宝塔安装

yum install -y wget && wget -O install.sh download.bt.cn/install/ins… && sh install.sh ed8484bec 出现错误

错误：为仓库 'appstream' 下载元数据失败 : Cannot prepare internal mirrorlist: No URLs 

解决办法

1、首先查看系统镜像问题

[root@localhost ~]#  cat CentOS-Linux-BaseOS.repo
cat: CentOS-Linux-BaseOS.repo: 没有那个文件或目录
[root@localhost ~]#  cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
CentOS-Linux-AppStream.repo          CentOS-Linux-Devel.repo             CentOS-Linux-Media.repo
CentOS-Linux-BaseOS.repo             CentOS-Linux-Extras.repo            CentOS-Linux-Plus.repo
CentOS-Linux-ContinuousRelease.repo  CentOS-Linux-FastTrack.repo         CentOS-Linux-PowerTools.repo
CentOS-Linux-Debuginfo.repo          CentOS-Linux-HighAvailability.repo  CentOS-Linux-Sources.repo
[root@localhost yum.repos.d]# cat CentOS-Linux-BaseOS.repo
# CentOS-Linux-BaseOS.repo

# The mirrorlist system uses the connecting IP address of the client and the

# baseurl line instead.

2、切换为阿里云镜像

[root@localhost yum.repos.d]# mkdir backup && mv CentOS-Linux-*.repo backup //备份原来的镜像
[root@localhost yum.repos.d]# yum install wget //验证
错误：在"/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d"中没有被启用的仓库。
[root@localhost yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Linux-Base-ali.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo //切换为阿里云镜像
