RabbitMQ＃の紹介
- MQはメッセージキューと呼ばれ、[メッセージキュー]（https://cloud.tencent.com/product/cmq?from=10680）（MQ）はアプリケーション間の通信方法です。アプリケーションは、キュー内外のメッセージ（アプリケーションデータ用）の読み取りと書き込みによって通信します。メッセージをリンクするための専用接続は必要ありません。メッセージパッシングとは、相互に直接呼び出して通信するのではなく、メッセージでデータを送信することによるプログラム間の通信を指します。直接呼び出しは通常、リモートプロシージャコールなどのテクノロジで使用されます。キューイングとは、キューを介して通信するアプリケーションを指します。キューを使用すると、受信アプリケーションと送信アプリケーションを同時に実行する必要がなくなります。より成熟したMQ製品には、IBM WEBSPHEREMQなどがあります。
- RabbitMQのメッセージブローカーソフトウェアをインストールして、AMQP（Advanced Message Queuing Protocol）を実装します

Rabbitmq-サーバー起動エラー：RabbitMQブローカーの起動に失敗しました
Du Niang分析：ホスト名が正しく構成されていない、元のホスト名がvdevops.orgである、vdevopsに変更されている、hostsファイルのホスト名設定が変更されている

RabbitMQ：Web UIの使用＃
[ root@vdevops ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.[root@vdevops ~]# systemctl restart rabbitmq-server
- クライアントアクセス
http://vdevops:15672/
rabbitmqadmin use＃
- rabbitmqadminコマンドを使用してRabbitMQを構成できます
WebUIからrabbitmqadminをダウンロードします。 Web UIにログインし、「http：//（ホスト名またはIPアドレス）：15672 / cli」に移動すると、次の画面が表示されます。ここからrabbitmqadminをダウンロードし、右クリックしてrabbitmqadmin.txtを保存し、サーバーにアップロードします。 rabbitmqadminに変更し、実行権限を追加します
- rabbitmqadminをRabbitMQサーバーにアップロードし、適切な権限を設定します。この例は、次の設定を示しています。
[ root@localhost ~]# ll /usr/local/bin/rabbitmqadmin
