This describes how to update Nagios Core. This guide is about applying this update on tietar (Installation of Tietar).
Check current version of the OS, Apache and PHP.
$ cat /etc/redhat-release
CentOS release 5.7 (Final)
$ httpd -v
Server version: Apache/2.2.24
$ php -v
PHP 5.1.6
$ yum list installed | grep php
php.i386 5.1.6-27.el5_5.3 installed
php-cli.i386 5.1.6-27.el5_5.3 installed
php-common.i386 5.1.6-27.el5_5.3 installed
Check the current version of Nagios and its packages.
$ yum list installed | grep nagios
nagios.i386 3.5.0-1.el5 installed
nagios-nsca.i386 2.7.2-4.el5.rf installed
nagios-nsca-client.i386 2.7.2-4.el5.rf installed
nagios-plugins.i386 1.4.16-1.el5.rf installed
nagios-plugins-nrpe.i386 2.14-1.el5.rf installed
Check TYPO3 version at http://www.hisparc.nl/typo3/ -> 4.5
Then check the requirements for the new TYPO3 version to see if an update of any package is required.
Nagios can be updated to 3.5.0 on CentOS, from the rpm/yum CentALT repo.
$ cd /tmp
$ wget http://centos.alt.ru/repository/centos/5/i386/nagios-3.5.0-1.el5.i386.rpm
$ rpm -i --test nagios-3.5.0-1.el5.i386.rpm

Before the update Nagios gave these errors when trying to start as service:
$ service nagios start
log:
[1365710071] Failed to obtain lock on file /var/run/nagios.pid: Permission denied
[1365710071] Bailing out due to errors encountered while attempting to daemonize... (PID=15845)
From: Failed to obtain lock on file /var/run/nagios.pid
Changing the value of lock_file in /etc/nagios/nagios.cfg from /var/run/nagios.pid to /tmp/nagios.pid allowed the PID to be written and the init script to succeed.
Change lock_file location to a place with read+write permissions.
