Gitolite administration instructions:

Installation:

• Create git user, configure its environment - including ${HOME}/bin

• As git user: git clone git://github.com/sitaramc/gitolite

• gitolite/install --to ${HOME}/bin

• Copy admin’s ssh key to system as ${user}.pub, then as git, execute: gitolite setup -pk ${key}

• From the host where the private key is:

  $ ssh git@wal1155 info
  hello dkoleary, this is git@walsinfmgmt1155 running gitolite3 v3.6.2-20-g78fc240 on git 1.7.1
  
   R W    gitolite-admin
   R W    testing
  

• Clone the gitolite-admin repo, then configure additional users/repos as needed.

Configuration:

• Clone the gitolite-admin repo:

  $ git clone git@wal1155:gitolite-admin ./wal1155-gitolite-admin
  Initialized empty Git repository in /ignite/dkoleary/mpi_git/wal1155-gitolite-admin/.git/
  remote: Counting objects: 6, done.
  remote: Compressing objects: 100% (4/4), done.
  remote: Total 6 (delta 0), reused 0 (delta 0)
  Receiving objects: 100% (6/6), done.
  

• Copy any/all required keys to keydir in the newly cloned local repo

  • cp nap1151-gitolite-admin/keydir/* wal1155-gitolite-admin/keydir

  • cd wal1155; git add -A && git commit -am'new keys'

  • git push

• If not doing mirroring, configure and/or migrate private/public repos as needed.

Mirroring:

• Uncomment/Update HOSTNAME parameter in ~git/.gitolite.rc file. HOSTNAME doesn’t have to be the host name but does have to be unique. Once done, compile.

  $ grep HOSTNAME .gitolite.rc | grep -v '#'
  HOSTNAME                  =>  "wal1155",
  $ gitolite compile
  

• Update ssh environment:

  • On new mirror, create a null passphrased default key:

    $ ssh-keygen -t dsa -P ""
    Generating public/private dsa key pair.
    Enter file in which to save the key (/home/git/.ssh/id_dsa):
    Your identification has been saved in /home/git/.ssh/id_dsa.
    Your public key has been saved in /home/git/.ssh/id_dsa.pub.
    [[snip]]
    

  • Copy newly created id_[rd]sa.pub to gitolite-admin repos in the keydir directory. Resulting filename should be server-${HOSTNAME} as defined aabove. Add/commit/push

  • Create ssh aliases using the hostnames as defined in ~git/.gitolite.rc:

    loglevel=error
    host nap1151
        hostname napsinfmgmt1151
        user git
        ForwardX11 no
    host nap1152
        hostname napsinfmgmt1152
        user git
        ForwardX11 no
    host wal1155
        hostname walsinfmgmt1155
        user git
        ForwardX11 no
    

  • Verify ssh ${gitsvr} info works from all hosts to all hosts.

    $ ssh nap1151 info
    hello server-wal1155, this is git@napsinfmgmt1151 running gitolite3 v3.6.2-4-g2471e18 on git 1.7.1
    
         C  private/CREATOR/..*
    

• Enable/configure mirroring:

  • On each node,

    • edit ~git/.gitlote.rc. Uncomment ‘Mirroring’ line on/about line 144.

    • Execute gitolite compile as the git user

  • In gitolite master (nap1151) repo, config directory, update mirroring to relfect the new system:

    cd ${mpigit}/nap1151-gitolite-admin/conf
    repo root/scripts
        RW+  = @admins
        RW+  = @san
        option mirror.master     = nap1151
        option mirror.slaves     = nap1152 wal1155
        option mirror.redirectOK = all
    git commit/push
    

  • In the new slave (wal1155 in this case) gitolite-admin repo, update the config to reflect mirroring:

    git clone git@wal1155:gitolite-admin ./wal1155-gitolite-admin
    cd wal1155-gitolite-admin/conf
    repo root/scripts
        RW+  = @admins
        RW+  = @san
        option mirror.master     = nap1151
        option mirror.slaves     = nap1152 wal1155
        option mirror.redirectOK = all
    git commit/push
    

  • Repull the newly mirrored gitolite-admin repo. If it’s not mirrored, log into git@nap1151 and execute:

    gitolite mirror push ${server} gitolite-admin
    

  • Push the other mirrored repos to the new slave. Access git@nap1151 then:

    cd .gitolite/conf
    for d in $(grep ^repo gitolite.conf | awk '{print $NF}' | \
        grep -vi private)
    do
        echo ${d}
        gitolite mirror push wal1155 ${d}
    done
