Ensure the Default Authentication Plugin Is `caching_sha2_password`

SedangLevel 1Otomatistdsql

Deskripsi

The default authentication plugin in MySQL 8.0 is caching_sha2_password, which provides stronger password hashing and challenge-response authentication than mysql_native_password. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5). Also confirm user_auth_plugin = caching_sha2_password in the TDSQL Manager manager.json.
