Centos使用yum安装时AppStream报错
想要安装gbd时运行如下语句
# yum install gdb
报错如下
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/CentOS-Epel.repo;
Configuration: OptionBinding with id "failovermethod" does not exist Repository epel is listed more than once in the configuration CentOS Linux 8 - AppStream 27 B/s | 38 B 00:01
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
原因是由于下载镜像有误导致下载不下来
首先进入/ect/yum.repos.d/,ls一下发现有很多repo文件。
什么是repo文件?repo文件是Fedora中yum源(软件仓库)的配置文件,通常一个repo文件定义了一个或者多个软件仓库的细节内容,例如我们将从哪里下载需要安装或者升级的软件包,repo文件中的设置内容将被yum读取和应用!
[root@VM-24-17-centos yum.repos.d]
CentOS-AppStream.repo CentOS-centosplus.repo.rpmsave CentOS-Linux-AppStream.repo CentOS-Linux-Extras.repo CentOS-Linux-PowerTools.repo epel-playground.repo CentOS-AppStream.repo.rpmsave CentOS-Devel.repo.rpmsave CentOS-Linux-BaseOS.repo CentOS-Linux-FastTrack.repo CentOS-Linux-Sources.repo epel.repo CentOS-Base.repo CentOS-Epel.repo CentOS-Linux-ContinuousRelease.repo CentOS-Linux-HighAvailability.repo CentOS-PowerTools.repo.rpmsave epel-testing-modular.repo CentOS-Base.repo.backup.3 CentOS-Extras.repo.rpmsave CentOS-Linux-Debuginfo.repo CentOS-Linux-Media.repo docker-ce.repo epel-testing.repo CentOS-Base.repo.rpmsave CentOS-HA.repo.rpmsave CentOS-Linux-Devel.repo CentOS-Linux-Plus.repo epel-modular.repo
一开始一以为是CentOS-AppStream.repo和CentOS-Base.repo文件的问题,因此通过下面的语句下载了腾讯yum镜像
参考:https://www.cnblogs.com/bpzblog/p/13918199.html
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos8_base.repo
但后来运行发现问题是在 CentOS-Linux-AppStream.repo和CentOS-Linux-BaseOS.repo中。vim一下两个文件进行更改,把mirrorlist注释掉,把baseurl改成腾讯云
baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/AppStream/$basearch/os/
