I installed MySQL on Mac OS X Mountain Lion with
homebrew install mysql, but when I tried
mysql -u root I got the following error:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
What does this error mean? How can I fix it?
It’s probably because MySQL is installed but not yet running.
To verify that it’s running, open up Activity Monitor and under “All Processes”, search and verify you see the process “mysqld”.
You can start it by installing “MySQL.prefPane”.
Here is the complete tutorial which helped me: http://obscuredclarity.blogspot.in/2009/08/install-mysql-on-mac-os-x.html
You’ll need to start MySQL before you can use the
mysql command on your terminal. To do this, run
brew services start mysql. By default, brew installs the MySQL database without a root password. To secure it run:
To connect run:
root is the username name here.
This happened after the homebrew install and occurs due to permission issues. The following commands fixed the issue.
sudo chown -R _mysql:mysql /usr/local/var/mysql sudo mysql.server start
brew info mysql
And follow the instructions. From the description in the formula:
Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysql_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html
Hope this helps.
As others have pointed out this is because MySQL is installed but the service isn’t running. There are many ways to start the MySQL service and what worked for me is the below.
To start the service:
- Go to “System Preference”
- At the bottom pane there should be MySql icon.
- Double click that to launch the ‘MySQL Server Status’ and press the button ‘Start MySQL Server’
Mac Yosemite 10.10.3
Installed Package: /Volumes/mysql-advanced-5.6.24-osx10.8-x86_64
Solutions revolve around:
changing MySQL’s permissions
sudo chown -R _mysql:mysql /usr/local/var/mysql
Starting a MySQL process
sudo mysql.server start
Just to add on a lot of great and useful answers that have been provided here and from many different posts, try specifying the host if the above commands did not resolve this issue for you, i.e
mysql -u root -p h127.0.0.1
Warning – this method will remove all of your databases in the
I had MySQL installed with Homebrew, and the only thing that fixed this for me was re-installing MySQL.
On my company laptop, I didn’t have permission to uninstall MySQL from my computer via Homebrew:
$ brew uninstall mysql --ignore-dependencies Uninstalling /usr/local/Cellar/mysql/8.0.12... (255 files, 233.0MB) Error: Permission denied @ dir_s_rmdir - /usr/local/Cellar/mysql/8.0.12
So instead, I removed and reinstalled MySQL manually:
$ sudo rm -rf /usr/local/Cellar/mysql $ brew cleanup $ sudo rm -rf /usr/local/var/mysql $ brew install mysql
And that worked!
Below I’m including the latest instructions from
brew install mysql so newer searches for this issue can benefit:
$ brew install mysql ==> Downloading https://homebrew.bintray.com/bottles/mysql-5.6.26.yosemite.bottle.1.tar.gz ######################################################################## 100.0% ==> Pouring mysql-5.6.26.yosemite.bottle.1.tar.gz To connect: mysql -uroot To have launchd start mysql at login: ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents Then to load mysql now: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist Or, if you don't want/need launchctl, you can just run: mysql.server start
In my case I loaded mysql now via
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist and was then able to launch
$ mysql and be on my way.
I hope this helps recent troubleshooters!
Looks like your mysql server is not started. I usually run the stop command and then start it again:
mysqld stop mysql.server start
Same error, and this works for me.
this problem related to
/usr/local/var/mysql folder access, I remove this folder and reinstall mysql.
uninstall mysql with brew :
brew uninstall mysql
sudo rm -r /usr/local/var/mysql
brew install [email protected]
mysql -u root
This solution works fine for me! BUT YOU LOST ALL YOUR DATABASES! WARNING!
This fixed my issue when I restarted the mysql service. Just run:
brew services start mysql
Ough, that took me a while to figure out. I saw it in a comment. After installing mysql using brew, and starting the service (perhaps using
sudo brew services start mysql) then run:
And MySQL should be running for your thereafter.
For me it was simple as running:
In my case it was simply a matter of deleting a lock file.
sudo rm -f /tmp/mysql.sock.lock
I found the solution to my problem. It was indeed because my MySQL server was not running.
It was caused by MySQL not being correctly set up on my machine, thus not being able to run.
