环境变量中的RabbitMQ日志和Mnesia位置没有反射(reflect)？

Question

我想将 Rabbitmq MNESIA 目录更改为 /disk文件夹而不是默认 /var/lib .我在 /usr/lib/rabbitmq/bin 中做了更改在 rabbitmq-env和

RABBITMQ_MNESIA_BASE=/disk/rabbitmq/
RABBITMQ_LOG_BASE=/disk/rabbitmq/log/

并在重新启动它后

service rabbitmq-server restart
Restarting rabbitmq-server (via systemctl):                [  OK  ]

但是当我检查状态时

      >      service rabbitmq-server status 
WARNING: Removing trailing slash from RABBITMQ_MNESIA_BASE
WARNING: Removing trailing slash from RABBITMQ_MNESIA_BASE
Status of node 'rabbit@ip-10-03-209-294' ...
Error: unable to connect to node 'rabbit@ip-10-03-209-294': nodedown

DIAGNOSTICS
===========

attempted to contact: ['rabbit@ip-10-03-209-294']

rabbit@ip-10-03-209-294:
  * connected to epmd (port 4369) on ip-10-03-209-294
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on ip-10-03-209-294
  * suggestion: start the node

current node details:
- node name: 'rabbitmq-cli-61@10-03-209-294'
- home dir: /var/lib/rabbitmq
- cookie hash: D1JxYyl9vuDgVmH5K4dGyQ==

删除所有更改后，它工作正常。但我希望 MNESIA 目录为/disk。我也重新启动了实例。

尝试执行以下步骤:

/etc/init.d/rabbitmq-server stop

nano /etc/rabbitmq/rabbitmq-env.conf并添加:

RABBITMQ_MNESIA_BASE=/disk/rabbitmq
RABBITMQ_LOG_BASE=/disk/rabbitmq/log

chown rabbitmq:rabbitmq /disk/(and all subdirs)

/etc/init.d/rabbitmq-server start

service rabbitmq-server status

刚刚在我的 debian 上试过:
