同步本地源可以采用两种方法：

1.rsync

2.reposync

第一种方案参考如下段程序：

#!/bin/bash

#Script name:rsync_yumrepo.sh

RsyncBin="/usr/bin/rsync"

RsyncPerm='-avrt --delete --no-iconv --bwlimit=1000'

Centos_7_epel='/data/yum_repo/Centos-7/epel/'

LogFile='/data/yum_repo/rsync_yum_log'

Date=`date +%Y-%m-%d`

#check

function check {

if [ $? -eq 0 ];then

echo -e "\033[1;32mRsync is success!\033[0m" >>$LogFile/$Date.log

else

echo -e "\033[1;31mRsync is fail!\033[0m" >>$LogFile/$Date.log

}

if [ ! -d "$LogFile" ];then

mkdir $LogFile

#rsync centos 5 base

#echo 'Now start to rsync centos 5 base!' >>$LogFile/$Date.log

#$RsyncBin $RsyncPerm rsync://mirrors.yun-idc.com/centos/5/os/ $Centos_5_base >>$LogFile/$Date.log

#check

#rsync centos 5 epel

echo 'Now start to rsync centos 5 epel!' >>$LogFile/$Date.log

$RsyncBin $RsyncPerm --exclude=SRPMS/ --exclude=ppc64/ rsync://dl.fedoraproject.org/pub/epel/7/x86_64 $Centos_7_epel >>$LogFile/$Date.log

check

语法为：rsync [option] resource destination

rsync comes with ABSOLUTELY NO WARRANTY. This is free software, and you

General Public Licence for details.

rsync is a file transfer program capable of efficient remote update

via a fast differencing algorithm.

Usage: rsync [OPTION]... SRC [SRC]... DEST

or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST

or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST

or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST

or rsync [OPTION]... [USER@]HOST:SRC [DEST]

or rsync [OPTION]... [USER@]HOST::SRC [DEST]

or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]

The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect

to an rsync daemon, and require SRC or DEST to start with a mole name.

rsync将会把resource中的RPM包下载到指定的目录中。

2.reposync

reposync比价简单，其简单用法为rsync -repoid repository-id

可以用yum repolist查看repo的ID

yum repolist

[root@kilo openstack-common]# yum repolist

Failed to set locale, defaulting to C

Loaded plugins: fastestmirror, langpacks

Loading mirror speeds from cached hostfile

repo id repo name status

centos-iso CentOS-ISO 3576

epel Extra Packages for Enterprise Linux 7 - x86_64 8327

epel-debuginfo Extra Packages for Enterprise Linux 7 - x86_64 - Debug 1919

openstack-kilo OpenStack Kilo Repository 280

openstack-kilo-common openstack kilo common 493

repolist: 14595

如上，同步epel到本地当前目录：

reposync -repoid=epel

reposync的前提是先在系统里面安装repository库，然后到远程repository去下载rpm包。例如可以先安装rdo的openstack-kilo库：

yum insatll http://rdo.fedorapeople.org/openstack-kilo/rdo-release-kilo.rpm

安装完成之后将会在/etc/yum.repos.d目录下生成openstack-kilo.repo的文件，此时即可yum repolist 查看到。

3.制作本地yum源

简单创建repository的命令如下：

createrepo -update --baseurl=packages_dir packages_dir #packages_dir是包含所有rpm包的绝对路径

此命令将会把package_dir目录下的包生成repository，在该目录下会生成repodata子目录，然后在/etc/yum.repos.d目录下编辑.repo文件

[openstack-kilo]

name=OpenStack Kilo Repository

#baseurl=http://repos.fedorapeople.org/repos/openstack/openstack-kilo/el7/

baseurl=file:///data/yum_repo/rdo-openstack-kilo/openstack-kilo

skip_if_unavailable=0

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-kilo

然后刷新：yum clean all；yum makecache即可。
