镜像源配置文件在 /etc/yum.repos.d 文件夹下 查看yum源文件 ls /etc/yum.repos.d/阿里云镜像配置文件的路径为： http://mirrors.aliyun.com/repo/Centos8.repo 下载阿里镜像源 curl -o /etc/yum.repos.d/CentOS-Base-Aliyun.repo http://mirrors.aliyun.com/repo/Centos-8.repo打开阿里镜像源文件查看更新镜像源信息，我们可以看到阿里的镜像源中已经配置了[base][extras][centosplus][PowerTools][AppStream]源，系统中原本自带的镜像源就可以屏蔽掉，防止镜像冲突。 cat CentOS-Base-Aliyun.repo # CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base - mirrors.aliyun.com failovermethod=priority baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/ http://mirrors.aliyuncs.com/centos/$releasever/BaseOS/$basearch/os/ http://mirrors.cloud.aliyuncs.com/centos/$releasever/BaseOS/$basearch/os/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - mirrors.aliyun.com failovermethod=priority baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/os/ http://mirrors.aliyuncs.com/centos/$releasever/extras/$basearch/os/ http://mirrors.cloud.aliyuncs.com/centos/$releasever/extras/$basearch/os/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - mirrors.aliyun.com failovermethod=priority baseurl=https://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/os/ http://mirrors.aliyuncs.com/centos/$releasever/centosplus/$basearch/os/ http://mirrors.cloud.aliyuncs.com/centos/$releasever/centosplus/$basearch/os/ gpgcheck=1 enabled=0 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official [PowerTools] name=CentOS-$releasever - PowerTools - mirrors.aliyun.com failovermethod=priority baseurl=https://mirrors.aliyun.com/centos/$releasever/PowerTools/$basearch/os/ http://mirrors.aliyuncs.com/centos/$releasever/PowerTools/$basearch/os/ http://mirrors.cloud.aliyuncs.com/centos/$releasever/PowerTools/$basearch/os/ gpgcheck=1 enabled=0 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official [AppStream] name=CentOS-$releasever - AppStream - mirrors.aliyun.com failovermethod=priority baseurl=https://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/ http://mirrors.aliyuncs.com/centos/$releasever/AppStream/$basearch/os/ http://mirrors.cloud.aliyuncs.com/centos/$releasever/AppStream/$basearch/os/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official和原始镜像源文件比较，需要把AppStream.repo Extras.repo Base.repo PowerTools.repo Plus.repo 等处理掉，不然会跟阿里云配置文件里面重复 cd /etc/yum.repos.d mv CentOS-Linux-AppStream.repo CentOS-Linux-AppStream.repo_bak mv CentOS-Linux-BaseOS.repo CentOS-Linux-BaseOS.repo_bak mv CentOS-Linux-Extras.repo CentOS-Linux-Extras.repo_bak mv CentOS-Linux-PowerTools.repo CentOS-Linux-PowerTools.repo_bak mv CentOS-Linux-Plus.repo CentOS-Linux-Plus.repo_bak yum makecache完成 |
