这是我的 client.cfg 文件：
main_collective = mcollective
collectives = mcollective
libdir = /usr/share/mcollective/plugins
logger_type = console
loglevel = warn
# Plugins
securityprovider = psk
plugin.psk = unset
connector = rabbitmq
plugin.rabbitmq.pool.size = 1
plugin.rabbitmq.pool.1.host = myserver
plugin.rabbitmq.pool.1.port = 61613
plugin.rabbitmq.pool.1.user = guest
plugin.rabbitmq.pool.1.password = password
# Facts
factsource = yaml
plugin.yaml = /etc/mcollective/facts.yaml
我已经在我的 Puppet Master 服务器上设置了 RabbitMQ 服务器。据我所知，RabbitMQ 配置正确。端口已打开，并准备好接受连接。
在 MCollective 客户端上，我收到以下错误：

如何修复 RabbitMQ 连接器的错误？
谢谢！