To remedy this, I used a script which installs MySQL on Mac OSX Mountain Lion, which must have installed missing files.
Here is the link: http://code.macminivault.com/
Important Note: This script sets the root password as a randomly generated string, which it saves on the Desktop, so take care not to delete this file and to note the password. It also installs MySQL manager in your system preferences. I’m also not sure if removes any existing databases, so be careful about that.
After working on this for several hours what worked for me was go to /etc/mysql/ and edit the my.cnf file. Add the following
[client] port = 3306 socket = /var/run/mysqld/mysqld.sock
I went through this issue and I managed to run mysql server using below solution
Install mysql through
.dmg(https://dev.mysql.com/downloads/mysql/5.7.html), you will get mysql service panel in system preferences then start mysql from the panel and try
mysql -u root -p
Images attached for reference
I have tried every possible way to solve this issue, like ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock, uninstall and reinstall mysql, make sure mysql is running on xampp but none of it still worked.
Finally, I open up my.cnf (config file) and copy the socket path (make sure to copy the full path else it won’t work). Then I perform this command in my terminal
Lo, and behold, mysql launchs.
This solution will only work if your MySQL is shown running on Xampp/Ampps, but in terminal it is still not connecting to the right socket when you have already attempted something like:
./mysql -u root
brew services start mysql
I hope this helps!
only this has made the trick for me
brew services start --all
(after trying all answers)
I would recommend you to run
before going to
mysql -u root -p
so as to make sure that the mysql server is running before trying to login into it
This happens many times what you start/restart a machine where by no mysql server is running.
I keep coming back to this post, I’ve encountered this error several times. It might have to do with importing all my databases after doing a fresh install.
I’m using homebrew. The only thing that used to fix it for me:
sudo mkdir /var/mysql sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
This morning, the issue returned after my machine decided to shut down overnight. The only thing that fixed it now was to upgrade mysql.
brew upgrade mysql
In my case right after installing the MAMP accessing mysql from the terminal was giving the same socket error. At the end all it wanted was a restart and it’s working.
A lot of other helpful responses here, but nothing fixed this for me. Ultimately nothing I found on this site or others would get any version of MySQL from Homebrew working for me.
It was super painless to just download the DMG from https://dev.mysql.com/downloads/file/?id=479114 (find the appropriate version you need) and let the wizard install it for me. The only other manual step was adding
/usr/local/mysql/bin to my PATH.
I’d recommend this option if brew is giving you trouble.
Update – if this still doesn’t fix it, try completely purging mysql before installing via DMG. Follow these instructions: https://gist.github.com/vitorbritto/0555879fe4414d18569d
rm -rf /usr/local/var/mysql && brew postinstall [email protected] && brew services restart [email protected]
Encountered a similar problem after upgrading to Catalina OS. After running mysqld command, I found that there was some issue with the logs file. It could be different for others.
2019-10-16T04:58:59.174474Z 0 [ERROR] Could not open file '/var/log/mysql/error.log' for error logging: No such file or directory 2019-10-16T04:58:59.174508Z 0 [ERROR] Aborting
Resolved it by creating it and applying proper permissions.
sudo mkdir -p /var/log/mysql sudo touch /var/log/mysql/error.log sudo chown -R _mysql:mysql /var/log/mysql/
brew services restart [email protected]
Issue was resolved.
mysql -uroot -proot
After trying many solutions, seems like the one that finally did the trick was to connect by IP. No longer file sockets getting deleted randomly.
Just update your MySQL client config (e.g.
[client] port = 3306 host=127.0.0.1 protocol=tcp
sudo chown _mysql /usr/local/var/mysql/* helped me finally after trying multitude of options from all these SO answers. The issue with permissions probably arose from improper shutdown of the machine.
just hit “brew services start mysql” in terminal
If you are on OSX and have XAMPP,then please follow these steps:
Thanks to Jackstine’s answer, I was able to do the following:
$ cat ~/.my.cnf
[mysql] # CLIENT # port = 3306 socket = /Applications/XAMPP/xamppfiles/var/mysql/mysql.sock
I hope this helps me again when I forget, in the future!
- Uninstall MySQL.
- Install MySQL.
