通常同一個開發團隊會參與多個專案，在安裝時我們需要考慮支援多專案的管理。對於多專案的管理，我們可以這樣設計:
:arrow:每個Project一個專屬的Subverstion Repository，但是放在一個共同的根目錄下:
/path/to/repos/project1
/path/to/repos/project2
Repository存取方式:
http://my.domain.name/svn/project1
http://my.domain.name/svn/project2

:arrow:每個Project一個專屬的Trac Project Environment，但是放在一個共同的根目錄下:
/path/to/projects/project1
/path/to/projects/project2
Trac Project存取方式:
http://my.domain.name/projects/project1
http://my.domain.name/projects/project2

瞭解了設計的理念後，要安裝就很容易了，請將以下的程式碼複製後貼到一個trac_setup.sh檔案內，並修改相關的參數，然後將trac_setup.sh變更為可執行，然後執行即可(假設已安裝好gcc和[url=http://www.andowson.com/posts/list/177.page]PostgreSQL[/url])。

[/code]

至此便安裝好了Trac，由於改了Apache的設定檔，故我們需要重新啟動Apache
[code]service httpd restart[/code]

接下來要為每個專案建立一個Trac環境，Trac只需要安裝一套就可以支援多個專案，但是每個專案都要建立一個自己的Trac資料庫，例如我們的專案叫做project1，我們就新建一個叫trac_project1的資料庫（如果還有project2，資料庫名稱便取叫trac_project2）。請將下面的程式碼存成/var/lib/pgsql/newtracdb.sh並設為可執行：
[code=sql]psql -c "create user trac_$1 createdb;" template1
psql -c "create database trac_$1 with encoding 'unicode';" -U trac_$1 template1
psql -c "alter user trac_$1 nocreatedb;" template1
psql -c "alter user trac_$1 with encrypted password 'trac_$1';" template1[/code]

使用方式:
[code]su - postgres
./newtracdb.sh project1[/code]

建立好了資料庫，我們可以將下面的指令存檔為newproject.sh並設為可執行：

insert into session_attribute(sid, authenticated, name, value) values('user2', 1, 'name', 'Mary Doe');[/code]

將小組成員的資料加到這個新開好的專案
[code]su - postgres
psql trac_project1 trac_project1 -f session_attribute.sql[/code]

要加入小組成員的寫入權限時，可以請他先透過Trac網頁介面register，然後再把帳號加到svnaccess去; 或者透過htpasswd幫他開好帳號及密碼，然後再把帳號加到svnaccess去。

[code]htpasswd -b /var/trac/projects/.htpasswd user1 user1pwd

我实际的位置“/home/trac/projects/svnaccess”，经检查svnaccess文件内容无错误，其内容如下：
[/]
admin =rw

[project1:/]
* = r
admin = rw
user1 = rw
user2 =rw

使用psql –l后发现数据库已经存在了，按上述要求重建在执行上述删除和创建过程后，依然如故。

下面我介绍一下我的安装过程：
因为我安装的是RHEL5.0，没有REDHAT的安装好因此无法使用yum 命令从redhat 升级，因此我考虑使用安装光盘内的rpm 安装文件。
1、 在安装RRHEL5.0 时选择安装SUBVERSION、PostgreSQL、python-2.4.3
2、 从光盘中拷贝出mod_python-3.2.8-3.1.i386.rpm、libxml2-python-2.6.26-2.1.2.i386.rpm、mod_python-3.2.8-3.1.i386.rpm、swig-1.3.29-2.el5.i386.rpm、python-devel-2.4.3-19.el5.i386.rpm并用rpm –ivh 指令安装。
3、 安装后检查系统内的软件安装情况：

httpd Version : 2.2.3 Release : 6.el5
python Version : 2.4.3 Release : 19.el5
python-devel Version : 2.4.3 Release : 19.el5
mod_python Version : 3.2.8 Release : 3.1
subversion Version : 1.4.2 Release : 2.el5
mod_dav_svn Version : 1.4.2 Release : 2.el5
swig Version : 1.3.29 Release :2.el5

4、 从网络上下载的软件包如下：

clearsilver-0.10.5.tar.gz
docutils-snapshot.tgz
egenix-mx-base-3.0.0.linux-i686-py2.4_ucs4.prebuilt.zip
egenix-mx-base-3.1.0.linux-i686-py2.4_ucs4.prebuilt.zip
enscript-1.6.4.tar.gz
ez_setup.py
pyPgSQL-2.5.1.tar.gz
SilverCity-0.9.7.tar.gz
TracGantt-0.3.2a-py2.4.egg
Trac0.10.4zh3

