How to re-install ImunifyAV(+) / Imunify360 from scratch?

Issue

Sometimes it might be necessary to re-install an ImunifyAV(+) or Imunify360 instance completely.

Environment

• ImunifyAV(+)
• Imunify360

Solution

To re-install ImunifyAV(+), execute:

wget https://repo.imunify360.cloudlinux.com/defence360/imav-deploy.sh -O imav-deploy.sh

bash imav-deploy.sh --uninstall

bash imav-deploy.sh

To re-install Imunify360, use the following:

wget https://repo.imunify360.cloudlinux.com/defence360/i360deploy.sh -O i360deploy.sh

bash i360deploy.sh --uninstall

bash i360deploy.sh

In case upon re-installation errors occur, like e. g.

[2025-02-03 08:01:14] [MIRROR] imunify360-firewall-cpanel-8.1.6-1.noarch.rpm: Status code: 404 for https://download.imunify360.com/el/8/slot-2/x86_64/imunify360-firewall-cpanel-8.1.6-1.noarch.rpm (IP: 2604:a880:400:d1::7cbc:d001)

please execute

yum clean all

yum makecache

or on Ubuntu:

apt remove --purge imunify*

or

dpkg --purge $(dpkg -l | awk '/imunify/ {print $2}')

apt-get autoremove --purge -y
rm -rf /var/imunify360 /etc/imunify360 /etc/sysconfig/imunify360 /var/lib/imunify* /opt/imunify360*

(also clean dpkg half-installed state)

dpkg --configure -a
apt-get -f install

(confirm there are no more leftovers)

systemctl list-unit-files | grep imunify

(if you see any dangling ones (e.g: imunify-agent-proxy.socket), remove them)

systemctl disable --now imunify-agent-proxy.socket
rm /etc/systemd/system/imunify-agent-proxy.socket
systemctl daemon-reload

and try again.
