概述
說了centos的epel源搭建方式後，在說下ubuntu鏡像源及openstack本地源的搭建。
步驟
1.安裝apt-mirror
#apt-get install apt-mirror
2.手動建立/apt/ubuntu目錄，並修改/etc/apt/mirror.list，添加如下內容：
############# config ################## # # set base_path /var/spool/apt-mirror set base_path /apt/ubuntu # set mirror_path $base_path/mirror # set skel_path $base_path/skel # set var_path $base_path/var # set cleanscript $var_path/clean. # set defaultarch <running host architecture> # set postmirror_script $var_path/postmirror.sh set run_postmirror 0 set nthreads 20 set _tilde 0 deb http://mirrors.163.com/ubuntu/ trusty main restricted deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted deb http://mirrors.163.com/ubuntu/ trusty universe deb http://mirrors.163.com/ubuntu/ trusty-updates universe deb http://mirrors.163.com/ubuntu/ trusty multiverse deb http://mirrors.163.com/ubuntu/ trusty-updates multiverse deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse deb http://mirrors.163.com/ubuntu/ trusty-security main restricted deb http://mirrors.163.com/ubuntu/ trusty-security universe deb http://mirrors.163.com/ubuntu/ trusty-security multiverse deb http://extras.ubuntu.com/ubuntu trusty main clean http://mirrors.163.com/ubuntu/ deb http://ubuntu-cloud.archive.canonical.com/ubuntu trusty-updates/liberty main
3.執行apt-mirror ，開始下載和同步軟件包
#apt-miiror
4.安裝apache,並將本底源掛接到 apache的 WWW根目錄
#apt-miiror #apt-get install apache2 #cd /var/www/html/ #ln -s /apt/ubuntu/mirror/mirrors.163.com/ubuntu #ln -s /apt/ubuntu/mirror/ubuntu-cloud.archive.canonical.com/ubuntu openstack
確保能通過http://x.x.x.x/ubuntu 或 http://x.x.x.x/openstack能訪問目錄內容
5.通過計劃任務定期同步源
#Crontab -e 0 22 * * * /usr/bin/apt-mirror > /var/spool/apt-mirror/var/cron.log
6.配置客戶端源，編輯/etc/apt/source.list,刪除其他內容，加入：
deb http://10.0.0.100/ubuntu/ trusty main restricted deb http://10.0.0.100/ubuntu/ trusty-updates main restricted deb http://10.0.0.100/ubuntu/ trusty universe deb http://10.0.0.100/ubuntu/ trusty-updates universe deb http://10.0.0.100/ubuntu/ trusty multiverse deb http://10.0.0.100/ubuntu/ trusty-updates multiverse deb http://10.0.0.100/ubuntu/ trusty-backports main restricted universe multiverse deb http://10.0.0.100/ubuntu/ trusty-security main restricted deb http://10.0.0.100/ubuntu/ trusty-security universe deb http://10.0.0.100/ubuntu/ trusty-security multiverse deb http://10.0.0.100/openstack/ trusty-updates/liberty main
客戶端更新：
#apt-get update
