用 cvsup-mirror 架設 CVSup Server (mirror site)
如果你有多台電腦要做 cvsup 的動作，
可以先將一台電腦做 cvsup mirror
並啟動 cvsupd，直接提供其它 client 端 cvsup 的服務
而 client 端要更新時，只要設定連接到 cvsupd 這一台 server 的網路位置就可以了
注意！儲存容量最好能大於 5GB (甚至更多) 會比較妥當。
但，如果你 cvsup 更新 FreeBSD 的版本檔案都一樣的話，
那可能先用一台電腦去網路 cvsup 更新，再透過 nfs 來分享會比較省事
不過如果有需要更新多種版本的話 (例如：同時有 4.8、4.9、5.x ......的機器)
那自已建一台 mirro，或許會比較方便。
安裝 cvsup-mirror
$ cd /usr/ports/net/cvsup-mirror
$ make install |

===> Vulnerability check disabled
===> Extracting for cvsup-mirror-1.3
===> Patching for cvsup-mirror-1.3
===> Configuring for cvsup-mirror-1.3
I am going to ask you a few questions so that I can set up your
FreeBSD mirror configuration. Every question has a [default]
answer. To accept the default, just press ENTER.
At this point, I am just gathering information. I will not touch
your system until you type "make install".
Master site for your updates [cvsup-master.freebsd.org]? cvsup.tw.freebsd.org
How many hours between updates of your files [1]? 8
Now you must decide which sets of files you wish to make available
from your mirror site. You can choose any combination, and you
can put each set anywhere you want to on your disks. Although each
set is optional, we strongly encourage every mirror site to carry
at least the main source repository.
Do you wish to mirror the main source repository [y]? y
Where would you like to put it [/home/ncvs]? /FreeSpace/ncvs
Do you wish to mirror the installed World Wide Web data [y]? y
Where would you like to put it [/usr/local/www]? /FreeSpace/www
Do you wish to mirror the GNATS bug tracking database [y]? y
Note: the location for this must match "*/gnats", and
"gnats" must be a true subdirectory, not a symbolic link.
Where would you like to put it [/home/gnats]? /FreeSpace/gants
The location must match "*/gnats"
Where would you like to put it [/home/gnats]? /FreeSpace/gnats
Do you wish to mirror the mailing list archive [y]? y
Where would you like to put it [/home/mail]? /FreeSpace/mail
Now, a few questions so that I can set up your CVSup server properly.
For security reasons, both the CVSup client and server should run
under their own unique user and group IDs. These IDs should have no
special access privileges. Normally, the user:group "cvsupin:cvsupin"
is used for the client and "cvsup:cvsup" is used for the server, but
you can choose other names if you wish. At "make install" time, I
will create the users and groups, if they don't already exist.
Use unique user and group IDs for these. Do not use "nobody",
"nonroot", or "nogroup".
Unique unprivileged user ID for running the client [cvsupin]?
Unique unprivileged group ID for running the client [cvsupin]?
Unique unprivileged user ID for running the server [cvsup]?
Unique unprivileged group ID for running the server [cvsup]?
The CVSup server does its logging via syslog. At "make install"
time, I will set up the logging for you, if necessary. I will use
the "!program" feature of syslog to keep your CVSup log messages
separate from the messages of your other daemons.
Syslog facility for the server log [daemon]?
You can control the load on your machine by limiting the number of
clients that the CVSup server will serve at once. CVSup won't load
your network especially heavily, but it is more CPU and disk
intensive than most other file server software.
Maximum simultaneous client connections [8]? 4
Building the "config.sh" file ... Done.
Building the "cvsupd.access" file ... Done.

Installing files
You need a group "cvsup".
Would you like me to create it [y]? y
Done.
You need a user "cvsup".
Would you like me to create it [y]? y
Done.
You need a group "cvsupin".
Would you like me to create it [y]? y
Done.
You need a user "cvsupin".
Would you like me to create it [y]? y
Done.
