运行服务器之前的 RabbitMQ enagle 功能标志

Question

我尝试在更新后启动rabbitmq-server并收到此错误。

我在官方文档中找到的解决方案是使用rabbitmqctl或web插件。

我尝试使用rabbitmqctl 时遇到错误。据我了解，它无法连接到服务器，并且在找到添加必要功能标志的方法之前我无法启动服务器

如果您已经在 MAC 上安装了rabbitMQ，请按照以下说明解决错误

首先停止rabbitmq并卸载

brew services stop rabbitmq
brew uninstall rabbitmq

删除rabbitMQ的所有引用

rm -rf /opt/homebrew/etc/rabbitmq
rm -rf /opt/homebrew/etc/rabbitmq/enabled_plugins
rm -rf /opt/homebrew/etc/rabbitmq/enabled_plugins.default
rm -rf /opt/homebrew/etc/rabbitmq/rabbitmq-env.conf
rm -rf /opt/homebrew/etc/rabbitmq                
rm -rf /opt/homebrew/var/lib/rabbitmq
rm -rf /opt/homebrew/var/log/rabbitmq

安装rabbitMQ的新副本

brew update
brew install rabbitmq
brew services start rabbitmq
