Log File Permissions

When the message "Log file /usr/local/zend/var/log/error.log does not exist or missing read permissions" appears it means that Zend Server does not have permissions to read the log file, or, the file does not exist. If the file does exist, you will need to provide the 'zend' user permissions to access the directory containing the file, and read the file itself.

To enable Zend Server to read error logs:

Open a terminal and switch to root using "su" or "sudo -s".
Run the following commands depending on the scenario:

Enterprise Linux 5/6 with Apache

chmod o+x /var/log/httpd

Enterprise Linux 5/6 / Debian / Ubuntu with Nginx

chmod o+r /var/log/nginx/{access,error}.log

Debian / Ubuntu with Apache2

chmod o+x /var/log/apache2

chmod o+r /var/log/apache2/{access,error}.log

SLES

chmod o+x /var/log/apache2

If this does not work, please refer to the Zend Support Center, at: http://www.zend.com/en/support-center
