开启websocket支持,修改配置文件

port 1883
# 配置支持websocket了
listener 8080
protocol websockets

加上ssl协议

vim /etc/mosquitto/mosquitto.conf
#mqtt 协议
port 1883

#mqtt+ssl 
listener 8883
cafile /home/yangjb/apache/1_root_bundle.crt
certfile /home/yangjb/apache/2_www.qilv.group.crt
keyfile /home/yangjb/apache/3_www.qilv.group.key

#websocket 协议
listener 8080
protocol websockets

#websocket+ssl 
listener 8081
protocol websockets
cafile /home/yangjb/apache/1_root_bundle.crt
certfile /home/yangjb/apache/2_www.qilv.group.crt
keyfile /home/yangjb/apache/3_www.qilv.group.key

通过 nginx转发websocket

location /mqtt {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header Sec-WebSocket-Protocol mqtt;
    # 这行就是去除 Sec-WebSocket-Protocol
    more_clear_headers Sec-WebSocket-Protocol;

    proxy_http_version 1.1;
    proxy_set_header Upgrade websocket;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-real-ip $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
}
