= Trac 환경변수 =

Trac uses a directory structure and a database for storing project data. The directory is referred to as the Environment.

== Trac 저장소 만들기 ==

새로운 Trac 저장소는 [wiki:TracAdmin trac-admin] 명령어를 사용해서 만들어집니다.:
{{{
$ trac-admin /path/to/projectenv initenv
}}}

[wiki:TracAdmin trac-admin] will ask you for the name of the project, the
database connection string (explained below), and the type and path to
your source code repository.

''Note: The web server user will require file system write permission to 
the environment directory and all the files inside. Please remember to set
the appropriate permissions. The same applies to the Subversion repository 
Trac is eventually using, although Trac will only require read access as long 
as you're not using the BDB file system.''

== 데이타베이스 연결 스트링 ==

Since version 0.9, Trac supports both [http://sqlite.org/ SQLite],
[http://www.postgresql.org/ PostgreSQL] and [http://mysql.com/ MySQL] as
database backends.  The default is to use SQLite, which is probably sufficient
for most projects. The database file is then stored in the environment
directory, and can easily be [wiki:TracBackup backed up] together with the
rest of the environment.

임베디드 SQLite 데이타베이스에 대한 연결 스트링은:
{{{
sqlite:db/trac.db
}}}

If you want to use PostgreSQL or MySQL instead, you'll have to use a
different connection string. For example, to connect to a PostgreSQL
database on the same machine called `trac`, that allows access to the
user `johndoe` with the password `letmein`, use:
{{{
postgres://johndoe:letmein@localhost/trac
}}}

만약 PostgreSQL이 표준 포트(예를 들면 9342)가 아닌 포트에서 동작하고 있다면:
{{{
postgres://johndoe:letmein@localhost:9342/trac
}}}

`trac-admin initenv` 명령을 수행하기 전에 PostgreSQL를 사용해서 데이타베이스를 생성해야만 합니다.

And make sure PostgreSQl DB name is "trac". What worked for me:
And didn't work uppercase trac-user-name
{{{
sudo su - postgres -c createdb trac
sudo su - postgres -c psql trac
CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name';
}}}

(Just to remind you, if you don't have a sudo/su setup, you just need to do the createdb and psql statements. That threw me the first couple of times I read this.)

== Source Code Repository ==

You'll first have to provide the ''type'' of your repository (e.g. `svn` for Subversion,
which is the default), then the ''path'' where the repository is located.

If you don't want to use Trac with a source code repository, simply leave the ''path'' empty
(the ''type'' information doesn't matter, then).

For some systems, it is possible to specify not only the path to the repository,
but also a ''scope'' within the repository. Trac will then only show information
related to the files and changesets below that scope. The Subversion backend for
Trac supports this; for other types, check the corresponding plugin's documentation.

Example of a configuration for a Subversion repository:
{{{
[trac]
repository_type = svn
repository_dir = /path/to/your/repository
}}}

The configuration for a scoped Subversion repository would be:
{{{
[trac]
repository_type = svn
repository_dir = /path/to/your/repository/scope/within/repos
}}}

== 디렉토리 구조 ==

Trac 저장소 디렉토리는 일반적으로 다음의 파일과 디렉토리들로 구성되어 있습니다.:

 * `README` - 저장소에 대한 상세한 설명.
 * `VERSION` - 저장소의 버전 ID가 들어있는 파일.
 * `attachments` - 위키와 티켓의 첨부파일이 여기에 저장됩니다.
 * `conf`
   * `trac.ini` - 메인 환경설정 파일. [wiki:TracIni] 페이지를 참고하십시오.
 * `db`
   * `trac.db` - SQLite 데이타베이스 (SQLite를 사용하고 있다면).
 * `plugins` - 해당 Trac 저장소에 해당하는 [wiki:TracPlugins plugin]들 (Python eggs)
 * `templates` - 해당 저장소에 해당하는 템플릿트.
   * `site_css.cs` - 해당 저장소에 해당하는 CSS 규칙들.
   * `site_footer.cs` - 해당 저장소에 해당하는 page footer.
   * `site_header.cs` - 해당 저장소에 해당하는 page header.
 * `wiki-macros` - 해당 저장소에 해당하는 [wiki:WikiMacros 위키 매크로들].

  '''Note: don't confuse a Trac environment directory with the source code repository directory.
It happens that the above structure is loosely modelled after the Subversion repository directory 
structure, but they are not and ''must not'' be located at the same place.'''
