apache2/mod_proxy_balancer woes (part 1)

August 26, 2007 TheowebLeave a comment

So I’ve still been trying to get mod_proxy_balancer installed. I tried just getting a compiled mod_proxy_balancer.so and drop it into my existing apache2 install but upon start up I get:

Cannot load /usr/lib/apache2/modules/mod_proxy_balancer.so into server: /usr/lib/apache2/modules/mod_proxy_balancer.so: undefined symbol: proxy_hook_post_request

Looks like I have to do a clean uninstall and reinstall of apache2 from source. I’ll have to resetup svn (svn_dvn) and all my virtual hosts so this blog is going to be MIA while I go through this process.

I can’t wait until the Ubuntu repositories update apache2 to 2.2 so mod_proxy_balancer support will be as simple as apt-get install apache2.

I think the next step is to remove my existing apache2 install and give kodefoo’s tutorial a shot.

Here’s an interesting talk at Google by Josh Bloch, author of Java Puzzlers and special guest Bill Pugh.

I definitely learned a few things about Java from it.

I’m busy working.

Because we have a slow network, big files to deploy, and a ping pong table, work has started to look like this:

After hacking away at work for 15+ hours, I am looking at eclipse and I have no idea what I just wrote. But hey, it seems to work…sorta. So yay for that!

Making regular deposits

August 19, 2007 TheopersonalLeave a comment

Since I graduated college and got a real job, I’ve started to expand my knowledge around the world of investing. I opened up an account at Vanguard and started off with some mutual funds. The problem is I haven’t really put any more money in after that one-time lump sum for opening the account. I need to start making some regular investments through direct deposit or something. Get that dollar-cost averaging to work for me.

Pretty WordPress themes

August 19, 2007 TheowebLeave a comment

After I installed WordPress, the first thing I did was go in search for a WordPress theme. I started off at LifeHacker. After a search for all things wordpressy, I came across a post for 83 Beautiful WordPress Themes You (Probably) Haven’t Seen. After scrolling down a bit, I found Peaceful Rush which is a great match with the title of this blog. So far, I think it’s looking good 🙂

I need mod_proxy_balancer?

August 19, 2007 TheorailsLeave a comment

I have been trying to get a rails app served up by a mongrel cluster through apache. All the documentation I’ve looked at says this can be done with an Apache module mod_proxy_balancer. Looks like my apache install using apt-get does not come with that module. Blah! Guess I have to pull down the source and build from source. Hopefully, I don’t break anything!

Trying out the WP-Syntax WordPress plugin:

public class Hello {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}

Apache, Tomcat, Rails

August 19, 2007 Theojava, railsLeave a comment

It was easier than I thought it would be to install Java and Tomcat. With a few apt-get commands, I had both Java and Tomcat up and running. The next step was to serve Tomcat through Apache. This was done by using the AJP Connector. Tomcat is running with AJP connector port 8009 and I can serve up JSPs and servlet content through Apache who is listening on port 80. Pretty slick 🙂

It was even easier to get a Rails app up and running on WEBrick on default port 3000.

Next steps will be to serve Rails content through Apache.
