Noon Translation: "Unable to load authentication plugin containing SHA2 cipher:"
The permissions plugin caching_sha2_password cannot be loaded.
problem analysis
The default authentication plug-in before 8.0 is mysql_native_password.
The default authentication plug-in after 8.0 is caching_sha2_password
. The reason why an error will be reported here is also mentioned above: when the 5.7 client connects to the 8.0 server, because the default authentication plug-in is different, it will Error causing the plug-in to fail to load
Note: Currently, most MySQL clients have not been upgraded to the 8.0 authentication method, so common connection tools such as Navicat, Sequel Pro, SQLyog, etc. may have this problem.
solve
Change the MySQL 8.0 authentication plug-in back to mysql_native_password
Modify the identity authentication plug-in to mysql_native_password
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password';
Refresh permissions
FLUSH PRIVILEGES;OK, now use Navicat to connect to MySQL and you will be successful.
The final explanation is that your Navicat version is too low (if you use Navicat), that is, the version of the mysql connection client you are using is too low.
