[에러] ERROR 2002 (HY000): Can't connect to local MySQL server through socket ''/var/run/mysqld/mysqld.sock' (2) 에러 해결

에러 내용

$ mysql start
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '
'/var/run/mysqld/mysqld.sock' (2)

해결 방법

$ sudo apt install mysql-server
$ sudo mysql

 

참고로

$ service mysql
Usage: /etc/init.d/mysql start|stop|restart|reload|force-reload|status

여기서 시키는 대로 /etc/ 어쩌구로 실행했더니 authentication 문제가 발생해서

그냥 sudo mysql로 실행하는 게 편한 것 같다. 

 

$ sudo mysql
