rabbitmq-server 不启动 - 无法连接到 epmd / Ubuntu 16.04

Question

我按照本指南https://www.rabbitmq.com/install-debian.html 安装了rabbitmq-server。但是，它不会以错误消息开头：

我尝试在一个清晰的 Ubuntu 实例上进行此安装，但遇到了同样的错误。我用谷歌搜索了错误消息，似乎我的网络设置有问题 - 我想我应该从默认状态更改一些设置。

知道需要改变什么吗？或者我应该第一次尝试哪个设置？

附：我完全是 Unix 新手。对我来说，它只是一个运行 Python 脚本的云环境。

Answer 1

如果它仅适用于 localhost 设置，请查看以下内容：

fgrep BindToDevice /lib/systemd/system/epmd.socket

Answer 2

我通过在文件 rabbitmq-env.conf 中设置 HOSTNAME 解决了我的问题。我不知道到底是什么导致了这个问题。

我的设置：

sudo cat /etc/hostname
76672.localhost

sudo cat /etc/hosts
127.0.0.1   localhost
127.0.1.1   ubuntu16.04 ubuntu16
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
127.0.0.1 76672.local

/etc/rabbitmq/rabbitmq-env.conf
# Empty - if the file is empty rabbitmq doesn't start
HOSTNAME=76672.local # With this rabbitmq doesn't start either
HOSTNAME=localhost # With this all works
