在yum文件中保存下载文件的设置详解程序员

第一步：

从rsync协议的yum源，同步脚本如下：

[[email protected] crontab]# cat yum_update.sh 
#!/bin/bash
date=`date +%F`
echo $date > /var/log/yum_update.log
##########Centos
sour_URL=”rsync://centos.ustc.edu.cn/centos”
osList=”6.6″
os_Plant=”x86_64″
cmd=”rsync -avrt “
cmd=${cmd}${sour_URL}”/”${sour_Dir}”/”
outDir=”/home/himalayas/yum/centos/6/”  ### if change ,please notice the line of epel、rpmforge、rpmfusion
for yumdir in os updates extras centosplus contrib;
do
        test -d $outDir/$yumdir || mkdir -p $outDir/$yumdir
        rsync -avrt $sour_URL/$osList/$yumdir/$os_Plant $outDir/$yumdir  >> /var/log/yum_update.log &
done

##########epel
test -d /home/himalayas/yum/epel/6/x86_64 || mkdir -p /home/himalayas/yum/epel/6/x86_64
rsync -avrt –exclude=debug/ –exclude=repoview/ rsync://centos.ustc.edu.cn/fedora/epel/6/x86_64/ /home/himalayas/yum/epel/6/x86_64 >> /var/log/yum_update.log &

##########rpmforge
test -d /home/himalayas/yum/rpmforge/6/rpmforge/x86_64 || mkdir -p /home/himalayas/yum/rpmforge/6/rpmforge/x86_64
test -d /home/himalayas/yum/rpmforge/6/extras/x86_64 || mkdir -p /home/himalayas/yum/rpmforge/6/extras/x86_64
rsync -avrt rsync://mirror.cpsc.ucalgary.ca/dag/redhat/el6/en/x86_64/rpmforge/ /home/himalayas/yum/rpmforge/6/rpmforge/x86_64 >> /var/log/yum_update.log &  ###4678
rsync -avrt rsync://mirror.cpsc.ucalgary.ca/dag/redhat/el6/en/x86_64/extras/ /home/himalayas/yum/rpmforge/6/extras/x86_64 >> /var/log/yum_update.log &

##########rpmfusion
test -d /home/himalayas/yum/rpmfusion/free/x86_64 || mkdir -p /home/himalayas/yum/rpmfusion/free/x86_64
test -d /home/himalayas/yum/rpmfusion/nofree/x86_64 || mkdir -p /home/himalayas/yum/rpmfusion/nofree/x86_64
rsync -avrt rsync://centos.ustc.edu.cn/fedora/rpmfusion/free/el/updates/6/x86_64/ /home/himalayas/yum/rpmfusion/free/x86_64 >> /var/log/yum_update.log &

rsync -avrt rsync://centos.ustc.edu.cn/fedora/rpmfusion/nonfree/el/updates/6/x86_64/ /home/himalayas/yum/rpmfusion/nofree/x86_64 >> /var/log/yum_update.log &

备注：

1，访问这个网址：centos.ustc.edu.cn/centos/ ，当版本更新之后所有的rpm包可能有6.5转到6.6的目录下，这个时候要手工更改变量：osList=”6.6″，然后最好手工执行一次，看是否可以同步更新。

2，可以用如下命令，查看对方rsync源的目录结构和所有rpm包

rsync -avrt rsync://centos.ustc.edu.cn/centos/6.6/os/x86_64

第二步：添加到crontab每天同步一次
