Git pull from Bitbucket server

Question

I have a problem with running git pull from a php script on a remote server. I have looked at a lot of different sources to make it work but none works for me. So what have I done so far:

• Created the pub and private key for Apache:

  mkdir /var/www/.ssh
  sudo chown -R apache:nobody /var/www/.ssh
  su - apache -c "ssh-keygen -t rsa" 
  

• Then I have put my public key on Bitbucket.

• Then I run the command:

  sudo -u apache git pull 
  

Everything works fine.

After all that I wrote a simple sh script which I call from PHP.

1. The .sh script:

   #!/bin/sh
   git pull
   

2. and the PHP script:

   <?php    
   $cmd="./gitpullsc.sh 2>&1";
   echo exec($cmd);
   ?>
   

I run the php script from a web browser and I get back this:

Permission denied (publickey).
fatal: Could not read from remote repository.

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

Then I tried to add to the script whoami (to see if the user running the php script is the right one) and I get apache. So everything ok.

I use Red Hat linux.

Any help appreciated :)

UPDATE

Ok, maybe I found the problem, but still looking for the solution.

I run again the sudo -u apache git pull and now I am getting asked for the private key passphrase again.

But if I run the command ssh-add -l I get:

2048 ***thenumber** /var/www/.ssh/id_rsa (RSA)

So I think that everything is fine. But the problem maybe is that i run the ssh agent this way:

ssh-agent /bin/bash

---

UPDATE

Yes, the problem was really the passphrase prompt. I still don't know how to fix it, but for now I just left the passphrase blank and it works...

Answer 1

I answered a similar question. I really wanted to add a comment referring to that answer but I do not have enough points to add a comment.

The idea is use start ssh-agent once and load your keys to it. Later, in your .bashrc, you update environment variables so that it points to the same ssh-agent (that already has the keys).

Please look at trying to deploy using Capistrano but ssh-agent on my remote machine doesn't keep my identity loaded so the git command fails; why?
