同步阿里云镜像到本地，在本地搭建YUM仓库

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

additional packages that may be useful

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

additional packages that extend functionality of existing packages

[centosplus]
name=CentOS-$releasever - Plus - mirrors.aliyun.com
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/
http://mirrors.aliyuncs.com/centos/$releasever/centosplus/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-6

contrib - packages by Centos Users

[contrib]
name=CentOS-$releasever - Contrib - mirrors.aliyun.com
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos/$releasever/contrib/$basearch/
http://mirrors.aliyuncs.com/centos/$releasever/contrib/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib
gpgcheck=1
enabled=0
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
