So here we go...
After installing your base server and Logging in, the first thing we need to do is install some prerequsistes that Centreon will neeed to run correctly:
~ $ sudo -s
~ # aptitude update
~ # aptitude upgrade
~ # tasksel *Select Lubuntu minimal Install
~ # aptitude install leafpad
~ # aptitude install chromium-browser
~ # aptitude install sysutils mailx lsb-release postfix mailutils
~ # aptitude install build-essential
~ # aptitude install apache2 apache2-mpm-prefork
~ # aptitude install php5 php5-mysql php-pear php5-ldap php5-snmp php5-gd php-gettext
~ # aptitude install mysql-server libmysqlclient15-dev
~ # aptitude install rrdtool librrds-perl
~ # aptitude install libconfig-inifiles-perl libcrypt-des-perl libdigest-hmac-perl torrus-common libgd-gd2-perl
~ # aptitude install snmp snmpd libnet-snmp-perl libsnmp-perl
~ # aptitude install libgd2-xpm libgd2-xpm-dev libpng12-dev
~ # aptitude install phpMyAdmin
Edit /etc/snmp/snmptrapd and change the value of TRAPDRUN from no to yes in /etc/default/snmpd
~ # reboot
Now we need to create a user on the server named nagios, place this user in the proper groups it will need access to:
~ # /usr/sbin/useradd -m nagios
~ # passwd nagios
~ # /usr/sbin/groupadd nagcmd
~ # /usr/sbin/usermod -G nagios,nagcmd nagios
~ # /usr/sbin/usermod -G nagios,nagcmd www-data
Now lets install Nagios, along with the plug-in's you will need for Centreon:
~ # cd /usr/local/src/
~ # wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.4.1.tar.gz
~ # tar xvzf nagios-3.4.1.tar.gz
~ # cd nagios-3.4.1/
~ # ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --enable-nanosleep --enable-event-broker
~ # make all
~ # make install
~ # make install-init
~ # make install-commandmode
~ # make install-config
~ # update-rc.d -f nagios defaults
~ # chmod +x /etc/init.d/nagios
~ # cd /usr/local/src/
~ # wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.15.tar.gz
~ # tar xvzf nagios-plugins-1.4.15.tar.gz
~ # cd nagios-plugins-1.4.15/
~ # ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl=/usr/bin/openssl
~ # make
~ # make install
Install NDO:
~ # aptitude install subversion
~ # cd /usr/local/src/
~ # wget http://prdownloads.sourceforge.net/sourceforge/nagios/ndoutils-1.4b9.tar.gz
~ # tar xvzf ndoutils-1.4b9.tar.gz
~ # cd ndoutils-1.4b9
~ # wget http://svn.centreon.com/trunk/ndoutils-patch/ndoutils1.4b9_light.patch
~ # patch -p1 -N < ndoutils1.4b9_light.patch
~ # ./configure --prefix=/usr/local/nagios/ --enable-mysql --disable-pgsql \
--with-ndo2db-user=nagios --with-ndo2db-group=nagios
~ # make
~ # cp ./src/ndomod-3x.o /usr/local/nagios/bin/ndomod.o
~ # cp ./src/ndomod-3x.o /usr/sbin/ndomod.o
~ # cp ./src/ndo2db-3x /usr/local/nagios/bin/ndo2db
~ # cp ./config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
~ # cp ./config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
~ # chmod 774 /usr/local/nagios/bin/ndo*
~ # chown nagios:nagios /usr/local/nagios/bin/ndo*
~ # cp ./daemon-init /etc/init.d/ndo2db
~ # update-rc.d ndo2db defaults
~ # chmod +x /etc/init.d/ndo2db
Now we are ready to install Centreon itself:
~ # cd /usr/local/src/
~ # wget http://download.centreon.com/centreon/centreon-2.3.8.tar.gz
~ # tar xvzf centreon-2.3.8.tar.gz
~ # cd centreon-2.3.8/
~ # export PATH="$PATH:/usr/local/nagios/bin/"
~ # sudo ./install.sh -i
Scroll to the bottom of the license agreement and accept by clicking "Y ". Answer "Y" for all questions during installation and validate all default paths during installation.
