Install the dependencies, download the package and install it. Restart the Webserver to activate the new apache config in /etc/httpd/conf.d/icinga-web.conf. Then connect to the MySQL database to setup a new user.

More about the package, here: http://epis.ch/dr

yum install php php-cli php-pear php-xmlrpc php-xsl php-pdo php-gd php-ldap php-mysql perl-Locale-PO
wget http://daniel.oetken.cc/files/icinga-web-1.5.2-1.el6.noarch.rpm
yum install icinga-web-1.5.2-1.el6.noarch.rpm
service httpd restart
mysql -u root -p

Execute these querys

CREATE DATABASE icinga_web;
 GRANT USAGE ON *.* TO 'icinga_web'@'localhost'
   IDENTIFIED BY 'icinga_web'
   WITH MAX_QUERIES_PER_HOUR 0
   MAX_CONNECTIONS_PER_HOUR 0
   MAX_UPDATES_PER_HOUR 0;
 GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, INDEX
   ON icinga_web.* TO 'icinga_web'@'localhost';
 FLUSH PRIVILEGES ;
 quit

Import the Database scheme

cd /usr/share/icinga-web/etc/schema/
mysql -u root -p icinga_web < mysql.sql

Change the Database connection credentials

vim /etc/icinga-web/databases.xml

Caution! Now you have two databases, “icinga” the first one, is for all the monitored data. The second one is for the new Web UI _only_! In the “database.xml” you have to configure BOTH!

If the Web UI is still not working, see the logfiles!

//var/log/icinga-web/*.log
/var/log/messages
/var/log/icinga/icinga.log
/var/log/httpd/error_log

If you still don’t have any clue why it’s not working check the icinga-web test wiki

Install HOWTO is coming soon!

Hey everyone,

today or more yesterday, anyway, on Tuesday I went to an optical store to get new contact lenses. So they measured my visual acuity and the shocking news is it got worse. Before, I had -1.00 on both eyes and now my right eye has -1.75 and the left one -2.25. I bought 2-week lenses and finally I can see totally clear again

That’s it. Good night everyone.

What happend in this year? I will check it out, the website tells me

i-MSCP 1.0.1.5 (beta5) released

Posted on 25/10/2011

Ok, no stable yet, but seems not far from here.
What did they say one year ago?

After you installed icinga, you might want to install the new Web UI as well. As far as I know, there are no RPM packages for icinga-web available in the common repositories (for me these are the defaults + rpmforge + epel: Use it at your own risk, for more information about the repositories read: CentOS Wiki), but I didn’t really search for it, so maybe I just missed it. Feel free to post comments.

Install icinga-web 1.5.2 on CentOS 6.0

cd /usr/local/src/
wget http://sourceforge.net/projects/icinga/files/icinga-web/1.5.2/icinga-web-1.5.2.tar.gz/download
tar -zxf icinga-web-1.5.2.tar.gz
yum install php php-cli php-pear php-xmlrpc php-xsl php-pdo php-gd php-ldap php-mysql

./configure --prefix=/usr/local/icinga-web --with-web-user=apache --with-web-group=apache --with-web-path=/icinga-web --with-web-apache-path=/etc/httpd/conf.d --with-db-type=mysql --with-db-host=localhost --with-db-port=3306 --with-db-name=icinga_web --with-db-user=icinga_web --with-db-pass=icinga_web --with-conf-folder=etc/conf.d --with-log-folder=log

make install

make testdeps

You don’t have to use this “configure” command with all these options, but it’s nice to have, easy to understand and easily customizable, see a list of all options with

./configure --help

create MySQL user and database:

#> mysql -u root -p
 mysql> CREATE DATABASE icinga_web;
 GRANT USAGE ON *.* TO 'icinga_web'@'localhost'
   IDENTIFIED BY 'icinga_web'
   WITH MAX_QUERIES_PER_HOUR 0
   MAX_CONNECTIONS_PER_HOUR 0
   MAX_UPDATES_PER_HOUR 0;
 GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, INDEX
   ON icinga_web.* TO 'icinga_web'@'localhost';
 FLUSH PRIVILEGES ;
 quit

Import the database scheme with the following command! Answer the question with “y” if you used the correct database credentials in the “configure” statement already. Otherwise choose “n” and type in the correct data manually.

make db-initialize

cp /usr/local/src/icinga-web-1.5.2/etc/apache2/icinga-web.conf /etc/httpd/conf.d/
service httpd restart

If you want to change the database connection data later, edit the file

/usr/local/icinga-web/etc/conf.d/databases.xml

Caution! Now you have two databases, “icinga” the first one, is for all the monitored data. The second one is for the new Web UI _only_! In the “database.xml” you have to configure BOTH!

