| − | + | This guide assumes you are running '''RHEL (CentOS, Scientific Linux) 6''' on your system. Currently, this is a recommended platform to run OpenVZ on. | |
| − | === | + | === /vz file system === |
| − | + | It is recommended to use a separate partition for containers (by default '''/vz''') and format it to '''ext4'''. | |
| − | === | + | === yum pre-setup === |
| − | + | Download [http://ftp.openvz.org/openvz.repo openvz.repo] file and put it to your <code>/etc/yum.repos.d/</code> repository: | |
<pre><nowiki>wget -P /etc/yum.repos.d/ http://ftp.openvz.org/openvz.repo</nowiki></pre> | <pre><nowiki>wget -P /etc/yum.repos.d/ http://ftp.openvz.org/openvz.repo</nowiki></pre> | ||
| − | + | Import OpenVZ GPG key used for signing RPM packages: | |
<pre><nowiki>rpm --import http://ftp.openvz.org/RPM-GPG-Key-OpenVZ</nowiki></pre> | <pre><nowiki>rpm --import http://ftp.openvz.org/RPM-GPG-Key-OpenVZ</nowiki></pre> | ||
| − | == | + | == 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. | |
# yum install vzkernel | # yum install vzkernel | ||
| − | == | + | == System configuration == |
| − | {{Note| | + | {{Note|With vzctl 4.4 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 === | === 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. | |

| − | SELinux | + | SELinux should be disabled. Put <code>SELINUX=disabled</code> to <code>/etc/sysconfig/selinux</code>: |
echo "SELINUX=disabled" > /etc/sysconfig/selinux | echo "SELINUX=disabled" > /etc/sysconfig/selinux | ||
| − | == | + | == Tools installation == |
| − | {{Out| | + | {{Out|Before installing tools, please read about [[vzstats]] and opt-out if you don't want to help the project.}} |
| − | OpenVZ | + | OpenVZ needs some user-level tools installed: |
# yum install vzctl vzquota ploop | # yum install vzctl vzquota ploop | ||
| − | == | + | == Reboot into OpenVZ == |
| − | + | Now reboot the machine and choose "OpenVZ" on the boot loader menu (it should be default choice). | |
| − | == | + | == Download OS templates == |
| − | + | 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 | + | OpenVZ is now set up on your machine. Follow on to [[basic operations in OpenVZ environment]] document. |
