I wanted to increase my servers upload_max_filesize, so I downloaded the PHP.ini file from /etc/ made the change locally and then uploaded the file via FTP.
During the upload the FileZilla mentioned that I was overriding the file on the server with my local copy, the difference in filesize was significant (which it shouldn't have been), something in the region of 67kb > 25kb.
After the upload, I've completely lost control of the installation. For instance the following command:
sudo chown -R ec2-user /ect/
Resulted in the following:
sudo: /etc/sudo.conf is owned by uid 500, should be 0
sudo: /etc/sudoers is owned by uid 500, should be 0
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
I'm not sure what I've done. I've clearly overridden the wrong file. Maybe I override a shortcut or a file in a shortcut.
Any suggestions on how to recover the mystery file?
