Command-line Configuration Method

The following sections will introduce the command line configuration method of HTTPS login to UI in two scenarios of single management node and multi-management node.
  • HTTPS mode is disabled by default.
  • After enabling HTTPS, the system supports port 5443 by default and you can specify other ports for login.
  • When HTTPS is enabled, if you log in to the Cloud on port 5000 using HTTP, the login page will be automatically redirected to HTTPS. Currently, only HTTP port 5000 is supported for automatic redirection to HTTPS.
  • The system supports PKCS12 format certificates by default. Currently, only PKCS12/JKS format certificate is supported. If you use certificates in other formats, please convert the format yourself.

Single Management Node Scenario

This section primarily focuses on scenarios involving a single management node and you will learn:
  • How to log in to the UI using the default HTTPS method
  • How to log in to the UI with a custom HTTPS configuration
  • How to switch back to HTTP for UI login

Log in to UI Using Default HTTPS Method

About this task

By default, the Cloud supports HTTPS login to the UI with a system default certificate.

Procedure

  1. Stop the management node service and UI service by running the following commands on the management node.
    zstack-ctl stop
  2. Make sure that the VNC console supports the HTTPS feature.
    1. Run the following command to view the certificate path and the private key password (which are both initially set to system default values).
      zstack-ctl show_ui_config
      Example:
      [root@localhost ~]# zstack-ctl show_ui_config
      db_url = jdbc:mysql://10.0.233.184:3306
      db_username = zstack_ui
      db_password = zstack.ui.password
      mn_host = 127.0.0.1
      mn_port = 8080
      webhook_host = 127.0.0.1
      webhook_port = 5000
      server_port = 5000
      log = /usr/local/zstack/apache-tomcat/logs
      enable_ssl = false
      ssl_keyalias = zstackui
      ssl_keystore = /usr/local/zstack/zstack-ui/ui.keystore.p12 //certificate path
      ssl_keystore_type = PKCS12
      ssl_keystore_password = password //private key password
    2. By default, the UI supports PKCS12 formatted certificates, whereas the VNC console proxy supports x509 formatted certificates. If you want to use the UI certificate for the VNC console proxy as well, you need to convert the PKCS12 formatted certificate into x509 format.
      openssl pkcs12 -in /path/to/mykeystore.p12 -out ui.keystore.pem -nodes

      In this command, /path/to/mykeystore.p12 is the PKCS12 formatted certificate and ui.keystore.pem is the converted x509 formatted certificate.

      Example:
      [root@localhost ~]# openssl pkcs12 -in /usr/local/zstack/zstack-ui/ui.keystore.p12 -out ui.keystore.pem -nodes
      Enter Import Password:
      MAC verified OK
    3. Edit the zstack.properties configuration file in /usr/local/zstack/apache-tomcat/webapps/zstack/WEB-INF/classes/zstack.properties, and set the certificate path to an absolute path (pointing to the certificate private key password file).
      consoleProxyCertFile = /usr/local/zstack/zstack-ui/ui.keystore.pem
  3. Run the following command to automatically generate a certificate based on the default configuration and log in to the UI using HTTPS with the default certificate. The default port is 5443.
    zstack-ctl config_ui --enable-ssl True
  4. Run the following command on the management node to enable the management node service and UI service.
    zstack-ctl start
  5. To access the ZStack Cloud management interface (https://your_domain_name:5443), use a Chrome or Firefox browser. Enter the default username and password (admin/password) to log in to the UI via HTTPS.
  6. Set the console proxy address.

    Log in to the UI interface, on the main menu of ZStack Cloud, choose Operational Management > Access Control > Console Proxy and set the console proxy as your_domain_name to make sure the console opens properly.

Log in to UI with Custom HTTPS Configuration

About this task

By default, the Cloud supports logging in to the UI using HTTPS with the custom certificate.

Procedure

  1. A custom certificate is required. You can generate a system self-signed certificate using related tools or purchase a certificate issued by a commercial CA.
    You can use Keytool (a Java data certificate management tool) to generate a self-signed certificate.
    mkdir certs
    
    keytool -genkey -alias tomcat  -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore ./certs/keystore.p12 -validity 365
    Example:
    [root@localhost ~]# mkdir certs
    [root@localhost ~]# keytool -genkey -alias tomcat  -storetype PKCS12 -keyalg RSA -keysize 2048 \
    -keystore ./certs/keystore.p12 -validity 365
    Enter keystore password:
    Re-enter new password:
    What is your first and last name?
      [Unknown]:  Jack Chen
    What is the name of your organizational unit?
      [Unknown]:  ZStack
    What is the name of your organization?
      [Unknown]:  DOC
    What is the name of your City or Locality?
      [Unknown]:  SH
    What is the name of your State or Province?
      [Unknown]:  SH
    What is the two-letter country code for this organizational unit?
      [Unknown]:  CN
    Is CN=Jack Chen, OU=Cloud, O=DOC, L=SH, ST=SH, C=CN correct?
      [No]:  Yes
    [root@localhost certs]# ls
    keystore.p12
  2. On the management node, run following command to stop the management node service and the UI service.
    zstack-ctl stop
  3. Ensure that the VNC console proxy supports HTTPS.
    1. The VNC console proxy supports x509 formatted certificates by default. You can convert the certificate format if needed.
      For example, you can convert a PKCS12 formatted certificate into x509 format.
      openssl pkcs12 -in /path/to/mykeystore.p12 -out ui.keystore.pem -nodes

      In this command, /path/to/mykeystore.p12 is the PKCS12 formatted certificate and ui.keystore.pem is the converted x509 formatted certificate.

