安装部署
1.下载软件包后上传到服务器，解压
unzip emqttd-centos7-v2.0.zip
2.以调试模式启动，检查服务是否正常
[root@localhost emqttd]# cd emqttd && ./bin/emqttd console
Exec: /root/emqttd/erts-9.0/bin/erlexec -boot /root/emqttd/releases/2.3.7/emqttd -mode embedded -boot_var ERTS_LIB_DIR /root/emqttd/erts-9.0/../lib -mnesia dir "/root/emqttd/data/mnesia/emq@127.0.0.1" -config /root/emqttd/data/configs/app.2020.05.23.23.38.19.config -args_file /root/emqttd/data/configs/vm.2020.05.23.23.38.19.args -vm_args /root/emqttd/data/configs/vm.2020.05.23.23.38.19.args -- console

3.查看服务启动状态
[root@localhost ~]# ./emqttd/bin/emqttd_ctl status
Node ‘emq@127.0.0.1‘ is started
emqttd 2.3.7 is running
4.如果服务启动正常，更改为后台启动，启动错误日志将输出到log目录下
5.EMQ 消息服务器提供了状态监控 URL
http://localhost:8080/status
6.控制台 URL: http://localhost:18083/ ，默认登录用户名: admin, 密码: public。
7.停止服务器:
调试配置
1.EMQ 2.0 消息服务器默认占用的 TCP 端口包括:
| 1883 |
MQTT 协议端口 |
| 8883 |
MQTT/SSL 端口 |
| 8083 |
MQTT/WebSocket 端口 |
| 8080 |
HTTP API 端口 |
| 18083 |
Dashboard 管理控制台端口 |
2.可通过 etc/emq.conf 配置文件的 ‘listener’ 段落设置（18083是由emq_dashboard插件控制，配置文件在etc/plugins/emq_dashboard.conf）
## TCP Listener: 1883, 127.0.0.1:1883, ::1:1883
listener.tcp.external = 0.0.0.0:1883
## SSL Listener: 8883, 127.0.0.1:8883, ::1:8883
listener.ssl.external = 8883
## External MQTT/WebSocket Listener
listener.ws.external = 8083
## HTTP Management API Listener
listener.api.mgmt = 127.0.0.1:8080
3.EMQ 消息服务器主要配置文件:
| etc/emq.conf |
EMQ 消息服务器参数设置 |
| etc/plugins/*.conf |
EMQ 插件配置文件 |
