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

name=CentOS-$releasever – Base

baseurl=http://192.168.0.100/centos/$releasever/os/$basearch/

enabled=1
