Installing GEARMAN on MAC OSX 10.6

9 Comments


So, today I set about installing gearmand on my laptop, to test out some massively distributed computing ideas I’m working on. Turns out, it’s not just a matter of downloading the .dmg file and hitting ‘RUN’. Nope.. you better have 1/2 a pot of coffee and your copy of XCode installed on the machine or you are dead in the water.

Actually, you’re going to need more than that, if you are working with a vanilla Snow Leopard install.

Step 1 – install XCode:

But first things first. You can download XCode from the Apple website, or you can install it from your ‘Extras’ folder on the OS disk. I did the later, since the distro is pretty big, something like 600MB. Get that done first.

Step 2 – install MacPorts:

Now this is where the fun begins. Now, if you followed my other blog page on installing MacPorts, you can move onto Step 3. If you have not, then, proceed at hast to installing it (follow this link too).

Step 3 – install libevent

If you enjoyed installing MacPorts, you are going to LOVE this! 🙂 Now, the step of building libevent from source, probably not *required* but, after three installs that were not picked up by the gearmand, I though I’d just, do this the old fashioned way too. I have a writeup for installing libevent here (link to my page).

Step 3 – install wget

wget. How I love you, let me count the ways… MANY. wget is great. It’s a non-interactive text web client. Some of the cool things that wget can do, is recursively traverse a page, grabbing all the content, images, links pages (and their images, objects etc.). It’s also almost impossible to compromise with conventional XSS or other tricky DOM / JavaScript methods. No drive-by downloads here folks!

So, go ahead and get wget installed, because it’s going to be used to reach the final objective, retrieving gearman.

#root: port install wget

For me, on my lousy ComCrap connection, it took me a fairly long time. I think it’s safe to say, run the install command, and walk away. Check back in 10-15 minutes, see if it’s done. How will you konw if it worked? Simple, if you download the file in Step 5, it worked.

Step 5 – Finally, download and extract the Gearman bundle

This is where wget comes into play. Make sure you are in the directly you want. I suggest /opt. And execute the wget command to grab the distro. NOTE: The current distribution might be later than this (higher number). A check of the Gearman main site will probably give you the number you need, if this is not the latest and greatest:

#root: wget http://launchpad.net/gearmand/trunk/0.12/+download/gearmand-0.12.tar.gz
#root: gunzip gearmand-0.12.tar.gz,
#root: tar xvf gearmand-0.12.tar

Step 6 – BUILD!

Build the package. This part is the simplest of all the steps.

#root: ./configure
#root: make
#root: make install

YOU ARE DONE (installing that is)

Next article, will be a writeup on how to use Gearman, some time in the next week.

NOTE: This is part of a series of posts, centered around installation and evaluation of Gearman as a distributed scheduling product. Here are the other articles in this group:

Installing libevent on MAC OSX 10.6

6 Comments

So, today I set about installing libevent on my laptop. It’s a required library for system event handling applications. An example of that would be Gearman.

First off, you are going to need to have install MacPorts installed.

Step 1 – install MacPorts:

Now this is where the fun begins. Now, if you followed my other blog page on installing MacPorts, you can move onto Step 3. If you have not, then, proceed at hast to installing it (follow this link too).

Step 2 – install libevent

If you enjoyed installing MacPorts, you are going to LOVE this! 🙂 Now, the step of building libevent from source, probably not *required* but, after three installs that were not picked up by the gearmand, I though I’d just, do this the old fashioned way too.

First off, run the standard install. This did not toss errors for me on the normal install. You can stop with this Step after it installs and move of if you like. I’m going to show the extra couple of steps I took.

#root: port install libevent

Step 3 – locate tarball, extract and build from source

UPDATE: 6-JUN-2013. Get the latest tarball from [HERE].

Now, move the distribution for libevent, and untar the tarball. The path here is from my current build. The one you eventually get will possibly have a higher number (more recent build). Don’t freak out if this exact path is not on your system. If you are building from source, I’m going to assume you also know how to find things on your computer. The reason I built this from source, was to provide the option –prefix=/usr/local to configure. It establishes where it will deploy it’s libraries.

#root: cd local/var/macports/distfiles/libevent
#root: gunzip libevent-1.4.13-stable.tar.gz
#root: cd /opt
#root: tar xvf libevent-1.4.13-stable.tar
#root: cd libevent-1.4.13-stable
#root: make
#root: make install

Now, you should have a nice clean build of libevent on your computer. Having accomplished this, you can install an array of scheduling and system event driven applications.

Enjoy.
