MySQL - change the default of default_authentication_plugin

since Mysql version 8.0 the default values has been changed from mysql_native_password to caching_sha2_password

this needs to be reverted in the cnf file

for my installation /etc/mysql/my.cnf is a symbolic link to /etc/alternatives/my.cnf which is a symbolic link to /etc/mysql/mysql.cnf

so we need to edit the file /etc/mysql/mysql.cnf

add the following at the end of the file

[mysqld]

default_authentication_plugin=mysql_native_password

the group [mysqld] is for the server, for the client the group is [mysql]

possible places of the cnf file

• /etc/my.cnf
• /etc/mysql/my.cnf
• $MYSQL_HOME/my.cnf
• [datadir]/my.cnf
• ~/.my.cnf
