−	#~~REDIRECT~~ [[Installation on Debian]]	+	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]].
		+
		+	{{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''' or '''i686'''.
		+
		+	=== /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>
		+
		+	{{Note\|The second line with wheezy-test is commented out. This is a testing repo with newer kernels and possibly tools. Enable it if you want to stay on a bleeding edge of technology.}}
		+
		+	Import GPG key used for signing repository:
		+
		+	<pre><nowiki>wget ftp://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 highly recommended.
		+
		+	# apt-get install linux-image-openvz-amd64
		+
		+	Or, if you still have i686:
		+
		+	# apt-get install linux-image-openvz-686
		+
		+	== 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 vzstats
		+
		+	== 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.
		+
		+	== See also ==
