Automated Operating System Installation
Dedicated server customers have access to a list of available OS templates for automated installation. This list can be found in the server control panel in the Operating system dropdown menu under the Reinstall tab.
From here you can install the latest versions of popular Linux distros (Ubuntu LTS 16.04, Debian 8, Fedora 25) as well as Windows and VMWare EsXi (without active licenses).
There are also pre-installed software templates: Proxmox and Cloudera Hadoop.
Installing Windows has gotten even easier: if you previously had to send a request via ticket system and then wait, now Windows can be installed right from the control panel in just one click. The following versions are available: 2008 R2, 2012, 2012 R2. Licenses have to be ordered separately (available in the Services tab).
There are two installation options: active and inactive. The only difference is that active versions enable server access over winrm protocol for possible remote license activation. Nothing is added on top of the standard Windows image.
A lot of our users rent dedicated servers to build their own virtual environments. With these users in mind, we created a template with the Proxmox virtualization management system.
Proxmox is a Debian-based Linux distro and can be used to quickly deploy virtual machines and manage them over a web interface.
The autoinstall image uses open Proxmox VE (without support), which installs additional packages on top of Debian. If you need official support from Proxmox, then the repository needs to be changed in the signature. Added features include:
- LXC container support
- QEMU/KVM virtualization
- IPv6 support
- Ability to create high availability clusters with Proxmox VE HA Manager
VMware ESXi is the de facto standard for hypervisors in the world of virtualization. Almost any system can be used as a guest OS: Linux, Windows, FreeBSD, Solaris, etc.
VMware ESXi is only 348 MB, most of which are drivers for different operating systems (VMware Tools).
Of all the existing hypervisors, VMware ESXi is the most stable and secure. Its benefits include flexible access and security management, simple cluster deployment and configuration, uninterrupted virtual machine migration (vmotion technology), and more.
The VMware ESXi template will undoubtedly be of particular interest to those looking to configure a private cloud on a rented infrastructure. The latest releases of version 5 and 6 are available.
Only freely distributed hypervisors can be installed from our control panel. To deploy a full cluster of virtual machines, additional paid components will have to be installed. These will need to be purchased independently from VMware’s partners.
Cloudera Hadoop 5
For users looking to deploy a Hadoop cluster on servers rented from us, we’ve also prepared a special installation template built on Cloudera.
All of the servers to be included in the cluster must be connected over a local network. This can be done using our Local Port service.
Hadoop clusters consist of a master node (which Cloudera Manager has been installed on) and slave nodes (which are called simply agents in our panel).
We can define servers as master or slave in the control panel (under Reinstall - Operating System).
After you have entered all of the necessary parameters, click Reinstall.
Once the installation is complete, we recommend doing the following on each server:
- Configure the network interface of the local network
- Enter the appropriate local IP and hostnames in the /etc/hosts file for each server cluster
This can be done using Ansible or another configuration management tool.
Afterwards, we can start configuring the cluster in the Cloudera Manager web interface. In the browser, open http://[Cloudera Manager server IP]:7180/cmf/home. In the authorization form, enter the default login and password (admin, admin) and click Login.
A page with the licensing agreement will open. Check the box “Yes, I accept the End User License Terms and Conditions,” and then Continue.
Afterwards, choose which version of Cloudera Manager to install:
Choose the free version (Cloudera Express) and click Continue.
