# Installation Instructions

1. Get your license key at https://www.imunify360.com/. You can purchase it or get a trial key from a received email.

2. Log in with root privileges to the server where Imunify360 should be installed.

3. Go to your home directory and run the commands:

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

where YOUR_KEY is your license key. Replace YOUR_KEY with the actual key - trial or purchased at https://www.imunify360.com/.

To install Imunify360 beta version add argument --beta . For example:

bash i360deploy.sh --key YOUR_KEY --beta

If you have an IP-based license, run the same script with no arguments:

bash i360deploy.sh

To view available options for installation script run:

bash i360deploy.sh -h

# Registering

In a case of registration key is passed later, then you can register an activation key via the Imunify360-agent command:

imunify360-agent register YOUR_KEY

Where YOUR_KEY is your activation key.

If you have IP-based license, you can use the following command:

imunify360-agent register IPL

# SELinux support

If SELinux (Security-Enhanced Linux) is enabled on your server, you should install the Imunify360 SELinux policy module. You can check SELinux status by sestatus command. Policy is shipped with Imunify360 package and is located in the /opt/imunify360/venv/share/imunify360/imunify360.te

To apply it, run the following commands:

checkmodule -M -m -o /var/imunify360/imunify360.mod /opt/imunify360/venv/share/imunify360/imunify360.te
semodule_package -o /var/imunify360/imunify360.pp -m /var/imunify360/imunify360.mod
semodule -i /var/imunify360/imunify360.pp

After that, restart imunify360 and imunify360-webshield services.

• For CentOS6/CloudLinux6:

service imunify360 restart
service imunify360-webshield restart

• For other systems:

systemctl restart imunify360
systemctl restart imunify360-webshield

If checkmodule command is not found, install it:

• For CentOS8/CloudLinux 8:

yum install policycoreutils-python-utils

# Troubleshooting

On DirectAdmin, Imunify UI requires the proc_open PHP function to be enabled. If you are unable to open the Imunify UI, you might see a related message in the web server error log. If so, remove it from the disable_functions list in php.ini.
