docker run -it –rm -v /etc/tinydnsdocker:/opt/tinydns jbanetwork/tinydns:latest tinydns-data
docker stop tinydns
docker rm tinydns
docker run -d –read-only -p 53:53/udp –name tinydns –restart=always -v /etc/tinydnsdocker:/opt/tinydns jbanetwork/tinydns:latest

1）create user ‘user1’@’%’ identified by ‘password’;
2） grant all privileges on dbname.* to ‘user1’@’%’;
查看 show grants for ‘user1’;
3） revoke all privileges on dbname.* from ‘user1’@’%’;
查看 show grants for ‘user1’;
4） drop user ‘user1’@’%’

简化的方式是：

1）grant all privileges on ssapi.* to zhangsan@’%’ identified by ‘zhangsanpassword’;
2） drop user ‘zhangsan’;
