If you have activation key: $ wget https://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy $ sh cldeploy -k <activation_key> If you have IP-based license: $ sh cldeploy -i $ reboot 2 Contents CloudLinux Documentation Documentation, Release latest Once you have rebooted, you are running CloudLinux kernel with LVE enabled. The script automatically detects and supports the following control panels: cPanel with EA3, Plesk, DirectAdmin, InterWorx. It will install CloudLinux kernel, Apache module, PAM module, command line tools as well as LVE Manager. ISPmanager 5 has native support for CloudLinux. To deploy CloudLinux on a server with ISPmanager 5, you would need to purchase CloudLinux license directly from ISPSystems and follow ISPmanager’s deployment guide. Note. If you are converting Hyper-V server, please, make sure you upgrade to the latest CentOS 6.9 or CentOS 7.4 first.

Install CloudLinux kernel, lve libraries, lve-utils, lve- 2. stats and pam_lve packages. Contents 3 CloudLinux Documentation Documentation, Release latest It will attempt to detect control panel and do the follow- 3. ing actions: For cPanel & DirectAdmin: 1. recompile Apache to install mod_hostinglimits; 1. install LVE Manager. 2. For Plesk, ISPManager & InterWorx: 2. Update httpd and install mod_hostinglimits; 1. install LVE Manager. 2. To disable installation of LVE Manager and mod_hostinglimits, please use –conversion-only option. To disable installation of kernel & CLN registration, please use –components-only option. To install mod_hostinglimits only, use –hostinglimits option. Examples: $ cldeploy –key xx-xxxxxx # convert RHEL/CentOS to CL by using activation key, install control panel components $ cldeploy –byip –conversion-only # convert RHEL/CentOS to CL by ip, don’t install control panel components $ cldeploy –components-only # install control panel components on already converted system $ cldeploy –hostinglimits # update httpd and install mod_hostinglimits Explanation Of Changes CloudLinux uses the fact that it is very close to CentOS and RHEL to convert systems in place, requiring just one reboot. Our conversion script does the following actions: •Backup of original repository settings into /etc/cl-convert-saved. 4 Contents CloudLinux Documentation Documentation, Release latest •Backup of RHEL system id into /etc/cl-convert-saved (RHEL systems only). •Installs CL repository settings & imports CL RPM key. •Replaces redhat/centos-release, redhat-release-notes, redhat-logos with CL version. •Removes cpuspeed RPM (as it conflicts with CPU limits). •Re-installs CL version of rhnlib/rhnplugin. •Checks for binary kernel modules, finds replacement if needed. •Detects OVH servers and fixes mkinitrd issues. •Detects Linode servers and fixes grub issues. •Checks if LES is installed. •Checks that /etc/fstab has correct /dev/root •Checks for efi. •Installs CL kernel, lve-utils, liblve, lve-stats RPMs. •Installs LVE Manager for cPanel, Plesk, DirectAdmin, ISPManager & InterWorx •Installs mod_hostinglimits apache module: oRPM install for Plesk, ISPManager & InterWorx; oOn Plesk, replaces psa-mod_fcgid* with mod_fcgid; oEasyApache rebuild for cPanel; ocustombuild for DA. Script for converting back: •Restores CentOS repositories, and centos-release/release-notes/logos. •Removes lve, mod_hostinglimits, lve-stats, lvemanager. •mod_hostinglimits RPM is removed. The kernel is not removed - to prevent condition when server has no kernels and wouldn’t boot. The command line to remove the kernel is provided. On cPanel servers, rebuild of Apache with EasyApache will complete the conversion back, but doesn’t have to be performed immediately. On DirectAdmin servers, rebuild of Apache with custombuild will complete the conversion back, but doesn’t have to be performed immediately.

