设置用户名和密码，若客户端登录时，提供的用户名和密码不匹配，将无法连接mosquitto broker。

安装mosquitto时，附带安装了mosquitto_passwd，用户创建用户的可执行文件。

创建两个用户，分别是：admin和mosquitto

创建第一个用户admin：sudo mosquitto_passwd -c /etc/mosquitto/pwfile.example admin

创建第二个用户mosquitto：sudo mosquitto_passwd /etc/mosquitto/pwfile.example mosquitto
(注意：创建第二个用户时，不需要参数-c。若添加了参数-c，那么第一个用户会被第二个用户覆盖)

aclfile.example#

可以限制指定用户对主题的发布或订阅权限。

user admin
topic write device/1001
topic read room/#
user mosquitto
topic readwrite #