If the Web UI is still not working, see the logfiles!

/usr/local/icinga-web/log/*.log
/var/log/messages
/var/log/icinga/icinga.log
/var/log/httpd/error_log

If you still don’t have any clue why it’s not working check the icinga-web test wiki

Icinga 1.5.1 installation on CentOS 6.0 - using the RPM files

//UPDATE 14/11/2011 – 10:22 PST: You will find the RPM packages in the RPMforge repository: Repoforge RPMforge // Use it at your own risk, for more information about the repositories read: CentOS Wiki)

yum install icinga icinga-idoutils icinga-gui libdbi-dbd-mysql

It’s automatically added to the default runlevels.

create MySQL user and database:

#> mysql -u root -p
 mysql> CREATE DATABASE icinga;
 GRANT USAGE ON *.* TO 'icinga'@'localhost'
   IDENTIFIED BY 'icinga'
   WITH MAX_QUERIES_PER_HOUR 0
   MAX_CONNECTIONS_PER_HOUR 0
   MAX_UPDATES_PER_HOUR 0;
 GRANT SELECT , INSERT , UPDATE , DELETE
   ON icinga.* TO 'icinga'@'localhost';
 FLUSH PRIVILEGES ;
 quit

Please change the mysql data to your own!

Import database scheme for MySQL:

#> cd /etc/icinga/idoutils/mysql
#> mysql -u root -p icinga < mysql.sql

Change the mentioned database options in this file.

vim /etc/icinga/ido2db.cfg

db_servertype=mysql
db_port=3306
db_user=icinga
db_pass=icinga

Install basic modules.

UPDATE 18/11/2011 – 12:38 PST: added RPM Package install

From RPM Package

yum install nagios-plugins

change path in

/etc/icinga/resource.cfg
to
/usr/lib/nagios/plugins/

From Sources

http://sourceforge.net/projects/nagiosplug/files/nagiosplug/1.4.15/

wget http://sourceforge.net/projects/nagiosplug/files/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz/download
tar -zxf nagios-plugins-1.4.15.tar.gz
cd nagios-plugins-1.4.15
./configure --prefix=/usr/share/icinga \
--with-cgiurl=/icinga/cgi-bin --with-htmurl=/icinga \
--with-nagios-user=icinga --with-nagios-group=icinga

If the configure command is not working, see my other post: CentOS “build-essentials” – http://epis.ch/dd

make
make install
vim /etc/icinga/resource.cfg

change the line, because this is the path where the plugins are!

$USER1$=/usr/share/icinga/libexec

Next steps

The webinterface has a .htaccess protection enabled, but without any user! So you have to create one.

vim /etc/icinga/htpasswd.users

Use this following line to have username = “icingaadmin” and password set to “icinga”

icingaadmin:{SHA}8XLF6eTYQKVTVogqK2RIRrMCshY=

disable SELinux, otherwise the Classic UI doesn’t work!

vim /etc/sysconfig/selinux

change line to

SELINUX=disabled

Now reboot the machine!

After that you can login to the Classic UI on http://localhost/icinga with username=icingaadmin/passwort=icinga

Source: icinga Documentation – http://docs.icinga.org/

As there is no “build-essentials” package in CentOS you can install the stuff that you need for compiling software with:

yum install gcc gcc-c++ kernel-devel make

//UPDATE 10/11/2011 – 10:08 PST: added make to install list

The server I set up yesterday had a another weird problem. If you want to reboot the server after working several hours, the server just hangs and doesn’t shutdown properly. So today I took a closer look and now problem is gone but I’m not quite sure what was wrong.

I disabled some Bios options and in the end I plugged of the monitor. It’s really weird, because the reboot works properly if you turn the server on and reboot it right after it’s completely booted. If you work for some hours and try to reboot it then, it won’t work.

I also removed the grub boot options “rhgb” and “quiet” in the kernel line, that removes the splashscreen from the boot process, to see what’s going on.

Anyway, I’m glad the problem is gone.

There is also a forum entry where the problem sounds similar to mine: http://epis.ch/dc

Just for remembering the commands, because every time I need it, I have to search for it again.

# openssl genrsa -out daniel.oetken.cc.key 2048
# openssl req -new -key daniel.oetken.cc.key -out daniel.oetken.cc.csr

That’s all
