Installing a poller from packages on Debian 11 using Centreon 21.10

 

Pre-installation steps

 

Server name

If you want, you can change the server's name using the following command:

sudo hostnamectl set-hostname <new-server-name>

Replace <new-server-name> by the name you want. Example:

sudo hostnamectl set-hostname poller1

 

Install the repositories

To install Centreon software from the repository, you should first install the centreon-release package, which will provide the repository file.

1. Install curl and gnugp2:

sudo apt-get update && sudo apt-get install wget gnupg2

2. Run the following command with a privileged user:

su -
echo 'deb https://apt.centreon.com/repository/centreon-bullseye/ bullseye main' > /etc/apt/sources.list.d/centreon.list
exit

3. Download the GPG Key:

sudo wget -O- https://apt-key.centreon.com | gpg --dearmor | tee /etc/apt/trusted.gpg.d/centreon.gpg

4. Update the list of Debian packages:

sudo apt update

 

Installation

 

1. To install the monitoring engine, run the command:

sudo apt-get install centreon-broker centreon-broker-cbmod centreon-broker-core centreon-clib centreon-common centreon-connector centreon-connector-perl centreon-connector-ssh centreon-engine centreon-engine-extcommands centreon-gorgone centreon-perl-libs libzmq-constants-perl zmq-libzmq4-perl

2. To make services start automatically during system bootup, run the following command:

sudo systemctl enable centreon centengine

3. (temporary) Create missing sudoers:

su -
vim /etc/sudoers.d/centreon

Then copy the following lines:

## BEGIN: CENTREON SUDO

User_Alias      CENTREON=%centreon
Defaults:CENTREON !requiretty

CENTREON   ALL = NOPASSWD: /usr/bin/systemctl reload cbd

## END: CENTREON SUDO

Save and quit root user:

exit

4. (temporary) Apply missing rights:

sudo chown -R centreon-engine:centreon-gorgone /etc/centreon-engine/
sudo chmod -R g+w /etc/centreon-engine/

sudo chown -R centreon-broker:centreon-gorgone /etc/centreon-broker/
sudo chmod -R g+w /etc/centreon-broker/

sudo chown -R centreon:centreon /var/cache/centreon
sudo chmod -R g+w /var/cache/centreon

5. Restart Centreon Engine:

sudo systemctl restart centengine gorgoned

6. Then Add a Poller to configuration by selecting Add a Centreon Poller then Create new Poller  from the Centreon official documentation.

 

Don’t forget to install any Centreon Plugins you need, using:

sudo apt-get install centreon-plugin-<plugin_name>

 

Thanks a lot for this post.

In my lab environment, I had to adapt the groups for the centreon-engine and centreon-gorgone user

adduser centreon-gorgone centreon-engine
adduser centreon-gorgone centreon-broker
adduser centreon-engine centreon
adduser centreon-engine centreon-broker

After plugin installed, I had to create and change the ownership of the  directory  /var/lib/centreon/centplugins

mkdir -p /var/lib/centreon/centplugins
chown centreon: /var/lib/centreon/centplugins
chmod 775 /var/lib/centreon/centplugins

Finally, I had to change the permissions of all Centreon plugins that are not executable during their installation

I tested with a Central with Debian but I have errors with Gogorne. I test with a Central with CentOS

it’s OK with CentOS :wink:
 

 

@kermith72 yes a Central with Debian is still in progress.

@Pascal release 2 is now available, can you try?

Hi,

Thank you for this information.

I tried the installation process again.

I still have the problem regarding the centreon-gorgone user: 

root@poller:~# id centreon-gorgone
uid=112(centreon-gorgone) gid=120(centreon-gorgone) groups=120(centreon-gorgone),117(centreon)

It is not possible to write to centengine.cmd

2021-11-24 15:17:06 - ERROR - -engine] Command file '/var/lib/centreon-engine/rw/centengine.cmd' must be writeable

Centreon-engine user is OK :

root@poller:~# id centreon-engine
uid=110(centreon-engine) gid=118(centreon-engine) groups=118(centreon-engine),117(centreon),119(centreon-broker),120(centreon-gorgone)

I still have the issue with centplugin directory :

root@poller:~# ls /var/lib/centreon/centplugins
ls: cannot access '/var/lib/centreon/centplugins': No such file or directory

Concerning plugin, I install monitoring-plugins-basic to have check_icmp script.

Plugins are still not executable

root@lancelot:~# ls -al /usr/lib/centreon/plugins/centreon_linux_snmp.pl
-rw-r--r-- 1 root root 584238 Nov 22 21:05 /usr/lib/centreon/plugins/centreon_linux_snmp.pl

 

@Pascal release 2 is now available, can you try?

Hi,

Thank you for this information.

 

Hello Pascal,

Very thanks for you feedback, We will be working on these fixes and others I found here, soon we'll do another build. :wink:

Hi, @lgcosta 

Is there any update on this?

Hi there,

 

Just tried this tutorial and everything went fine. Didn’t run into errors and yet the poller doesn’t come up as running on the central interface.

Despite the fact that both gorgoned and centengine are running fine on the poller.

To add more context we are running on Centreon-HA 2 nodes CentOS 7 with a 21.10 versions. Maybe I missed something.

 

Hi.

I’m not able to install centreon on Debian 11. I’ve follwed the steps but all I get is an apt-key error

wget -O- https://apt-key.centreon.com  | gpg --dearmor | tee /etc/apt/trusted.gpg.d/centreon.gpg

Hello,


We have the same GPG key problem. Last week it was working well.

Do you know if a new public key will be release soon ? 

 

Thanks.

Hi @RomainD , yes the GPG key change for Centreon 22.04 packages.

We are finishing some fix before to start a new beta phase with this version.

 

Hi @Laurent,

 

We are running on Centreon-HA 2 nodes CentOS 7 with a 21.10 versions.

Can we always download Centreon Poller 21.10 with debian 11 ? Or poller 22.04 is compatible with Central 21.10 ? 

 

You should keep the same major version.

Centreon-HA is available as *.deb with 22.04 version.

Regards,

Today I got the newsletter for 22.04 release and the blog posts says it is fully compatible with debian 11. But is there any documentation on how install centreon-central with packages on debian 11? On docs.centreon.com is nothing so far. 

Regards

From https://www.centreon.com/en/blog/whats-new-in-the-latest-centreon-22-04-version :

With software version 22.04, we’ve completed the full packaging of Centreon for the Debian 11 Linux distribution.

Our Quality Assurance team is in the process of testing this new distribution to its full extent. As soon as testing is successfully completed, Debian packages will be made available to open-source users or commercial editions customers.

Watch The Watch to be informed of the exact release date.

 

It is therefore not yet available

. sorry, my mistake
