Permissions with Git Post-Receive

  • Posted April 6, 2013

After following the Git tutorials, I have taken it a step further and created a ‘post-receive’ so that when I do a push to the live server it should then checkout to the virtual hosts directory of the website.

#!/bin/sh GIT_WORK_TREE=/var/www/domainname/public_html/ git checkout -f

However, when I try to do my push, it goes out the master successfully but I get permission denied errors when trying to create those files on my server web root.

e.g. remote: error: unable to create file index.php (Permission denied)

These errors actually make sense to me due to the way I have setup my server as per D.O.'s great how to articles. I disabled root access and created a new user that is added to the sudoers through visudo. Then setting up SSH keys for this user. I use this user for pushing out my git changes to the server.

The issue is, I believe, that this user that I connect to push doesn’t have the rights to write to the virtual hosts directory. All my files in these folders are owned by www-data (my nginx user) with the same group.

What is the solution? Create another user (SSH key) to connect with just for git that has higher permissions or is there a way to grant the post-receive sudo like abilities?

Apologies for the very long winded question but wanted to be absolutely clear with what I did.

You don’t have permission to write to the folder; right now, only the www-data user and the www-data group can. You might try adding yourself to the www-data group and making sure the group can write to the public_html folder, like so: <br> <br>$ sudo usermod -a -G www-data yourname <br>$ sudo chmod -R g+w /var/www/domainname/public_html <br> <br>Does that help?

I run a similar setup with GIT, which I’ll do my best to outline. <br> <br>I run gitolite and use a separate git user, in conjunction with two post-receive scripts. The first is a git deploy script (http://caton.liber.in/~ziber/git-deploy-hook.sh) and the second is a simple bash script to fix the permissions of ~git/public_html/ in conjunction with this script (which uses rsync to copy follows and isn’t terribly good at retaining file permissions): https://gist.github.com/JasonMKurtz/5390092 <br> <br>Hope this helps!
