Connecting to MySQL

By default the mysql client tries to make a connection via a Unix pipe which might not exist.

hendry@manza:~$ mysql --user=root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Solution is to specify the TCP protocol:

hendry@manza:~$ mysql --protocol=TCP
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 82
Server version: 8.0.33 MySQL Community Server - GPL

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
