第一种方式:
1.首先停止MySQL服务:service mysqld stop
2.加参数启动mysql:/usr/bin/mysqld_safe --skip-grant-tables &
然后就可以无任何限制的访问mysql了
3.root用户登陆系统:mysql -u root -p mysql
4.切换数据库:use mysql
5.显示所有的表:show tables;
这里就可以访问表了
6.查看user表中root用户的localhost权限:select * from user where user=‘root‘ and host=‘localhost‘
7.在显示的列表中显示:root用户的localhost的权限都是‘N‘,表示root用户本地登陆不具有权限
8.修改root用户的localhost权限:
update user set
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‘,
Alter_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‘,
Event_priv
= ‘Y‘,
Trigger_priv
= ‘Y‘,
Create_tablespace_priv
= ‘Y‘
where user=‘root‘ and host=‘localhost
9.更新一下:flush privileges;
10.然后重新启动下mysql,可以解决问题了
第二种方式:
使用vim编辑器打开MariaDB的配置文件my.cnf,路径一般为/etc/my.cnf:
在文件中找到 [mysqld] 部分,如果找不到该部分,可以在文件末尾添加以下内容:
[mysqld]
skip-grant-tables
这里的 skip-grant-tables 参数用于跳过登录认证。保存并关闭文件。
重启MariaDB服务,使配置生效:
systemctl restart mariadb
