將上述代碼保存爲makefile.shvim

作以下修改，終端執行。服務器

修改 CN 域中 IP 地址爲你主機/設備的 IP 地址
[可選]加密位數 1024 修改成你須要的加密位數

2. CA校驗證書測試

進行以下測試，以驗證證書是否可用：ide

$openssl verify -CAfile ca/ca.crt server/server.crt

$openssl verify -CAfile ca/ca.crt client/client.crt

3.配置單/雙向認證

step 1.進入配置文件測試

sudo vim /etc/mosquitto/mosquitto.conf

step 2.找到 Default listener,在該欄下進行以下配置,再找到Certificate based SSL/TLS support字段.ui

port 8883

cafile /etc/mosquitto/CA/ca.crt

certfile /etc/mosquitto/CA/server/server.crt

keyfile /etc/mosquitto/CA/server/server.key

require_certificate true

use_identity_as_username true

根據本身路徑不一樣配置校驗文件路徑，筆者是把文件放在/etc/mosquitto/CA/下this

注意!!!

根據單向認證和雙向認證須要，可能需修改的字段有： a) port 8883 // MQTT服務器將選擇此端口 listen b) cafile /etc/mosquitto/CA/ca.crt加密

雙向認證必須配置爲你的CA證書單向認證(一般認爲是client校驗server證書，下同)可選配置單向認證中，server 和 client 端 ca 配置必須保持一致。即 server 若配置 ca.crt ,則 client 必須配置 ca.crt， server 不配置ca.crt ,client 也不可配置 ca.crt 路徑必須爲絕對路徑！！！spa

c) certfile /etc/mosquitto/CA/server/server.crt 單項認證和雙向認證都必須配置爲你的server證書code

d) keyfile /etc/mosquitto/CA/server/server.key 單項認證和雙向認證都必須配置爲你的server私鑰

e) require_certificate true 單向認證需設置爲 false,註釋此行，默認也是 false

雙向認證必須配置爲true f) use_identity_as_username true 單向認證設置爲 false,註釋此行，默認也是 false，注意設置爲false，則須要用戶名和密碼鑑權，反之，則不須要 雙向認證一般設置爲true

step 3.重啓服務

mosquitto -c /etc/mosquitto/mosquitto.conf

若是提示端口被佔用，先ps出mosquitto，再kill掉 ps -aux | grep "mosquitto" kill -9 XXXXX

4.單雙向切換

單向認證只須要註釋兩行便可:

#require_certificate true

#use_identity_as_username true

以下：

port 8883
cafile  /etc/mosquitto/CA/ca/ca.crt
certfile  /etc/mosquitto/CA/server/server.crt
keyfile  /etc/mosquitto/CA/server/server.key

5.同時打開單雙向認證

step 1. 在先將/etc/mosquitto/mosquitto.conf 文件按2.4節配置默認打開雙向認證，再找到 Extra listener字段進行以下配置，打開另外一個端口用做單向認證

step 2. 再在該字段下找到Certificate based SSL/TLS support字段

step 3.重啓服務 mosquitto -c /etc/mosquitto/mosquitto.conf

若是提示端口被佔用，先ps出mosquitto，再kill掉 ps -aux | grep "mosquitto" kill -9 XXXXX

6 驗證

step 1.進入到CA證書目錄下：

step 2.雙向：終端一：訂閱 mosquitto_sub -h 10.30.11.47 -p 8883 -t "mqtt/server/topic" --cafile ./ca/ca.crt --cert ./client/client.crt --key ./client/client.key &

終端二：發佈 mosquitto_pub -h 10.30.11.47 -p 8883 -t "mqtt/server/topic" -m "hello,world!" --cafile ./ca/ca.crt --cert ./server/server.crt --key ./server/server.key

step 3. 單向終端一：訂閱 mosquitto_sub -h 10.30.11.47 -p 8884 -t "mqtt/server/topic" --cafile ./ca/ca.crt &

終端二：發佈 mosquitto_pub -h 10.30.11.47 -p 8884 -t "mqtt/server/topic" -m " hello,world!" --cafile ./ca/ca.crt