      Example:
      [root@localhost ~]# openssl pkcs12 -in /root/certs/keystore.p12 -out ui.keystore.pem -nodes
      Enter Import Password:
      MAC verified OK
    2. Modify the zstack.properties configuration file. Set the certificate path to an absolute path (the absolute path points to the certificate private key password file).
      consoleProxyCertFile = /usr/local/zstack/zstack-ui/ui.keystore.pem
  4. Run following command to customize certificate alias, certificate path, certificate type, private key password, HTTPS login port, and other information. Then log in to the UI via HTTPS using the custom certificate.
    zstack-ctl config_ui --enable-ssl True \
    --ssl-keyalias=*** --ssl-keystore=*** --ssl-keystore-type=*** \
    --ssl-keystore-password=*** --server-port=*** --webhook-port=***
    //Record the custom parameter information in the zstack.ui.properties configuration file.
    //Including settings for: enabling HTTPS, certificate alias, certificate path, certificate type, private key password, HTTPS login port.
    
    zstack-ctl show_ui_config //View the custom parameter information
    
    zstack-ctl stop_ui
    zstack-ctl start_ui //Log in to the UI via HTTPS each time
    Example:
    [root@localhost ~]# zstack-ctl config_ui --enable-ssl True \
    --ssl-keyalias=tomcat --ssl-keystore=/root/certs/keystore.p12 --ssl-keystore-type=PKCS12 \
    --ssl-keystore-password=password --server-port=8888
    [root@localhost ~]# zstack-ctl show_ui_config
    db_url = jdbc:mysql://10.0.233.184:3306
    db_username = zstack_ui
    db_password = zstack.ui.password
    mn_host = 127.0.0.1
    mn_port = 8080
    webhook_host = 127.0.0.1
    webhook_port = 5000
    server_port = 8888
    log = /usr/local/zstack/apache-tomcat/logs
    enable_ssl = true
    ssl_keyalias = tomcat
    ssl_keystore = /usr/local/zstack/zstack-ui/ui.keystore.p12.cp
    ssl_keystore_type = PKCS12
    ssl_keystore_password = password
    [root@localhost ~]# zstack-ctl stop_ui
    successfully stopped the UI server
    [root@localhost ~]# zstack-ctl start_ui
    successfully started UI server on the local host, PID[32166], https://10.0.233.184:8888
  5. On the management node, run following command to start the management node service and the UI service.
    zstack-ctl start
  6. Enter the ZStack Cloud management interface (https://your_domain_name:your_server_port) using a Chrome or Firefox browser. Enter the default username and password (admin/password) to log in via custom HTTPS.
    Note:
    If you encounter issues with accessing VNC console using Firefox browser, follow these steps:
    1. Access https://your_domain_name:4900 using Firefox browser.
    2. Follow the prompts from the Firefox browser and add https://your_domain_name:4900 to the security exceptions.
    3. Open the VNC console using the Firefox browser.

    For more information, see Firefox.

  7. Set the console proxy address.

    Log in to the UI interface, on the main menu of ZStack Cloud, choose Operational Management > Access Control > Console Proxy and set the console proxy to your_domain_name to make sure the console opens properly.

Switch Back to HTTP for UI Login

Procedure

  1. Run the following command to restore the HTTPS related parameters in the zstack.ui.properties to the system default values.
    zstack-ctl config_ui --restore
  2. Run zstack-ctl stop_ui and zstack-ctl start_ui.
    Example:
    [root@localhost ~]# zstack-ctl config_ui --restore

Glossary

Instance

An instance is a virtual machine or server that runs the images of operating systems in Cloud, such as VM instance and elastic baremetal instance.

VM Instance

A VM instance is a virtual machine instance running on a host. A VM instance has its own IP address and can access public networks and run application services.

Volume

A volume provides storage space for a VM instance. Volumes are categorized into root volumes and data volumes.

Root Volume

A root volume provides support for the system operations of a VM instance.

Data Volume

A data volume provides extended storage space for a VM instance.

Image

An image is a template file used to create a VM instance or volume. Images are categorized into system images and volume images.

Instance Offering

An instance offering defines the number of vCPU cores, memory size, network bandwidth, and other configuration settings of VM instances.

Disk Offering

A disk offering defines the capacity and other configuration settings of volumes.

