1.停止数据库,并在mysql配置文件my.cnf中添加skip-grant-tables参数到[mysqld]配置块中
执行以下命令:./mysql.server stop
2.启动数据库,添加root用户,并授予权限,启动数据库后,可以以密码登陆,并插入一条添加用户名为root的命令,命令执行如下:
1,./mysql.server start
2,./mysql -p
3,insert into user set user=’root’,ssl_cipher=”,x509_issuer=”,x509_subject=”;
添加完成后,对该root用户更新权限,更新权限命令如下:
update user set Host='localhost',select_priv='y', insert_priv='y',update_priv='y', Alter_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';
