Can't connect to local MySQL server

I want to run a website from my computer. I use XAMPP on a Kali Linux. I installed MySQL server with the command: apt-get install mysql-server After it was successfully installed, I entered the command mysql_secure_installation It prompted me to login to MySQL, but it repeatedly gave the error ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) I tried my password several times, with no changes just to check if I have typed it wrong the first time. Can anyone tell me how to fix this? I am following a tutorial from this site .
