What is changed, added or deleted? (Required)
Which TiDB version(s) do your changes apply to? (Required)
The MySQL command line client (
mysql) as well as thelibmysqlclientclient library have changed their default authentication plugin. See https://dev.mysql.com/doc/refman/8.0/en/upgrading-from-previous-series.html#upgrade-caching-sha2-password for more information about that change.It's no longer possible to connect to a TiDB Server using those clients if the user account has a password set, unless the
default-auth=mysql_native_passwordoption is used.This behavior can be seen in this example:
Note that the error message says "using password: NO", even though a password is given on the command line.
The
--default-auth=mysql_native_passwwordoption allows the connection to succeed:This patch makes several updates to pages in the documentation that deal with MySQL compatibility, setting passwords, and connecting to TiDB using MySQL clients.
