mysql root delete Serve user

本文出现的问题有: 1, root(localhost) 用户被删除; 2, 在关闭mysql服务过后, 无法启动,出现1067错误; 我使用的mysql版本为5.6; mysql的安装路径:C:\Program Files (x86)\MySQL; mysql数据路径:C:\ProgramData\MySQL; my.ini就在数据路径当中; 无法启动mysql

本文出现的问题有:

1, root(localhost) 用户被删除; 

2, 在关闭mysql服务过后, 无法启动,出现1067错误;


我使用的mysql版本为5.6;

mysql的安装路径: C:\Program Files (x86)\MySQL;

mysql数据路径: C:\ProgramData\MySQL;

my.ini就在数据路径当中;


无法启动mysql服务,出现1067,的解决办法:

删除数据目录下,data目录下的ib_logfile0和ib_logfile1文件。


root用户被删除的解决办法:


1, 关闭mysql服务;

2, 开启mysql56服务;

3, 在my.ini中的[mysql]后面加入: skip-grant-tables

4, 使用命令行登陆mysql: mysql -uroot -p, 无须密码登陆成功;

5, mysql> use mysql;

Database changed

6, mysql> select * from user;

Empty set (0.00 sec) 

7, mysql> insert into user set user='root',ssl_cipher='',x509_issuer='',x509_subject='';

Query OK, 1 row affected (0.00 sec)

(这时可能会提示某字段如ssl_cipher无默认值, 只要加上,ssl_cipher=''; 其字段如有提示依次添加就OK了)


8, mysql> update user set Host='localhost',select_priv='y', insert_priv='y',update_priv='y',delete_priv='y',create_priv='y',drop_priv='y',reload_priv='y',shutdown_priv='y',Process_priv='y',file_priv='y',grant_priv='y',References_priv='y',index_priv='y',create_user_priv='y',show_db_priv='y',super_priv='y',create_tmp_table_priv='y',Lock_tables_priv='y',execute_priv='y',repl_slave_priv='y',repl_client_priv='y',create_view_priv='y',show_view_priv='y',create_routine_priv='y',alter_routine_priv='y',create_user_priv='y' where user='root';

Query OK, 1 row affected (0.00 sec)



9, 去关闭mysql56服务; (如果没有关闭mysql56,就直接去开启mysql就会出现1067错误)

10, 开启mysql服务;

11, 删除my.ini中的之前的那句话;


正常情况下登陆mysql;

原来的数据全部回来了!!!!!

(此时尚未设置root的密码)


注:

在root没有密码的情况下 输入密码登陆就会失败;
