问题 I have installed a mosquitto server on a raspberry server. This server works fine: I have test with mosquitto_sub and mosquitto_pub commands.

Signing certificate by self signed CA

问题 I have created selfsigned CA certificate on Ubuntu that runs on AWS . I have also created client and server certificates signed by current CA. SSL connection is used by Mosquitto MQTT service. Unfortunatly I have Received fatal alert: unknown_ca error from client side when it tries to connect to server. I was tested the same certificate generation procedure on my Raspberry Pi and SSL+MQTT works well. Creating certificates: # CA openssl req -new -newkey rsa:2048 -keyout private/cakey.pem -out

在Windows下使用MQTT

由 笑着哭i 提交于 2020-01-23 22:48:51
在此处https://mosquitto.org/download/下载mqtt windows broker。 安装完毕后在服务中 启动mqtt服务。 如果未在服务列表中出现，则需要 C:\Program Files\mosquitto\mosquitto install C:\Program Files\mosquitto\mosquitto uninstall 这两条命令用来安装和卸载mqtt服务。 密码配置 在mosquitto目录下新建一个password.file文件，输入命令 注意，如果需要增加多个密码，需要去掉-c参数 https://www.cnblogs.com/saryli/p/9820532.html .\mosquitto_passwd -c G:\MQTT_SERVER\mosquitto sammy 根据提示输入密码 修改mosquitto.conf文件 改为 allow_anonymous false password_file G:\MQTT_SERVER\mosquitto\password.file 到此，配置完成。 注意：不用配置ip地址和端口信息，就可以用内网ip地址链接到此mqtt服务器。 来源： CSDN 作者： link2dream 链接： https://blog.csdn.net/xuancuocui1413/article

MQTT (Mosquitto) Connection pool?

由 蹲街弑〆低调 提交于 2020-01-06 20:24:29
问题 What would you suggest for Mosquitto connection pooling in Java? We are wasting (blocking) too much time on establishing each connection, so we think some kind of reuse would be better. 回答1: I'd suggest using the generic object pooling in the Apache commons tools https://commons.apache.org/proper/commons-pool/ But also you could extend Thread to instantiate a MQTT connection object on creation and have a persistent connection per thread. This could be combined with the built in thread pool in
