# installing gitolite
### pre-requisites
If you managed to install git, you might already have what gitolite needs:
* git itself, the more recent the better
* perl, typically installed with git, since git sort of needs it; any
version that includes `Data::Dumper`[1] will do.
* one user account on the server, with password access [2]
A major objective is to allow use by people without root access, permissions
to create other userids, etc. Even if you have root, please add a user just
for gitolite and do all this from that user.
### getting a tar file from a clone
You can clone the repo from github, then execute a make command to extract a
tar file of the branch you want. Please use the make command, not a plain
"git archive". The comments in the `Makefile` will explain why.
git clone git://github.com/sitaramc/gitolite.git
cd gitolite
make master.tar
# or maybe "make rebel.tar" or "make pu.tar"
### quick install from tar file
* make a temp directory somewhere, cd to it, and unpack the tar file
* run `src/install.pl` and follow the prompts
**When you are told to edit some file, please read the comments in the file**.
And if you can make some time to read the documentation, please do.
Especially if you have problems.
Notes:
* At present the location of `~/.gitolite.rc` is fixed (maybe later I'll
change it to a "git config" variable but I don't see much need right now)
If you edit it and change any paths, be sure to keep the perl syntax --
you *don't* have to know perl to do so, it's fairly easy to guess in this
limited case. And of course, make sure you adjust the commands shown
above to suit the new locations
* the config file is (by default) at `~/.gitolite/conf/gitolite.conf`,
though you can change its location in the "rc" file. Edit the file as you
wish. The comments in the file ought to be clear enough but let me know
if not
* if you want to bring in existing (bare, server) repos into gitolite, this
should work (refer to `~/.gitolite.rc` for *your* values of the pathnames
below):
* backup the repo, then move it to `$BASE_REPO`
* copy `$GL_ADMINDIR/src/update-hook.pl` to
`[reponame].git/hooks/update` -- if you don't do this, per branch
restrictions will not work
* then update the keys and the config file and "compile" (see "admin"
document)
### Footnotes:
[1] Actually, due to the way gitolite is architected, you can manage
without `Data::Dumper` on the server if you have no choice. Only
`gl-compile-conf` needs it, so just run that on some other machine and copy
the two output files across. Cumbersome but doable... the advantage of
separating all the hard work into a manually-run piece :)
[2] If you have *only* pubkey access, and **no** password access, then your
pubkey is already in the server's `~/.ssh/authorized_keys`. If you also need
to access git as a developer (clone, push, etc), do *not* submit this same
pubkey to gitolite -- it won't work.
Instead, create a different keypair for your "developer" role (by, e.g.,
`ssh-keygen -t rsa -f ~/.ssh/gitdev`), then give `~/.ssh/gitdev.pub` to
gitolite as "yourname.pub", just like you would do for any other user.
Then you create a suitable `~/.ssh/config` to use the correct key
automatically, something like this:
host gitadm
hostname my.server
user my_userid_on_server
host gitdev
hostname my.server
user my_userid_on_server
identityfile ~/.ssh/gitdev
From now on, `ssh gitadm` will get you a command line on the server, to do
gitolite admin and other work. And your repository URLs would look like
`gitdev:reponame.git`. Very, very, simple...
And as with gitosis, there's more "ssh" magic than "git" magic here :-)
