How to Install a Subversion Source Control Server on Ubuntu 10.

Step-by-Step Guide

1. 1

   Step 1: Install Ubuntu server.

   Visit http://www.ubuntu.com and download Ubuntu
   10.04 LTS server.
   
   Burn the downloaded ISO to CD and install on your spare PC.
   
   During the install select LAMP and OpenSSH. , sudo apt-get install subversion libapache2-svn , sudo svnadmin create /svn Alternately, if you want to store the subversion repository on another drive, you could enter something like /media/disk2/svn instead of /svn , sudo vim /etc/apache2/mods-enabled/dav_svn.conf Then paste the following and carefully replace all the elements starting YOUR_ with appropriate properties for your active directory. <location svn> DAV svn SVNPath /svn # Use LDAP auth against an active directory AuthName "Enter your domain username and password" AuthType Basic AuthBasicProvider ldap AuthLDAPBindDN "CN=YOUR_USER,OU=-- System Accounts,OU=YOUR_OU,DC=YOUR_DC,DC=YOUR_DC" AuthLDAPBindPassword "YOUR_PASSWORD" AuthLDAPURL "ldap://YOUR_DOMAIN_CONTROLLER:389/ou=YOUR_OU,dc=YOUR_DC,dc=YOUR_DC?samAccountName?" #require valid-user AuthLDAPGroupAttributeIsDN on require ldap-group CN=Software Development,OU=YOUR_OU,DC=YOUR_DC,DC=YOUR_DC </location>
   
   sudo a2enmod authnz_ldap , sudo addgroup svnusers sudo adduser administrator svnusers sudo adduser www-data svnusers sudo chgrp
   -R svnusers /svn sudo chmod
   -R g+w /svn , sudo /etc/init.d/apache2 restart , Browse to http://YOUR_SERVER/svn A successful install should prompt for your domain credentials and then show:- svn
   - Revision 0: / Powered by Subversion version
   1.6.6 (r40053)., sudo apt-get install trac libapache2-mod-python libapache2-mod-python-doc cd / sudo trac-admin trac initenv Answer the following questions:
   Project Name > YOUR_PROJECT Database connection string > <return></return> Repository type > <return></return> Path to repository > /svn , #require valid-user AuthLDAPGroupAttributeIsDN on require ldap-group CN=Software Development,OU=YOUR_OU,DC=YOUR_DC,DC=YOUR_DC </location>
   
   sudo chgrp
   -R svnusers /trac/ sudo chmod
   -R g+w /trac/ , trac-admin /trac permission add administrator TRAC_ADMIN ,, Browse to http://YOUR_SERVER/trac, enter your your domain username and password., See the related article at the bottom for how to mount a windows share on an Ubuntu server., This script will dump the entire repository to the backup location as a single dump file. sudo su (switch to root) mkdir /root/scripts && cd /root/scripts (make a directory for scripts and change to it) vi svn-full-backup.sh (edit the backup script and append the following) #! /bin/sh # Dump the entire svn repository to /tmp svnadmin dump /svn > /tmp/svn-full-backup.dump # Remove the previous backup rm
   -f /mnt/backup/svn-full-backup.dump # Copy the new backup file to the backup location cp /tmp/svn-full-backup.dump /mnt/backup/svn-full-backup.dump "Write and quit" (use :wq as described earlier) chmod +x svn-full-backup.sh (Make the script executable) ./svn-full-backup.sh (Initiate the backup operation) , This script will dump all revisions since the last incremental backup to another file.
   
   All files created specify the range of revisions that have been saved. vi svn-full-backup.sh (edit the incremental backup script and append the following) #!/usr/bin/perl use strict; use warnings; my $repo = '/svn'; my $local_dir = '/tmp'; my $savedir = '/mnt/backup/Incremental'; my $last_saved_file = $savedir.'/last_saved.txt'; # read the last saved revision from the file open(LAST_SAVED, '<'
   
   $last_saved_file); my $last_saved = <LAST_SAVED>; chomp $last_saved; close(LAST_SAVED); # get informed of the current last revision (head) my $head = `svnlook youngest $repo`; chomp $head; # of course, if the head is not younger than the last saved revision # it's useless to go on backuping if ($last_saved == $head) { exit(); } # if the last saved is 1000 and the head is 1023, we want the backup # from 1001 to 1023 my $from = $last_saved + 1; my $to = $head; # the backup filename looks like svn-01001_01023.svndump my $dumpfile = sprintf( '/svn-%05u_%05u.svndump'
   
   $from, $to ); my $local_dump_file = $local_dir.$dumpfile; my $command = sprintf( 'svnadmin dump
   -q
   -r%u:%u
   --incremental %s > %s'
   
   $from, $to, $repo, $local_dump_file ); system($command); if (grep /^Revision-number: $to/, `grep
   --text ^Revision-number: $local_dump_file`) { open(LAST_SAVED, '>'
   
   $last_saved_file); print LAST_SAVED $to, "\n"; close(LAST_SAVED); # here we compress the dump file system('gzip '.$local_dump_file); # let's add the md5sum of the file to MD5SUMS file storing md5sums of # all Subversion backups chdir($local_dir); use File::
   Basename; system('md5sum '.basename($local_dump_file).'.gz >> '.$savedir.'/MD5SUMS'); } my $mv_command = sprintf( 'mv %s %s'
   
   $local_dump_file.'.gz'
   
   $savedir.$dumpfile.'.gz' ); system($mv_command); "Write and quit" (:wq as above) chmod +x svn-inc-backup.sh (Make the script executable) ./svn-inc-backup.sh (Initiate the incremental backup operation) , Edit the cron table to schedule the two scripts to run.
   
   The incremental backup is run every night at 1 AM.
   
   The full backup is run on the 1st day of the month at 2 AM. crontab
   -e 0 1 * * * /root/scripts/svn-inc-backup.sh 0 2 1 * * /root/scripts/svn-full-backup.sh Exit the editor using CTRL-X , On another machine, perform the same subversion setup.
   
   Run the following command to import the dump file back into your empty repository. svnadmin load /svn < /mnt/backup/svn-full-backup.dump
