Re: Protocol mismatch; server version = 11, client version = 10

1. Usually it means you are on X protocol,
https://dev.mysql.com/doc/mysql-port-reference/en/mysql-ports-reference-tables.html

2. use [netstat -an|grep 3306] to check if 3306 port is opened.
you should get something likes below

tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
tcp6 0 0 :::33060 :::* LISTEN

if you have 127.0.0.1 in front of 3306, then you need to disable the binding.

in mysql 8, it is
[sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf]

use # to disable the line of bind-address = 127.0.0.1, then save,
restart mysql and check port again.
