今天在docker搭建redis环境的时候，发现yum拉取不到资源，上不到网，报了如下错误：

测试wget

wget http://mirrors.163/.help/CentOS6-Base-163.repo

结果报错

unknown host mirrors.163

测试ping

在容器内部

ping baidu

结果还是失败

ping: unknown host baidu

多开一个终端，进入主机（不是进入容器），进行ping命令测试发现是OK的，基本可以确定是docker的问题了，而不是网络问题

解决方法

停止所有容器，重启docker

service docker restart

内容扩展

Docker容器内不能联网的6种解决方案

1.使用–net:host选项

2.使用–dns选项

3.改dns server

4.不用dnsmasq

5.重建docker0网络

6.直接在docker内修改/etc/hosts
