个人智能家居系统 - MQTT服务器搭建，centOS7.3

0x00 参考

• 在CentOS7 上安装mosquitto1.4.1服务器，实现MQTT信息推送功能并增加websocket功能

• mosquitto的鉴权配置

0x01 配置

• General configuration

  所见即所得，保持默认即可

• Default listener

  # 设置端口
  port 1883
  # 设置最大连接数
  max_connections -1
  # 使用协议，mqtt或者websocket
  protocol mqtt
  

• SSL/TLS support

  用于 default listerner 的安全设置，暂未设置

• Extra listeners

  用于 websocket ，暂未设置

• SSL/TLS support

  用于 Extra listeners 的安全设置，暂未设置

• Persistence

  持续性设置，即 mosquitto 重启后恢复设置，暂未设置

  而且客户端的断线重连机制更加稳妥

• Logging

  开启服务时重定向 stdout 等信息至文件，这里只设置 type

• Security

  # 设置前缀
  clientid_prefixes guduyl
  # 禁止匿名登录
  allow_anonymous false
  # 设置用户名密码文件
  password_file /etc/mosquitto/pwfile
  # 设置权限信息文件
  acl_file /etc/mosquitto/aclfile
  

• Bridges

  用于分布式服务器，暂未设置

• SSL/TLS support

  分布式服务器安全设置，暂未设置

• External config files

• rsmb options

用户名密码设置

• mosquitto_passwd 命令，查看帮助即可

权限文件设置

• 仿照 aclfile.example 文件

  • test/jh/# 可匹配 test/jh/a/b/c, test/jh/a/b, test/jh/a.test/jh
  • test/jh/+ 可匹配 test/jh/a, test/jh/b, 但是不能匹配 test/jh/a/b
