今天在docker搭建redis環(huán)境的時候，發(fā)現(xiàn)yum拉取不到資源，上不到網(wǎng)，報了如下錯誤：

測試wget
wget?http://mirrors.163.com/.help/CentOS6-Base-163.repo
結(jié)果報錯
unknown?host?mirrors.163.com
測試ping
在容器內(nèi)部 ping?www.baidu.com
結(jié)果還是失敗
ping:?unknown?host?www.baidu.com
多開一個終端，進入主機（不是進入容器），進行ping命令測試發(fā)現(xiàn)是OK的，基本可以確定是docker的問題了，而不是網(wǎng)絡(luò)問題
解決方法
停止所有容器，重啟docker
service?docker?restart
