Zabbix servers

• Create VM Zabbix EDU

./zabbix-edu/scripts/create_zabbix_vm_machines.sh 01 02 03

• Connect to VM Zabbix EDU and run scripts + reboot SELinux disable

gcloud compute ssh zbx01 --zone=europe-west1-c
sudo su -
./zabbix-edu/scripts/reconfigure_sshd.sh
reboot
./zabbix-edu/scripts/install_zabbix.sh
