Mosquitto作为MQTT转发代理

Question

重新启动时，Mosquitto不可靠地转发排队消息（持久化不起作用）

运行蚊子版本:1.4.15

这是最后测试的配置：

port 1883
persistence true
persistence_file /mosquitto.db
persistence_location /etc/mosquitto

autosave_interval 1
autosave_on_changes true

allow_anonymous true

connection iotcluster
address ip:1883

notifications false
keepalive_interval 300
restart_timeout 30
start_type automatic

clientid rabbitmqtt
username user
password password

topic mqtt out 2
try_private true

mosquitto_pub -h localhost -p 1883 -t mqtt -m "Test-Bridge-Online"

Answer 1

在运行了mosquitto版本1.6.10的更新后，仍然没有成功。

我可以分离出主要的问题--数据库在seetings时没有保存：

persistence true
persistence_file /mosquitto.db
persistence_location /etc/mosquitto

autosave_interval 1
autosave_on_changes true

不确定原因，但无法通过上述设置调用数据库保存。

persistence true
persistence_file /mosquitto.db
persistence_location /etc/mosquitto

autosave_interval 300
autosave_on_changes false

# publish a new message
mosquitto_pub -h localhost -p 1883 -t mqtt -m "Test Offline 100" -q 1
# send signal to save database
killall -SIGUSR1 mosquitto

user mosquitto

allow_anonymous true
