之前按网上方法更换源 都有问题 这个试过了是可以的
一、进入yum.repo.d
[root@node-01 ~]# cd /etc/yum.repos.d/ [root@node-01 yum.repos.d]# ls CentOS-Base.repo CentOS-Sources.repo
二、备份原yum源
[root@node-01 yum.repos.d]# mkdir yum-back [root@node-01 yum.repos.d]# mv CentOS-* yum-back/ [root@node-01 yum.repos.d]# ls yum-back
三、替换yum源为阿里源
[root@node-01 yum.repos.d]# cat CentOS-Base.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-$releasever - Base baseurl=https://mirrors.aliyun.com/centos-altarch/$releasever/os/$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=https://mirrors.aliyun.com/centos-altarch/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=https://mirrors.aliyun.com/centos-altarch/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 enabled=1 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=https://mirrors.aliyun.com/centos-altarch/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
[root@node-01 yum.repos.d]# cat epel.repo [epel] name=Extra Packages for Enterprise Linux 7 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch #metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 [epel-debuginfo] name=Extra Packages for Enterprise Linux 7 - $basearch - Debug #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch/debug #metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1 [epel-source] name=Extra Packages for Enterprise Linux 7 - $basearch - Source #baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/SRPMS #metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1
四、运行yum生成缓存
[root@node-01 ~]# yum makecache [root@node-01 ~]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7-aarch64 [root@node-01 ~]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
五、验证
[root@node-01 ~]# yum -y install gcc-c++ Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package gcc-c++.aarch64 0:4.8.5-36.el7 will be installed --> Processing Dependency: libstdc++-devel = 4.8.5-36.el7 for package: gcc-c++-4.8.5-36.el7.aarch64 --> Processing Dependency: libstdc++ = 4.8.5-36.el7 for package: gcc-c++-4.8.5-36.el7.aarch64 --> Processing Dependency: gcc = 4.8.5-36.el7 for package: gcc-c++-4.8.5-36.el7.aarch64 ...... ...... ......
