Ошибка API управления RabbitMQ: HTTP 500: ошибка внутреннего сервера

Question

Я использую цветок сельдерея с RabbitMQ в качестве брокера сообщений. Однако я: получает неприятную ошибку

ERROR - RabbitMQ management API call failed: HTTP 500: Internal Server Error

каждый раз, когда я пытаюсь получить доступ к очереди RabbitMQ по интерфейсу управления RabbitMQ (http://localhost:15672/#/queues) или сельдерей Брокер (http://localhost:5555/broker).

Здесь представлена ​​подробная информация журнала: Управление веб-

=ERROR REPORT==== 15-Jan-2017::23:12:19 === webmachine error: path="/api/queues/%2F" {error,{error,function_clause, [{mochijson2,json_encode_string_unicode, [{error,[],<<166,65,92,180,0,0,0,0,0>>}, {encoder,null,false}, """], [{file,"src/mochijson2.erl"},{line,274}]}, {mochijson2,'-json_encode_proplist/2-fun-0-',3, [{file,"src/mochijson2.erl"},{line,198}]}, {lists,foldl,3,[{file,"lists.erl"},{line,1248}]}, {mochijson2,json_encode_proplist,2, [{file,"src/mochijson2.erl"},{line,202}]}, {mochijson2,'-json_encode_proplist/2-fun-0-',3, [{file,"src/mochijson2.erl"},{line,199}]}, {lists,foldl,3,[{file,"lists.erl"},{line,1248}]}, {mochijson2,json_encode_proplist,2, [{file,"src/mochijson2.erl"},{line,202}]}, {mochijson2,'-json_encode_array/2-fun-0-',3, [{file,"src/mochijson2.erl"},{line,189}]}]}}

RabbitMQ дает мне:

Got response code 500 with body {"error":"Internal Server Error","reason":"{error,{error,function_clause,\n [{mochijson2,json_encode_string_unicode,\n [{error,[],<<166,65,92,180,0,0,0,0,0>>},\n {encoder,null,false},\n "\""],\n [{file,"src/mochijson2.erl"},{line,274}]},\n {mochijson2,'-json_encode_proplist/2-fun-0-',3,\n [{file,"src/mochijson2.erl"},{line,198}]},\n {lists,foldl,3,[{file,"lists.erl"},{line,1248}]},\n {mochijson2,json_encode_proplist,2,\n [{file,"src/mochijson2.erl"},{line,202}]},\n {mochijson2,'-json_encode_proplist/2-fun-0-',3,\n [{file,"src/mochijson2.erl"},{line,199}]},\n {lists,foldl,3,[{file,"lists.erl"},{line,1248}]},\n {mochijson2,json_encode_proplist,2,\n [{file,"src/mochijson2.erl"},{line,202}]},\n {mochijson2,'-json_encode_array/2-fun-0-',3,\n [{file,"src/mochijson2.erl"},{line,189}]}]}}\n"}

Я использую:

• Ubuntu 14.04
• Python 2.7.6
• Цветок 0.9.1
• сельдерея 4.0.2
• RabbitMQ 3.6.6
• Эрланга/ОТП 19

плагин управления RabbitMQ включен (RabbitMQ-плагинов позволяют rabbitmq_management).

Вот выход для состояния rabbitmqctl:

Вот как я бегу сельдерей:

Start 3 рабочих сельдерея:

celery worker -A celeryapp --config celeryconfig --workdir /proj -l DEBUG --soft-time-limit=3500 --time-limit=3600 --autoscale=2,1 -S /proj/states.db -s /proj/celerybeat-schedule.db -f /proj/logs/celery_worker_1_%n%I.log --pidfile /tmp/celery_w1.pid -n worker1@%d 
celery worker -A celeryapp --config celeryconfig --workdir /proj -l DEBUG --soft-time-limit=3500 --time-limit=3600 --autoscale=2,1 -S /proj/states.db -s /proj/celerybeat-schedule.db -f /proj/logs/celery_worker_2_%n%I.log --pidfile /tmp/celery_w2.pid -n worker2@%d 
celery worker -A celeryapp --config celeryconfig --workdir /proj -l DEBUG --soft-time-limit=3500 --time-limit=3600 --autoscale=2,1 -S /proj/states.db -s /proj/celerybeat-schedule.db -f /proj/logs/celery_worker_3_%n%I.log --pidfile /tmp/celery_w3.pid -n worker3@%d 

Начало сельдерей биений:

celery beat -A celeryapp --config celeryconfig --workdir /proj -l DEBUG -s /proj/celerybeat-schedule.db -f /proj/logs/celery_%n%I.log --pidfile /tmp/celery.pid 

Начало сельдерея цветка:

celery flower -A celeryapp --workdir=/proj/ --broker=amqp://guest:guest@localhost:5672// --broker-api=http://guest:guest@localhost:15672/api/ --db=/proj/flower.db --logging=debug --basic-auth=guest:guest 

Я отвечал на этот вопрос в GitHub вопросах RabbitMQ, но это было rejected

Answer 1

Вашего Elang версия это немного старая.

Update это с помощью последней версии, интерфейс управления требует новой версии Erlang

https://www.erlang-solutions.com/resources/download.html

wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb 
sudo dpkg -i erlang-solutions_1.0_all.deb 
sudo apt-get update 
sudo apt-get install erlang
