Rex::Commands::Pkg - Install/Remove Software packages
With this module you can install packages and files.
install file => "/etc/passwd", { source => "/export/files/etc/passwd" }; install package => "perl";
The install function can install packages (for CentOS, OpenSuSE and Debian) and files.
task "prepare", "server01", sub { install package => "perl"; # or if you have to install more packages. install package => [ "perl", "ntp", "dbus", "hal", "sudo", "vim", ]; };
This is deprecated since 0.9. Please use File file instead.
task "prepare", "server01", sub { install file => "/etc/passwd", { source => "/export/files/etc/passwd", owner => "root", group => "root", mode => 644, }; };
task "prepare", "server01", sub { install file => "/etc/httpd/apache2.conf", { source => "/export/files/etc/httpd/apache2.conf", owner => "root", group => "root", mode => 644, on_change => sub { say "File was modified!"; } }; };
task "prepare", "server01", sub { install file => "/etc/httpd/apache2.tpl", { source => "/export/files/etc/httpd/apache2.conf", owner => "root", group => "root", mode => 644, on_change => sub { say "File was modified!"; }, template => { greeting => "hello", name => "Ben", }, }; };
This function will remove the given package from a system.
task "cleanup", "server01", sub { remove package => "vim"; };
This function returns all installed packages and their version.
task "get-installed", "server1", sub { for my $pkg (installed_packages()) { say "name : " . $pkg->{"name"}; say " version: " . $pkg->{"version"}; } };
This function updates the local package database. For example, on CentOS it will execute yum makecache.
task "update-pkg-db", "server1", "server2", sub { update_package_db; install package => "apache2"; };
Add or remove a repository from the package manager.
For Debian: If you have no source repository, or if you don't want to add it, just remove the source parameter.
task "add-repo", "server1", "server2", sub { repository "add" => "repository-name", url => "http://rex.linux-files.org/debian/squeeze", distro => "squeeze", repository => "rex", source => 1; };
For CentOS, Mageia and SuSE only the name and the url are needed.
task "add-repo", "server1", "server2", sub { repository add => "repository-name", url => 'http://rex.linux-files.org/CentOS/$releasever/rex/$basearch/'; };
To remove a repository just delete it with its name.
task "rm-repo", "server1", sub { repository remove => "repository-name"; };
To set an other package provider as the default, use this function.
user "root"; group "db" => "db[01..10]"; package_provider_for SunOS => "blastwave"; task "prepare", group => "db", sub { install package => "vim"; };
This example will install vim on every db server. If the server is a Solaris (SunOS) it will use the blastwave Repositories.
