最简单的办法,也是最笨的方法,替换mysql数据库中的三个文件
/var/lib/mysql/mysql/ //路径
user.frm、user.MYD、user.MYI //替换这三个文件
附几个错误提示解决办法
1、ERROR 1290 (HY000): The MySQL server is running with the –skip-grant-tables option so it cannot execute this statement.
shell> mysql
mysql> set global read_only=0;
mysql> flush privileges;
mysql> quit
shell> /usr/bin/mysql_secure_installation
2、[ERROR] InnoDB: Cannot create log files because data files are corrupt or the database was not shut down cleanly after creating the data files.
shell> cd /var/lib/mysql
shell> mv ibdata1 ibdata1.bak
3、[ERROR] InnoDB: space header page consists of zero bytes in data file ./ibdata1
innodb_flush_log_at_trx_commit = 2 在此后添加下面内容
innodb_flush_method=normal
4、ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: NO)
shell> /usr/bin/mysql_secure_installation
