Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
MysqlSqlMysql Problem Overview
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?

Solution 3 - Mysql
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

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.

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 mysql@5.7
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

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

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.