5、 按照您文章中的顺序进行安装，区别在于第2点中的安装包是用rpm安装，不是您文中使用的yum 指令

6、 安装完trac_setup.sh中的软件后，再执行./newtracdb.sh project1（有点小问题，我在postgres下一条一条执行的，也创建了数据库和用户）， 再执行./newproject.sh project1 "My Project1" user1 并得到trac成功信息

至此，我觉得可以用http://localhost/svn/project1来查看源码，而结果就是上面的情况，用http://localhost/ projects /project1 来查看TRAC时出现Environment not found，

2.請問您有沒有執行trac_setup.sh的98-142行部分，可否檢視一下這幾個設定檔：
/etc/httpd/conf.d/python.conf
/etc/httpd/conf.d/subversion.conf

:arrow: 檢查/etc/httpd/conf.d/python.conf的檔尾有沒有下列設定：
[code]

</Location>
[/code]]]> http://www.andowson.com/posts/preList/20/427.page http://www.andowson.com/posts/preList/20/427.page GMT 我估计问题出在執行trac_setup.sh中的指令，因为我是用rpm包安装的，可能的原因有3个：
1、libxml2-python-2.6.26-2.1.2.i386.rpm这个包对不对，它是否是适合python-2.6的而不是python-2.4的。
2、subversion默认配置文件的位置不对，我用rpm -ql subversion 检查发现
/etc/subversion
/usr/bin/svn
usr/bin/svnadmin
......
其中subversion的配置文件在/etc/subversion中，而按照上面的安装过程配置文件应是在/etc/httpd/conf.d/subversion.conf
3、在您文中subversion安装应当是
yum -y install subversion mod_dav_svn swig，是在一行中完成的，而我安装是rpm -ivh swig-1.3.29-2.el5.i386.rpm,是分开安装的。

不知道是否是上述原因导致错误出现？]]> http://www.andowson.com/posts/preList/20/431.page http://www.andowson.com/posts/preList/20/431.page GMT
我有個建議就是可否請您將Trac整個移掉重裝，然後按照我這篇文章的預設路徑去裝裝看，先排除掉路徑問題，如果裝得起來您可再自行調整路徑重新安裝一次。]]> http://www.andowson.com/posts/preList/20/434.page http://www.andowson.com/posts/preList/20/434.page GMT 已解决，是因为SELinux的原因]]> http://www.andowson.com/posts/preList/20/452.page http://www.andowson.com/posts/preList/20/452.page GMT 在使用http://localhost/svn/project1访问时没有权限控制，也就是说任何人都可以访问代码。
因此我将/home/trac/projects/svnaccess中的内容进行修改：
[/]
admin = rw

[project1:/]
admin = rw
user1 = rw
user2 =rw

将其中的* = r 删除，之后用http://localhost/svn/project1访问就出现
Forbidden
You don't have permission to access /svn/project1 on this server.
而没有出现认证对话框，有什么办法可让其出现认证框以输入user passwd。

admin = rw
user1 = rw
user2 = rw
否則在Trac登入後按下[color=blue]Browse Source[/color]時會出現[color=red]Insufficient permissions to access /[/color]的錯誤。

如果要管控http://localhost/svn/project1時需要輸入帳號密碼，則可以修改/etc/httpd/conf.d/subversion.conf中的設定
[code]
<Location /svn>
DAV svn
SVNParentPath /home/andowson/repos
#<LimitExcept GET PROPFIND OPTIONS REPORT>
AuthType Basic
AuthName "Subversion repository"
AuthUserFile /home/andowson/projects/.htpasswd
AuthzSVNAccessFile /home/andowson/projects/svnaccess
Require valid-user
#</LimitExcept>
</Location>
[/code]
將原來的<LimitExcept>註解掉或刪除掉，再重新啟動Apache即可]]> http://www.andowson.com/posts/preList/20/462.page http://www.andowson.com/posts/preList/20/462.page GMT 在执行./newtracdb.sh project1时总是出现以下错误：
bash-3.1$ ./newtracdb.sh project1
" 不存在命错误: 数据库 "template1

user1登陆后能够浏览project2的所有代码，能够控制不让他浏览project2代码吗？]]> http://www.andowson.com/posts/preList/20/467.page http://www.andowson.com/posts/preList/20/467.page GMT [color=blue]user1只能看到project1的source code而user2只能看到project2的source code[/color]
是不可能的，因為：
1.如果我們將svnaccess最上面的[/]區塊刪除時，變成如下：
[project1:/]
admin = rw
user1 = rw
user2 =rw

