Check that mysqld is running and that the socket: '/var/lib/mysql. sock' exists!

The/etc/my. cnf file is incorrect. You need to create a new file as follows:
Cd mysql-VERSION to the directory of the decompressed File
Copy
Cp support-files/my-medium.cnf/etc/my. cnf
Reinitialize and create an authorization table
Bin/mysql_install_db -- user = mysql

Start the service
Bin/mysqld_safe -- user = mysql &
