I run the mysql command at the command line but I get this error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I've Googled a lot but I'm unable to resolve the issue.
Please HELP!
It sounds like mysql isn't running. This will tell you if it is or not:
sudo netstat -tap | grep mysql
That's because the path you specified doesnt have the socket required to connnect to the mysql. This problem has happened with me. Either you can reinstall mysql or search for the mysqld.sock and then move it to the specified directory.
Try running this command to start the mysql server
/etc/init.d/mysql start
/etc/init.d/mysql restart

Out of the sudden, I am getting this error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
on mysql when I run mysql -uroot.
I haven't touched web dev for around 1 month and as soon as I wanted to return to my project, I am getting this very annoying error out of nowhere. I have trie all advice and solutions from other answers and none of them work. This includes changing permissions to 777, ownership to root, mysql etc, killing PID all of those and none of them work. I even tried re-installing mysql and still getting the same error. I even re-installed my whole macOS Mojave and still getting the same error. I mean this error doesn't even make sense...
Is mysql completely broken or I am just super dumb?
Has anyone had this issue? If so how did you solve it?
The error says, it's using the socket /tmp/mysql.sock and failed.
Try to troubleshoot with the below things.
check the process status of mysqld and confirm its running or not. If running which socket is using.
ps -ef | grep -i mysqld
Based on the socket file try login to the MySQL through command line.
mysql -uroot -p -S <<file.sock>>
Check the my.cnf to make sure which socket file its mentioned under the [client] group option.
In your case, probably the mysql instance reading the socket from my.cnf files where it placed somewhere. Check the hierarchy of the configuration file usage by mysqld which may be located in either the /etc or /etc/mysql
I tried a lot to install MySQL8 via Homebrew on Mac 10.14.5. I was running MySQL 5.7 before that and did the following: I removed MySQL completely via this tutorial: https://coderwall.com/p/os6woq/uninstall-all-those-broken-versions-of-mysql-and-re-install-it-with-brew-on-mac-mavericks
After that I run mysql and got the message that the command was not known. So I installed mysql with brew install mysql. After installation I did brew link --force mysql and got Warning: Already linked: /usr/local/Cellar/mysql/8.0.19
I edited /usr/local/etc/my.cnf and added default-authentication-plugin=mysql_native_password in the [mysqld] section. After that I restartet the service using brew services restart mysql
brew services list shows me this now:
mysql started root /Library/LaunchDaemons/homebrew.mxcl.mysql.plist
mysql#5.7 stopped
However, when I type mysql in the terminal I get this:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
The /tmp/mysql.sock does not exist.
When I change the host in the my.cnf file from localhost to 127.0.0.1 this error will change into this:
ERROR 2013 (HY000): Lost connection to MySQL server at 'reading initial communication packet', system error: 54
Anyone has an idea what's going on here and how I can fix it? I also googled it and found various Threads, some are saying that the permissions must be changed to this sudo chown -R _mysql:mysql /usr/local/var/mysql but this does not change anything in my case.
After looging in to my ubuntu machine, I try to login to my database using the following command in the shell:
mysql --user=root -p
Then I get the error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2).
What I have tried:
Uninstall and reinstall -> same error afterward.
sudo service mysql start -> Job for mysql.service failed.
Used configuration template in my.cnf (which is /etc/mysql for Linux).
search for mysqld.sock -> The system doesn't find.
Does anybody have another solution that I could try? Thanks!
I was able to connect to SQL by getting another droplet at digital ocean. I install SQL in the new droplet and worked like a charm. I don't understand why the other droplet was giving me that error. Thanks everyone.
I've been trying to work MySQL on Rails 2.3.14. I've to work with Rails2 but i can't work MySQL.
I've setup MySQL with brew according to http://www.frederico-araujo.com/2011/07/30/installing-rails-on-os-x-lion-with-homebrew-rvm-and-mysql/ this tutorial but when i tried to run
$ mysql
i've faced to
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Why?
Thank you.
All right mates.
I got it.
First I killed all mysql process
killall mysqld
and then I uninstalled mysql from brew
$brew uninstall mysql
$brew cleanup
after that I installed mysql again as http://www.frederico-araujo.com/2011/07/30/installing-rails-on-os-x-lion-with-homebrew-rvm-and-mysql/
so I fixed the problem.
MySQL is broken on my Ubuntu OS. It throws the following error:
mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I wasn't able to repair it. So I want to reinstall MySQL. But I didn't find an effective way.
I used sudo apt-get remove mysql-server-5.1,
But after the re-installation, it is still throwing the same error. Any help?
Restart mysqld.
I don't know how I change the passwrod,this may occur when i use some rails app,
in fact i have set a password for mysql,but when i execute rails rake:db:schema:crate, seems it set the password empty
