Patching Checkinstall to save options between runs

By jbayer - Last updated: Thursday, April 5, 2012

I had a problem where I was working on an existing, installed package for our systems here.  I needed to have the new RPMs be the same as the old ones, except for the release number being incremented.  Checkinstall, while a great program, doesn’t do anything to save options, so you have to re-enter them […]

Installing Zabbix on a CentOS/RedHat system (Updated)

By jbayer - Last updated: Friday, December 23, 2011

I needed to do several repeated installs of Zabbix, on both a CentOS 5.6 and Centos 6.1 system.  I also noted that Zabbix had been updated, along with a couple of other version changes.  This version also allows you to do upgrades on an existing system.  However, the upgrade has only been tested on installations […]

Setting up a private RPM repo

By jbayer - Last updated: Tuesday, August 9, 2011

I had a local need for a private repo, for some of our locally-built RPMS. Since I’ve previously set up a private mirror, I decided to write a script which would both setup the directory structure I needed, and to do whatever rsyncing would be needed for a mirror. To install, just copy it into […]

Installing Zabbix on a CentOS/Scientific Linux/RedHat 6 system

By jbayer - Last updated: Monday, August 8, 2011

This is a followup to my previous post about installing Zabbix.  The previous script was configured to install Zabbix to a 5.5 or 5.6 system.  Now that 6 has been out for a while, I’ve updated the script to install Zabbix on a 6.0 or 6.1 system. The previous instructions are still valid.  Just download […]

Error with checkinstall on 64 bit system

By jbayer - Last updated: Friday, July 15, 2011

The following error can occur on 64 bit systems when trying to use the checkinstall program: ERROR: ld.so: object ‘/usr/local/lib64/installwatch.so’ from LD_PRELOAD cannot be preloaded: ignored.

Speeding up a Zabbix installation

By jbayer - Last updated: Thursday, July 7, 2011

The Zabbix dashboard uses a lot of javascript.  Javascript isn’t cached, so this is a way to force it to be cached. This script assumes that Zabbix is installed in /usr/local/share/zabbix, if it is elsewhere you will have to modify the first few lines. This script will rename the javascript files to PHP files, and […]
