docker部署rabbitmq出错touch: cannot touch ‘/etc/rabbitmq/rabbitmq.conf‘: Permission denied

首先拉取镜像，这里我使用docker-compose直接拉取

version: '3'
services:

  rabbitmq:
    image: hub.commchina.net/library/rabbitmq:3.8.1-alpine
    container_name: rabbitmq
    environment:
      - RABBITMQ_DEFAULT_USER=admin
      - RABBITMQ_DEFAULT_PASS=admin
    restart: always
    ports:
      - "15672:15672"
    volumes:
      - ./rabbitmq/data:/var/lib/rabbitmq
      - ./rabbitmq/conf:/etc/rabbitmq

挂载的文件卷信息：

./rabbitmq/conf/rabbitmq.conf

loopback_users.guest = false
listeners.tcp.default = 5672
default_pass = admin
default_user = admin
management.tcp.port = 15672

启动镜像：docker-compose -f docker-compose-rabbitmq.yaml up -d

报错信息如下

touch: cannot touch '/etc/rabbitmq/rabbitmq.conf': Permission denied
WARNING: '/etc/rabbitmq/rabbitmq.conf' is not writable, but environment variables have been provided which request that we write to it
  We have copied it to '/tmp/rabbitmq.conf' so it can be amended to work around the problem, but it is recommended that the read-only source file should be modified and the environment variables removed instead.

以为是权限不够所以加了–privileged=true还是不行

报错原因：最后发现是映射的目录./rabbitmq的conf和data没有创建修改权限
解决方法：
chmod说明(u:与文件属主拥有一样的权限[a:所有人]；+:增加权限;rwx:可读可写可执行）-R:递归所有目录和文件

进入到rabbitmq的目录中，执行下面命令。意思就是改变data和conf文件夹的权限，使有权限访问此文件夹。

[root@monsvr rabbitmq]# chmod a+rwx -R data
[root@monsvr rabbitmq]# chmod a+rwx -R conf
