CentOS 8 yum安装软件时，提示无法从AppStream下载

更换国内yum源

# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup.3
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos8_base.repo

　

清理之前的yum缓存

# yum clean all

　　

建立新的缓存

# yum makecache

　　

解决makecahe报错

centos8会出现以下报错

解决办法

  • 将CentOS-AppStream.repo文件中的链接更新
# vim /etc/yum.repos.d/CentOS-AppStream.repo
  • 注释掉原有内容，并插入新内容
#这一段注释掉
#[AppStream]
#name=CentOS-$releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
#mirrorlist=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
#gpgcheck=1
#enabled=1
#pgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

#改为下面这段
[AppStream]
name=Qcloud centos AppStream - $basearch
baseurl=http://mirrors.cloud.tencent.com/centos/$releasever/AppStream/$basearch/os/
enabled=0
gpgcheck=1
gpgkey=http://mirrors.cloud.tencent.com/centos/RPM-GPG-KEY-CentOS-Official
  • 重新运行 # yum makecache
# yum makecache
