# migrating from gitosis to gitolite
|
|
|
|
[TODO: make the migration tool fix up gitweb and daemon control also...]
|
|
|
|
Migrating from gitosis to gitolite is pretty easy, because the basic design is
|
|
the same. The differences are:
|
|
|
|
* gitolite does not use a special repo for the configuration, pubkeys, etc.
|
|
You can choose to version that directory but it is not required that you
|
|
do so
|
|
|
|
Here's how we migrated my work repos (note: substitute real paths, from your
|
|
`~/.gitolite.rc`, for `$REPO_BASE` and `$GL_ADMINDIR` below):
|
|
|
|
1. login as the `git` user on the server, and get a bash shell prompt
|
|
|
|
2. **disable gitosis** by renaming `/usr/bin/gitosis-serve` to something
|
|
else. This will prevent users from pushing anything while you do the
|
|
backup, migration, etc.
|
|
|
|
3. For added safety, **delete** the post-update hook that gitosis-admin
|
|
installed
|
|
|
|
rm $REPO_BASE/gitosis-admin.git/hooks/post-update
|
|
|
|
or at least rename it to `.sample` like all the other hooks hanging
|
|
around, or edit it and comment out the line that calls `gitosis-run-hook
|
|
post-update`.
|
|
|
|
If you do not do this, an accidental push to the gitosis-admin repo will
|
|
mess up your `~/.ssh/authorized_keys` file
|
|
|
|
4. take a **backup** of the `$REPO_BASE` directory
|
|
|
|
5. untar gitolite to some temporary directory and follow the instructions to
|
|
**install** it using `src/install.pl`
|
|
|
|
6. **convert** your gitosis config file:
|
|
|
|
cd $GL_ADMINDIR
|
|
src/conf-convert.pl < ~/.gitosis.conf > conf/gitolite.conf
|
|
|
|
be sure to check the file to make sure it converted correctly
|
|
|
|
7. **copy** the update hook to each of the existing repos (if you have repos
|
|
in subdirectories, this won't work as is; adapt it):
|
|
|
|
for i in $REPO_BASE/*.git
|
|
do
|
|
cp src/update-hook.pl $i/hooks/update
|
|
done
|
|
|
|
8. **copy** the keys from gitosis's keydir
|
|
|
|
cp $REPO_BASE/gitosis-admin.git/gitosis-export/keydir/* keydir
|
|
|
|
9. **Important: expand** any multi-key files you may have. See the "faq,
|
|
tips, etc" document in the doc directory for an explanation of what
|
|
multi-keys are, how gitosis does them and how gitolite does it
|
|
differently.
|
|
|
|
You can split the keys manually, or use the following code (just
|
|
copy-paste it into your xterm):
|
|
|
|
cd $GL_ADMINDIR
|
|
wc -l keydir/*.pub | grep -v total | grep -v -w 1 | while read a b
|
|
do
|
|
i=1
|
|
cat $b|while read l
|
|
do
|
|
echo "$l" > ${b%.pub}@$i.pub
|
|
(( i++ ))
|
|
done
|
|
mv $b $b.done
|
|
done
|
|
|
|
This will split each multi-key file (say "sitaram.pub") into individual
|
|
files called "sitaram@1.pub", "sitaram@2.pub", etc., and rename the
|
|
original to "sitaram.pub.done" so gitolite won't pick it up.
|
|
|
|
At this point you can rename the split parts more appropriately, like
|
|
"sitaram@laptop.pub" and "sitaram@desktop.pub" or whatever. *Please check
|
|
the files to make sure this worked properly*
|
|
|
|
10. **edit** `~/.ssh/authorized_keys` and **carefully** remove all the lines
|
|
containing "gitosis-serve", as well as the marker line that says
|
|
"auto-generated by gitosis, DO NOT REMOVE", then save the file. If the
|
|
file did not have any other keys and is now empty, don't worry -- save it
|
|
anyway because gitolite expects the file to be present (even if it is
|
|
empty).
|
|
|
|
At this point you're ready to "compile" the configuration. See the "admin"
|
|
document for what to do, and how to check the outputs, etc.
