From your description in the comments it seems that the problem is that your apache user cannot write to the repository, which is clearly required when you use git pull. You have two courses of action:
- Setup up Apache to run the script as another user (e.g. using suEXEC either on a VirtualHost or via userdir)
- Change the permissions on your repository so the
apache user can write to it
You should think carefully about the security implications of either choice, but the second option is probably easiest. If you don't already have such a group, you can create it with:
addgroup gitwriters
... and then add yourself and the Apache user to this group:
adduser [yourusername] gitwriters
adduser apache gitwriters
Then you can follow the instructions in another question to change the permissions on the repository. To reiterate those with some slight variations:
# Recursively, set the group ownership of every file and directory of your repository:
chgrp -R gitwriters /path/to/your/repo
# Recursively, make every file and directory of your repository readable and writable
# by the group:
chmod -R g+rw /path/to/your/repo
# Recursively, set the setgid of every directory in the repository. The setgid bit
# on directories means that files created in the directory will have the same group
# ownership as the directory.
find /path/to/your/repo -type d -print0 | xargs -0 chmod g+s
Then hopefully your git pull should work.
