emqx使用

1.MySql配置密码认证

CREATE TABLE `mqtt_user` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(100) DEFAULT NULL,
  `password_hash` varchar(100) DEFAULT NULL,
  `salt` varchar(35) DEFAULT NULL,
  `is_superuser` tinyint(1) DEFAULT 0,
  `created` datetime DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `mqtt_username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2.MySql配置授权认证

CREATE TABLE `mqtt_acl` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(100) NOT NULL,
  `permission` varchar(5) NOT NULL,
  `action` varchar(9) NOT NULL,
  `topic` varchar(100) NOT NULL,
  `qos` tinyint(1),
  `retain` tinyint(1),
  INDEX username_idx(username),
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

3.常用命令
默认账户密码:admin public

admins add <Username> <Password> <Tags>         创建 admin 账号

admins passwd <Username> <Password>                重置 admin 密码

admins del <Username>                                            删除 admin 账号
