ERROR: Repository not found whilst running git pull via shell_exec on php script

问题

I have set up ssh keys properly and added them to my github account . Whenever I ssh into the server and run git pull , everything runs normally and it pulls changes from the repository . However I have a deploy script that runs git pull via shell_exec() but it returns this error;

origin  git@github.com:sayopaul/autodeploy-tutorial.git (fetch)
origin  git@github.com:sayopaul/autodeploy-tutorial.git (push)
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

回答1:

PHP (the webserver) likely doesn't run as the same user you use when you SSH into the server. Thus, it doesn't have access/permission / doesn't use the correct SSH keys to authenticate vs GitHub.

I can think of 2 easy solutions:

Utilize sudo:

Add this rule in the sudo-conf (sudo visudo) to allow the user www-data to run (only) /usr/bin/git as yourotheruser:

www-data ALL=(yourotheruser) NOPASSWD: /usr/bin/git

Now you can invoke git using:

sudo -u yourotheruser git pull

Security advise: To limit the potential damage done if someone manages to execute arbitrary code through www-data:

Create a script owned by yourotheruser (and not writeable by others), e.g. /home/yourotheruser/deploy.sh with the contents:

cd /path/to/repo
git pull

And allow the sudo access only to this script. This way, no other git action than pull in the intended directory can be performed.

Change the user PHP itself is executed with:
- Use php-fpm
- Use the ITK MPM
