Linux CentOs7系统scl镜像源失效问题
1. 问题描述
成功利用下面下令安装scl源后
[root@iZwz946ibli8ikuyqgtc58Z ~]# yum install centos-release-scl-rh
复制代码
尝试利用scl安装redis5,报了下面错误:
[root@iZwz946ibli8ikuyqgtc58Z ~]# yum install rh-redis5-redis
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org?arch=x86_64&release=7&repo=sclo-rh 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: centos-sclo-rh/x86_64
复制代码
上述错误信息表明无法检索镜像列表,原因是 http://mirrorlist.centos.org 已经停止服务了,因此我们必要更改scl源的baseUrl。
2. 解决方案
利用cd下令到下面路径:
cd /etc/yum.repos.d
复制代码
查看是否有CentOS-SCLo-scl-rh.repo这个文件:
[root@iZwz946ibli8ikuyqgtc58Z yum.repos.d]# ls
CentOS-Base.repo CentOS-SCLo-scl-rh.repo epel.repo
复制代码
有的话利用vim编辑该文件:
vim CentOS-SCLo-scl-rh.repo
复制代码
将[centos-sclo-rh]下的内容改为下面内容:
[centos-sclo-rh]
name=CentOS-7 - SCLo rh
baseurl=http://vault.centos.org/centos/7/sclo/$basearch/rh/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo
复制代码
更改完上述设置文件,便可以成功利用yum安装软件了:
[root@iZwz946ibli8ikuyqgtc58Z yum.repos.d]# yum install rh-redis5-redis
Loaded plugins: fastestmirror
