用rsync同步公网centos yum源做本地yum源服务器
1，安装httpd，rsync，vsftpd
yum -y install httpd rsync vsftpd
mkdir /var/www/html/centos
#由于vsftpd不支持软连接改变目录，所以下面操作效果一样
mount --bind /var/www/html/centos /var/ftp/pub
chkconfig httpd on
chkconfig vsftpd on
service httpd start
service vsftpd start
2，rsync同步脚本如下
#!/bin/bash
# base value
# 要同步的源
YUM_SITE="rsync://mirrors.kernel.org/centos/"
# 本地存放目录
LOCAL_PATH="/u01/mirrors/centos/"
# 需要同步的版本，我只需要5和6还有7版本的总共大概120G左右，去掉iso后会少点
LOCAL_VER="5 5* 6 6* 7 7*"
# 同步时要限制的带宽
BW_limit=512
# 记录本脚本进程号
LOCK_FILE="/var/log/yum_server.pid"
# 如用系统默认rsync工具为空即可。
# 如用自己安装的rsync工具直接填写完整路径
RSYNC_PATH=""
# check update yum server pid
MY_PID=$$
if [ -f $LOCK_FILE ]; then
get_pid=`/bin/cat $LOCK_FILE`
get_system_pid=`/bin/ps -ef|grep -v grep|grep $get_pid|wc -l`
if [ $get_system_pid -eq 0] ; then
echo $MY_PID>$LOCK_FILE
else
echo "Have update yum server now!"
exit 1
fi
else
echo $MY_PID>$LOCK_FILE
fi
# check rsync tool
if [ -z $RSYNC_PATH ]; then
RSYNC_PATH=`/usr/bin/whereis rsync|awk ‘ ‘‘{print $2}‘`
if [ -z $RSYNC_PATH ]; then
echo ‘Not find rsync tool.‘
echo ‘use comm: yum install -y rsync‘
fi
fi
# sync yum source
for VER in $LOCAL_VER;
do
# Check whether there are local directory
if [ ! -d "$LOCAL_PATH$VER" ] ; then
echo "Create dir $LOCAL_PATH$VER"
`/bin/mkdir -p $LOCAL_PATH$VER`
fi
# sync yum source
echo "Start sync $LOCAL_PATH$VER"
$RSYNC_PATH -avrtH --delete --bwlimit=$BW_limit --exclude "isos" $YUM_SITE$VER $LOCAL_PATH
done
# clean lock file
`/bin/rm -rf $LOCK_FILE`
echo ‘sync end.‘
exit 1
3，计划任务
每天凌晨更新
23 59 * * * /root/yumrsync
4，客户端配置
编辑/etc/yum.repos.d/CentOS-Base.repo
find /etc/yum.repos.d/ -type f -name "*.repo" -exec cp {} {}.bak \;
find /etc/yum.repos.d/ -name "*.repo" | xargs sed -i ‘s/#baseurl=http:\/\/mirror.centos.org/baseurl=http:\/\/192.168.0.100/g‘
可用上面命令修改，得到结果如下：
#base
[base]
name=CentOS-$releasever – Base
baseurl=http://192.168.0.100/centos/$releasever/os/$basearch/
enabled=1
