I’m trying to send an image file from one server to another using rsync. The sending server’s public key has been placed into the receiving server’s /root/.ssh/authorized_keys . (I’ll not use root later on. Just trying to keep things as simple as possible for now.)
I can get an image copied successfully to the receiving server from the command line.
rsync -va /var/www/html/nameofimage.jpg root@111.222.333.444:/images/
However, I do not know how to write this into a PHP file. I thought this would work.
<?php
exec('rsync -va /var/www/html/nameofimage.jpg root@111.222.333.444:/images/');
?>
But when this file is invoked from the command line, I receive the message … rsync: link_stat “/home/myusername/ssh” failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1183) [sender=3.1.0]
Thanks for any direction with this.

Seems you are missing the identity file (private key), you have three methods to specify the identity file
Copy your key to
/var/www/.ssh/id_rsa (id.dsa or id_ecdsa)& chmod 0600 /var/www/.ssh/id_rsa. Then let ssh search for it.Specify it with -i option:
rsync -e "ssh -o StrictHostKeyChecking=no,UserKnownHostsFile=/dev/null -i /path/to/your/private/key" --other-options-here
- Specify in config file /var/www/.ssh/config (chown www-data & chmod 0600 may be required) Edit it with following content:
Host name_of_your_choice Hostname 45.55.136.175 Port 22 User your_user_name_at_remote_machine PreferredAuthentications publickey IdentityFile /path/to/your/private/key
