RabbitMQ日誌和Mnesia在環境變量中的位置沒有反映？

Question

我想將Rabbitmq MNESIA目錄更改爲/disk文件夾，而不是默認/var/lib。我沒有在/usr/lib/rabbitmq/bin變更，在rabbitmq-env與

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

而且隨着

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

重新啓動它後，但是，當我檢查的地位

 >  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== 

刪除所有更改後，它是工作正常。但我想MNESIA目錄是/磁盤。我也重新啓動了該實例。

Answer 1

嘗試以下步驟：

1. /etc/init.d/rabbitmq-server stop

2. nano /etc/rabbitmq/rabbitmq-env.conf並添加：

   RABBITMQ_MNESIA_BASE = /磁盤/ RabbitMQ的
   RABBITMQ_LOG_BASE = /磁盤/ RabbitMQ的/日誌

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

4. /etc/init.d/rabbitmq-server start

5. service rabbitmq-server status

剛試過在我的debian：

Answer 2

相反，這些ENV變量

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

嘗試

MNESIA_BASE=/disk/rabbitmq/ 
LOG_BASE=/disk/rabbitmq/log/ 

這至少在我停止並重新啓動後爲我工作。

Answer 3

在CentOS 7.2我也有以禁用SELinux以有工作

Answer 4

我會強烈建議安裝凳子和setroubleshoot服務器並實施SELinux的適當一個完整安全的解決方案。

見https://www.systutorials.com/docs/linux/man/8-rabbitmq_selinux/

隨着一些ansible愛 - 例如：

- name: Enabling Selinux by default 
    selinux: 
    policy: targeted 
    state: enforcing 

- name: selinux | allow selinux rabbitmq_t 
    selinux_permissive: 
    name: rabbitmq_t 
    permissive: true 

- name: Run selinux restore context on /etc 
    shell: "restorecon -Rv /etc/" 

- name: rabbitmq | Fix the SELINUX fcontenxt 
    sefcontext: 
    target: '/var/lib/rabbitmq/(.*)?' 
    setype: rabbitmq_var_lib_t 
    state: present 
    notify: 
    - reset permissions 
    - restart rabbitmq-server 

- name: Allow RabbitMQ Selinux TCP to listen on 
    seport: 
    ports: 5672,15672 
    proto: tcp 
    setype: rabbitmq_port_t 
    state: present
