centos7安装docker ，再下载rabbitmq镜像，启动容器后无法访问容器内的服务，防火墙也关闭了，但是还是不行，后来重新设置了网卡，就可以了，解决过程如下：
#下载镜像
docker pull rabbitmq:3.7.15
#启动docker容器
docker run -d --name rabbitmq --publish 5671:5671 --publish 5672:5672 --publish 4369:4369 --publish 25672:25672 --publish 15671:15671 --publish 15672:15672 rabbitmq:3.7.15
docker exec -it rabbitmq /bin/bash
rabbitmq-plugins enable rabbitmq_management
#访问rabbitmq服务，正常应该是能访问的，实际访问不了
[root@localhost ~]# curl http://127.0.0.1:15672
curl: (56) Recv failure: Connection reset by peer
#停止docker
systemctl stop docker
#docker0
ip link set dev docker0 down
#删除docker0网桥
brctl delbr docker0
#防火墙设置,后来发现这一步不用执行可以
iptables -t nat -F POSTROUTING
#增加docker0 网桥
brctl addbr docker0
#增加网卡
ip addr add 172.16.10.1/24 dev docker0
#启用网卡
ip link set dev docker0 up
#重启docker服务
systemctl restart docker
正常访问
[root@localhost ~]# curl http://127.0.0.1:15672
