Mosquitto MQTT Server adalah message broker yang bekerja di atas protokol MQTT. MQTT adalah protokol messaging ringan yang standar ISO untuk digunakan di atas protokol TCP/IP. Hal ini banyak digunakan untuk berkomunikasi dengan perangkat Internet of Things. Kami akan menginstal Mosquitto di server Ubuntu 22.04 dan kami akan mengirim pesan dari perangkat lunak MQTT-spy. Mosquitto adalah proyek Eclipse dan didistribusikan dengan lisensi EDL. Jadi mari kita mulai.

Install server Mosquitto MQTT

Instalasi aplikasi pendukung,

sudo su
apt update
locale-gen id_ID.UTF-8

sudo add-apt-repository ppa:mosquitto-dev/mosquitto-ppa
sudo apt -y install mosquitto mosquitto-clients
mosquitto -version

Install Web Manajemen UI

Konfigurasi Mosquitto MQTT Server

Pada dasarnya mosquitto memungkinkan anonymous access.

Jika dibutuhkan, kita bisa membuat password untuk user, misalnya, mqtt-spy,

sudo mosquitto_passwd -c /etc/mosquitto/pwfile mqtt-spy

masukan password untuk mqtt-spy user yang akan digunakan untuk connect dari client. Jika masih belajar ada baiknya password 123456. Untuk percobaan bisa membuat

Buat file konfigurasi Mosquitto MQTT Server,

sudo nano /etc/mosquitto/conf.d/local.conf

Isi dengan

persistence_file mosquitto.db
log_dest syslog
log_dest stdout
log_dest topic
log_type error
log_type warning
log_type notice
log_type information
connection_messages true
log_timestamp true
allow_anonymous true
password_file /etc/mosquitto/pwfile

Setelah config di simpan, jalankan ldconfig

sudo ldconfig

Tambahkan systemd unit file

sudo nano /etc/systemd/system/mosquitto.service

Isi dengan

[Unit]
Description=Insite MQTT Broker

[Service]
ExecStart=/usr/local/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
Restart=always

[Install]
WantedBy=multi-user.target

Jalankan

sudo systemctl start mosquitto.service

Set supaya mosquitto jalan saat boot,

sudo systemctl enable mosquitto.service

Cek status

systemctl status mosquitto.service

Hasilnya kira-kira,

● mosquitto.service - Insite MQTT Broker
     Loaded: loaded (/etc/systemd/system/mosquitto.service; enabled; vendor preset: enabled)

Quick Test

Monitoring

Buka terminal di server, ketik misalnya,

mosquitto_sub -v -t 'esp/test' -u mqtt-spy -P 123456

dimana

-v  verbosity
-t  topik yang di ikuti

coba ketik dari aplikasi java misalnya on, akan keluar

mosquitto_sub -v -t 'esp/est' -u mqtt-spy -P 123456
lampu ON
lampu ON

Posting

Kirim Perintah

mosquitto_pub -t 'esp/test' -u mqtt-spy -P 123456 -m "lampu ON"
