+
 
+
* Setting Permissions.. <b>CRUCIAL</b>
+
* This is the most common mistake when moving a svn repo.
+
* Do this for each repository you have.
+
<pre>
+
chown -R svn:svnusers /path/to/reponame ; chmod -R g+w /path/to/reponame/db/
+
</pre>
+
 
+
* Sample Permissions:
+
<pre>
+
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#
+
</pre>
+
+
* Ok these repos should be allset and ready to rock.. however using svn+ssh:// will not work..
+
* <b>Note</b>: we have to have a wrapper written for svnserve..
+
 
+
* <b>PLEASE FOLLOW CLOSELY HERE</b>
+
 
+
* check your ENV like:
+
<pre>
+
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#
+
</pre>
+
 
+
* check where the svnserve binary is located:
+
<pre>
+
bash-2.05b# which svnserve
+
/usr/local/bin/svnserve
+
bash-2.05b#
+
</pre>
+
 
+
* 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:
+
<pre>
+
touch /sbin/svnserve ; chmod 755 /sbin/svnserve
+
</pre>
+
 
+
* now edit it to look like so:
+
 
+
<pre>
+
bash-2.05b# cat /sbin/svnserve
+
#!/bin/sh
+
# wrapper script for svnserve
+
umask 007
+
/usr/local/bin/svnserve -r /path/to "$@"
+
bash-2.05b#
+
</pre>
+
 
+
* 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:
+
<pre>
+
/sbin/svnserve -d  ( start daemon mode )
+
</pre>
+
 
+
* check it with ps:
+
 
+
<pre>
+
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#
+
</pre>
+
 
+
* we can also check the perms for remote users like this:
+
 
+
<pre>
+
cdowns:~ ~$ svn ls svn+ssh://server.domain.com:/reponame
+
++server.domain.com++
+
dev/
+
qa/
+
release/
+
cdowns:~ ~$
+
</pre>
+
 
+
* Thats it !
+
<pre>
+
Thats it !
