问题
I was trying the Perfect Workflow, with Git, GitHub, and SSH, and i have everything set up, except running the command git pull from php.
When i run exec('git pull') i get:
Could not create directory '/.ssh'. Host key verification failed. fatal: The remote end hung up unexpectedly
If i run it in the terminal (as root) it works just fine, but i need this hook to work from the Post-Receive URL (Github).
If i do exec('whoami') i get apache.
It's a (dv) from mediatemple with CentOS.

If you want apache (the user) to be able to pull from git, you'll have to create an ssh key for apache, then add that to the read only keys on github.
The flow is something like this (tweak to your needs)
usermod -s /bin/bash apache
su apache
cd ~
ssh-keygen # work through the keygen dance (added a dash)
Upload (tilde here refers to apache's homedir) ~/.ssh/id_rsa.pub to github and give apache access to whichever repos it needs to pull from.
Then you can test on the server by again su'ing to apache and running the git pull
su apache
cd ~/working-copy
git clone my-project
Once that's working you should be able to run a git pull through PHP.
