Hi,

Merethis has released Centreon 2.1.8 (I’ve missed the 2.1.7 :))
The update is very simple:

cd /usr/local/src
sudo wget http://download.centreon.com/index.php?id=140
sudo tar -xzf centreon-2.1.8.tar.gz
cd centreon-2.1.8
sudo ./install.sh -u /etc/centreon

After accepting the license, simply answer yes to all the questions you’ll see.

When finished, connect to the web interface and follow the “NEXT, NEXT, NEXT” steps.
Your database will be updated twice (from 2.1.6 to 2.1.7 then from 2.1.7 to 2.1.8).

It’s finished.

Enjoy Continue reading »

Migrate your Centreon from Ubuntu 8.04 LTS to Ubuntu 10.04 LTS

This time, we will try to migrate our centreon solution from our previous Ubuntu 8.04 LTS to our new Ubuntu 10.04 LTS edition (It should work for other version too).
To do that, you should have the same centreon version on both side (for database scheme compatibility).
I use the same IP address for my both servers (it’s for a complete replacement)

Backup your Ubuntu 8.04 LTS solution

sudo service nagios stop
sudo service centstorage stop
sudo /usr/local/centreon/cron/purgeCentstorage
sudo service centcore stop
sudo service ndo2db stop

If you are planning to monitor Windows servers, it’s highly advised to install NRPE module. On windows side, I generaly use NSCLIENT++ for host check.

You’ll be able to execute remote commands on hosts.

Installation process:

cd /usr/local/src
sudo wget http://downloads.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.12/nrpe-2.12.tar.gz?use_mirror=kent
sudo tar xzfv nrpe-2.12.tar.gz
cd nrpe-2.12/
sudo ./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib
sudo make all
sudo make install-plugin

Centreon syslog configuration update on Ubuntu 10.04 LTS

Hi,

I’ve corrected the rsyslog installation process concerning the xconsole section.
In fact as we did not use X server, we did not need this part.

Here is the diff:

Edit 50-default.conf to correct the path

sudo nano /etc/rsyslog.d/50-default.conf

At the end of the file, comment the xconsole section:

#daemon.*;mail.*;\
#       news.err;\
#       *.=debug;*.=info;\
#       *.=notice;*.=warn       |/dev/xconsole

Restart rsyslog:

sudo service rsyslog restart

Installing Centreon Syslog plugin on Ubuntu 10.04 LTS Edit

The installation process is little sipmler with Ubuntu 10.04 LTS as rsyslog is already integrated.
You’ll notice that the installation process is almost the same as the old one.

You will need Centreon-Syslog installation files. Please go to http://forge.centreon.com/ and register. You’ll be able to download sources after that:

http://forge.centreon.com/projects/list_files/centreon-syslog

Download the stable release (when I wrote, it was the 1.2.1 version). After getting the frontend and server files, transfer them on your server with WinSCP or any other tools you like.

WinSCP is available as setup or portable version http://winscp.net/eng/download.php Continue reading »
