For many years, building and installing third-party software on Solaris has been a huge pain. For people who do not use pkgsrc, that is.
Originating from the NetBSD project, pkgsrc is a source-based cross-platform package manager. If you've used FreeBSD ports, then it is very similar as it derives from the same codebase, so the basic premise is that you
$ cd /usr/pkgsrc/www/apache22
$ make package
and pkgsrc will download the source for Apache 2.2, compile it and all dependancies, install it on the local system and create a package which can be installed on other similar systems.
However, we've taken ports further and applied the NetBSD philosophy of portability, meaning that it not only works on NetBSD, but across all *BSD as well as Linux, OSX, HP/UX, AIX, IRIX, QNX, Windows (via Interix), and of course Solaris.
So while apt-get might be awesome, it only really works on Linux. FreeBSD might have way more ports than us, but only runs on FreeBSD and OSX. pkgsrc provides a consistent interface across all the platforms listed above, and in many cases provides a far superior package manager than the system provides.
Here's how I use pkgsrc on Solaris, in this specific case Solaris 10/x86. Paths are specific to my setup, you can of course change them.
Create a chroot/zone environment
I use the zones feature of Solaris 10 to ensure that all packages are built in a sandbox. This has a number of benefits:
- The running system is unaffected by the builds, in that they are not writing to the same file system. This is good when you have misbehaving packages.
- You can separate the build and install phases, so that you can verify all the packages have been built and are correct before starting any install/upgrade procedure
- It's easier to catch package mistakes, e.g. unpackaged files.
- It avoids pollution from the host environment which may produce bad packages
I wrote two scripts, create-zone for starting the zone and delete-zone for stopping and removing it. If you want to use them then there are some variables to set at the top, and you may want to scan through them for additional bits to change (e.g. create-zone copies my ssh public key which will most likely be wrong for your setup :-)
One additional piece of configuration for create-zone is an optional SMF xml file. I use this file to disable inetd inside the zone for additional security. You can do other bits if you like, or just not bother. The file should be named <yourzonename>.xml
Fetch pkgsrc
pkgsrc is developed very rapidly. Tracking nearly 9,000 pieces of third-party software means there are always many updates. Thankfully, we provide quarterly branches for people who want more stability, and I recommend using the latest quarterly release. At time of writing, this is known as 'pkgsrc-2009Q2'. Within the next month or so we will release pkgsrc-2009Q3, and you can figure out the names of future releases yourself.
The easiest way to get pkgsrc is using cvs. I keep stuff like this under /content as opposed to the default of /usr, you can use whatever you wish but will need to change all my example scripts to match where you put it.
$ cd /content
$ cvs -d anoncvs@anoncvs.netbsd.org:/cvsroot co -rpkgsrc-2009Q2 -dpkgsrc-2009Q2 -P pkgsrc
Alternatively, you can fetch either bzip2 or gzip archives of the current branch. I recommend the cvs method as, with the branch being updated for security fixes and other important changes, you can easily track it using
$ cd /content/pkgsrc-2009Q2
$ cvs update
pkgsrc configuration
You can download my mk.conf here. This is the primary configuration file for pkgsrc. Again, you may need to tailor this to your environment, and may find it useful to read the pkgsrc guide to understand what it all means.
As I do a lot of pkgsrc development I have a number of virtual machines up and running doing various bits and pieces. Obviously I don't want to copy that mk.conf around, so I also have a small fragment file which is appended to each virtual machine's mk.conf (using bootstrap's --mk-fragment argument) and includes the global copy.
The bulk build setup in pkgsrc requires its own configuration, and for this you will need to edit a file inside pkgsrc. There is an example file provided, so what I usually do is symlink this to the real copy then I can easily keep it up-to-date via cvs.
$ cd /content/pkgsrc-2009Q2/mk/bulk
$ ln -s build.conf-example build.conf
$ vi build.conf
Again, you can find my personal build.conf here
Finally, there is a configuration file for pkg_chk which is a package inside pkgsrc which makes managing upgrades easier (ideally it should be a part of the main pkgsrc tools but that's for another day). pkgchk.conf is a list of package directories, relative to the pkgsrc top level, which are to be built and installed for this setup. If you have a large installation then pkg_chk has extra features to make it possible to share pkgchk.conf across a number of machines and configure packages on a per-host, per-OS etc basis.
It is highly likely you will want to change the pkgchk.conf file from what I use :-)
Build scripts
Once everything is set up, I have two scripts to build then update my packages, intuitively called build-packages and update-packages. These are pretty simple as all the hard work has all been done. build-packages is ran inside the zone, then update-packages on the main host. These scripts hardcode the name of the branch currently used, so you will need to update this when moving to newer releases.
Quick recap
Ok, so here is the stuff I have for my setup and where I keep them.
/content/pkgsrc-2009Q2
|
Checked out pkgsrc tree, "2009Q2" branch |
/content/scripts/create-zone
|
Creates Solaris zone |
/content/scripts/delete-zone
|
Uninstalls and deletes zone |
/content/scripts/build-packages
|
Bulk build packages inside the zone |
/content/scripts/update-packages
|
Updates installed packages |
/install/pkgsrc/misc/mk.conf
|
Main pkgsrc configuration file |
/install/pkgsrc/misc/mk-include.conf
|
Fragment file included in each zone's mk.conf, sources the global mk.conf |
/install/pkgsrc/misc/pkgchk.conf
|
pkg_chk configuration file |
/install/zones/vm-generic.xml
|
Shared SMF configuration file, symlinked to from e.g. "vm0.xml" |
These are the paths where stuff will be created
/install/pkgsrc/distfiles
|
Source tarballs of packages |
/install/pkgsrc/packages/2009Q2
|
Resulting binary packages |
/tmp/pkgsrc
|
Temporary build area for packages |
/content/vwww/www.adsl.perkin.org.uk/pkgstat
|
Bulk build results directory
|
It's definitely harder than it should be to get this all setup, but the good news is that once it's done there's very little maintenance.
Kicking it all off
Once everything is setup:
$ /content/scripts/create-zone vm0
$ ssh vm0 /content/scripts/build-packages
$ /content/scripts/update-packages
$ /content/scripts/delete-zone vm0
This should do the lot. Once build-packages has finished you should, if you configured your email address in build.conf, get an email with the bulk build results which looks similar to this:
http://mail-index.netbsd.org/pkgsrc-bulk/2009/08/23/msg006883.html
A fuller report is available if you configure a web server to serve the 'pkgstat' directory created by the bulk build, and this can help debug problems (again see the above URL for an example).
You will need to add /opt/pkg/sbin:/opt/pkg/bin to $PATH. Configuration files are in /etc/opt/pkg, and log files and metadata are kept in /var/opt/pkg
This stuff should be obsolete
While this all works well for me, it's pretty lame for users who just want to install packages and have stuff work. I'm working on providing regular updates of binary packages, including a SVR4 package of the bootstrap kit, so that in theory all a user needs to do is
$ pkgadd TNFpkgsrc.pkg
$ pkg_add apache22
$ pkg_chk -aurb # upgrades all installed packages to latest releases
I'm almost there, just needs some tidying up and regular builds. Please feel free to help out!