~ # /etc/init.d/apache2 reload
Now load http://YouIP/centreon and follow the wizard to finish the install, on step 6, make sure you have the MySQL database setting correct. Once your finished you should be able to log in with the account you created. Once you are loged in, go to: Configuration→Nagios and check the Boxs "Move Export Files" and Restart Nagios" and then click the [export] button
From the command line run the following commands:
~ # /etc/init.d/nagios start
~ # /etc/init.d/ndo2db start
Your Installation should now start reporting on the basic status of your server. Next time I'll tell you how to start adding other servers in your enviroment to the list of monitered servers.
Hello,
ReplyDeleteI following the instructions, but i cant add hosts to centreon list. When i add a host and save its come back to hosts list and dont appear anything.
Tks

It's very important that you start these services in the correct order, if you don't you will have the problem you describes.
Also you need to restart the Nagios service every time you add a server also:
(Go to: Configuration→Nagios and check the Boxs "Move Export Files" and "Restart Nagios" and then click the [export] button)
Do this after every server you add
Steve, it worked like a charm :-)
ReplyDeleteNow I have a weird question for you: I'd like to offer RMM for some of our small/medium business customers. I can't wrap my head around how to set them up as separate entities in Centreon. In other words, I want Customer A to be able to log in and see their "stuff" but nobody else's "stuff." I'm stuck at how to configure that. Can you help?
Hey, sorry it took me so long to answer back, I don't log in very often. As to the question, I don't think can answer that question, I've never done that with my server. I'd have to do some research. If you have figured it out please post and share. I'd like to know the answer myself. :-)
ReplyDeleteHello Steve.
ReplyDeleteThanks a lot for you tutorial.
I've followed it without problems, until I've reached "7 - Installation" into WebGUI...
Now it reply with this error:
Configuration database OK
Storage database OK
Utils database OK
Creating database user Query was empty
Anyone know a way to solve the problem?
Thanks
Daniele
That looks like a PHP error, are you sure you have PHP installed correctly?
ReplyDeleteHi Steve,
ReplyDeleteWhen I try to restart Nagios from Centreon it shows the following error:
Nagios Core 3.4.1

Reading configuration data...
Error in configuration file '/usr/local/centreon/filesGeneration/nagiosCFG/1/nagiosCFG.DEBUG' - Line 28 (UNKNOWN VARIABLE)
Error processing main config file!
***> The name of the main configuration file looks suspicious...
Make sure you are specifying the name of the MAIN configuration file on
the command line and not the name of another configuration file. The
main configuration file is typically '/usr/local/nagios/etc/nagios.cfg'
***> One or more problems was encountered while processing the config files...
Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.
Great Tutorial anyway.
Regards
hmm I'm note sure what that means..
Deletewhat is on line 28 of '/usr/local/centreon/filesGeneration/nagiosCFG/1/nagiosCFG.DEBUG'
Hallo,
ReplyDeleteI tryed some installation guides and yours is the best!
But I have a big problem:
the centstorge libs ar not installed.
Where is your CentStorage RRD directory
default to [/var/lib/centreon]
>
Path /var/lib/centreon OK
Finding Nagios group : nagios
Finding Nagios user : nagios
Preparing Centreon temporary files
/tmp/centreon-setup exists, it will be moved...
install www/install/createTablesCentstorage.sql OK
CentStorage status Directory already exists PASSED
CentStorage metrics Directory already exists PASSED
Change macros for centstorage binary OK
Install CentStorage binary OK
Install library for centstorage FAIL
Change right : /var/run/centreon OK
Change macros for centstorage init script OK
Do you want me to install CentStorage init script ?
[y/n], default to [n]:
>
So I tryed: Move centreon form /usr/local/src/ to /tmp/ --> found here http://forum.centreon.com/showthread.php/11364-Problems-during-installation-upgrade-2-1-12-to-2-2-0
But it doesn't work!
What am I doing work?
And after login into localhost/centreon/ I get a fully emty page!
