(Optional) Installing the Operating System Patches

eSight periodically collects and releases SUSE Linux 12 SP2 patches to resolve security vulnerabilities disclosed by the SUSE Linux 12 SP2. If the SUSE Linux 12 SP2 patches are not installed, eSight functions are not affected. However, the SUSE Linux 12 SP2 security is affected. Therefore, you are advised to install the patch.

Prerequisites

  • The installation software has been prepared: patch installation package for the SUSE Linux 12 SP2.
  • The version of the SUSE Linux operating system is SUSE 12 SP2.

Procedure

  1. Use FileZilla to upload the patch package eSight_V300R009C00SPC200_SUSE12_SP2_Patch.zip to /opt on the server.
  2. Log in to the server as the root user. For details, see Logging In to the Server.

    Right-click on the desktop of the operating system and choose Open Terminal from the shortcut menu

  3. Decompress the patch package.

    # cd /opt

    # unzip eSight_V300R009C00SPC200_SUSE12_SP2_Patch.zip -d SUSE12_SP2_Patch

  4. Change the permission of the /opt/SUSE12_SP2_Patch directory.

    # chmod -R 775 /opt/SUSE12_SP2_Patch

  5. Install the patch.

    # cd /opt/SUSE12_SP2_Patch

    # bash rpms-update.sh

    If the message "rpms-update Successfully." is displayed, the patch is installed successfully.

  6. Restart the operating system.

    # sync;sync;sync;sync

    # shutdown -r now

  7. Delete the patch installation package and temporary files from the server after the patch is installed.

    # rm /opt/eSight_V300R009C00SPC200_SUSE12_SP2_Patch.zip

    # rm -rf /opt/SUSE12_SP2_Patch

Follow-up Procedure

After the patch is installed, check whether the operating system is running properly. If yes, perform the following operations to delete the old kernel information:

  1. Log in to the server as the root user.
  2. Obtain the kernel version information that is no longer used.
    1. Check and record the current kernel version used by the system.

      # uname -rp

      4.4.121-92.104.x86_64
    2. View and obtain the version information about all kernels in the current operating system.

      # rpm -qa | grep kernel*

      kernel-default-4.4.21-69.1.x86_64
      kernel-default-4.4.103-69.1.x86_64
      kernel-default-4.4.121-92.104.x86_64
      • After the operating system patch is installed successfully, the kernel version in 2.a must be the latest kernel version (with the largest version number). If the kernel version in 2.a is not the latest one, install the operating system patch again.
      • In the query result, the kernel that is not in use is the old kernel.
  3. Run the following command to delete old kernel versions of the operating system:

    # rpm -e kernel-default-4.4.21-69.1.x86_64

    kernel-default-4.4.21-69.1.x86_64: kernel name obtained in 2.b. If multiple kernel names exist, perform the operation multiple times.

  4. Run the following command to check the current kernel version of the operating system. The command output contains only information about the kernel that is in use.

    # rpm -qa | grep kernel*

    kernel-default-4.4.121-92.104.x86_64
