用rsync同步公网centos yum源做本地yum源服务器

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不支持软链接改变目录，所以下面操作效果一样，使内部网络通过http和ftp都可以访问

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="/var/www/html/centos/" # 需要同步的版本，我只需要5和6版本还有7的，总共在120G左右，不包括iso会少点 LOCAL_VER="5 5* 6 6* 7 7*" # 同步时要限制的带宽 BW_limit=2048 # 记录本脚本进程号 LOCK_FILE="/var/log/yum_server.pid" # 同步日志文件 LogFile=/root/rsyumlog/`date +"%Y-%m-%d"`.log # 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 echo "rsync start at $(date +"%Y-%m-%d %H:%M:%S")" >$LogFile echo "--------------------------------------------------" >>$LogFile 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"  >>$LogFile      echo "--------------------------------------------------" >>$LogFile     $RSYNC_PATH -avrtH --delete --bwlimit=$BW_limit  $YUM_SITE$VER $LOCAL_PATH  >>$LogFile done echo "rsync end at $(date +"%Y-%m-%d %H:%M:%S")" >>$LogFile echo "--------------------------------------------------" >>$LogFile 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：
