# 把刚才下载好的插件 上传到 linux系统中
# 我是放在 放在 /home/x  目录下的
# 通过docker ps  查看  rabbitmq的容器ID或容器名称
docker cp   宿主文件 rabbitmq容器ID或容器名称:/目录

# 进去rabbitmq的容器中   rabbitmq-Container-A是容器名称
docker exec -it rabbitmq-Container-A /bin/bashcd plugins
ls -l | grep delayed
# 同样是在容器内plugins目录下，执行rabbitmq-plugins enable rabbitmq_delayed_message_exchange，启用插件
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
# 退出容器
# 重启这个容器
docker restart rabbitmq-Container-A
