docker 安装mosquitto MQTT服务器

版本：2.0.14
docker pull eclipse-mosquitto:latest

sudo mkdir /home/dxy/mosquitto
cd /home/dxy/mosquitto
sudo mkdir config
sudo mkdir data
sudo mkdir log

vi ./config/mosquitto.conf

粘贴如下内容:
注意：此处路径都是docker容器中的相对路径，不是自己本地的路径

persistence true
persistence_location /mosquitto/data
log_dest file /mosquitto/log/mosquitto.log

log_dest stdout

listener 1883 //不加这一句会在新版本2.x.x中报错：Error: Address not available

chmod -R 755 /home/dxy/mosquitto
chmod -R 777 /home/dxy/mosquitto/log

sudo docker run -it --name=mosquitto --privileged 
-p 1883:1883 -p 9001:9001 
-v /home/dxy/mosquitto/config/mosquitto.conf:/mosquitto/config/mosquitto.conf 
-v /home/dxy/mosquitto/data:/mosquitto/data 
-v /home/dxy/mosquitto/log:/mosquitto/log 
-d eclipse-mosquitto

-d:在后台运行容器
–name:容器名
-v:将容器内的目录映射到容器外
-p:端口映射

在 /home/dxy/mosquitto/config/mosquitto.conf 中继续添加

# 关闭匿名模式
allow_anonymous false
# 指定密码文件
password_file /mosquitto/config/pwfile.conf

docker exec -it mosquitto sh

touch /mosquitto/config/pwfile.conf
chmod -R 755 /mosquitto/config/pwfile.conf

mosquitto_passwd -b /mosquitto/config/pwfile.conf username(此处为用户名) password（此处为密码）
