How To setup svn server on ubuntu

Create new SVN repo

svnadmin create wgrass

Import files to SVN repo

svn import /home/rashad/code/wgrass/ file:///home/rashad/svn/wgrass


Create User - newuser for svn repo

sudo htpasswd -cm /etc/apache2/pass.passwd newuser
Enter Password:
Re-Enter Password:

Add user to svn Repo

nano wgrass/conf/passwd

### 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]
newuser = pass

nano wgrass/conf/svnserve.conf

[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 directory containing
### this configuration file.
### If SASL is enabled (see below), this file will NOT be used.
### Uncomment the line below to use the default password file.
password-db = passwd

Setting up dav access
Allow Anonymous checkout

  DAV svn
  SVNPath /home/rashad/svn/wgrass
  AuthType Basic
  AuthName "wgrass"
  AuthUserFile /etc/apache2/pass.passwd
    Order deny,allow
    
      Require valid-user
    

Disable Anonymous checkout

  DAV svn
  SVNPath /home/rashad/svn/wgrass
  AuthType Basic
  AuthName "wgrass"
  AuthUserFile /etc/apache2/dav_svn.passwd
  Require valid-user

now you can access svn on yourhos.com/svn/wgrass