[project2:/]
admin = rw
user2 =rw
配合修改/etc/httpd/conf.d/subversion.conf中的設定，此時我們可以控管由網頁去存取http://localhost/svn/project1時，需要輸入帳號密碼，此時用user1可以登入。接著將網址改成http://localhost/svn/project2，此時會再要求輸入帳號及密碼，但是不論嘗試多少次，用user1都不會成功。

2.此時再用user1登入Trac的project1然後去Browse Source時就會遇到Insufficient permissions to access /的錯誤。於是我們又將[/]區塊加回去svnaccess：
[/]
admin = rw
user1 = rw

[project1:/]
admin = rw
user1 = rw
user2 =rw

[project2:/]
admin = rw
user2 =rw
此時，可以正常瀏覽source code了，但是副作用就是此時用user1將可以登入http://localhost/svn/project2（可能user2還無法登入project2）
因此，可以推論，當有設定[/]時，Apache會採用[/]區塊的設定。
此外，此時用user1登入Trac project2也可以Browse Source，所以Trac也是用[/]這邊的設定。

所以這個問題在[color=red]一個[/color]svnaccess的狀況下是無解的。

那要怎麼做到原來的需求呢？
答案應該很明顯了，就是每個Trac project使用一個svnaccess檔案，我們可以在trac.ini裡面去設定這個檔案的路徑，例如：
[code][trac]
authz_file = /var/trac/projects/svnaccess_project1
[/code]
然後將原來的svnaccess的[/]區塊刪除，編輯svnaccess_project1如下：
admin = rw
user1 = rw
user2 =rw

最後是將Trac裡面BROWSER_VIEW從anonymous和authenticated刪除，用admin帳號登入Web介面去Admin->Permissions下執行即可，文字指令參考如下：
[code]trac-admin /var/trac/projects/project1 permission remove anonymous BROWSER_VIEW
trac-admin /var/trac/projects/project1 permission remove authenticated BROWSER_VIEW
[/code]

然後我們可以在右邊的Grant Permission:新增Subject:developer，Action: BROWSER_VIEW
然後再利用Add Subject to Group:將Subject: user1及user2陸續加到Group: developer

如此一來，我們可以確保只有加到每個Project的developer群組才能看到原始碼。

依此類推，完成project2的相關設定（trac.ini、svnaccess_project2及Permissions設定）

日後維護時，每個專案如有成員異動時，便得注意要同時修改svnaccess和svnaccess_projectX兩個檔案。]]> http://www.andowson.com/posts/preList/20/486.page http://www.andowson.com/posts/preList/20/486.page GMT http://trac-hacks.org/wiki/SvnAuthzAdminPlugin
[url=http://trac-hacks.org/changeset/latest/svnauthzadminplugin?old_path=/&filename=svnauthzadminplugin&format=zip]下載[/url]後，將其解壓縮，再執行下面的指令安裝
[code]python setup.py install[/code]
然後再修改trac.ini，將svnauthz.* = enabled加到[components]區塊下：如
[code][components]
svnauthz.* = enabled[/code]

在Trac中每個專案環境就是一個目錄，所以刪除專案很簡單，就是把對應的目錄刪除掉，然後對應的資料庫也刪除掉即可。

2.備份Trac專案：
可以使用trac-admin的hotcopy指令，
[code]$ trac-admin /path/to/projenv hotcopy /path/to/backupdir[/code]
例如：
[andowson@www ~]$ trac-admin /home/andowson/projects/webmail hotcopy /tmp/webmail
Hotcopying /home/andowson/projects/webmail to /tmp/webmail ... Hotcopy done.

檢視一下內容可以發現其實就是整個目錄複製過去而已，所以理論上只要先把Web Server停止後，自己使用OS的copy指令也是OK的
[andowson@www ~]$ ll /tmp/webmail/
總計 36

資料庫部分可以使用資料庫備份的指令，例如PostgreSQL的[url=http://twpug.net/docs/postgresql-doc-8.0-zh_TW/app-pgdump.html]pg_dump[/url]

3.還原Trac專案
也是很簡單，就是把備份的目錄覆蓋回去即可，先把Web Server停掉，然後把整個目錄結構copy回去，再把資料庫還原回去，然後再重起Web Server即可。

[b]Subverson的備份跟還原[/b]
1.備份Subversion的repository
[code]svnadmin hotcopy /path/to/reponame /path/to/backupdir[/code]
例如：
svnadmin hotcopy /home/andowson/repos/webmail /tmp/webmailrepo
這個指令單純的將repository的目錄複製一份出來

2.還原Subversion的repository
只要將先前用hotcopy備份的目錄複製回去即可