Would you like me to create cvsupin's home directory (/home/cvsupin) [y]? /FreeSpace/cvsupin
Fixing ownerships and modes in "/usr/local/etc/cvsup".
Setting up links and directories for distributions.
Linking distrib.self -> ..
Linking FreeBSD.cvs -> /FreeSpace/ncvs
Fixing ownerships and modes in /FreeSpace/ncvs ... done.
Linking FreeBSD-www.current -> /FreeSpace/www
Fixing ownerships and modes in /FreeSpace/www ... done.
Linking FreeBSD-gnats.current -> /FreeSpace
Fixing ownerships and modes in /FreeSpace/gnats ... done.
Linking FreeBSD-mail.current -> /FreeSpace/mail
Fixing ownerships and modes in /FreeSpace/mail ... done.
Would you like me to set up the syslog logging [y]? y
Setting up server logging in "/etc/syslog.conf".
Creating "/var/log/cvsupd.log".
Giving syslogd a kick in the pants.
Adding cvsupd log entry to "/etc/newsyslog.conf".
Done.
Would you like me to set up your crontab for updates every 8 hours [y]? y
Scheduling updates every 8 hours in "/etc/crontab".
Done. The first update will be 5 minutes from now, at 15:48.
The cvsupd server will be started automatically after the first update,
and whenever you reboot.
You are now a FreeBSD mirror site.
===> Registering installation for cvsup-mirror-1.3 |
我們會發現在 /etc/crontab 中被加入了一筆
48 7-23/8 * * * root /usr/local/etc/cvsup/update.sh
這代表在 7-23 的 48 分，間每隔 8 小時會自動執行一次 /usr/local/etc/cvsup/update.sh
來 mirror 資料
要注意的是，初次 mirror 之後，所佔用的空間就有 4.1 GB 以上
所以在安裝時所指定的路徑，容量最好能大於 5GB (甚至更多) 會比較妥當。
提供 cvsup 服務 & 更新 ports-tree、src-tree
========================================
A 電腦 (ip: 192.168.1.68) <== Local 的 CVSup Server
啟動 cvsupd (可開機啟動)
| $ /usr/local/etc/rc.d/cvsupd.sh start |
B 電腦 (ip: 192.168.1.100) <== CVSup Client
新增一個 cvsup 的設定檔 (這裏是 ports 跟 src 合併的設定檔)
註：設定檔可參考 /usr/share/examples/cvsup/ 內的檔案
| 代碼: |
*default host=192.168.1.68
*default base=/usr
*default prefix=/usr
*default release=cvs tag=RELENG_4
*default delete use-rel-suffix
*default compress
src-all
ports-all tag=. |
註：這是 ports 及 stable 的 src
當然你可以把 ports 跟 src 的設定檔分開
| 代碼: |
*default host=192.168.1.68
*default base=/usr
*default prefix=/usr
*default release=cvs tag=.
*default delete use-rel-suffix
*default compress
ports-all |
| $ vi lan_cvsup_src_stable |
這是 stable 的寫法
| 代碼: |
*default host=192.168.1.68
*default base=/usr
*default prefix=/usr
*default release=cvs tag=RELENG_4
*default delete use-rel-suffix
*default compress
src-all |
| $ vi lan_cvsup_src_standard |
這是 standard 的寫法
| 代碼: |
*default host=192.168.1.68
*default base=/usr
*default prefix=/usr
*default release=cvs tag=.
*default delete use-rel-suffix
*default compress
src-all |
同時更新 ports-tree 及 src-tree
| $ cvsup -g -L 2 lan_cvsup |
此時 B 電腦就直接從 A 電腦取得 cvsup 的清單囉
如果你後來發現有其它的 cvsup server 跟你 cvsup mirror 連線速度較快
可以去修改 A 電腦的 /usr/local/etc/cvsup/config.sh
其中的
| 代碼: |
| host="cvsup.tw.freebsd.org" |
換成速度較快的外部 cvsup server 就行了 |
