step 1.使用 mysqld --skip-grant 命令启动mysql
step 2.使用 mysqldump 将库数据导出
step 3.使用 mysqladmin shutdown 停止mysqld 服务
step 4.在shell 下进入mysql数据目录,删除下面的 mysql 库
step 5.运行 mysql_install_db 重新创建默认的 mysql 库
step 6.运行mysqld服务,检查导入库数据,重新创建库用户、密码以及设置权限
step 7.执行cat /etc/mysql/debian.cnf 查看 debian-sys-maint帐号密码,运行mysql执行如下命令添加帐号
mysql> GRANT ALL PRIVILEGES ON *.*  TO 'debian-sys-maint'@'localhost' IDENTIFIED BY?'前面看到的密码' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
如果已有debian-sys-maint帐号,可以使用如下命令修改密码为前面看到的
mysql>SET PASSWORD FOR 'debian-sys-maint'@'localhost' = PASSWORD('前面看到的密码');
mysql> FLUSH PRIVILEGES;
(如没有重要数据,可以忽略步骤1,2,3)
