centos7配置本地yum源（ISO镜像版）

centos7配置本地yum源（ISO镜像版）

背景：

由于本地的centos选择的是最小化安装，很多的包是没有的，比如常用的wget，gcc等等，所以需要使用iso镜像配置下本地yum源。

1、下载centos镜像

**

注意下镜像不能是mini版的，要用dvd或者everything版的，mini版很多包是缺失的

**
镜像地址：https://mirrors.aliyun.com/centos/7/isos/x86_64/?spm=a2c6h.25603864.0.0.200e4511qh3X7S

2、虚拟机加载ISO镜像

3、挂载IOS镜像

mkdir /mnt/iso
mount -o loop /dev/cdrom /mnt/iso
df -lh

4、修改yum源

# 备份cd /etc/yum.repos.d/
lscp CentOS-Base.repo CentOS-Base.repo.default

vi CentOS-Base.repo

修改后的文件如下：

[base]name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infrabaseurl=file:///mnt/iso
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates[updates]name=CentOS-$releasever - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infrabaseurl=file:///mnt/iso
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful[extras]name=CentOS-$releasever - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infrabaseurl=file:///mnt/iso
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages[centosplus]name=CentOS-$releasever - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infrabaseurl=file:///mnt/iso
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

5、更新yum源配置

yum clean all
yum makecache

6、测试本地yum源

# 安装wget
yum install -y wget
