Editing Files

In this article you will be required to edit files. This documentation will use the vi text editor. When using the vi
editor:

  • To make changes press i on the keyboard first to enter insert mode
  • Press Esc to exit insert mode
  • When you have finished, save the changes in vi by typing :wq and press Enter

 

 

Resolution

In larger deployments of Log Server, PHP needs the memory_limit increased from the default of 128M. This needs to be performed on all Log Server nodes. The following steps will increase the value to 512M.

Establish a terminal session to each Log Server node as a root user.

This change needs to be made to your 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.

 

Edit the file and make the following change:

memory_limit = 512M

 

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

 

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. If the problem persists, please increase the value again.
