Nagios XI - Installing Latest SourceGuardian Loaders


This KB article explains how to install the latest SourceGuardian loaders that Nagios XI uses with PHP.



Establish a terminal session to your Nagios XI server as the root user and execute the following commands:

cd /tmp
rm -rf nagiosxi xi*
wget https://assets.nagios.com/downloads/nagiosxi/xi-latest.tar.gz
tar xzf xi-latest.tar.gz
cd nagiosxi


Once you've completed these steps you will need to restart the crond and httpd services:

RHEL 6 | CentOS 6 | Oracle Linux 6

service crond restart
service httpd restart


RHEL 7 | CentOS 7 | Oracle Linux 7

systemctl restart crond.service
systemctl restart httpd.service


Ubuntu 14

service cron restart
service apache2 restart


Debian | Ubuntu 16/18

systemctl restart cron.service
systemctl restart apache2.service


This completes the steps required to upgrade the SourceGuardian loaders.
