Need Help?

Rex is a pure open source project, you can find community support in the following places:

Professional support is also available.

Working with packages

If you want to install or remove packages on your server Rex gives you a few functions to do this. Rex tries to guess the right package provider based on the platform Rex connects to.

If you want to use a special package provider (for example, if you're using SunOS and want to use OpenCSW) you can define the package provider with package_provider_for $os => $provider_name.

Installing a Package

To install a package you can use the pkg function.

task "prepare", "server1", sub {
  pkg "apache2",
ensure => "present";
};

If you want to install multiple packages you can do it by providing an array reference.

task "prepare", "server1", sub {
  pkg [ qw/apache2 vim php5/ ],
ensure => "present";
};

If you want to install a special version of a package you just need to specify the version option.

task "prepare", "server1", sub {
  pkg "apache2",
ensure => "2.2.4";
};

Removing a Package

If you don't need a package anymore you can remove it with the remove function.

task "prepare", "server1", sub {
  pkg "apache2",
ensure => "absent";
};

Adding a Package Repository

Sometimes you have to add custom repositories to your Server. This can be done with the repository function. In the following code block you'll see an example for Debian and CentOS.

Debian

task "prepare", "server2", sub {
   # add a repository for debian/ubuntu
   repository add => "myrepo",
      url => "http://foo.bar/repo",
      distro => "squeeze",
      repository => "stable";
};

CentOS

task "prepare", "server2", sub {
   # add a repository for redhat/centos
   repository add => "myrepo",
      url => "http://foo.bar/repo";
};

After you've added a new repository you need to run update_package_db to update the package database so that you can install packages from these repositories.

task "prepare", "server2", sub {
   # add a repository for redhat/centos
   repository add => "myrepo",
      url => "http://foo.bar/repo";
      
   # update package database
   update_package_db;
};
