使用apt-mirror搭建debian鏡像源

debian官方提供了腳本ftpsync來搭建源鏡像，而 apt-mirror 是一個更簡單便捷的源鏡像搭建工具。

安裝 apt-mirror

sudo apt-get install apt-mirror

配置文件/etc/apt/mirror.list只要修改很少的地方，大部分使用默認值即可。

這里使用中科大鏡像 ftp.cn.debian.org 作為上游鏡像，只鏡像 debian jessie amd64 架構，不鏡像源代碼包。

############# config ################## # # set base_path /var/spool/apt-mirror # # set mirror_path $base_path/mirror # set skel_path $base_path/skel # set var_path $base_path/var # set cleanscript $var_path/clean.sh # set defaultarch 　# 默認架構與鏡像主機的架構一致,這里是amd64 # set postmirror_script $var_path/postmirror.sh # set run_postmirror 0 set nthreads 20 set _tilde 0 # ############# end config ############## deb http://ftp.cn.debian.org/debian jessie main contrib non-free deb http://ftp.cn.debian.org/debian/ jessie-backports main contrib non-free deb http://ftp.cn.debian.org/debian/ jessie-proposed-updates main contrib non-free deb http://ftp.cn.debian.org/debian/ jessie-updates main contrib non-free deb http://ftp.cn.debian.org/debian-security/ jessie/updates main contrib non-free #deb-src http://ftp.us.debian.org/debian unstable main contrib non-free # mirror additional architectures #deb-alpha http://ftp.us.debian.org/debian unstable main contrib non-free #deb-amd64 http://ftp.us.debian.org/debian unstable main contrib non-free #deb-armel http://ftp.us.debian.org/debian unstable main contrib non-free #deb-hppa http://ftp.us.debian.org/debian unstable main contrib non-free #deb-i386 http://ftp.us.debian.org/debian unstable main contrib non-free #deb-ia64 http://ftp.us.debian.org/debian unstable main contrib non-free #deb-m68k http://ftp.us.debian.org/debian unstable main contrib non-free #deb-mips http://ftp.us.debian.org/debian unstable main contrib non-free #deb-mipsel http://ftp.us.debian.org/debian unstable main contrib non-free #deb-powerpc http://ftp.us.debian.org/debian unstable main contrib non-free #deb-s390 http://ftp.us.debian.org/debian unstable main contrib non-free #deb-sparc http://ftp.us.debian.org/debian unstable main contrib non-free clean http://ftp.cn.debian.org/debian

開啟自動同步

只需 root 權限 cron 自動運行 apt-mirror 命令即可。

# vim /etc/cron.d/apt-mirror
0 0 * * * apt-mirror > /var/spool/apt-mirror/var/cron.log 2>&1

或者crontab -e

# m h  dom mon dow   command 0 0 * * * apt-mirror

發布鏡像服務

使用nginx發布源鏡像

將 apt-mirror 的鏡像目錄鏈接到/var/www/mirror

# ln -sf /var/spool/apt-mirror/mirror/ftp.cn.debian.org/ mirror

然后將nginx默認主機default(或者單獨虛擬主機)的根目錄設置為/var/www/mirror,並開啟目錄列表

root /var/www/mirror location / { autoindex on; }

其他機器就可以正常使用新建的源鏡像了。

 

 

另：

apt-mirror能夠將官方鏡像下載到本地，並保證目錄結構與其一致，但是不能對鏡像倉庫進行修改。如果想要修改鏡像倉庫，需要使用reprepro。

1、安裝apt-mirror

# aptitude update # aptitude install -y apt-mirror # dpkg -L apt-mirror /. /usr /usr/bin /usr/bin/apt-mirror /usr/share /usr/share/man /usr/share/man/man1 /usr/share/man/man1/apt-mirror.1.gz /usr/share/doc /usr/share/doc/apt-mirror /usr/share/doc/apt-mirror/changelog.gz /usr/share/doc/apt-mirror/changelog.Debian.gz /usr/share/doc/apt-mirror/copyright /etc /etc/cron.d /etc/cron.d/apt-mirror /etc/apt /etc/apt/mirror.list /var /var/spool /var/spool/apt-mirror /var/spool/apt-mirror/skel /var/spool/apt-mirror/mirror /var/spool/apt-mirror/var

2、修改配置文件，添加要下載的源（我這里添加的是debian_squeeze的源）

# vim /etc/apt/mirror.list set base_path /docker/debian_mirror set mirror_path $base_path/mirror set skel_path $base_path/skel set var_path $base_path/var set cleanscript $var_path/clean.sh set defaultarch <running host architecture> set postmirror_script $var_path/postmirror.sh set run_postmirror 0 set nthreads 40 set _tilde 0 deb-amd64 http://archive.debian.org/debian squeeze main deb-amd64 http://archive.debian.org/debian squeeze-lts main

3、手動運行apt-mirror下載鏡像

# apt-mirror Downloading 28 index files using 28 threads... Begin time: Mon Aug 21 11:24:11 2017 [28]... [27]... [26]... [25]... [24]... [23]... [22]... [21]... [20]... [19]... [18]... [17]...

