NanoMQ的安装与部署

本文使用docker进行安装，因此安装之前需要已经安装了docker

拉取镜像

docker pull emqx/nanomq:latest

相关配置及密码认证

创建目录/usr/local/nanomq/conf以及配置文件nanomq.conf、pwd.conf

# #====================================================================
# # MQTT Broker
# #====================================================================
mqtt {
    property_size = 32
    max_packet_size = 10KB
    max_mqueue_len = 2048
    retry_interval = 10s
    keepalive_multiplier = 1.25

    # Three of below, unsupported now
    max_inflight_window = 2048
    max_awaiting_rel = 10s
    await_rel_timeout = 10s
}

listeners.tcp {
    bind = "0.0.0.0:1883"
}

auth {
        allow_anonymous = false # 允许匿名登录
        no_match = allow       # 没有 ACL 规则匹配情况下的默认操作
        deny_action = ignore   # ACL 检查拒绝情况下的默认操作

        cache = {
                max_size = 32        # 客户端可以缓存的最大 ACL 条目数量
                ttl = 1m             # ACL 规则缓存有效时间
        }

        password = {include "/etc/nanomq_pwd.conf"} # 密码存储文件路径
#       acl = {include "/etc/nanomq_acl.conf"}       # ACL 配置文件路径
}

admin: public
client: public

通过 Docker 运行NanoMQ

docker run -d -p 1883:1883 \
           -v /usr/local/nanomq/conf/nanomq.conf:/etc/nanomq.conf\
           -v /usr/local/nanomq/conf/pwd.conf:/etc/nanomq_pwd.conf\
           --name nanomq emqx/nanomq:latest
