安装docker时候遇到的

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package 7:lvm2-2.02.186-7.el7_8.2.x86_64 already installed and latest version
Nothing to do
 

 

可能是加载插件的问题Loaded plugins

禁用插件

1.修改插件的配置文件

vim /etc/yum/pluginconf.d/fastestmirror.conf

enabled = 0//由1改为0,禁用该插件

 

2.修改yum的配置文件

vim /etc/yum.conf

plugins= 0//改为0,不使用插件

 

 

还不行的话

可能缺乏epel
EPEL (Extra Packages for Enterprise Linux)是基于Fedora的一个项目,为“红帽系”的操作系统提供额外的软件包,适用于RHEL、CentOS和Scientific Linux.

yum install epel-release
[root@localhost ~]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2 Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
