Tweet At my job at OpenSky we have a common NFS share that is failed over to a slave nfs node if the master dies. It was setup so that the slave would just rsync from the master. This was done to save time. Not that I have some time, I decided to finally setup drbd on the two nodes to keep the files always in sync. So below are my nodes with hostnames/ips and drive information

Tweet I am recently getting into MongoDB. Thanks to my company (OpenSky) sending me to MongoNYC event. I am also tasked with setting up infrastructure to run MongoDB. So we are starting off with a simple master/slave MongoDB setup. I always thought MySQL was easy to setup replication on but MongoDB proves it just gets easier. This will expect you are using the official MongoDB provided RPMs from their repository.

Tweet I wrote a bit better init.d script for Jira for Redhat/CentOS The first thing you want to do is create a sysconfig file. Below is the filename /etc/sysconfig/jira The file has the following contents in it # # The user Jira runs as # JIRA_USER=jira # # The home directory of Jira # JIRA_HOME=/opt/jira/current Now create the init.d script /etc/init.d/jira It has the following contents in it.

Tweet Fabric is a great tool for helping deploy applications. It is written in Python and still in it’s early stages. The big issue is that fabric will not run on python v2.4. That is a problem since Redhat/CentOS v5 ships with v2.4 so we have to make it work. So the first thing to do is install python 2.5. I found great rpms here. I am going to mirror the RPMS on my blog just in case.

Tweet There is a great project called Bash Paranoia. Right now their site is busted so I can’t link to it. Its a patch that applies to bash that allows commands to be logged to syslog. I basically took this one step further and added curl support. The bash paranoia patch and my curl addition can be found on my GitHub project page http://github.com/mzupan/bash-paranoia-curl Below is my patch I wrote.
