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
Install docker sesuai petunjuk untuk Ubuntu 22.04 - Docker: Instalasi di Ubuntu 22.04
Selanjutnya, install free dan open-source Management UI untuk MQTT Cedalo
sudo docker run -it -v ~/cedalo_platform:/cedalo cedalo/installer:2-linux
Pastikan mosquitto tidak di install dari Docker Cedalo
cd ~/cedalo_platform sudo sh start.sh

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
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,

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