End time: Mon Aug 21 21:38:48 2017 0 bytes in 0 files and 0 directories can be freed. Run /docker/debian_mirror/var/clean.sh for this purpose.

4、設置定時任務，定時與官方源同步

# vim /etc/cron.d/apt-mirror 0 0 * * * apt-mirror > /docker/mirror.log 2>&1

5、設置發布目錄軟鏈接

# ln -sv /docker/debian_mirror/mirror/archive.debian.org /docker/mirror

6、配置nginx發布鏡像目錄

# cd /usr/local/nginx/conf/vhosts/ # vim debian_mirror.conf server { listen 8081; server_name debian_mirror; root /docker/mirror location / { autoindex on; } access_log /usr/local/nginx/logs/debian_mirror.access.log oupeng_logs; error_log /usr/local/nginx/logs/debian_mirror.error.log; } # /usr/local/nginx/sbin/nginx -t # /usr/local/nginx/sbin/nginx -s reload

7、找一台debian6的機器添加本地源測試

# vim /etc/apt/sources.list deb http://117.119.33.138:8081/debian squeeze main deb http://117.119.33.138:8081/debian squeeze-lts main # aptitude update Hit http://117.119.33.138 squeeze Release.gpg Ign http://117.119.33.138/debian/ squeeze/main Translation-en Ign http://117.119.33.138/debian/ squeeze/main Translation-en_US Get:1 http://117.119.33.138 squeeze-lts Release.gpg [819 B] Ign http://117.119.33.138/debian/ squeeze-lts/main Translation-en Ign http://117.119.33.138/debian/ squeeze-lts/main Translation-en_US Hit http://117.119.33.138 squeeze Release Get:2 http://117.119.33.138 squeeze-lts Release [34.3 kB] Hit http://117.119.33.138 squeeze/main amd64 Packages E: Release file expired, ignoring http://117.119.33.138:8081/debian/dists/squeeze-lts/Release (invalid since 524d 12h 54min 42s)

其中第二個源squeeze-lts會提示過期，在apt配置文件中添加一項配置即可

# vim /etc/apt/apt.conf Acquire::Check-Valid-Until false; # aptitude update Get:1 http://apt.oupeng.com squeeze Release.gpg [1,655 B] Ign http://apt.oupeng.com/debian/ squeeze/main Translation-en Ign http://apt.oupeng.com/debian/ squeeze/main Translation-en_US Get:2 http://apt.oupeng.com squeeze-lts Release.gpg [819 B] Ign http://apt.oupeng.com/debian/ squeeze-lts/main Translation-en Ign http://apt.oupeng.com/debian/ squeeze-lts/main Translation-en_US Get:3 http://apt.oupeng.com squeeze Release [96.0 kB] Get:4 http://apt.oupeng.com squeeze-lts Release [34.3 kB] Get:5 http://apt.oupeng.com squeeze/main amd64 Packages [6,527 kB] Get:6 http://apt.oupeng.com squeeze-lts/main amd64 Packages [305 kB] Hit http://apt.puppetlabs.com squeeze Release.gpg Ign http://apt.puppetlabs.com/ squeeze/dependencies Translation-en Ign http://apt.puppetlabs.com/ squeeze/dependencies Translation-en_US Ign http://apt.puppetlabs.com/ squeeze/main Translation-en Ign http://apt.puppetlabs.com/ squeeze/main Translation-en_US Hit http://apt.puppetlabs.com squeeze Release Ign http://apt.puppetlabs.com squeeze/main Sources Ign http://apt.puppetlabs.com squeeze/dependencies Sources Ign http://apt.puppetlabs.com squeeze/main amd64 Packages Ign http://apt.puppetlabs.com squeeze/dependencies amd64 Packages Hit http://apt.puppetlabs.com squeeze/main Sources Hit http://apt.puppetlabs.com squeeze/dependencies Sources Hit http://apt.puppetlabs.com squeeze/main amd64 Packages Hit http://apt.puppetlabs.com squeeze/dependencies amd64 Packages Fetched 6,965 kB in 2s (3,148 kB/s) Current status: 43 updates [+41], 27994 new [+27654].