GPU Specification

A GPU specification defines the frame per second (FPS), video memory, resolution, and other configuration settings of a physical or virtual GPU. GPU specifications are categorized into physical GPU specifications and virtual GPU specifications.

vNUMA Configuration

vNUMA uses CPU pinning to passthrough the topology of associated host physical NUMA (pNUMA) nodes to a VM instance, generating a topology of virtual NUMA (vNUMA) nodes for the VM instance. This topology enables a vCPU on a vNUMA node to primarily access the local memory and thus improves VM performance.

NUMA (Non-Uniform Memory Access)

Non-uniform memory access (NUMA) is a computer memory design where the memory access time depends on the memory location relative to the CPU. Under NUMA, a processor can access its own local memory faster than non-local memory and thus improves VM performance.

pNUMA Node (physical NUMA Node)

A pNUMA node (physical NUMA node) is a host NUMA node predefined based on the host NUMA architecture. It is used to manage the CPUs and memory of the host.

pNUMA Topology (physical NUMA Topology)

A pNUMA topology (physical NUMA topology) is the topology of the host NUMA nodes predefined by the CPU vendor based on the host NUMA architecture.

vNUMA Node (virtual NUMA Node)

A vNUMA node (virtual NUMA node) is generated by passing-through associated pNUMA nodes via CPU pinning. It is used to manage the CPUs and memory of a VM instance.

vNUMA Topology (virtual NUMA Topology)

A vNUMA topology (virtual NUMA topology) is the topology of VM NUMA nodes generated by passing-through associated pNUMA nodes via CPU pinning.

Local Memory

Local memory is the memory that a CPU (pCPU or vCPU) accesses through the Uncore iMC (Integrated Memory Controller) of the same NUMA (pNUMA or vNUMA) node. Compared with accessing non-local memory, accessing local memory has lower latencies.

CPU Pinning

CPU pinning assigns the virtual CPUs (vCPUs) of a VM instance to specific physical CPUs (pCPUs) of the host, which improves VM performance.

EmulatorPin Configuration

EmulatorPin assigns all other threads than virtual CPU (vCPU) threads and IO threads of a VM instance to physical CPUs (pCPUs) of the host so that these threads run on assigned pCPUs.

Auto-Scaling Group

An auto-scaling group is a group of VM instances that are used for the same scenarios. An auto-scaling group can automatically scale out or in based on application workloads or health status of VM instances in the group.

Snapshot

A snapshot is a point-in-time capture of data status in a volume.

Affinity Group

A VM scheduling policy is a resource orchestration policy based on which VM instances are assigned hosts to achieve the high performance and high availability of businesses.

Zone

A zone is a logical group of resources such as clusters, L2 networks, and primary storage. Zone is the largest resource scope defined in the Cloud.

Cluster

A cluster is a logical group of hosts (compute nodes).

Host

A host provides compute, network, and storage resources for VM instances.

Primary Storage

A primary storage is one or more servers that store volume files of VM instances. These files include root volume snapshots, data volume snapshots, image caches, root volumes, and data volumes.

Image Storage

An image storage is a storage server that stores VM image templates, including ISO image files.

iSCSI Storage

iSCSI storage is an SAN storage that uses the iSCSI protocol for data transmission. You can add an iSCSI SAN block as a Shared Block primary storage or pass through the block to a VM instance.

FC Storage

FC storage is an SAN storage that uses the FC technology for data transmission. You can add an FC SAN block as a Shared Block primary storage or pass through the block to a VM instance.

NVMe Storage

A type of storage implemented via the NVMe-oF (NVMe over fabrics) protocol. You can add a block device configured from an NVMe storage as SharedBlock primary storage.

L2 Network

An L2 network is a layer 2 broadcast domain used for layer 2 isolation. Generally, L2 networks are identified by names of devices on the physical network.

VXLAN Pool

A VXLAN pool is a collection of VXLAN networks established based on VXLAN Tunnel Endpoints (VTEPs). The VNI of each VXLAN network in a VXLAN pool must be unique.

L3 Network

An L3 network includes IP ranges, gateway, DNS, and other network configurations that are used by VM instances.

Public Network

Generally, a public network is a logical network that is connected to the Internet. However, in an environment that has no access to the Internet, you can also create a public network.

Flat Network

A flat network is connected to the network where the host is located and has direct access to the Internet. VM instances in a flat network can access public networks by using elastic IP addresses.

VPC Network

A VPC network is a private network where VM instances can be created. A VM instance in a VPC network can access the Internet through a VPC vRouter.

Management Network

A management network is used to manage physical resources in the Cloud. For example, you can create a management network to manage access to hosts, primary storage, image storage, and VPC vRouters.

Flow Network

A flow network is a dedicated network for port mirror transmission. You can use a flow network to transmit the mirrors of data packets of NIC ports to the target ports.

VPC vRouter

A VPC vRouter is a dedicated VM instance that provides multiple network services.

VPC vRouter HA Group

A VPC vRouter HA group consists of two VPC vRouters. Either VPC vRouter can be a primary or secondary VPC vRouter for the group. If the primary VPC vRouter does not work as expected, the VPC vRouter becomes the secondary VPC vRouter in the group to ensure high availability of business.

vRouter Image
