centos 7-aarch64如何替换yum源

资源编号:570029 热度：379

### 一、进入yum.repo.d
```
cd /etc/yum.repos.d/
ls
 
CentOS-Base.repo  CentOS-Sources.repo
```
### 二、备份原yum源
```
mkdir yum-back
mv CentOS-* yum-back/
```
### 三、替换yum源为阿里源
vim  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.
#

[root@node-01 yum.repos.d]# cat epel.repo

```
### 四、替换认证秘钥
```
curl -o /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7  https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

curl -o /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 https://archive.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7
```
### 五、运行yum生成缓存
```
yum makecache
 
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
 
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
```
### 六、验证
```
yum -y install gcc-c++
 ```
 
 今天在使用yum安装的时候每个安装包都报了Failing package is: kernel-headers-3.10.0-1127.13.1.el7.x86_64
GPG Keys are configured as: http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6错误

记录一下解决办法

在每一个yum命令安装的背后加上--nogpgcheck

例如安装gcc
```
yum install gcc --nogpgcheck
```
