错误如图所示:
错误详情信息:
1251 client does not support authentication protocol requested by server;consider upgrading Mysql client ERROR 1396 (HY000): Operation ALTER USER failed for ‘root‘@‘localhost‘
问题原因:
主要是由于mysql8以前的加密规则与mysql8以后的存在差异。
解决办法:
ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘password‘ PASSWORD EXPIRE NEVER; ##修改加密规则 ALTER USER ‘root‘@‘localhost‘ IDENTIFIED WITH mysql_native_password BY ‘password‘; ##更新一下用户的密码 password 为自己想要重新设置的密码 FLUSH PRIVILEGES; ##刷新权限
