Zabbix appliance and installation CD versions are based on AlmaLinux 8 (x86\_64). Zabbix appliance installation CD can be used for instant deployment of Zabbix server (MySQL). ::: noteimportant You can use this appliance to evaluate Zabbix. The appliance is not intended for serious production use. ::: [comment]: # ({/eb965847-cfa1a361}) [comment]: # ({b72ced3b-cffa82a3}) ##### System requirements: - *RAM*: 1.5 GB - *Disk space*: at least 8 GB should be allocated for the virtual machine - *CPU*: 2 cores minimum Zabbix installation CD/DVD boot menu: ![](../../assets/en/manual/installation_cd_boot_menu1.png){width="600"} Zabbix appliance contains a Zabbix server (configured and running on MySQL) and a frontend. Zabbix virtual appliance is available in the following formats: - VMware (.vmx) - Open virtualization format (.ovf) - Microsoft Hyper-V 2012 (.vhdx) - Microsoft Hyper-V 2008 (.vhd) - KVM, Parallels, QEMU, USB stick, VirtualBox, Xen (.raw) - KVM, QEMU (.qcow2) To get started, boot the appliance and point a browser at the IP the appliance has received over DHCP. ::: noteimportant DHCP must be enabled on the host. ::: To get the IP address from inside the virtual machine run: ip addr show To access Zabbix frontend, go to **http://** (for access from the host's browser bridged mode should be enabled in the VM network settings). ::: notetip If the appliance fails to start up in Hyper-V, you may want to press `Ctrl+Alt+F2` to switch tty sessions. ::: [comment]: # ({/b72ced3b-cffa82a3}) [comment]: # ({84299878-589fd5e2}) #### Changes to AlmaLinux 8 configuration The appliance is based on AlmaLinux 8. There are some changes applied to the base AlmaLinux configuration.

[comment]: # ({/fffe0c21-589dc798}) [comment]: # ({3c315ab6-b2283a9a}) ##### Using a static IP address By default the appliance uses DHCP to obtain the IP address. To specify a static IP address: - Log in as root user; - Open */etc/sysconfig/network-scripts/ifcfg-eth0* file; - Replace *BOOTPROTO=dhcp* with *BOOTPROTO=none* - Add the following lines: - *IPADDR=* - *PREFIX=* - *GATEWAY=* - *DNS1=* - Run **systemctl restart network** command. Consult the official Red Hat [documentation](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/deployment_guide/s1-networkscripts-interfaces) if needed.

To change the time zone, copy the appropriate file from */usr/share/zoneinfo* to */etc/localtime*, for example: cp /usr/share/zoneinfo/Europe/Riga /etc/localtime [comment]: # ({/2f62f149-acf06935}) [comment]: # ({093d61cb-2c378c8d}) #### Zabbix configuration Zabbix appliance setup has the following passwords and configuration changes: [comment]: # ({/093d61cb-2c378c8d}) [comment]: # ({2cbef0f6-d39b5151}) ##### Credentials (login:password) System: - root:zabbix Zabbix frontend: - Admin:zabbix Database: - root: - zabbix: ::: noteclassic Database passwords are randomly generated during the installation process.
Root password is stored inside the /root/.my.cnf file. It is not required to input a password under the "root" account. ::: To change the database user password, changes have to be made in the following locations: - MySQL; - /etc/zabbix/zabbix\_server.conf; - /etc/zabbix/web/zabbix.conf.php. ::: noteclassic Separate users `zabbix_srv` and `zabbix_web` are defined for the server and the frontend respectively. ::: [comment]: # ({/2cbef0f6-d39b5151}) [comment]: # ({10e10c3a-f11ee379}) ##### File locations - Configuration files are located in **/etc/zabbix**. - Zabbix server, proxy and agent logfiles are located in **/var/log/zabbix**. - Zabbix frontend is located in **/usr/share/zabbix**. - Home directory for the user **zabbix** is **/var/lib/zabbix**.

For use in ESX, ESXi and vSphere they must be converted using [VMware vCenter Converter](https://support.broadcom.com/group/ecx/productfiles?subFamily=VMware%20vCenter%20converter&displayGroup=Standard&release=6.6.0&os=&servicePk=203348&language=EN) (authentication required for download). If you use VMWare vCenter Converter, you may encounter issues with the hybrid network adapter. In that case, you can try specifying the E1000 adapter during the conversion process. Alternatively, after the conversion is complete, you can delete the existing adapter and add an E1000 adapter.
