Configuring the OS

After you create a VM, the OS has been installed, but you need to perform the following operations. The operations for configuring the OSs on the active and standby servers are the same.

Prerequisites

You have configured the mapping relationship between the haproxyIP and the FusionSphere OpenStack domain name on the local PC.

For the detail, you can refer to the Setting Mapping Relationship Between haproxyIP and FusionSphere OpenStack Domain Name in the Solution Documentation of FusionCloud NFVI.

To obtain the Solution Documentation:

  1. Log in to http://support.huawei.com.
  2. Enter the keyword FusionCloud NFVI xxx Solution Documentation in the search box and click Search.

    xxx: represents the FusionCloud NFVI version.

  3. Download the Solution Documentation document.

Procedure

The following steps are performed on the active server. When the steps are completed, you need to repeat them on the standby server.

  1. Log in to the ServiceCenter as a user whose role is the VDC administrator.

    1. Enter http://IP address of the ServiceCenter in a single-node system or floating IP address of ServiceCenter in a two-node cluster, and press Enter.
    2. Enter the user name and password, and click Login.

  2. Choose Resources > Computing > Compute Instances from the main menu.
  3. Select the VM created before and choose More > VNC Login in the Operation column.

    • Set different host names for the active and standby servers. For example, the active server name is eSightServer1 and the standby server name is eSightServer2.
    • The host name of the VM operating system must be the same as Cloud Host Name set during creating a VM.

    1. Click OK.

  6. Change the time and time zone of the operating system to be local ones.

    1. Use PuTTY to log in to the eSight server as the root user through the system IP address.
    2. Run the following command to change the number of operating system handles:

      # sed -i '/^[^#].*[[:space:]]\+nofile[[:space:]]\+/d' /etc/security/limits.conf

      # sed -i '$a\* - nofile 65535' /etc/security/limits.conf

    3. Run the following command to check whether the configuration is successful:

      # cat /etc/security/limits.conf | grep nofile

      If the following information is displayed, the configuration is successful:
