[CentOS]更新repo源到本地

1 本地目录作为repo源

将repo源更新到本地可以加速rpm包的安装

1. 将包含rpm包的文件夹存在指定目录，（本文中是/opt/centos-repo）

2. 创建centos.repo

在目录/etc/yum.repo.d/下创建repo配置文件centos.repo

[centos]
name=centos
baseurl=file:///opt/centos-repo
gpgcheck=0
enabled=1

3. 创建索引更新索引

[root@node0 centos-repo]# createrepo /opt/centos-repo/; yum clean all;yum makecache

[root@node0 centos-repo]# cat /etc/yum.repos.d/
backup/ centos.repo ceph.repo
[root@node0 centos-repo]# cat /etc/yum.repos.d/centos.repo
[centos]
name=centos
baseurl=file:///opt/centos-repo
gpgcheck=0

[root@node0 centos-repo]#

[root@node0 yum.repos.d]# ls
CentOS-Base.repo CentOS-fasttrack.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-Media.repo epel.repo
CentOS-Debuginfo.repo CentOS-Sources.repo epel-testing.repo
[root@node0 yum.repos.d]#

将如上repo配置文件都移入到backup目录，如下：

[root@node0 yum.repos.d]# ls
backup centos.repo
[root@node0 yum.repos.d]#

2 光盘作为repo源

设置repo源配置文件

在/etc/yum.repo.d/下创建repo源配置文件:cdrom.repo

[cdrom]
name=CentOS7 - cdrom
baseurl=file:///media/
enable=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[root@node0 ~]# yum clean all
[root@node0 ~]# yum makecache
