INSERT INTO user (Host, User, Password) VALUES ( 'localhost', 'root', password ( '123456'));
3, root用户设置权限
update user September Host = '%', SELECT_priv = 'y', insert_priv = 'y', update_priv = 'y', Alter_priv = 'y', delete_priv = 'y', create_priv = 'and' , 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 = 'and' show_db_priv = 'and' super_priv = 'and' create_tmp_table_priv = 'and' Lock_tables_priv = 'and' Execute_priv = 'and' repl_slave_priv = 'and' repl_client_priv = 'and' Create_view_priv = ' and 'Show_view_priv =' y ', create_routine_priv =' y ', alter_routine_priv =' y ', create_user_priv =' and 'where user =' root '; commit;
