INSTALLING AND CONFIGURING RED HAT STORAGE CONSOLE ON HOST SYSTEM This chapter covers installing Red Hat Storage Console on the Red Hat Enterprise Linux 7.2 host system using packages and QCOW image format. 3.1. RED HAT STORAGE CONSOLE PACKAGE INSTALLATION To install Red Hat Storage Console, register the host system using Red Hat Subscription Manager, enable the required repositories, install the Red Hat Storage Console packages and start the server. The following procedure outlines the steps to install Red Hat Storage Console on the Host system: Procedure. Installing Red Hat Storage Console on Host System 1. To register the host system using Red Hat Subscription Manager, run the following command and enter the Red Hat Customer Portal username and password: # subscription-manager register 2. Attach the Entitlement Pools to the host system by running the following command: # subscription-manager attach --pool=[POOLID] Note The Pool ID depends on the registered Red Hat Customer Portal account. The available pools are accessible by running the subscription-manager list --available command. 3. Run the following command to disable any existing repositories: # subscription-manager repos --disable "*" 4. To enable the repositories required to install Red Hat Storage Console, run the following command: # subscription-manager repos --enable=rhel-7-server-rpms 5. Add the Red Hat Storage Console repository to the host system: # subscription-manager repos --enable=rhel-7-server-rhscon-2- main-rpms 6. Add the Ceph installer repository to the host system: # subscription-manager repos --enable=rhel-7-server-rhscon-2- installer-rpms 7. Import the GPG key by running the following command: 6 CHAPTER 3. INSTALLING AND CONFIGURING RED HAT STORAGE CONSOLE ON HOST SYSTEM # rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release 8. Install the Red Hat Storage Console packages: # yum install rhscon-core rhscon-ceph rhscon-ui After the Red Hat Storage Console Packages are successfully installed, the next step is to configure the Firewall. 3.2. FIREWALL CONFIGURATION 3.2.1. Configuring Red Hat Storage Console Server Ports Configure the firewall after the package installation of Red Hat Storage Console. The commands given in this section are to configure the firewall permanently. For the system to consider this, reload the firewall service by using the command firewall-cmd --reload, after executing all the port opening commands. For Skyring Service With Https and without Https: # firewall-cmd --permanent --zone=public --add-port=10443/tcp # firewall-cmd --permanent --zone=public --add-port=8080/tcp For Salt-Master Service # firewall-cmd --permanent --zone=public --add-port=4505-4506/tcp For Graphite-Web Access # firewall-cmd --permanent --zone=public --add-port=10080/tcp Data To Graphite Server # firewall-cmd --permanent --zone=public --add-port=2003/tcp Ceph Installer # firewall-cmd --permanent --zone=public --add-service=ceph-installer Note To configure the firewall for ceph-installer, ensure that the ceph-installer package is installed.

It can be used in multiple scenarios. To get more details about it, refer to the Book “Virtualization Guide” and in particular, to the following sections: Book “Virtualization Guide”, Chapter 1 “Virtualization Technology”, Section 1.2 “Virtualization Capabilities” Book “Virtualization Guide”, Chapter 1 “Virtualization Technology”, Section 1.3 “Virtualization Benefits” This best practice guide will provide advice for making the right choice in your environment. It will recommend or discourage the usage of options depending on your workload. Fixing conguration issues and performing tuning tasks will increase the performance of VM Guest's near to bare metal. 2 Before You Apply Modifications 2.1 Back Up First Changing the conguration of the VM Guest or the VM Host Server can lead to data loss or an unstable state. It is really important that you do backups of les, data, images, etc. before making any changes. Without backups you cannot restore the original state after a data loss or a misconguration. Do not perform tests or experiments on production systems.

  • A High-Performance Virtual Machine Filesystem Monitor in Cloud-Assisted Cognitive Iot
    A high-performance virtual machine filesystem monitor in cloud-assisted cognitive IoT Dongyang Zhana, Lin Yea , Hongli Zhanga, Binxing Fanga,b, Huhua Lia, Yang Liua, Xiaojiang Duc, Mohsen Guizanid aSchool of Computer Science and Technology, Harbin Institute of Technology, Harbin, 150001, China bInstitute of Electronic and Information Engineering of UESTC in GuangdongDongguan Guangdong 523808, China cDepartment of Computer and Information Sciences, Temple University, Philadelphia, PA 19122, USA dDepartment of Electrical and Computer Engineering, University of Idaho, Moscow, ID, USA Abstract Cloud-assisted Cognitive Internet of Things has powerful data analytics abilities based on the computing and data storage capabilities of cloud virtual machines, which makes protecting virtual machine filesystem very important for the whole system security. Agentless periodic filesystem monitors are optimal solutions to protect cloud virtual machines because of the secure and low-overhead features. However, most of the periodic monitors usually scan all of the virtual machine filesystem or protected files in every scanning poll, so lots of secure files are scanned again and again even though they are not corrupted. In this paper, we propose a novel agentless periodic filesystem monitor framework for virtual machines with different image formats to improve the performance of agentless periodic monitors. Our core idea is to minimize the scope of the scanning files in both file integrity checking and virus detection. In our monitor, if a file is considered secure, it will not be scanned when it has not been modified. Since our monitor only scans the newly created and modified files, it can check less files than other filesystem monitors.
