RabbitMQ enagle 功能标志在运行服务器之前

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。

我在尝试使用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

$ rabbitmqctl list_feature_flags
Error: {:badrpc, :nodedown}

您必须在升级之前启用所有功能标志。要解决您的情况：

• 降级到您正在使用的 RabbitMQ 版本
• 启用所有功能标志
• 重新进行升级过程

我们正在努力使功能标志启用自动发生 - https://github.com/rabbitmq/rabbitmq-server/issues/5212
