centos 7 yum error CentOS7 Local yum的一次报错信息

发布时间:2017-06-11 来源:服务器之家

说明:今天在火车上测试一个CentOS7下的一个服务,要用到yum配置,但是本机没有联网,所以考虑到配置本地yum,按照之前CentOS6下的常规方法,居然发现有报错。
操作如下:

1)虚拟机下将CentOS7光盘加载到系统里面,然后挂载到本地的/localyum上
[root@localhost yum.repos.d]# mount /dev/cdrom /localyum

2)添加一个repo文件
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim CentOS7-local.repo
[localyum]
name=localyum
baseurl=file:///localyum/
gpgcheck=0
enabled=1

3)测试安装下vsftpd软件
[root@localhost yum.repos.d]# yum -y install vsftpd
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. Disable the repository, 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>
4. 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

4)由于是在局域网内,无法正常连上外网,所有重新调整了下repo文件
[root@localhost yum.repos.d]# vim CentOS7-local.repo
[localyum]
name=localyum
baseurl=file:///localyum/
gpgcheck=0
enabled=1
yum --disablerepo=\* --enablerepo=localyum clean all #清除缓存
yum --disablerepo=\* --enablerepo=localyum makecache #缓存本地yum源包信息

5)重新安装下vsftpd软件
[root@localhost yum.repos.d]# yum -y install vsftpd

6)配置光盘开机自动挂载
[root@localhost ~]# echo "/dev/cdrom /localyum iso9660 defaults 0 0">>/etc/fstab
[root@localhost ~]# mount -a
