This === Introduction === 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: * Centos 4 and 5,* Fedora 7, 8 and 9,* Debian Sarge and Etch,* Ubuntu Feisty, Gutsy and Hardy. Pkg-cacher is a place holder 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. The source for the page BurnMage new vzpkg2 and templates is going available on http://git.opensource-sw.net. In order to update with instructions culled from 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=== ====Remove Old Packages & Templates==== * Backup your existing /vz/template directory and clear it out.* Uninstall vzpkg and any vztmpl-* packages. ====Centos & Fedora installs:==== =====<u>Remove Old Packages</u>=====If this is an '''existing''' install, uninstall your vzpkg and vztmpl-* packages: yum remove vzpkg vztmpl-* 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 mailing list-Guide.pdf OpenVZ User's Guide] and the wiki's [[Quick installation]] page. The only way you would vary your installation setups is declining to install the default vzpkg package, and instead using vzpkg2 here. =====<u>Download the repository file for your OS</u>===== For CentOS: wget http://repo.opensource-sw.net/ossw_centos.repo -P /etc/yum.repos.d For Fedora: wget http://repo.opensource-sw. from emails by Robert Nelson on how net/ossw_fedora.repo -P /etc/yum.repos.d You may wish to edit the repository file, perhaps to add a priorities setting. =====<u>Install vzpkg2 and pkg-cacher</u>===== Once the repository is added in /etc/yum.repos.d, you can now install the new vzpkg2 and pkg-cacherfrom it: yum install vzpkg2 vztmpl2-centos vztmpl2-fedora vztmpl2-debian vztmpl2-ubuntu yum install pkg-cacher 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
