【故障集合】MySQL错误集合（持续补充中）

1、Operation DROP USER failed for ''@'location' #操作删除用户失败

mysql删除语句单词写错了，正确的是drop user ''@'localhost'

MariaDB [(none)]> drop user ''@'location';
ERROR 1396 (HY000): Operation DROP USER failed for ''@'location'
MariaDB [(none)]> 

2、Access denied for user 'root'@'localhost' (using password: YES)" when trying to connect

用root”@“localhost”访问被拒绝

原因：密码错误

[root@web01 ~]# mysqldump -uroot -p -A >/root/all.sql
Enter password: 
mysqldump: Got error: 1045: "Access denied for user 'root'@'localhost' (using password: YES)" when trying to connect
