使用脚本自建本地yum源

标签：shell   yum   镜像   

  有一段时间连不上网，搭建服务器测试环境所需要的远端yum源也无法连接，于是想到了自建一个本地的yum源来解决这个问题。搭建本地yum源需要两个东西：一个是web服务器，另一个就是rpm包及包元素据。

  搭建web服务器很简单，那么主要就是把远端的yum源镜像到本地，所以，找一块比较大的磁盘做好分区挂载到web服务器根目录下，然后执行脚本镜像远端数据到本地就可以了。根据自己的需求，我需要CentOS6和7两个版本的yum源，其中的源包括base、updates、extras和epel且不需要系统iso镜像。于是，连上一个速度快的网络开始同步吧！脚本的内容如下：

#!/bin/bash
## rsync mirror centos and epel with yun-idc 
## visit http://mirrors.yun-idc.com/centos/6/
##    http://mirrors.yun-idc.com/centos/7/
##    http://mirrors.yun-idc.com/epel/6/
##    http://mirrors.yun-idc.com/epel/7/

Date=`date +%Y-%m-%d`
Dateis=`date +%F-%H:%M:%S`
Logfile="$Logdir/$Date.log"
Resultfile="$Logdir/$Date.log.res"
Checkres(){
    if [ $? == 0 ];then
    echo -e "\033[1;32m $1 Rsync is success! $Dateis\033[0m" >> $Resultfile
  else
    echo -e "\033[1;31m $1 Rsync is fail! $Dateis\033[0m" >> $Resultfile
  fi
}
Checkdir(){
  if [ ! -d $1 ];then
    mkdir -p $1
  fi
}
Checkdir $Logdir
Rsyncrepo(){
  Checkdir $2
  $Rsync $Options $1 $2 |tee $Logfile
  Checkres $1
}
Rsyncrepo rsync://mirrors.yun-idc.com/centos/6/os/x86_64/ $Centos6base
Rsyncrepo rsync://mirrors.yun-idc.com/centos/6/updates/x86_64/ $Centos6updates

#Rsyncrepo rsync://mirrors.yun-idc.com/centos/6/centosplus/x86_64/ $Centos6plus

Rsyncrepo rsync://mirrors.yun-idc.com/epel/6/x86_64/ $Centos6epel
Rsyncrepo rsync://mirrors.yun-idc.com/epel/7/x86_64/ $Centos7epel

接下来配置客户端指向本地yum源就好了，配置文件内容如下：

[base]
name=CentOS-$releasever - Base
baseurl=http://$host/centos/$releasever/os/$basearch/
    http://mirrors.aliyun.com/centos/$releasever/os/$basearch
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#released updates 
[updates]
name=CentOS-$releasever - Updates
baseurl=http://$host/centos/$releasever/updates/$basearch/
    http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
enabled=1
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://$host/centos/$releasever/extras/$basearch/
    http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
gpgcheck=0

#epel
