Installing a Cluster

Installing a Cluster

Scenario

If the FusionInsight Configuration Planning Tool is unavailable, install the cluster manually. After Installing Manager is complete, configure the FusionInsight Manager installation wizard during the first running.

Impact on the System

During the cluster installation, the OS firewall of each node is automatically disabled by the installation script to ensure communication in the cluster. If the firewall needs to be enabled, see the FusionInsight HD 6.5.0 Communication Matrix to enable the ports manually.

NOTE:

For security, you are advised to disable the remote access permission of user root on each node after the cluster is installed.

Prerequisites

Installing Manager is complete.

The default SSH port No. (22) is used for each node in the cluster. Otherwise, the task in this section will fail.

Procedure

  1. Configure the browser. On Internet Explorer, click, choose Internet Options. In the displayed Internet Options dialog box, click the Advanced tab page.

    NOTE:

    On Google Chrome, click, choose Settings > Show advanced settings... > Network > Change proxy settings.... In the Internet Properties dialog box that is displayed, click the Advanced tab.

  2. In the Settings area, deselect Use SSL 2.0 and Use SSL 3.0, and select Use TLS 1.1, and Use TLS 1.2, as shown in Figure 7-2.

    Figure 7-2 Internet Options
    NOTE:

    If your browser is Internet Explorer 11, set the compatibility mode. Click and choose Compatibility View settings. In the displayed Compatibility View Settings dialog box, deselect Display intranet sites in Compatibility View and click Close.

  3. Log in to FusionInsight Manager.

    Enter the network address of FusionInsight Manager in the address box of the browser.

    The address format is http://WebService floating IP address of FusionInsight Manager system:8080/web.

    For example, enter http://192.168.10.110:8080/web.

    Enter your username (admin) and password (Admin@123).

    NOTE:
    • Clear the browser cache at first login.
    • If the certificate is not installed yet, a certificate error is displayed. Click Continue to this website.
    • The password needs to be changed at the first login.

      Default user password policies:

    • The password contains at least 8 characters.
    • The password must contain at least four types of the following: lowercase letters, uppercase letters, numerals, and special characters which can only be ~`!?,.:;-_'"(){}[]/<>@#$%^&*+|\=.
    • The password cannot be the same as the username or reverse username.
    • The password cannot be the same as the previous password.

  4. Create a cluster.

    Click Create Clusters. Enter the cluster name and set the safe mode, and then click Next.

    Description of the safe mode:

    • Security Mode, In a Security Mode cluster, Kerberos authentication is enabled for each component.
    • Normal Mode, In a Normal Mode cluster, Kerberos authentication is disabled for each component.
    NOTE:

    If you select the Normal Mode, user data can be accessed without security authentication, which brings security risks to enterprise services. It is not recommended that you select Normal Mode.

  5. Discover hosts. (The dual-plane networking scenario is used as an example.)

    1. Enter the IP address of the management plane of each node in the cluster in the IP Address or IP Address Segment dialog box by seeing Preparing Data.
      • Enter the management plane IP addresses of all nodes (including management nodes, control nodes, and data nodes).
      • Use commas (,) to separate IP addresses, for example, 192.168.10.10,192.168.10.11.
      • Use hyphens (-) to indicate an IP address segment if the IP addresses are consecutive, for example, 192.168.10.[10-20].
      • Use hyphens (-) to indicate an IP address segment if the IP addresses are consecutive, and use commas (,) to separate IP address segments, for example, 192.168.10.[10-20,30-40].
    2. Enter the password of user root (or user omm) that is used to access the server over SSH.
    3. Click Start Discovery to discover nodes on the server over SSH. Select all nodes and click Next to enter Set Rack.
      NOTE:

      Select all nodes (including management nodes, control nodes, and data nodes).

  6. Set the rack name.

    Select the host to be set, and click Set Rack. Base on the data planned in Preparing Data, set New Rack Name: in the Set Rack dialog box, such as /rack1/1.

    Click Next to go to Select Services.
    NOTE:

    According to reliability principles, it is recommended that the active and standby management nodes be deployed on different racks and the control nodes be deployed on different racks.

  7. Select the service roles.

    Based on the data planned in Installation Scheme, select the services to be installed. Click Next to go to Assign Role.

  8. Select the nodes where the service roles are installed.

    Based on the data planned in Installation Scheme, select the nodes where the service roles are installed. Click Next to go to Service Configuration.

  9. Set cluster parameters.

    Based on the data planned in Parameter Settings for the Cluster, select the services to be configured in the Service drop-down box, and set the parameters of each role, Click Next.

  10. Click Submit. In the displayed dialog box, determine whether to select Start the cluster after installation..

    • If yes, click OK to start the installation and start the cluster. After the cluster is installed and started, click Finish.
    • If no, go to Step 11.

  11. Click OK to install the cluster. After the cluster is installed, determine whether to start the cluster in the displayed dialog box.

    • If yes, click Yes to start the cluster. After the cluster is started, click Finish.
    • If no, click No to go to the FusionInsight Manager page. You can start the services manually.
    NOTE:

  12. Determine whether to install the cluster as user omm.

    • If yes, go to Step 13.
    • If no, no further action is required.

  13. Use PuTTY to log in to the active management node as user root.
  14. Run the sh /opt/preset/postset.sh command on all nodes.

    NOTE:

    The postset script is used to reclaim the cluster uninstallation permission of user omm.

    You can use the script tool in the software package to run a command or access a file on multiple nodes in a cluster. For details, see How to Run Commands or Access Files on Multiple Nodes in a Cluster.
