Come installare RabbitMQ in OpenSUSE Leap 15.3

RabbitMQ è un software broker di messaggi open source che implementa l'Advanced Message Queuing Protocol (AMQP). RabbitMQ funziona ricevendo messaggi dagli editori (applicazioni che li pubblicano) e li indirizza ai consumatori (applicazioni che li elaborano).

1. Aggiornamento del sistema

Prima di procedere, assicurarsi che i pacchetti del server siano aggiornati. Usa questo comando per ottenere ciò:

sudo zypper ref
sudo zypper up -y

2. Installazione di Erlang

Il pacchetto RabbitMQ si trova nei repository OpenSUSE predefiniti. Installalo usando questo comando:

sudo zypper install -y erlang

5. Avvio e abilitazione del servizio rabbitmq-server

Avvia il servizio

sudo systemctl start rabbitmq-server

Quindi controlla lo stato per confermarne l'esecuzione

~> sudo systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ broker
     Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; disabled; vendor preset: disabled)
     Active: active (running) since Sun 2021-11-14 17:46:33 UTC; 10s ago
   Main PID: 2478 (beam.smp)

Nov 14 17:46:26 ip-10-2-40-188 systemd[1]: Starting RabbitMQ broker...
Nov 14 17:46:33 ip-10-2-40-188 systemd[1]: rabbitmq-server.service: Supervising process 2478 which is not our child. We'll most likely not notice when it exits.
Nov 14 17:46:33 ip-10-2-40-188 systemd[1]: Started RabbitMQ broker.

Ora puoi abilitarlo all'avvio

sudo systemctl enable rabbitmq-server

Puoi ottenere lo stato degli interni di Rabbitmq:

$ sudo rabbitmqctl status

6. Opzionale:abilitazione del dashboard RabbitMQ

Usa il rabbitmq-plugins enable comando per abilitare la dashboard di gestione:

~> sudo rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node [email protected]:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to [email protected]
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

set 3 plugins.
Offline change; changes will take effect at broker restart.

Il servizio web è in ascolto sulla porta 15672

$ ss -tunlp | grep 15672
tcp   LISTEN 0      128          0.0.0.0:15672      0.0.0.0:*

Se hai un servizio Firewalld attivo, consenti le porte 5672 e 15672

$ ss -tunlp | grep 15672
tcp   LISTEN 0      1024         0.0.0.0:15672      0.0.0.0:*

Accedi aprendo l'URL http://[server IP]:15672 come http://127.0.0.1:15672

Per impostazione predefinita, l'ospite l'utente esiste e può connettersi solo da localhost . Puoi accedere con questo utente in locale con la password "ospite"

Per poter accedere alla rete, crea un utente amministratore come di seguito:

$ sudo rabbitmqctl add_user admin Secr3t
Adding user "admin" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.

$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...

Accedi con questo nome utente amministratore e la password assegnata. Dovresti vedere un'interfaccia simile alla seguente:

7. Comandi di base per la gestione degli utenti di RabbitMQ

Elimina utente:

sudo rabbitmqctl delete_user user

Modifica password utente:

sudo rabbitmqctl change_password user strongpassword

Crea un nuovo host virtuale:

sudo rabbitmqctl add_vhost /my_vhost

Elenca gli host virtuali disponibili:

sudo rabbitmqctl list_vhosts

Elimina un host virtuale:

sudo rabbitmqctl delete_vhost /myvhost

Concedi autorizzazioni utente per vhost:

sudo rabbitmqctl set_permissions -p /myvhost user ".*" ".*" ".*"

Elenca i permessi vhost:

sudo rabbitmqctl list_permissions -p /myvhost

Per elencare le autorizzazioni utente:

rabbitmqctl list_user_permissions user

Elimina le autorizzazioni utente:

rabbitmqctl clear_permissions -p /myvhost user
