Wordpress Error

I keep getting the same error, any ideas?

  1. I have generated a key without a password using ssh-keygen
  2. I set permissions on the keys to 600
  3. I have successfully logged in using ssh -i /root/.ssh/id_rsa 1**.**.*8.128
  4. I have tried changing hostname to localhost and

The server is running CentOS 5.4.


This is likely because your web server is not running as root and therefore doesn't have access to file's in /root/. Run ps on the host and grep for the server process name to see the username. It may well be something like nobody. If that's the case, I would suggest generating a key specifically for use by the web server and then chowning it to the user the server runs as. Hopefully this will solve your problem :)

  • The web server is running as apache, changing the chown ing the keys to this didn't work :( – rjstelling Sep 19 '10 at 11:52

Here is the full solution, thanks to michaelmior for his help, it got me half way.

  1. Run this command to generate keys: ssh-keygen

    You'll get this output:

    Generating public/private rsa key pair.
    Enter file in which to save the key (/home/user1/.ssh/id_rsa):
    Created directory ‘/home/user1/.ssh’.
    Enter passphrase (empty for no passphrase): (just hit enter, no need for a password)
    Enter same passphrase again: (same thing, hit enter again)
    Your identification has been saved in /home/user1/.ssh/id_rsa.
    Your public key has been saved in /home/user1/.ssh/id_rsa.pub.
    The key fingerprint is:
    xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx user1@server1.example.com
  2. Add the public key to your authorized_keys file

  3. Move the id_rsa and id_rsa.pub to /usr/local

  4. chown the files to the same user as your webserver (in my case apache)

  5. chmod the files to 600: chmod 600 id_rsa*

This should now work.

However, my installation kept hanging, a quick look at the httpd error_log file show me:

PHP Fatal error:  Allowed memory size of 33554432 bytes exhausted (tried to allocate 2966269 bytes) in /var/www/sites/....

Adding this code to the Wordpress wp-config.php file to temporally increase the amount of memory available:

define('WP_MEMORY_LIMIT', '64M');
