySQL in the stopped state. Mine was /usr/local/var/mysql . This is the same place where the logs are at
From there i ran
>mysqld --initialize Then everything started working...this command will give you a random password at the end. Save that password for the next step
Running this to assign my own password.
>mysql_secure_installation Both
>brew services stop [email protected] and
>mysql.server start are now working. Hope this helps. It's about 3 hours of trial and error.
Stoping and starting the mysql server from terminal resolved my issue. Below are the cmds to stop and start the mysql server in MacOs.
sudo /usr/local/mysql/support-files/mysql.server stop sudo /usr/local/mysql/support-files/mysql.server start Note: Restarting the services from Mac System preference didn't resolve the issue in my mac. So try to restart from terminal.
Faced the same issue while taking mysql dump: Can't connect to local MySQL server through socket '/tmp/mysql.sock
Try to give the path for mysql.sock explicitly.
type ps -ef|grep -mysql
Get the path for mysql.sock from this command, e.g /var/lib/mysql/mysql.sock
mysqldump --socket=/var/lib/mysql/mysql.dump -u username -pPassword
you can try this with any mysql command
For CentOS, the file to init mysql is located here:
/etc/init.d/mysqld start I have spent lots of time doing this I want to put my django app on my server and when I run python manage.py migrate I met this questions
And!! I set this ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock It worked finally!
I have faced the same issue. Here is how I have fixed it.
Step 1: Remove mysql using command:
brew uninstall --force mysql Step 2: Run command brew doctor which will give you some hint related to your brew packages.
Step 3: Cleanup brew packages using command:
brew cleanup Step 4: Move/delete previously installed mysql data using command:
mv /usr/local/var/mysql/ /usr/local/var/old_mysql Step 5: Finally install mysql again using command:
brew install mysql I start mysql from settings,it works!
Try to restart MySql server using
brew services stop [email protected]
if even after this issue is not resolved then try following command
brew postinstall [email protected]
if you gets following error -
2023-06-18T09:23:53.239569Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2023-06-18T09:23:53.241698Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting. 2023-06-18T09:23:53.241717Z 0 [ERROR] Aborting then please delete mySql directory. Search location of your file on Google. In my case it was /usr/var/mysql
I was getting the same error. I overlooked some Caveats when reinstalling mysql via homebrew as listed:
==> Caveats Upgrading from MySQL <8.4 to MySQL >9.0 requires running MySQL 8.4 first: - brew services stop mysql - brew install [email protected] - brew services start [email protected] - brew services stop [email protected] - brew services start mysql I followed those steps and got it working again :)
If you're running on a macOS it's just easier to first check go to 'System Preferences' and see if MySQL is running or not.
