  • Howto backup Subversion and move it to a new machine.
  • Back Up Your Data !
  • svnadmin dump repo and scp to other machine.
  • Do this for each repository you have.
svnadmin dump /path/to/reponame > /tmp/reponame.dump ; scp -rp /tmp/reponame.dump user@server.domain.com:/tmp/
  • On other machine install subversion
pacman -Sy subversion
  • Make sure you set svnserve in /etc/rc.conf
  • Edit the DAEMONS line so it starts on next boot.
DAEMONS=(syslog-ng hotplug !pcmcia network netfs crond sshd svnserve httpd)
  • Create the corrisponding repositories.
  • Do this for each repository you have.
svnadmin create /path/to/reponame
  • Load svn dump into new repo on new machine.
  • Do this for each repository you have.
svnadmin load /path/to/reponame < /tmp/repo1.dump
  • Setting Permissions.. CRUCIAL
  • This is the most common mistake when moving a svn repo.
  • Do this for each repository you have.
chown -R svn:svnusers /path/to/reponame ; chmod -R g+w /path/to/reponame/db/
  • Sample Permissions:
bash-2.05b# ls -l | grep svn
drwxrwxr-x   7 svn   svnusers      512 Apr 27 15:06 reponame1
drwxrwxr-x   7 svn   svnusers      512 Apr 27 15:06 reponame2
drwxrwxr-x   7 svn   svnusers      512 Apr 27 15:06 reponame3
bash-2.05b# ls -l reponame1/ | egrep -i "db"
drwxrwsr-x  2 svn  svnusers  512 Apr 27 15:07 db
bash-2.05b#
  • Ok these repos should be allset and ready to rock.. however using svn+ssh:// will not work..
  • Note: we have to have a wrapper written for svnserve..
  • PLEASE FOLLOW CLOSELY HERE
  • check your ENV like:
bash-2.05b# env | egrep "^PATH="
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:/root/bin
bash-2.05b#
  • check where the svnserve binary is located:
bash-2.05b# which svnserve
/usr/local/bin/svnserve
bash-2.05b#
  • ok our wrapper is going to have to fall in PATH prior to this location.. /sbin is a good place seeing its our 1st exec path on the system as root.
  • create wrapper:
touch /sbin/svnserve ; chmod 755 /sbin/svnserve 
  • now edit it to look like so:
bash-2.05b# cat /sbin/svnserve 
#!/bin/sh
# wrapper script for svnserve
umask 007
/usr/local/bin/svnserve -r /path/to "$@"
bash-2.05b#
  • NOTE: see the -r /path/to ?? well this is what makes use of the svn co svn+ssh://server.domain.com:/reponame ( SEE THIS :/reponame ).. this sets root PATH.
  • you do not need to do: :/path/to/reponame.... this is the big trick here folks.
  • Start svnserve with new wrapper script like so:
/sbin/svnserve -d  ( start daemon mode )
  • check it with ps:
bash-2.05b# ps auxww | grep svn
root   66668  0.0  0.1  3608 1868  ??  Is   12:25AM   0:00.00 /usr/local/bin/svnserve -r /path/to -d
bash-2.05b#
  • we can also check the perms for remote users like this:
cdowns:~ ~$ svn ls svn+ssh://server.domain.com:/reponame
++server.domain.com++
dev/
qa/
release/
cdowns:~ ~$
  • Thats it !
Thats it !
