Introduction

ZStack Cloud is built on Helix, a self-made virtualization kernel software that operates between the infrastructure layer and the upper-layer operating systems. It integrates essential components like hardware drivers, macro kernels, and virtual agents, shielding the differences among heterogeneous hardware. This releases operating systems from hardware driver dependencies, ensuring proper access to the heterogeneous hardware on the under layer. By doing so, Helix enhances hardware compatibility, high reliability, high availability, scalability, and performance of your virtual environment.

Currently, Helix has accommodated a variety of hardware, including Intel/AMD, Hygon, Kunpeng, FeiTeng, ShenWei, and Loongson. This makes it suitable for the finance, education, and government sectors, where controllability, stability, security, efficiency, and high performance are essential.

ZStack Cloud5.5.24 provides ISO of following versions based on Helix for the Cloud installation and deployment:
  • h84r: ZStack-Cloud-x86_64-DVD-5.5.24-h84r.iso

This document describes the installation process based on an h84r ISO.

图 1. Network Topology


This topic uses the following network planning as an example. Replace the sample information with your actual network information during deployment:

Node NIC Bond Bridge IP Address Gateway
MN1 eth0, eth1 bond0 br_bond0 192.168.195.200 192.168.0.1
MN2 eth0, eth1 bond0 br_bond0 192.168.196.125 192.168.0.1
VIP - - br_bond0 192.168.199.151 -
Node NIC Bond Bridge Description
MN1 em1, em2 bond1 - Used to carry the VM data network.
MN2 em1, em2 bond1 - Used to carry the VM data network.
Note:
  • The virtual IP address (VIP) is used to log in to the UI. Do not use the VIP to log in to a MN through SSH.
  • The gateway must be provided by a physical network device. Meanwhile, the gateway is used to detect the network status.
  • In production environments, we recommend that you use a management network bridge to carry the VIP, such as br_bond0.
  • If the MNs are also used as compute nodes, we recommend that you configure a dedicated VM data network.

Procedure

  1. Configure the management network of MN1.

    Log in to MN1 and run the following commands:

    [root@localhost ~]# zs-bond-lacp -c bond0
[root@localhost ~]# zs-nic-to-bond -a bond0 eth0
[root@localhost ~]# zs-nic-to-bond -a bond0 eth1
[root@localhost ~]# zs-network-setting -b bond0 192.168.195.200 255.255.0.0 192.168.0.1
[root@localhost ~]# zs-show-network
  2. Configure the management network of MN2.

    Log in to MN2, run the similar commands, and replace the IP address with the IP address of MN2:

[root@localhost ~]# zs-nic-to-bond -a bond0 eth1
[root@localhost ~]# zs-network-setting -b bond0 192.168.196.125 255.255.0.0 192.168.0.1
[root@localhost ~]# zs-show-network
  3. Configure the VM data network.

    If the MNs are also used as compute nodes, you can configure the VM data network on both MNs. On MN1, run the following commands as an example:

    [root@localhost ~]# zs-bond-lacp -c bond1
[root@localhost ~]# zs-nic-to-bond -a bond1 em1
[root@localhost ~]# zs-nic-to-bond -a bond1 em2
[root@localhost ~]# zs-show-network

    Log in to MN2, run the similar commands, and replace em1 and em2 with the actual NIC names.

    Note: After you attach NICs to a bond, you must configure LACP aggregation on the corresponding switch ports. Otherwise, the network communication might be abnormal.
  4. Check management network connectivity.

    After the network configuration is complete, complete the following checks:

    Check Item Requirement
    MN Connectivity The real IP addresses of the two MNs can ping each other.
    Gateway Connectivity Both MNs can ping the arbitration gateway.
    VIP Planning The VIP is not occupied by other devices, and is in a reachable network range with the real IP addresses of the two MNs and the gateway.
    Switch Configuration If link aggregation is used, LACP aggregation has been configured on the corresponding switch ports.
    Note:
    • The management network is used for MN communication and VIP carrying. The VM data network does not need to carry the VIP.
    • The preceding network planning is sample data. Replace the NIC names, IP addresses, netmask, and gateway based on your actual network environment.

Install HA Suite

After the operating system and network configuration are complete on both MNs, install the Multi-MN HA suite on one of the MNs to switch to a dual-MN HA environment.

Method Scenario Reference
Use the Command Line Applicable when there are only a few parameters and you want to complete the installation at one time. Use the Command Line

  • Name: Enter a name for the host.
  • Description: Optional. Enter a description for the host.
  • Type: Select a hypervisor type for the server. Valid values: KVM and XDragon.
  • Host IP: Enter the IP address of the host, for example, 172.20.14.32.
    • In the production environment, for stability and security concerns, we recommend that you separate the management network from the public network so that the management nodes and compute nodes reside in independent networks and have independent IP addresses.

      For example, if you use eth0 to connect a management network, ZStack Cloud uses the management network to communicate with compute nodes. If you use eth1 to connect to a public network, you can use the top aggregation switch to interconnect with the Internet.

    • The separation of the management network and public network can maximize system security and ensure sufficient bandwidth for the management network.
  • SSH Port: Enter an SSH port for the host. Default: 22. If you do not specify an SSH port for the host, the system uses port 22 as the SSH port.
  • User Name: Enter a username that has the sudo permission for the host.
    • If you specify a normal user, the user must have the sudo permission.
    • We recommend that you use the adduser command to create a normal user.
      The following script shows how to create a normal user and grant the user the sudo permission.
      #Create a normal user named test
[root@localhost ~]# adduser test
#Grant the user the sudo permission
[root@localhost ~]# echo "test    ALL=(ALL)    NOPASSWD: ALL" >>/etc/sudoers
  • Password: Enter the password of the user. Note the password is case sensitive.
Click Next, and ZStack Cloud will call the backend to configure the host.
  • The configuration process may last several minutes.
  • Error messages are prompted if errors occur.

What to do next

After completing the wizard, if you want to add more hosts to this cluster, make sure that the hosts to add are installed with the same system as the first host you add during the wizard, while the SSH ports, usernames, and the passwords can be the different. Note that ZStack Cloud supports not less than 256 LUNs on each host.
