一、新建用户

CREATE USER 'username'@'host' IDENTIFIED BY 'password';

username:用户名

host:允许在那些ip登录(%)

password:密码

'username'和@和'host'之间没有空格

GRANT privileges ON databasename.tablename TO 'username'@'host';
FLUSH PRIVILEGES;

privileges:具体权限SELECT,INSERT,UPDATE,DELETE,CREATE,DROP(ALL)

databasename:数据库名(*)

tablename:表名(*)

FLUSH PRIVILEGES;

databasename:数据库名(*)
