在本地搭建YUM仓库并同步阿里云镜像

1.下载阿里云镜像repo文件
项目使用CentOS6系统，因此我下载的文件是：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base - mirrors.aliyun.com
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
        http://mirrors.aliyuncs.com/centos/$releasever/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-6

#released updates 
[updates]

        http://mirrors.aliyuncs.com/centos/$releasever/updates/$basearch/

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras - mirrors.aliyun.com

baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
        http://mirrors.aliyuncs.com/centos/$releasever/extras/$basearch/

#additional packages that extend functionality of existing packages
[centosplus]

baseurl=http://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/
        http://mirrors.aliyuncs.com/centos/$releasever/centosplus/$basearch/

        http://mirrors.aliyuncs.com/centos/$releasever/contrib/$basearch/

gpgcheck=1

gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-6

2.刷新缓存

yum clean all
yum makecache

3.yum repolist

[root@localhost yum.repos.d]# yum repolist
已加载插件：fastestmirror, security
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
仓库标识仓库名称状态
baseCentOS-6 - Base - mirrors.aliyun.com6,706
extras  CentOS-6 - Extras - mirrors.aliyun.com 46
updates CentOS-6 - Updates - mirrors.aliyun.com   826
repolist: 7,778

4.同步镜像到本地

reposync -r base
reposync -r extras
reposync -r updates

5.创建YUM仓库

yum installcreaterepo yum-utils -y
cd base
createrepo ./
cd ../extras
createrepo ./
cd ../updates
createrepo ./

6.安装nginx，搭建本地Web服务器
内容省略…
贴上配置文件nginx.conf:

server {
    listen       80;
    server_name  localhost;
    root /yumrepo;
    #charset koi8-r;

    #access_log  logs/host.access.log  main;

    location / {
        autoindex on;
        autoindex_exact_size off;
        autoindex_localtime on;
    }

7.其他服务器连接YUM仓库：

vim /etc/yum.repos.d/test.repo

[base]
name=CentOS-Base(GDS)
baseurl=http://10.63.215.7/base
path=/
enabled=1
gpgcheck=0

[updates]
name=CentOS-Updates(GDS)
baseurl=http://10.63.215.7/updates
path=/
enabled=1
gpgcheck=0

[extras]
name=CentOS-Extras(GDS)
baseurl=http://10.63.215.7/extras
path=/
enabled=1
gpgcheck=0

8.完工！
上面的3个base，extras，updates下载到本地是11GB

下面附一个脚本：

#!/bin/bash
