是的,Ubuntu上的Mosquitto MQTT代理支持SSL/TLS加密

要在Ubuntu Mosquitto中启用SSL/TLS加密,您需要按照以下步骤操作:

  1. 安装Mosquitto和OpenSSL:
sudo apt-get update
sudo apt-get install mosquitto mosquitto-clients openssl
  1. 创建一个证书目录并切换到该目录:
mkdir certs
cd certs
  1. 生成CA证书:
openssl req -new -x509 -days 365 -extensions v3_ca -keyout ca.key -out ca.crt
  1. 生成服务器证书和私钥:
openssl genrsa -out server.key 2048
openssl req -new -out server.csr -key server.key
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 365
  1. 生成客户端证书和私钥:
openssl genrsa -out client.key 2048
openssl req -new -out client.csr -key client.key
openssl x509 -req -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt -days 365
  1. 将证书和私钥复制到Mosquitto配置目录:
sudo cp ca.crt server.crt server.key /etc/mosquitto/certs/
  1. 编辑Mosquitto配置文件(通常位于/etc/mosquitto/mosquitto.conf),添加以下内容以启用SSL/TLS加密:
listener 8883
cafile /etc/mosquitto/certs/ca.crt
certfile /etc/mosquitto/certs/server.crt
keyfile /etc/mosquitto/certs/server.key
require_certificate true
  1. 重启Mosquitto服务:
sudo systemctl restart mosquitto

现在,您的Mosquitto服务器已启用SSL/TLS加密。客户端可以使用以下命令连接到服务器:

mosquitto_pub -h <your_server_ip> -p 8883 -t "topic" -m "message" --cafile ca.crt --cert client.crt --key client.key
mosquitto_sub -h <your_server_ip> -p 8883 -t "topic" --cafile ca.crt --cert client.crt --key client.key

请确保将<your_server_ip>替换为您的Mosquitto服务器的IP地址。
