    目前subversion服务器可以用两种方式架设， 一种是基于svnserve，svnserve作为服务端； 一种是基于Apache，用apache作为服务端。

    下面说说这两种方式所用的配置文件。

    基于svnserve 配置文件位于版本库的conf下，有三个可以使用。

    1、svnserve.conf

        ### This file controls the configuration of the svnserve daemon, if you
        ### use it to allow access to this repository.  (If you only allow
        ### access through http: and/or file: URLs, then this file is
        ### irrelevant.)
        ### Visit [url]http://subversion.tigris.org/[/url] for more information.
        [general]
        ### These options control access to the repository for unauthenticated
        ### and authenticated users.  Valid values are "write", "read",
        ### and "none".  The sample settings below are the defaults.
        anon-access = none
        auth-access = write
        ### The password-db option controls the location of the password
        ### database file.  Unless you specify a path starting with a /,
        ### the file's location is relative to the conf directory.
        ### Uncomment the line below to use the default password file.
        password-db = passwd
        ### The authz-db option controls the location of the authorization
        ### rules for path-based access control.  Unless you specify a path
        ### starting with a /, the file's location is relative to the conf
        ### directory.  If you don't specify an authz-db, no path-based access
        ### control is done.
        ### Uncomment the line below to use the default authorization file.
        authz-db = authz
        ### This option specifies the authentication realm of the repository.
        ### If two repositories have the same authentication realm, they should
        ### have the same password database, and vice versa.  The default realm
        ### is repository's uuid.
        # realm = My First Repository

    2、passwd (svnserve.conf中指明的password-db文件)

    不同于基于apache的，此文件中的密码为明文

        ### This file is an example password file for svnserve.
        ### Its format is similar to that of svnserve.conf. As shown in the
        ### example below it contains one section labelled [users].
        ### The name and password for each user follow, one account per line.
        [users]
        # harry = harryssecret
        # sally = sallyssecret
 
    3、authz (svnserve.conf中指明的authz-db文件)

    此文件的写法有单库多库的区别，详情见http://bbs.iusesvn.com/thread-157-1-1.html

        ### This file is an example authorization file for svnserve.
        ### Its format is identical to that of mod_authz_svn authorization
        ### files.
        ### As shown below each section defines authorizations for the path and
        ### (optional) repository specified by the section name.
        ### The authorizations follow. An authorization line can refer to a
        ### single user, to a group of users defined in a special [groups]
        ### section, or to anyone using the '*' wildcard.  Each definition can
        ### grant read ('r') access, read-write ('rw') access, or no access
        ### ().
        [groups]
        # harry_and_sally = harry,sally
        # [/foo/bar]
        # harry = rw
        # * =
        # [repository:/baz/fuz]
        # @harry_and_sally = rw
        # * = r

    基于Apache

    配置文件可以在httpd.conf中指定，如

        <Location /svn>
        DAV svn
        #SVNListParentPath on
        SVNParentPath e:\svnreps
        AuthType Basic
        AuthName "Subversion"
        AuthUserFile e:\svnreps\passwd
        AuthzSVNAccessFile e:\svnreps\authz
        Require valid-user
        </Location>
 
    1、passwd (Location段中AuthUserFile指定)

    此文件由Apache的bin目录下htpasswd程序创建，密码为密文

        try1:$apr1$j04.....$k4XHO0EUJCuG2A5IveRYF1
        try2:$apr1$jR0.....$57ZHP2MRRAXQu4Dw.Rv.a1
 

    2、authz (Location段中AuthzSVNAccessFile指定)

    此文件格式跟基于svnserve方式的相同，同样也有单库多库区别，见http://bbs.iusesvn.com/thread-158-1-1.html

    [总结]

    从上面可以看出两种配置的区别，基于svnserve的配置文件一般均在conf目录下，目前还不能用绝对路径指定为其它目录，除非用相对路径；

    而基于 Apache的，配置文件由httpd.conf的Location段中指定，可以在任意位置。另外，两种用户密码文件的格式是不一样的，一种明文，一种密文。
