ok here's the thing I tried installing MySQL-server and it did install perfectly no problem there.
later I had had to format my system and then when I tried to install it, it did install but it did not prompt for the root password. when I later tried to reset the root password here's the problem I get
user#user:~$ sudo /etc/init.d/mysql stop
[ ok ] Stopping mysql (via systemctl): mysql.service.
user#user:~$ sudo mysqld --skip-grant-tables &
[3] 13831
user#user:~$ mysql -u root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
[3] Exit 1 sudo mysqld --skip-grant-tables
I tried resolving the 2002 error but I am unable to do so. any help will be appreciated.
from what I understand I should not get the 2002 error to proceed further
The error is probably due to error in installation. Try the following:
Ensure that my MySQL service is running by executing the following command in the terminal:
$ sudo service mysql start
Verify the state of the process:
$ ps -A|grep mysql
$ ps -A|grep mysqld
Then kill the process with the following command:
$ sudo pkill mysql
$ sudo pkill mysqld
Finally restart the service:
$ sudo service mysql restart
And run the following command:
$ mysql -u root -p
Step#1: Run this command:
sudo mysql_secure_installation
Step#2: press n
Step#3: input your password.
Step#4: press y for until it says All done!
or follow this video tutorial
Also to change the password use this command:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password';
I have a Ubuntu 14.04. server with LAMP installed where an Owncloud is running. I tried to install paperwork which didn't work out but thats not the problem.
After restarting my server I tried to access my owncloud again but I am facing an internal server error. See following picture.
Owncloud error
I looked in the log /var/log/apache2/error.log and theres following phrase:
Lost connection to MySQL server during query' in ...
I tried to restart the mysql service but this error appears:
stop: Unknown instance:
start: Job failed to start
Then I tried to login to mysql with mysql -u root -p and follorwing error appears:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I've looked for the sockets on the machine with find / -type s and the socket was there: /run/mysqld/ .
I created a symbolic link and pasted it to /var/run/mysqld/mysqld.sock
Unfortnutely nothing worked. After restarting again I can't find the socket anymore the output of find / -type s is:

Update
I've reinstalled the server so problem is over :D
If you install lampp server, run mysql first
sudo /opt/lampp/lampp startmysql
Then make "mysqld" directory in /var/run
cd /var/run
sudo mkdir mysqld
Link your mysql from lampp to /var/run/mysqld
sudo ln -s /opt/lampp/var/mysql/mysql.sock /var/run/mysqld/mysqld.sock
run mysql -u root -p . hope may help you
If you install LAMPP server, run MySQL first
sudo /opt/lampp/lampp startmysql
Then make "mysqld" directory in /var/run
cd /var/run
sudo mkdir mysqld
Link your mysql from lampp to /var/run/mysqld
sudo ln -s /opt/lampp/var/mysql/mysql.sock /var/run/mysqld/mysqld.sock
run MySQL
mysql -u root -p .
If MySQL fails with «mysql» not found, install:
sudo apt install mysql-client-core-5.7
sudo apt install mariadb-client-core-10.1
There is any issues with the mysql services. Please try to restart mysql services and check the mysql error logs for more information
I opened my application (in Rails) on Amazon EC2 and got an error - thus I checked the logs and there is following:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
10 hours ago was everything working yet. What's the problem? A lot of traffic?
The app is running on Micro Instance.
How to fix this issue and how to avoid it in the future?
Thank you very much

In my case, the server had apparently restarted at some point, and mysql was not started when it did. I simply typed the command to start and it worked:
sudo service mysqld start
locate your locate my.cnf file see there for line as socket = ../../mysql.sock
you need to replace the path with your path as
socket = /run/mysqld/mysqld.sock
if the path matches let me know
Cross posting my response from here.
I had this same problem on an ec2 instance. These instructions worked perfectly for me:
Redhat Enterprise Linux - RHEL 5 / 6 MySQL installation
Type the following command as root user:
yum install mysql-server mysql
Redhat Enterprise Linux - RHEL 4/3 MySQL installation
Type the following command as root user:
up2date mysql-server mysql
Start MySQL Service
To start the mysql server type the following command:
chkconfig mysqld on
/etc/init.d/mysqld start
Setup the mysql root password
Type the following command to setup a password for root user:
mysqladmin -u root password NEWPASSWORD
Test the mysql connectivity
Type the following command to connect to MySQL server:
$ mysql -u root -p
In my case I used command below:
project_folder > mysql.server start
After system return SUCCESS message it worked OK.
mysql-server is not installed by default on the Amazon Linux AMI. Use these commands to install it:
$ sudo yum install mysql-server
$ sudo chkconfig mysqld on
$ sudo /etc/init.d/mysqld start
$ mysqladmin -u root password NEWPASSWORD
$ mysql -u root -p
To solve this error first find your socket file, run the following commands in terminal
mysqladmin variables | grep socket
For me, this gives:
| socket | /var/run/mysqld/mysqld.sock
Then, add a line to your Rails application: config/database.yml:
development:
adapter: mysql2
host: localhost
username: root
password: xxxx
database: xxxx
socket: /var/run/mysqld/mysqld.sock
This will solve this problem.

Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (38)

Closed 21 days ago.
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?
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: mysql_secure_installation.
To connect run: mysql -uroot. 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
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".
The above quote is from the blog Obscured Clarity, "Install MySQL on Mac OS X", where you can also find the complete tutorial that I found most helpful.
Run: 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
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'
My env:
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
The designated data directory /usr/local/var/mysql/ is unusable. You can remove all files that the server added to it.
MacOS:
$brew services stop mysql
$brew services list
$brew uninstall mysql
$brew install mysql
$brew postinstall mysql
If Any error found then run those cmd
! Warning: this will delete any databases on this server:
$sudo rm -rf /usr/local/var/mysql
$sudo rm /usr/local/etc/my.cnf
$brew postinstall mysql
$brew services start mysql
$mysql_secure_installation
Completed All process of secure installation then run
$mysql -u root -p
Congratulations you’ve just set up mysql!
Warning - this method will remove all of your databases in the /usr/local/var/mysql folder
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!
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.
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.
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 mysql#8.0
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
In my case it was simply a matter of deleting a lock file.
sudo rm -f /tmp/mysql.sock.lock
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:
$ mysqld
And MySQL should be running for your thereafter.
For me it was simple as running:
/usr/local/opt/mysql/bin/mysqld_safe
instead of mysqld
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
just hit "brew services start mysql" in terminal
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
AFTER USING ALL THE ABOVE SOLUTIONS, NOTHING WORKED FOR ME BUT THIS WORKED.
I you have installed MySQL using HomeBrew then check System Preferences > MySQL in your mac that MySQL Server is stopped if it is running stop it by clicking on Stop MySQL Server and start MySQL from terminal writing the command mysqlserver.start.
If it doesn't work you can also try:-
If you have also installed MySQL workbench then just uninstall MySQL workbench and MySQL and after that install MySQL first and then MySQL workbench.
I would recommend you to run
mysql.server start
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
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. /usr/local/etc/my.cnf) with:
[client]
port = 3306
host=127.0.0.1
protocol=tcp
Probably you might have faced some issues during the homebrew mysql installation and mysql services might not be running. If that is the case, then it might be worth trying below steps to reinstall mysql properly and then try to connect.
sudo chown -R $(whoami) /usr/local/var
sudo chown -R $(whoami) /Library/Caches/Homebrew
brew uninstall mysql
brew install mysql
mysql.server start
mysql -uroot
Homebrew will absolutely never repair the permissions using a standard reinstall, and chasing down which folder/file is corrupted will take longer than it is worth.
In this case - blow away the mysql install manually and reinstall via homebrew. Takes about 2 minutes.
cd /usr/local/var
sudo rm -rf mysql
brew install mysql
Homebrew installs mysql insecure by default, so if you want a password:
mysql_secure_installation
Then fire it up.
mysql -uroot
After installing MySQL on my mac m1 macOS Monterey, using brew install mysql I got this info:
[System] [MY-013169] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld (mysqld 8.0.27) initializing of server in progress as process 3624

[System] [MY-010910] [Server] /opt/homebrew/Cellar/mysql/8.0.27_1/bin/mysqld: Shutdown complete (mysqld 8.0.27) Homebrew.
and this warning:
Warning: The post-install step did not complete successfully You can
try again using: brew postinstall mysql
After that I try to start MySQL using brew services start mysql, and I got this error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/tmp/mysql.sock' (2)
I managed to fix it using:
> rm -rf ~/opt/homebrew/var/mysql/
> brew postinstall mysql
Now you can connect with mysql -uroot or mysql -uroot -p.
only this has made the trick for me
brew services start --all
(after trying all answers)
I managed to solve this issue by changing localhost to 127.0.0.1
For my case, just specify host as 127.0.0.1, instead of localhost:
$ bin/mysql -uroot -p -h127.0.0.1
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

if you are using Kali linux you might want to specify the host explicitly
do that with
mysql -h 127.0.0.1 -u root
where 127.0.0.1 is your localhost
