=== Introduction ===
2008/11/19: This is still unfinished, a work in progress, give me a couple days or email me through wiki if you have questions or concerns -BurnMage
Robert Nelson has created a couple new utilities to make managing and updating templates and containers easier, vzpkg2 pkg-cacher. So far they will create and update a large range of containers, including both 32bit and 64bit of the following:
Pkg-cacher is a transparent caching proxy daemon optimized for Debian and RPM packages. It is based on [http://www.nick-andrew.net/projects/apt-cacher/ apt-cacher], available with Debian. This version has been modified to understand RedHat RPM repositories. It also adds support for the HTTP Range header and deals correctly with files which have the same name but different content on different distributions or in some cases different versions of the same distribution.
Robert has setup an RPM repository for Fedora and CentOS installs, but when this document was written there were no repositories for Ubuntu or Debian setup yet.FIXME The source for the new vzpkg2 and templates is available on http://git.opensource-sw.net. In order to clone the updated source use the command: git clone http://git.opensource-sw.net/git/vzpkg The templates are available using: git clone http://git.opensource-sw.net/git/vztmpl
===Installation===
For CentOS:
wget http://repo.opensource-sw.net/ossw_centoscentos/ossw.repo -P /etc/yum.repos.d
For Fedora:
wget http://repo.opensource-sw.net/ossw_fedorafedora/ossw.repo -P /etc/yum.repos.d
You may wish to edit the repository file, perhaps to add a priorities setting.
yum install vzpkg2 vztmpl2-centos vztmpl2-fedora vztmpl2-debian vztmpl2-ubuntu
yum install pkg-cacher-sa =====<u>Configure vzpkg2</u>=====
Open /etc/vz/vzpkg.conf in an editor. Replace 'hostname' with the hostname or IP of the machine you are installing this on for VZPKG_CACHE_HOST, make sure not to use 'localhost', because this name is what OpenVZ Containers will use to access the pkg-cacher daemon:
VZPKG_DNS=192.168.1.2,192.168.1.3
===Source==<u>Configure pkg-cacher</u>===== ====Debian Installs:====
=====<u>Remove Old Packages</u>=====If this is an '''existing''' install, uninstall your vzpkg and vztmpl-* packages: apt-get erase vzpkg vzctl-ostmpl-* and backup & remove your current template directory: tar cjf /some/backup/location/old_templates.tbz /vz/template rm -r /vz/template If this is a '''new''' install, you should probably review the [http://download.openvz.org/doc/OpenVZ-Users-Guide.pdf OpenVZ User's Guide] and the wiki's [[Installation on Debian]] page. The source for only way you would vary your installation setups is declining to install the new default vzpkg package, and instead using vzpkg2 and templates is available on here. =====<u>Add the deb repositories to your /etc/apt/sources.list:</u>===== Add the following lines to your /etc/apt/sources.list: Etch: deb http://repo.opensource-sw.net/debian/ etch openvz deb-src http://repo.opensource-sw.net/debian/ etch openvz Sarge: deb http://repo.opensource-sw.net/debian/ sarge openvz deb-src http://gitrepo.opensource-sw.net/debian/ sarge openvz Then do: apt-get update apt-get install pkg-cacher-sa vzpkg2 =====<u>Adding New Templates:</u>===== At the time of writing the OS templates were only available in RPM format. In order To be able to clone install them, install yum: apt-get install yum Then fetch the updated source use the commandtemplates and install them: wget http://repo.opensource-sw.net/centos/5/i386/vztmpl2-centos-0.9.0-1.noarch.rpm wget http://repo.opensource-sw.net/centos/5/i386/vztmpl2-fedora-0.9.0-1.noarch.rpm git clone wget http://gitrepo.opensource-sw.net/gitcentos/5/i386/vztmpl2-debian-0.9.0-1.noarch.rpm rpm -i --nodeps vztmpl2-*.rpm Then move the templates to where Debian expects them: mv /vz/template/* /var/lib/vz/template/ Edit the /var/lib/vz/template/{centos,fedora,debian}/config/vzpkg .conf files as well to reference where Debian expects them. Change the line: baseurl=file:///vz/template/$OS_NAME/$OS_VER/$OS_ARCH/vz-addons/to: baseurl=file:///var/lib/vz/template/$OS_NAME/$OS_VER/$OS_ARCH/vz-addons/ =====<u>Configure vzpkg2</u>===== Open /etc/vz/vzpkg.conf in an editor. Replace 'hostname' with the hostname or IP of the machine you are installing this on for VZPKG_CACHE_HOST, make sure not to use 'localhost', because this name is what OpenVZ Containers will use to access the pkg-cacher daemon: VZPKG_CACHE_HOST=hostname:3142 While you are here, review this file to ensure it makes sense for your setup. In particular, you will probably have to update the VZPKG_DNS line with IP addresses of DNS servers you use. VZPKG_DNS=192.168.1.2,192.168.1.3
