| − | This document briefly describes the steps needed to install OpenVZ on your Debian 7 "Wheezy" machine. For RHEL/Centos 6 based systems, please see [[Quick installation]].
| + | #REDIRECT [[Installation on Debian 9]] |
| − | | |
| − | {{Out|A commercial version of OpenVZ is available, which simplifies installation with a single disk as well as supports networked installation using PXE boot. To learn more about Parallels Cloud Server and request a free trial, please see http://www.parallels.com/products/pcs/}}

| − | | |
| − | == Requirements ==
| |
| − | | |
| − | This guide assumes you are running '''Debian 7 "Wheezy" ''' for '''AMD64''' on your system (x86 is not yet supported).
| |
| − | | |
| − | === /vz file system ===
| |
| − | | |
| − | It is recommended to use a separate partition for containers (by default '''/var/lib/vz''') and format it to '''ext4'''.
| |
| − | | |
| − | === apt pre-setup ===
| |
| − | | |
| − | {{Note|For more info about Debian repositories, see http://download.openvz.org/debian.}}
| |
| − | | |
| − | Run the following:
| |
| − | | |
| − | <pre><nowiki>cat << EOF > /etc/apt/sources.list.d/openvz-rhel6.list
| |
| − | deb http://download.openvz.org/debian wheezy main
| |
| − | #deb http://download.openvz.org/debian wheezy-test main
| |
| − | EOF</nowiki></pre>
| |
| − | | |
| − | Import GPG key used for signing repository:
| |
| − | | |
| − | <pre><nowiki>wget http://ftp.openvz.org/debian/archive.key
| |
| − | apt-key add archive.key</nowiki></pre>
| |
| − | | |
| − | Update the local cache:
| |
| − | apt-get update
| |
| − | | |
| − | == Kernel installation ==
| |
| − | | |
| − | Limited OpenVZ functionality is supported when you run a recent 3.x kernel (check [[vzctl for upstream kernel]], so OpenVZ kernel installation is optional but still recommended.
| |
| − | | |
| − | # apt-get install linux-image-openvz-amd64
| |
| − | | |
| − | == System configuration ==
| |
| − | | |
| − | <!-- this is not yet in vzctl.deb
| |
| − | {{Note|With vzctl 4.6 or newer there is no need to do manual configuration. Skip to [[#Tools_installation]].}}
| |
| − | -->
| |
| − | | |
| − | Please make sure the following steps are performed before rebooting into OpenVZ kernel.
| |
| − | | |
| − | === sysctl ===
| |
| − | | |
| − | There are a number of kernel parameters that should be set for OpenVZ to work correctly. These parameters are stored in <tt>/etc/sysctl.conf</tt> file. Here are the relevant portions of the file; please edit accordingly.
| |
| − | | |
| − | <pre>
| |
| − | # On Hardware Node we generally need
| |
| − | # packet forwarding enabled and proxy arp disabled
| |
| − | net.ipv4.ip_forward = 1
| |
| − | net.ipv6.conf.default.forwarding = 1
| |
| − | net.ipv6.conf.all.forwarding = 1
| |
| − | net.ipv4.conf.default.proxy_arp = 0
| |
| − | | |
| − | # Enables source route verification
| |
| − | net.ipv4.conf.all.rp_filter = 1
| |
| − | | |
| − | # Enables the magic-sysrq key
| |
| − | kernel.sysrq = 1
| |
| − | | |
| − | # We do not want all our interfaces to send redirects
| |
| − | net.ipv4.conf.default.send_redirects = 1
| |
| − | net.ipv4.conf.all.send_redirects = 0
| |
| − | </pre>
| |
| − | | |
| − | == Tools installation ==
| |
| − | | |
| − | {{Out|Before installing tools, please read about [[vzstats]] and opt-out if you don't want to help the project.}}
| |
| − | | |
| − | OpenVZ needs some user-level tools installed:
| |
| − | | |
| − | # apt-get install vzctl vzquota ploop
| |
| − | | |
| − | == Reboot into OpenVZ kernel ==
| |
| − | | |
| − | Now reboot the machine and choose an entry with word "openvz" in the boot loader menu (it should be default choice).
| |
| − | | |
| − | == Download OS templates ==
| |
| − | | |
| − | {{Note|this step is optional, vzctl is able to download templates on demand.}}
| |
| − | | |
| − | An OS template is a Linux distribution installed into a container
| |
| − | and then packed into a gzipped tarball. Using such a cache, a new container
| |
| − | can be created in a minute.
| |
| − | | |
| − | Download precreated template caches from [http://openvz.org/download/template/cache Downloads » Templates » Precreated], or directly from [http://download.openvz.org/template/precreated/ download.openvz.org/template/precreated], or from one of the [[Download mirrors|mirrors]]. Put those tarballs '''as-is (no unpacking needed)''' to the <tt>/vz/template/cache/</tt> directory.

| − | == Next steps ==
| |
| − | | |
| − | OpenVZ is now set up on your machine. Follow on to [[basic operations in OpenVZ environment]] document.
