Installing git on MyBook Live
This tutorial assume that you already have root ssh access to your MyBook Live.
What NOT to do
The fist time I wanted to install git I tryed using apt-get to install it. It worked, I got a functionnal git at the cost of the whole system not working anymore… The web interface stopped working, only the network shares where still working, but later I discovered that a reboot would brick the device!
I had to manually restore the hard drive.
HOWTO : git
Now that we know what not to do, how can we do it, safely ?
There is another source of softwares that we can use, it's Optware.
Follow the simple steps and you are ready to install git !
And now you can install git binaries:
/opt/bin/ipkg install git
To allow all the users to access it, you have tow choices, add the /opt/bin to your $PATH or link git in /usr/bin. I'll cover the second one :
ln -s /opt/bin/git /usr/bin/git
That's it, git should now work.
HOWTO : Gitolite
WIP - will complete this section soon. These instructions are currently a braindump, I will test and update this procedure soon.
Gitolite is a little trickier to install as the MyBook Live have some SELinux restrictions that prevent it's perl scripts from working properly… The restructions allow a user to create a file and add content (echo "write" > test.out), but not append to it (echo "append" » test.out), which is required for gitolite to work… This caused a lot of permission denied error that made little sense at first:
FATAL: errors found but logfile could not be created FATAL: /shares/git/.gitolite/logs/gitolite-2013-06.log: Permission denied FATAL: cli gitolite
Note : I need to find out how to fix the trustees instead of disabling them
With the web UI :
- Create a new user : git
- Create a new share : git
With ssh shell :
First, change the home directory of the git user in /etc/passwd to : /shares/git
Deactivate the SELinux trustees :
Prevent trustees to be restored at reboot. Edit the file /etc/init.d/mountDataVolume.sh and comment out the line :
Make sure our git user can connect with ssh:
Edit the file /etc/ssh/sshd_config, find the line with "AllowUsers" :
AllowUsers root git
And make sure this line is commented out :
#AcceptEnv LANG LC_*
Set your share permissions (required for ssh):
chmod o-w /shares/git chown git /shares/git
Log in your new git user:
su - git
Setup your environment:
mkdir ~/bin echo "export PATH=\$PATH:~/bin" > ~/.profile echo "export LANG=C" >> ~/.profile echo "umask 022" >> ~/.profile source .profile
Follow the gitolite install instructions
Once your setup is done you need to make sure your ssh permission are set :
chmod -R go-rw ~/.ssh
Have fun !
