1. 启动临时容器把容器内原始配置拷贝到宿主机

docker run --rm apache/rocketmq:4.7.1 cat /home/rocketmq/rocketmq-4.7.1/conf/broker.conf > ./rmqdata/broker/conf/broker.conf

docker run --rm apache/rocketmq:4.7.1 cat /home/rocketmq/rocketmq-4.7.1/conf/plain_acl.yml > ./rmqdata/broker/conf/plain_acl.yml

docker run --rm apache/rocketmq:4.7.1 cat /home/rocketmq/rocketmq-4.7.1/conf/tools.yml > ./rmqdata/broker/conf/tools.yml

2. 验证是否是文件（重点，防止再次变成目录）

ls -l ./rmqdata/broker/conf/broker.conf

chmod -R 777 ./rmqdata

3. 配置文件

/data/rmqdata/
├── broker
    └── conf/broker.conf
    └── conf/plain_acl.yml
    └── conf/tools.yml
├── namesrv
└── rocketmq-dashboard-data
    └── users.properties

# 节点角色：ASYNC_MASTER(异步主) / SYNC_MASTER(同步主) / SLAVE(从节点)
