Installing OpenSolaris packages from /contrib and /pending

The OpenSolaris /contrib package repository has a whole bunch of packages contributed by members of the OpenSolaris community or just by those who had a particular need for a certain package and who decided to submit it themselves.

You can install any of these packages either using the pkg command or via the package manager, you can even just go to the /contrib repository's catalog page and click on the 'install' link for the package(s) that you want to install.

To set up /contrib as a valid publisher for use with the package manager or the pkg command do the following as a user with the root role (or Software Installation profile):

pfexec pkg set-publisher -O http://pkg.opensolaris.org/contrib  contrib

Or you can add /contrib via the package manager through the File -> Manage Repositories pull down. If installing from the "install" link at http://pkg.opensolaris.org/contrib/en/catalog.shtml  the package manager will automatically add /contrib to the list of publishers.

To install packages using pkg, do the following:

pfexec pkg refresh
pfexec pkg install <package name>

You don't have to run 'pkg refresh' before installing every package, but it is probably best to do it reasonably regularly just to make sure that pkg has an up to date view of the repositories that it knows about.

There is also a /pending repository which is used to stage packages for testing while they are being made ready for promotion to /contrib. I wouldn't recommend arbitrarily using packages from /pending but you may want to provide feedback on a package, or as in the case with the ruby-mysql package, it maybe that the owner has suggested that you get it from /pending due to some issue getting it into /contrib.

To setup /pending as a publisher, you do much the same as you do for /contrib:

pfexec pkg set-publisher -O http://jucr.opensolaris.org/pending  pending

Or use the package manager File -> Manage Repositories menu.

To list the repositories that pkg knows about, run:

% pkg publisher 
PUBLISHER                             TYPE     STATUS   URI
opensolaris.org          (preferred)  origin   online   http://pkg.opensolaris.org/
contrib                               origin   online   http://pkg.opensolaris.org/contrib/
pending                               origin   online   http://jucr.opensolaris.org/pending/
mypkgs                                origin   online   http://localhost:80/
webstack                              origin   online   http://pkg.opensolaris.org/webstack/

If you have both /contrib and /pending added as publishers, when you install packages you'll need to qualify the package name with the name of the publisher from which you want to install it as follows:

pfexec pkg install pkg://pending/ruby-mysql

Which will install the 'ruby-mysql' package from the publisher name pending. Note that this is the publisher name, not the URI of the repository.

In the list of repositories above are a couple of other repositories that we've not talked about. The /webstack repository has packages that the WebStack team feel might be useful, but for which they are unable to offer support. This has packages for Web Tier applications such as Varnish and Nginx. We also sometime publish packages that are in the process of being integrated into OpenSolaris but are not yet available in the main repositories. The mypkgs repository is a repository local to our test system. It is very easy to set up a build environment for building your own packages from Spec files and then to publish them to a local repository. If you're going to do that though, you might as well publish them to /contrib via SourceJuicer.

Here's some other links that you might find useful:

Spec Files Extra is a project centered around the pkgbuild tool that builds Solaris SVR4 and/or IPS packages from spec files (and which is used by SourceJuicer)

The Genunix site has a page describing how to setup a SourceJuicer like environment

If you'd rather not get involved in submitting spec files to SourceJuicer but would like to see a package in OpenSolaris, drop us an email at sw-porters-discuss@opensolaris.org.

Nagios, Octave and SilverStripe in OpenSolaris

Several interesting packages were published to the OpenSolaris /contrib repository yesterday. They include Octave, SilverStripe and the 3 packages that make up Nagios. 

Nagios is a leading Open Source infrastructure monitoring tool that can monitor networks, hosts and even services, in fact it can monitor pretty much anything and it being Open Source it's fairly straightforward to add your own plugins. The main Nagios package is simply named nagios and delivers version 3.0.6 currently. In addition there is the nagios-plugins package which you'll install on systems that you want to monitor. A third package is nrpe (Nagios Remote Plugin Executor), which allows a centralised deployment of Nagios to execute and monitor plugins on other systems.

Octave is a GNU project, it's a high level language and runtime whose main use is for numerical computations. It's mainly command line driven, but can hook up with the likes of gnuplot in order to present graphs and other visual forms of mathematical data. I've tested it and it looks like it could be really useful for someone say, studying for a maths degree... like me for instance :o)

SilverStripe is a popular Open Source Content Management System, it's one of a number of such applications that OpenSolaris users have been clamouring for. Interestingly we did have some problems getting it to play nicely with MySQL 5.1 on OpenSolaris. When you are setting up the MySQL database prior to configuring SilverStripe modify the MySQL SMF service as follows:

svccfg -s mysql:version_51 setprop mysql/enable_64bit=true
svcadm refresh mysql:version_51
svcadm restart mysql:version_51

You'll either need to do this as root or as a user with the root role. These changes cause MySQL 5.1 to run in 64-bit mode.

You can install any of these packages either using the pkg command or via the package manager, you can even just go to the /contrib repository's catalog page and click on the 'install' link for the package(s) that you want to install.

To set up /contrib as a valid publisher for use with the package manager or the pkg command do the following as a user with the root role (or Software Installation profile):

pfexec pkg set-publisher -O http://pkg.opensolaris.org/contrib  contrib

Or you can add /contrib via the package manager through the File -> Manage Repositories pull down. If installing from the "install" link at http://pkg.opensolaris.org/contrib/en/catalog.shtml  the package manager will automatically add /contrib to the list of publishers.

To install packages using pkg, do the following:

pfexec pkg refresh
pfexec pkg install <package name>

These packages are great additions to the growing list of packages available via the /contrib repository. If you would like to contribute a package to /contrib visit the SourceJuicer page on OpenSolaris.org. If you'd rather not get involved in submitting spec files to SourceJuicer but would like to see a package in OpenSolaris, drop us an email at sw-porters-discuss@opensolaris.org.
