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 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

Kita perlu menambahkan ijin ke mosquitto user pada directory yang relevan.

 sudo mkdir /var/lib/mosquitto/
 sudo chown -R mosquitto:mosquitto /var/lib/mosquitto/

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
