问题描述:
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:
http://mirrors.aliyun.com/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.aliyun.com'" Trying other mirror. http://mirrors.neusoft.edu.cn/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.neusoft.edu.cn'" Trying other mirror. http://mirrors.nwsuaf.edu.cn/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.nwsuaf.edu.cn'" Trying other mirror. http://mirrors.shu.edu.cn/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.shu.edu.cn'" Trying other mirror. http://mirrors.sohu.com/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.sohu.com'" Trying other mirror. http://mirrors.tuna.tsinghua.edu.cn/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.tuna.tsinghua.edu.cn'" Trying other mirror. http://mirrors.zju.edu.cn/centos/6.10/extras/x86_64/Packages/epel-release-6-8.noarch.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.zju.edu.cn'" Trying other mirror.
解决过程:
1、测试wget
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
结果报错
unknown host mirrors.163.com
2、测试ping
在容器内部
ping www.baidu.com
结果还是失败
ping: unknown host www.baidu.com
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即可。
service docker restart
完成!