VPS merupakan sebuah cara untuk membagi sumber daya sebuah physical server menjadi server virtual. Sebuah VPS memerlukan control panel karena untuk mempermudah pengaturan seperti mengelola email, disk, database, penambahan domain, memonitor bandwidth dan backup data. Terdapat berbagai macam control panel dengan spesifikasi yang berbeda-beda. Pemilihan control panel tersebut sangat penting karena control panel tersebut harus disesuaikan dengan spesifikasi VPS. Berdasarkan permasalahan tersebut, diperlukan sistem yang dapat membantu dalam pengambilan keputusan dalam pemilihan control panel. Metode yang digunakan dalam penelitian ini adalah dengan menggunakan metode Analitical Hierarcy Process (AHP) dan Simple Additive Weighting (SAW). Metode AHP digunakan untuk mencari bobot variabel kriteria, sedangkan metode SAW digunakan untuk menentukan nilai akhir dan perangkingan. Hasil perangkingan alternatif control panel pada sistem ini menunjukkan hasil yang sama dengan hasil perangkingan dari pakar control panel, sehingga sistem ini dapat digunakan oleh pengguna sebagai dasar pengambilan keputusan dalam menentukan pemilihan alternatif control panel. Kata Kunci — control panel, VPS, AHP, SAW, sistem pendukung keputusan Abstract Hosting can be divided into various types, one of them is Virtual Private Server (VPS).

  • Checkpoint and Restoration of Micro-Service in Docker Containers
    3rd International Conference on Mechatronics and Industrial Informatics (ICMII 2015) Checkpoint and Restoration of Micro-service in Docker Containers Chen Yang School of Information Security Engineering, Shanghai Jiao Tong University, China 200240 [email protected] Keywords: Lightweight Virtualization, Checkpoint/restore, Docker. Abstract. In the present days of rapid adoption of micro-service, it is imperative to build a system to support and ensure the high performance and high availability for micro-services. Lightweight virtualization, which we also called container, has the ability to run multiple isolated sets of processes under a single kernel instance. Because of the possibility of obtaining a low overhead comparable to the near-native performance of a bare server, the container techniques, such as openvz, lxc, docker, they are widely used for micro-service [1]. In this paper, we present the high availability of micro-service in containers. We investigate capabilities provided by container (docker, openvz) to model and build the Micro-service infrastructure and compare different checkpoint and restore technologies for high availability. Finally, we present preliminary performance results of the infrastructure tuned to the micro-service. Introduction Lightweight virtualization, named the operating system level virtualization technology, partitions the physical machines resource, creating multiple isolated user-space instances. Each container acts exactly like a stand-alone server. A container can be rebooted independently and have root access, users, IP address, memory, processes, files, etc. Unlike traditional virtualization with the hypervisor layer, containerization takes place at the kernel level. Most modern operating system kernels now support the primitives necessary for containerization, including Linux with openvz, vserver and more recently lxc, Solaris with zones, and FreeBSD with Jails [2].

  • Evaluating and Improving LXC Container Migration Between
    Evaluating and Improving LXC Container Migration between Cloudlets Using Multipath TCP By Yuqing Qiu A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Applied Science in Electrical and Computer Engineering Carleton University Ottawa, Ontario © 2016, Yuqing Qiu Abstract The advent of the Cloudlet concept—a “small data center” close to users at the edge is to improve the Quality of Experience (QoE) of end users by providing resources within a one-hop distance. Many researchers have proposed using virtual machines (VMs) as such service-provisioning servers. However, seeing the potentiality of containers, this thesis adopts Linux Containers (LXC) as Cloudlet platforms. To facilitate container migration between Cloudlets, Checkpoint and Restore in Userspace (CRIU) has been chosen as the migration tool. Since the migration process goes through the Wide Area Network (WAN), which may experience network failures, the Multipath TCP (MPTCP) protocol is adopted to address the challenge. The multiple subflows established within a MPTCP connection can improve the resilience of the migration process and reduce migration time. Experimental results show that LXC containers are suitable candidates for the problem and MPTCP protocol is effective in enhancing the migration process. i Acknowledgement I would like to express my sincerest gratitude to my principal supervisor Dr. Chung-Horng Lung who has provided me with valuable guidance throughout the entire research experience. His professionalism, patience, understanding and encouragement have always been my beacons of light whenever I go through difficulties. My gratitude also goes to my co-supervisor Dr.
