使用docker时报错：YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. Invalid ...

1 全部内容

全部报错是这样的：

YumRepo Error: All mirror URLs are not using ftp, http[s] or file.

Eg. Invalid release/repo/arch combination/

removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt

Error: Cannot find a valid baseurl for repo: base

2 起因与经过

起因是这样的，为了图方便直接下载了docker的官方hadoop镜像，而本萌新以前都是自己配docker自己用的， 也不清楚这个官方hadoop镜像用的是centos，于是在vim core-site.xml遇到了这个报错：

bash-4.1# vim core-site.xml

bash: vim: command not found

这部直接给他下载一个，于是不加思索键入了apt-get install -y vim，不出意料地得到了如下的错误：

bash-4.1# apt-get install -y vim

bash: apt-get: command not found

查了一下，得知这个镜像是centos系统的，当然没有apt-get了，于是键入了如下命令：

yum -y install vim

便有了开头的那段报错 .

3 解决方案

参考了这位老哥的博客：

YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. Invalid release/repo/archhttps://blog.csdn.net/wwzzh1989/article/details/123290331原因就是该版本的centos停止维护了，官方源已经没有用了，所以YUM会报错！！！

解决思路就是去更换yum的源，具体操作如下：

1. 打开yum的配置文件：       

vi /etc/yum.repos.d/CentOS-Base.repo 

2. 注释掉所有以mirrorlist开头的行

3. 解开所有以baseurl开头的行

4. 修改baseurl，参考示例如下：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#

接着，再次运行：

yum -y install vim

发现依然存在问题，报错如下：

于是按照提示尝试：

yum --enablerepo=base clean metadata

再次运行yum -y install vim，发现问题解决了！
