Problem Description:

When testing the port connection curl http://192.168.100.100:1666/ in docker, curl: (7) Failed connect to 192.168.100.100:1666; connection refused.

solution

Reset the docker network card

在这里插入代码片#停止docker
systemctl stop docker
#docker0
ip link set dev docker0 down
#删除docker0网桥
brctl delbr docker0
#新增一个docker0网桥
brctl addbr docker0
#增加网卡(这里ip也完全使用这个)
ip addr add 172.17.0.1/24 dev docker0
#启用网卡
ip link set dev docker0 up
#重启docker服务
systemctl restart docker

problem solved
