Ship Apache HTTPd Logs to Graylog2 Via Rsyslog

Loch_à_plateau

This is a quick recipe and a list of resources on how to ship apache logs to a graylog2 server using rsyslog which is the default system logger on CentOS 6. Tested on CentOS 6.4, Graylog2  0.9.6, Apache HTTPd 2.2.15.

By the way if like me, before I wrote this post, you are wondering about the origin of using the word that commonly describes a fresh cut piece of a tree for "our" IT logs then click on the image (talking root cause here), and don't forget to donate to wikipedia!

Handling directory copy and syncing aka “recursive copy” in Ansible 1.1

This post is no longer relevant as the copy module can do recursive copy since 1.5, also an rsync was module was added
While working on the Matterhorn Ansible playbook I've had to find a solution for copying the content of a directory from the host running the playbook to a group of hosts.Screen Shot 2013-03-30 at 6.07.36 PM

Turns out there are at least 3 ways of doing this and I thought summarizing them in one post would help other folks, worst case scenario it'll serve as a reminder for myself, so here were go.

Ansible playbook YAML “one flag per line” syntax

Screen Shot 2013-03-30 at 6.07.36 PM

I've started playing around with Ansible for Command Orchestration and Config Management and so far so good. Since I was not happy with having all the module flags in one line in my playbooks I looked for a way to break them into multiple lines.

Since Ansible playbooks are written in YAML one google search later I was on my way, here is how it works at this point, or at least according to my testing using Ansible 1.1 on a CentOS 6.3 box.

- name: "creating a config file from a rendered template"
  template: >
           src=/some/path/foobar.j2
           dest=/some/pathfoobar.conf
           owner=root
           group=wheel
           mode=0777

is equivalent to

  template: src=/some/path/foobar.j2 dest=/some/pathfoobar.conf owner=root group=wheel mode=0777

Running Rundeck Behind Apache Using mod_proxy on CentOS/RHEL6

As I just got Rundeck working behind Apache httpd with mod_proxy and since I didn't find  a dedicated tutorial  on the inter webs I thought to make a quick summary.

ChefConf 2012: I was there!

Last week I attended the inaugural ChefConf 2012, the 1st conference about Chef organized by the company at its origin i.e. OpsCode; here are some "post-conf thoughts".

If there was only one thing to note from this gathering it would be this: Amazing Community. These folks lead by example when it comes to being friendly, positive, knowledgable and willing to share, the "No Asshole Rule" is a default in real life and online. As a matter of fact even though I'm just getting started with Chef I already feel like a member of the tribe. Although I have to admit attending ChefConf 2012 wasn't a coincidence as I've been reading, listening, participating to a lot of DevOps conversations for "some" time now and Configuration Management tools such as Chef are a corner stone.

Juniper VPN client aka Network Connect on RHEL 6 (x86_64)

Ok this has taken me quite an effort so hopefully it will save you some time.

On my system RHEL 6 (x86_64) this is what it took to have the Juniper VPN client (aka Network Connect) running.

This “DevOps” thing

If you're curious about the "devops" movement there was a very good presentation by John Willis from Devops Cafe at the last "Build a Cloud Day" that I thought was a pretty good summary, truth is he sold me on his incoming book "Devops Cookbook" and the Lean Startup (which I don't think he's getting any royalties from as far as I know). Oh man Cloud and Devops in the same post, buzz word jackpot =D. Video and slides embedded from bliptv and slideshare.
