Administration Page Fails To Display – How to fix

Generally, in larger deployments of Log Server, PHP needs the memory_limit increased from the default of 128M. This usually fixes the issue.

We must keep in mind that this needs to be performed on all Log Server nodes.

The following steps will increase the value to 512M:

1. Firstly, establish a terminal session to each Log Server node as a root user.

This change needs to be made to our php.ini file, to determine the location of this file execute the following command:

find /etc -name php.ini

If there are multiple results, then the one in the apache directory is the one that needs changing.

2. Take a backup of the php.ini file.

3. We need to edit the file and make the following change:

memory_limit = 512M

Once the change has been made, we will have to restart Apache for the changes to take effect using one of the following commands:

RHEL 7+|CentOS 7+

systemctl restart httpd.service

Debian|Ubuntu 16/18/20

systemctl restart apache2.service

Once the service has restarted, the Administration page will be accessible.
